This boiler has a limited warranty, a copy of which is printed on the back of this manual.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is complete. The warranty for this boiler is valid only if the boiler
has been installed, maintained and operated in accordance with these instructions.

DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity of this or any other
appliance.
If you smell gas or fuel oil vapors, do not try to operate the burner/boiler system. Do not touch any
electrical switch or use any phone in the building. Immediately call the gas or oil supplier from a remotely
located phone.
Burner/boiler systems produce steam or hot water in a pressurized vessel by mixing extremely flammable
gaseous, liquid or solid fuels with air to produce combustion and very hot products of combustion.
Explosions, fires severe personal injury, death and/or property damage will result from improper, careless
or inadequate installation, operation or maintenance of fuel-burning and boiler equipment.

Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal
injury or loss of life. Failure to follow all instructions in the proper order can cause personal injury or
death. Read and understand all instructions, including all those contained in component manufacturers
manuals which are provided with the appliance before installing, starting-up, operating, maintaining or
servicing this appliance. Keep this manual and literature in legible condition and posted near appliance
for reference by owner and service technician.
This boiler requires regular maintenance and service to operate safely. Follow the instructions contained
in this manual.
Installation, maintenance, and service must be performed only by an experienced, skilled and knowledgeable
installer or service agency.
All heating systems should be designed by competent contractors and only persons knowledgeable in
the layout and installation of hydronic heating systems should attempt installation of any boiler.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is completed.
Installation is not complete unless a pressure relief valve is installed into the specified tapping on the
supply manifold located on top and at rear of appliance - See Section III, Paragraph 33, ‘e’ of this manual
for details.
This boiler is NOT suitable for installation on combustible flooring.
Do not tamper with or alter the boiler or controls. Retain your contractor or a competent serviceman to
assure that the unit is properly adjusted and maintained.
Clean boiler at least once a year - preferably at the start of the heating season to remove soot and scale.
The inside of the combustion chamber should also be cleaned and inspected at the same time.
Have Burner and Controls checked at least once a year or as may be necessitated. Do not operate
unit with jumpered or absent controls or safety devices. Do not operate unit if any control, switch,
component, or device has been subject to water.

Appliance materials of construction, products of combustion and the fuel contain alumina, silica, heavy
metals, carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful substances which
can cause death or serious injury and which are known to the state of California to cause cancer, birth
defects and other reproductive harm. Always use proper safety clothing, respirators and equipment when
servicing or working nearby the appliance.
This boiler contains very hot water under high pressure. Do not unscrew any pipe fittings nor attempt
to disconnect any components of this boiler without positively assuring the water is cool and has no
pressure. Always wear protective clothing and equipment when installing, starting up or servicing this
boiler to prevent scald injuries. Do not rely on the pressure and temperature gauges to determine the
temperature and pressure of the boiler. This boiler contains components which become very hot when
the boiler is operating. Do not touch any components unless they are cool.
This appliance must be properly vented and connected to an approved vent system in good condition.
Do not operate boiler with the absence of an approved vent system.
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
The interior of the venting and air intake systems must be inspected and cleaned before the start of the
heating season and should be inspected periodically throughout the heating season for any obstructions.
Clean and unobstructed venting and air intake systems are necessary to allow noxious fumes that could
cause injury or loss of life to vent safely and will contribute toward maintaining the boiler’s efficiency.
This boiler is supplied with controls which may cause the boiler to shut down and not re-start without
service. If damage due to frozen pipes is a possibility, the heating system should not be left unattended in
cold weather; or appropriate safeguards and alarms should be installed on the heating system to prevent
damage if the boiler is inoperative.
This boiler is designed to burn natural and/or LP gas only. Do not use gasoline, crankcase drainings, or
any oil containing gasoline. Never burn garbage or paper in this boiler. Do not convert to any solid fuel
(i.e. wood, coal). All flammable debris, rags, paper, wood scraps, etc., should be kept clear of the boiler
at all times. Keep the boiler area clean and free of fire hazards.
Float type low water cutoff devices require annual inspection and maintenance. Refer to instructions in
Section V, Paragraph 7 for inspection and cleaning instructions.

Series 5B cast iron boilers are designed, built, marked and tested in accordance with the ASME Boiler and
Pressure Vessel Code, Section IV, Heating Boilers. An ASME Data Label is factory applied to each Series 5B
jacket, which indicates the boiler Maximum Allowable Working Pressure (MAWP). Each cast iron section is
permanently marked with the MAWP listed on the boiler’s ASME Data Label. Those values for the Series 5B
are as follows:
MAWP, Water - 50 PSI
MAWP, Steam - 15 PSI

SECTION I – EQUIPMENT CHECK LIST
U.S.A. EQUIPMENT CHECK LIST
(For Canadian Equipment Check List, Turn to Pages 7 and 8)

		This Equipment Check List has been provided so that the Installer can determine if all parts have been provided for the boiler ordered.
It covers standard equipment for both steam and water boilers without Tankless Heaters. Heaters or optional equipment ordered will be in
addition to, or in lieu of, equipment shown below.

		
By opening cartons in numerical sequence, boiler assembly is simplified. If there is an exception, it will be pointed out in the boiler
assembly procedure. When it does occur, you will find that assembly of the boiler is further simplified.

SECTION II – GENERAL INFORMATION
1. 	BOILER INSTALLATION must conform to the

requirements of the authority having jurisdiction, or in
the absence of such requirements, to:
USA – “National Fuel Gas Code, ANSI Z223.1”.
When required by the authority having jurisdiction,
the installation must conform to American Society of
Mechanical Engineers Safety Code for Controls and
Safety Devices for Automatically Fired Boilers, No.
CSD-1.
CANADA – “Installation Codes for Natural and
Propane Gas Burning Appliances and Equipment,
CAN/CSA-B149 (.1 or .2)”.
DO NOT INSTALL THIS BOILER ON CARPETING.

	
	

	
	

2. 	 BOILER LOCATION – locate on a level NON-

COMBUSTIBLE FLOOR as close as possible to
chimney so that vent connection is short and direct.

Boiler must not be installed directly on
combustible flooring. A concrete pad is not
sufficient to protect combustible flooring.
	

	

	

The boiler shall be installed such that the gas ignition
system components are protected from water (dripping,
spraying, rain, etc.) during boiler operation and service
(circulator replacement, control replacement, etc.).
Do not install boiler where gasoline or other flammable
vapors or liquids, or sources of hydrocarbons (i.e.
bleachers, cleaners, chemicals, sprays, paint removers,
fabric softeners, etc. ) are used or stored.
Refer to table below for minimum clearances, service
clearances, and clearances for removal of Tankless
Heaters.

3. 	PROVIDE COMBUSTION AND VENTILATION
AIR.

	

In the USA refer to National Fuel Gas Code, NFPA
54/ANSI Z223. Section 5.3, Air for Combustion and
Ventilation. In Canada refer to Natural Gas Installation
Code, CAN/CSA-B149.1 – latest edition or Propane
Installation Code, CAN/CSA-B149.2 – latest edition.
Local code provisions may apply and should be
referenced.

Adequate combustion and ventilation air must be
provided to assure proper combustion.
a. 	Determine volume of space (boiler room). Rooms
communicating directly with the space, in which
the appliances are installed, through openings not
furnished with doors, are considered a part of the
space.
		Volume (ft³) = Length (ft) x Width (ft) x Height (ft)
b. 	Determine total input of all appliances in the space.
Add inputs of all appliances in the space and round
the result to the nearest 1000 Btu per hour.
c. 	Determine type of space.
		Divide Volume by Total Input of all appliances
in space. If the result is greater than or equal to
50 ft³/1000 Btu per hour, then it is considered an
unconfined space.
	

If the result is less than 50 ft³/1000 Btu per hour,
then the space is considered a confined space.

d. 	For boiler located in an unconfined space of a
conventionally constructed building, the fresh
air infiltration through cracks around windows
and doors normally provides adequate air for
combustion and ventilation.
e. 	For boiler located in a confined space or an
unconfined space in a building of unusually tight
construction, provide outdoor air with the use
of two permanent openings which communicate
directly or by duct with the outdoors or spaces
(crawl or attic) freely communicating with the
outdoors. Locate one opening within 12 inches of
top of space. Locate remaining opening within 12
inches of bottom of space. Minimum dimension
of air opening is 3 inches. Size each opening per
following:
1. Direct communication with outdoors. Minimum
free area of 1 square inch per 4,000 Btu per hour
input of all equipment in space.
2. Vertical ducts. Minimum free are of 1 square
inch per 4,000 Btu per hour input of all

CLEARANCES - From Table below and from dimensional data in Fig. 1, determine BOILER ROOM space necessary for appropriate access
to and servicing of Boiler. Consideration should be given to other appliances installed in the same area. Consult with local Building and
Safety Codes for compliance.

SECTION II – GENERAL INFORMATION (continued)
equipment in space. Duct cross-sectional area
shall be same as opening free area.
3. 	Horizontal ducts. Minimum free area of 1
square inch per 2,000 Btu per hour input of all
equipment in space. Duct cross-sectional area
shall be same as opening free area.
	 Alternate method for boiler located within
confined space. Use indoor air if two permanent
openings communicate directly with additional
space(s) of sufficient volume such that combined
volume of all spaces meet criteria for unconfined
space. Size each opening for minimum free area
of 1 square inch per 1,000 Btu per hour input of
all equipment in spaces, but not less than 100
square inches.

4. 	 Louvers and Grilles of Ventilation Ducts
	

All outside openings should be screened and louvered.
Screens used should not be smaller than ¼ inch mesh.
Louvers will prevent the entrance of rain and snow.
a. 	Free area requirements need to consider the blocking
effect of louvers, grilles, or screens protecting the
openings. If the free area of the louver or grille
is not known, assume wood louvers have 20-25
percent free area and metal louvers and grilles have
60-75 percent free area.
b. 	Louvers and grilles must be fixed in the open
position or interlocked with the equipment to open
automatically during equipment operation.

SECTION III – INSTALLATION INSTRUCTIONS
f. 	Base must be level in both directions and secure on
the floor. Shim and grout under Base if necessary.
g. 	Place cardboard covering over the top of the burner
assembly to protect them during the assembly of the
boiler sections.

2. 	 CLEAN BOILER SECTIONS inside and out to remove
dirt due to shipment and handling.

	

Open Tie Rod Bundle(s). Open Draw-up Rod
Bundle(s).

	

Open Boiler Assembly Carton(s).

3. 	 SET LEFT END SECTION ON BASE so that locating

single base assembly, see Fig. 2.
b. 	5015B section thru 5026B section boilers require a
left and a right base subassembly, see Fig. 3.
	

	 Remove Base Assembly(s) From Skid(s)

c. 	Remove bolts securing Base Assembly(s) to
shipping skid(s) and place Base(s) in location where
Boiler is to be installed.
d. 	Join Base Sub-assemblies together (15 section &
larger boilers) by first removing upper shipping
strip and lower shipping angles from subassemblies.
Use (4) ¼”-20 x ¾” MS, nuts and washers to attach
subassemblies, see Fig. 3.
e. 	Attach Front Intermediate Jacket Panel Support
Bracket and Lower Rear Intermediate Panel Support
Bracket to lower channel on Front Base Frame and
Rear Base Frame, respectively, using (4) ¼”-20 x

lugs on bottom of section go inside Front and Rear Base
Frames. Slide section on base until these lugs strike
High Base End Panel at left end of Base, see Fig. 4.
(Note – if High Base End Panel is at right end of Base,
section assembly must start with Right End Section).
Left end sections are identified by “LEH” cast on
section; Right End Sections are identified by “REH”
cast on section.

4. 	CLEAN NIPPLES AND NIPPLE PORTS thoroughly

with a de-greasing solvent. Use the Loctite® #592
supplied to lubricate the nipples and nipple ports.
Apply the lubricant to the nipples and nipple ports, then
use a brush to disperse it evenly around the nipples and
the nipple ports. Use approximately 25 ml of Loctite®

c. 	Insert short end of draw-up rod through front & rear
nipple ports on both sections, see Fig. 5.
d. 	Place two (2) flat washers, draw-up channel and a
nut on each end of draw-up rods and finger tighten.
e. 	DRAW UP CENTER SECTION SLOWLY AND
EVENLY, tightening each DRAW-UP ROD a little
at a time so that sections are equally spaced. KEEP
NIPPLES ALIGNED WITH NIPPLE PORTS. If
necessary, tap Nipples lightly with a blunt tool or
rod to keep Nipples from cocking while Sections are
being drawn up. DO NOT DRAW UP SECTION(S)
WHEN NIPPLES ARE COCKED. Continue
tightening Draw-Up Rods equally until Sections
meet iron-to-iron on the ground surface. BUMPING
OUTER EDGES OF SECTION WITH WOODEN
BLOCK WILL EASE DRAW-UP OPERATION.
f. 		KEEP DRAW-UP ROD THREADS, NUTS AND
WASHERS LUBRICATED with grease or heavy oil
to prevent damage to rods and threads and to make
assembling easier.

g. 	Using a pinch bar, insert WOOD WEDGES
under last Center Section assembled so as to raise
it just above Boiler Base. This will keep the next
section to be assembled above the base, thus making
it easier to join and draw-up. MOVE WOOD
WEDGES FORWARD EACH time a Section has
been drawn up.

7.	 ASSEMBLE REMAINING END SECTION WITH

DRAW-UP RODS in a manner similar to that for
assembling Center Sections. Remove wedges from
under Boiler. Be sure Boiler is aligned and seated on
Base.
a. 	After section assembly is completed install 5/8” tie
rods from tie rod bundle through the upper lug holes
in the front of Boiler and Lower lug holes in the rear
of Boiler sections and tighten until they are finger
tight only, to allow for expansion. This is necessary
in order to allow clearance for installation of Flue
cover plates. Finally, remove ¾” draw-up rods from
nipple ports.

CLEARANCES – Steam and Hot water pipes shall
have clearances of at least ½” from all combustible
construction.

c. 	With COMBINATION HEATING AND COOLING
(REFRIGERATION) SYSTEMS having the same
Distributing Units, Piping and Circulator, See Fig.
17. For additional reference, consult ASHRAE
Systems Handbook 2008 Edition.

Before using copper for steam piping, consider
the following characteristics of copper piping:
1) high coefficient of thermal expansion can
induce mechanical stresses and cause expansion/
contraction noises if not accounted for in the
piping system design and installation,
2) high heat transfer rate (heat loss) of uninsulated
copper piping must be included in the normal
piping and pickup factors used to size the boiler,
3) soldering or brazing pastes and fluxes that end
up in the system can cause poor heat transfer,
surging, and unsteady water line and wet steam
if not thoroughly removed during the boil out
procedure and,
4) galvanic corrosion of the adjoining metal may
occur due to dissimilar metals in certain water
chemistries if dielectric unions are not used.

16

NOTE: When Hot Water Heating Boilers are
connected to Heating Coils located in Air Handling
Units where they may be exposed to refrigerated
air circulation, the Boiler Piping System must
be equipped with Flow Control Valves or other
automatic means to prevent gravity circulation of
the Boiler Water during the cooling cycle.

d. 	NOTE: Valves must be installed in the supply and
return branches to the Heating Boiler and Water
Chiller so as to prevent circulation of Chilled Water
through the Boiler or Heated Water through the
Chiller.
OXYGEN CORROSION:
	

Oxygen contamination of the boiler water will cause
corrosion of the iron and steel boiler components,
which can lead to failure. As such, any system must
be designed to prevent oxygen absorption in the first
place or prevent it from reaching the boiler. Problems
caused by oxygen contamination of boiler water are not
covered by Burnham’s standard warranty.

c. 		Install Gauge Glass Fittings into ends of tees used
to connect the 67BC-2 or 47-2 Control. If other
control is furnished, install Gauge Glass Fitting
directly into ½” pipe extensions.
d. 		Install Pressure Limit Controls as follows:
(1) 	Boiler equipped with 67BC-2 Low Water Cut-	
Off – Connect Pressure Limit furnished to ¼”
street ell and ¼” pigtail siphon. For installation
of second pressure limit (not furnished), bush
1½” pipe tapping in upper corner of End
Section. Connect Pressure Limit to this bushing
with ¼” pigtail siphon.
(2) 	Boiler equipped with Low Water Cut-Off other 	
than (1) above or with Low Water Cut-Off
Feeder Combination – Bush 1½” pipe tapping
in upper corner of End Section and connect
Pressure Limit furnished to this bushing with
¼” pigtail siphon. For installation of second
pressure limit bush any available tapping on
opposite end section that is above normal water
line. Connect Pressure Limit to this bushing
with ¼” pigtail siphon.
(3) 	Tighten limit controls by using wrench on hex 	
fitting at bottom of control.
(4) 	The L404 Pressuretrol must be accurately
leveled for proper operation. It is level when the
leveling indicator hangs freely with its pointer
directly over the index mark inside the back
of the case. Level the controller by carefully
bending the steam trap (siphon loop).
e. 		Install Pressure Safety Valve with fittings furnished,
into 1½” pipe tapping in upper corner of End

as Surface Blowoff, replace ell with tee and plug
open end of tee or valve off opening. Pressure
Safety Valve must be in leg of tee and in a vertical
position with handle up.
f. 		Install Boiler Drain Valve and 3” x ¾” Bushing into
one of the two return tappings. The drain valve
may also be installed in return piping, but it must
be installed in the leg of a tee so that it is directly
opposite and as close as possible to the return
tapping. The leg of the tee must be at least 1½” pipe
size.

A Bottom Blowoff using a valve must also be
connected to one of the return tappings. The ¾”
Drain Valve may be used for Bottom Blowoff for
5009B or smaller boilers, since any Bottom Blowoff
piping or valves for 5009B or smaller boilers must
be at least ¾”. Bottom Blowoff piping and valves
for Boilers 5010B through 5021B must be at least
1”. Bottom Blowoff piping and valves for 5022B
Boilers and larger must be at least 1¼”.

g. 		If boiler has been ordered with 3/8” try-valve
tapping, install try-cock.
h. 		Install “Lowest Permissible Water Level Plate”
and “Frequent Water Addition – Caution Label” on
upper left end jacket panel.
i. 		Proceed directly to Paragraph 36.

On boilers with Built-in Tankless Heater, install
operating control in ¾” tapping in Heater Plate-plug
tapping in Second Heater when supplied.
c. On boilers equipped for forced circulation hot
water heating without domestic hot water, a reverse
acting circulator control may be needed to prevent
condensation of flue gases during periods of low
boiler water temperature. This control can be
installed in the Tapped Heater Opening Cover Plate.
d. 		TANKLESS HEATER PERFORMANCE
		Tankless heater ratings in Series 5B boilers are
based on continuous draw, temperature rise of 100ºF
(40-140ºF) and boiler water temperature of 200ºF.
Some of the items affecting the coil performance are
as follows:
(1) 	FLOW REGULATION – If flow through the
heater is greater than its rating, the supply of
adequate hot water may not be able to keep
up with the demand. For this reason a FLOW
REGULATOR matching the heater rating should
be installed in the cold water line to the heater.
(2) 	FLUSHING OF HEATER - All water contains
some sediment which settles on the inside of
the coil. Consequently, the heater should be
periodically back-washed. This is accomplished
by installing hose bibs as illustrated in Fig. 30
and allowing water at city pressure to run into
hose bib A, through the heater, and out hose bib
B until the discharge is clear. The tees in which
the hose bibs are located should be the same size
as heater connections to minimize pressure drop.
(3) 	HARD WATER – This is applicable to some
city water and particularly to well water. This
should not be a deterrent but precautions are
necessary. A water analysis is necessary and an
appropriate water softener installed. This is not
only beneficial to the heater but to piping and
fixtures plus the many other benefits derived
from soft water.

Heater, install second temperature limit control (not
furnished) in Tapped Heater Opening Cover Plate.

	

NOTE: A hot water boiler installed above radiation
level must be provided with a low water cut-off
device as part of the installation.

Install automatic mixing valve at tankless heater
outlet to avoid risk of burns or scalding due to
excessively hot water at fixtures. Adjust and
maintain the mixing valve in accordance with the
manufacturers instructions.

furnished. Hence, the procedure for installing one set is
equally applicable to the second set.

	

PRESSURE TESTING of gas service piping must be
done before connecting to the boiler gas train. Test for
leaks by introducing, from an isolated source, air or
inert gas to the piping. Piping shall withstand 3 PSI
gage pressure for a period of not less than 10 minutes
without showing any drop in pressure.

SECTION III – INSTALLATION INSTRUCTIONS (continued)
37. A DRIP LEG SHOULD BE PROVIDED IN THE
	

	

	

VERTICAL DROP TO EACH GAS TRAIN, see
Fig. 1. An additional Manual Shut-off valve and
ground joint union, as show in Fig. 1, should be
installed in the piping to each gas train for ease of
servicing.
CONNECT GAS SERVICE FROM METER TO GAS
TRAIN in accordance with the requirements of the
authority having jurisdiction or, in the absence of such
requirements to the –
USA – “National Fuel Gas Code, ANSI Z223.1”.

	

CANADA – “Installation Codes for Natural and LP Gas
Burning Appliances and Equipment, CAN/B149.1 &

c. 		Length of piping in feet and number of elbows – for
practical purposes each 90º elbow can be considered
as the following equivalent in length of straight
pipe:

	

A pipe thread compound resistant to the action
of liquefied petroleum gases must be used on all
threaded joints in the gas piping.

	

Pressure testing of the Gas Supply Piping Boiler and
its connections is required before placing the boiler
in operation.

	

The boiler and shutoff valve must be disconnected
from the gas supply piping system during any
pressure testing at pressures greater than ½” psig.

	

The boiler must be isolated from the gas supply
piping system during any pressure testing at
pressures equal to or less than ½ psig.

	

WITH GAS SUPPLY “OFF” and Service Piping
connected to the boiler, open Manual Valve(s) and
pilot valve(s) at end of Gas Train(s) and reduce
pressure to ½ lb. gage pressure. Using soap solution
or other approved method check gas train piping,
pilot piping, bleed piping and orifices for leaks.

Venting

1. 	 INSTALL VENT CONNECTOR from canopy Draft

Hood or damper to chimney maintaining 6” clearances
from combustible materials.

2. 	 INSTALL VENT SYSTEM – Typical vent systems are

shown in Fig. 38 and 39. Some of the factors affecting
vent sizing and construction accompany these figures.

	

	

Vent installation shall be in accordance with local
building codes; or the local authority having
jurisdiction; or the National Fuel Gas Code, ANSI
Z223.1/NFPA 54; or the Standard for Chimneys,
Fireplaces, Vents and Solid Fuel Burning Appliances,
ANSI/NFPA 211. Both of the aforementioned
standards, ANSI Z223.1 and ANSI/NFPA 211,
specify Type B and Type L double wall metal vents
and fire clay tile lined masonry chimneys as suitable
chimney constructions for Category I, draft hood
equipped appliances, such as this Series 5B boiler.
Both standards prohibit the use of unlined masonry
construction as a chimney, with the exception in
ANSI Z223.1/NFPA 54 that “Where permitted by
the authority having jurisdiction, existing chimneys
shall be permitted to have their use continued when
an appliance is replaced by an appliance of similar
type, input rating and efficiency.” ANSI/NFPA 211
prohibits the use of single wall metal vent as a chimney,
while ANSI Z223.1 allows it under very restrictive
conditions.

Fig. 38
SINGLE VENT SYSTEM

In Canada, refer to CAN/CSA-B149.1 or .2-M86 and
local codes for venting.
SOME ITEMS RELATIVE TO CONSTRUCTION
AND SIZING OF VENT SYSTEM
(1) 	Total Vent Height.
(2) 	Vent Connector – make Initial Rise as high as 	
	 possible.
(3) 	Length of Lateral – hold to a minimum.
(4) 	Number of Elbows – hold to a minimum.
(5) 	UL Listed Vent Cap – assures full vent capacity 	
	 and freedom from adverse wind effects.
(6) 	Locate Boiler as close to Chimney as possible 	
	 consistent with necessary clearances, see page 10, 	
lower table.
(7) 	Run Breaching Horizontal and slope upward to 	
	 Chimney maximum of ¼” per ft.
(8) 	Use thimble where Breaching enters masonry 	
	 chimney – keep breaching flush with inside of flue 	
	 liner – do not connect into same leg of chimney 	
	 serving an open fireplace.
(9) 	Install vent above bottom of Chimney to prevent 	
	 blockage – inspect chimney for obstructions 		
	 or restrictions and remove – clean chimney if 	
	 necessary.

Fig. 39
MANIFOLD VENT SYSTEM
(10) Provide cleanout in chimney.
(11) 	Slip joint or draw band – facilitates installation and 	
	 future servicing when necessary.
(12) 	Venting of other appliances into same chimney
			 or into a common vent will affect sizing of the 	
	 chimney or common vent.
(13) 	Correction for altitude – design vent system for sea 	
	 level input.
(14) 	Provide adequate ventilation of Boiler Room, see 	
	 page 10 – this cannot be overemphasized.
(15) 	Never pass any portion of a vent system thru a 	
	 circulating air duct or plenum.
(16) 	Support of lateral runs so that vent pipe does not 	
	 sag.
(17) 	Support of common vent where it passes thru a 	
	 ceiling or roof.

41

SECTION III – INSTALLATION INSTRUCTIONS (continued)
(18) 	Clearances to combustible material – use of 		
	 thimbles.
(19) 	Firestops.
(20) 	Flashing and storm collars.
(21) 	Guying or bracing of common vent pipe above 	
	 roof.
(22) 	Securing and gas tightness of joints.
(23) 	Lightning arrester if top of metal vent is one of 	
	 highest points on the roof.
	

Where choice is possible, many advantages can be
listed for the UL Listed double wall metal type B vent:

1. 	Warm up is faster with type B vents than vents
having greater mass.
2. 	Type B vents permit closer clearance to
combustible material than single wall metal 	
vents unless special precautions are taken with
the latter.
3. 	Type B vents are less prone to condensation and
corrosion than single wall metal vents.
4. 	Type B vents are lightweight, easy to handle and
assemble.

When an existing boiler is removed from a common venting system, the common venting
system is likely to be too large for proper venting of the appliances remaining connected
to it. At the time of removal of an existing boiler, the following steps shall be followed
with each appliance remaining connected to the common venting system placed in operation,
while the other appliances remaining connected to the common venting system are not
in operation.
A. Seal any unused openings in the common venting system.
B. Visually inspect the venting system for proper size and horizontal pitch and determine
there is no blockage or restriction, leakage, corrosion and other deficiencies which
could cause an unsafe condition.
C. Insofar as is practical, close all building doors and windows and all doors between
the space in which the appliances remaining connected to the common venting system
are located and other spaces of the building. Turn on clothes dryer and any appliance
not connected to the common venting system. Turn on any exhaust fans, such as
range hoods and bathroom exhausts, so they will operate at maximum speed. Do not
operate a summer exhaust fan. Close fireplace dampers.
D. Place in operation the appliance being inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate continuously.
E. Test for spillage at the draft hood relief opening after 5 minutes of main burner
operation. Use the flame of a match or candle, or smoke from a cigarette, cigar or
pipe.
F. After it has been determined that each appliance remaining connected to the common
venting system properly vents when tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and other gas burning appliance to their previous
conditions of use.
G. Any improper operation of the common venting system should be corrected so the
installation conforms with the National Fuel Gas Code, ANSI Z223.1. When resizing any
portion of the common venting system, the common venting system should be resized
to approach the minimum size as determined using the appropriate tables in Chapter
10 in the National Fuel Gas Code, ANSI Z223.1.

SECTION IV - OPERATION
	

Safe lighting and other performance criteria were met with the gas manifold and control assembly provided on the boiler
when the boiler underwent tests specified in ANSI Z21.13.

1. GENERAL
a. INITIAL FILL – Before putting water into a new
boiler, make certain that the firing equipment is in
operating condition to the extent that this is possible,
without actually firing into an empty boiler. This
is necessary because raw water must be boiled
[or heated to at least 180ºF] promptly after it is
introduced into the boiler in order to drive off the
dissolved gases which might otherwise corrode the
boiler.
b. 	PURGE GAS PIPING OF AIR – Check Manual
Shut Off Valve(s) and Pilot Shut Off Valve(s) at
boiler to see that they are closed. Turn gas on
at meter. Disconnect Pilot Tubing at Pilot Shut
Off Valve(s), open Pilot Valve(s) until gas flows
from valve(s) KEEPING A CONSTANT CHECK
DURING THE PURGING. Close pilot valve(s)
and reconnect the pilot tubing. (In Canada, refer
to applicable Installation Codes for purging
procedure.)
c. 	 SINCE LIGHTING INSTRUCTIONS,
SHUTDOWN INSTRUCTIONS, AND CONTROL
SEQUENCE OF OPERATION VARY WITH
GAS CONTROL SYSTEM INSTALLED,
REFERENCE SHOULD NEXT BE MADE TO
THE APPLICABLE CONTROL SYSTEM:	
EI Control System - Page 46
EP Control System - Page 52
THERM Control System - Page 57
	

Check all electrical circuits and connections. Then
follow lighting instructions up to a point where the
boiler is ready to light.

2.	 BOILER AND SYSTEM CLEANING

INSTRUCTIONS FOR TROUBLE FREE
OPERATION

	

A qualified water treatment chemical specialist
should be consulted for recommendations regarding
appropriate chemical compounds and concentrations
which are compatible with local environmental
regulations.
A.	 Steam Boilers
1. 	Oil, greases & sediments which accumulate in a
new boiler and piping must be removed in order
to prevent an unsteady water line and carry over
of the water into the supply main above boiler.
Operate the boiler with steam in the entire system
for a few days allowing the condensate to return
to the boiler. If the condensate can temporarily be

wasted, operate boiler only for the length of time it
takes for condensate to run clear. If the latter cannot
be achieved or if the condensate is returned to the
boiler, boil out the boiler using the surface blowoff
connection. See Fig. 7.
a. 	Drain boiler until water is just visible in gauge
glass. Run temporary 1½” pipe line from the
surface blowoff connection to an open drain or
some other location where hot water may be
discharged safely. Do not install valve in this
line.
b. 	Add an appropriate amount of recommended boil
out compound.
c. 	Start burner and operate sufficiently to boil
the water without producing steam pressure.
Boil for about 5 hours. Open boiler feed pipe
sufficiently to permit a steady trickle of water
from the surface blowoff pipe. Continue this
slow boiling and trickle of overflow for several
hours until the water coming from the overflow
is clear.
d. 	Stop burner and drain boiler in a manner and to
a location that hot water can be discharged with
safety.
e. 	Refill boiler to normal water line. If water in
gauge glass does not appear to be clear, repeat
steps (a. through c.) and boil out the boiler for a
longer time.
2. 		Low pressure steam boilers such as the 5B series
should be maintained with appropriate water
treatment compounds. Add suitable water treatment
compounds as recommended by your qualified water
treatment company.
3. 	Remove temporary surface blowoff piping, plug
tapping and reinstall safety valve. Boil or bring
water temperature to 180ºF promptly in order to
drive off the dissolved gases in the fresh water.
4. 	If unsteady water line, foaming or priming persist,
install gate valve in Hartford Loop and drain valves
in return main and at boiler and proceed as follows:
a. 	Connect hoses from drain valves to floor drain. 	
Close gate valve in Hartford Loop and open
drain valve in return main. Fill boiler to normal
water level, turn on burner and operate boiler
at this water level for at least 30 minutes after
the condensate begins to run hot, then turn off
burner.
	 Close all radiator valves. Remove all supply
main air valves and plug the openings in supply
main.

43

SECTION IV - OPERATION (continued)
b. 	Draw about 5 gallons of hot water from
boiler into a container and dissolve into it the
appropriate amount of a recommended boilout
compound. Remove safety valve from boiler
and pour this solution into boiler, then reinstall
safety valve.
c. 	Turn on burner and keep operating while feeding
water to boiler slowly. This will raise water
level in boiler slowly into supply main and back
through return main, flowing from drain hose
at about 180ºF. Continue until water runs clear
from drain hose for at least 30 minutes.
d. 	Stop feeding water to boiler but continue
operating burner until excess water in boiler
flows out through supply main and water lowers
(by steaming) until it reaches normal level in
boiler.
	 Turn off burner. Drain boiler. Open all radiator
valves. Reinstall all supply main air valves.
Open gate valve in Hartford Loop.
e.	 When boiler has cooled down sufficiently
(crown-sheet of sections are not too hot to
touch), close the drain valves at boiler and in
return main and feed water slowly up to normal
level in boiler. Turn on burner and allow boiler
to steam for 10 minutes, then turn off burner.
Draw off one quart of water from bottom gauge
glass fitting and discard. Draw off another quart
sample and if this sample is not clear, repeat the
cycle of draining the boiler and return main and
refilling the boiler until sample is clear.
f. 	If the boiler water becomes dirty again at a later
date due to additional sediment loosened up in
the piping, close gate valve in Hartford Loop,
open drain valve in return main, turn on burner
and allow condensate to flow to drain until it has
run clear for at least 30 minutes while feeding
water to boiler so as to maintain normal water
level. Turn off burner, drain boiler, open gate
valve in Hartford Loop, then repeat step 1 above.
3. 	Make pH or Alkalinity Test
	 After boiler and system have been cleaned and
refilled as previously described, test the pH of
the water in the system. This can easily be done
by drawing a small sample of boiler water and
testing with Hydrion paper which is used in the

44

4. 	

same manner as litmus paper, except that it gives
specific readings. A color chart on the side of
the small hydrion dispenser gives the reading in
pH. Hydrion paper is inexpensive and obtainable
from any chemical supply house or through your
local druggist. The pH should be in accordance
to “Minimum Water Quality Requirements” chart
below. Add some washout chemicals (caustic soda),
if necessary, to bring the pH within the specified
range. With this lower level of protection, care must
be exercised to eliminate all of the free oxygen in
the system.
Boiler is now ready to be put into service.

Recommended Water Quality Requirements
pH: 8.3 - 10.5
TDS: < 3500 ppm
Total alkalinity ppm as CaCO3 : < 1200
Total copper ppm: < .05
Oily matter ppm: < -1

SECTION IV - OPERATION (continued)
4. EI CONTROL SYSTEM – The EI control system

utilizes a solid state ignition control which lights the
pilot burner by spark. Pilot gas is ignited and burns
during each running cycle (intermittent electric pilot).
Main burner and pilot gas are extinguished during the
“off” cycle.

	

This system permits the main gas valves
[Robertshaw7000 for 5006B thru 5009B, (2) V88A’s
for 5010B thru 5014B] to open, and the pilot line gas
valve to remain open, only when the Pilot Burner is
proven to be lit.

	

Should a loss of flame occur, the main valve closes
and the spark reoccurs within 0.8 second. The ignition
module has an internal 100% lockout function to
completely shutdown the system should the pilot gas
fail to ignite within approximately 90 seconds. Five to
six minutes after shutdown, the Ignition Module restarts
the ignition sequence. The ignition trial, shutdown, and
wait sequence continues until either the pilot lights or
the Thermostat is set below room temperature (to end
the call for heat). The ignition sequence can be reset by
setting down the Thermostat for one minute.
a. 		OPERATING INSTRUCTIONS
(1) Make sure all Manual Main Shut-off Valves and 	
all Pilot Valves have been off for at least five 	
minutes.
(2) Set Operating and Limit Controls to desired 	
settings.
(3) Turn all Manual Main Shut-Off Valves and Pilot 	
Valves to Open Position.
(4) Turn on Main Electric Switch and Service 	
Switch – Pilot(s) will automatically light main 	
burners.
b.	 NORMAL OPERATION SEQUENCE
5006B thru 5009B, see Fig. 40
5010B thru 5014B, see Fig. 41
5015B thru 5026B, see Fig. 42
c. 		SHUT DOWN INSTRUCTIONS
(1) Close manual shut-off valves and pilot valves.
(2) Turn off main electric switch.
d.	 SAFETY SHUTDOWN
(1) 	Safety Switch Circuit
		If limit control, low water cut-off or any other
electrical safety switch opens, power to the 24V
terminal of all S8610M Ignition Controls is
interrupted thus de-energizing terminals PV and
MV. Loss of power to these terminals means
loss of power to all pilot gas valves and to main

46

gas valves, respectively. Thus, pilot burner and
main burner flames are extinguished.
	 Normal operation can be resumed when the
cause of safety switch malfunction is corrected.
Any controls with Manual Reset must be
reactivated.
(2) Pilot Failure
	 Pilot failure can occur during the start-up or
during the operating cycle of the boiler. Any
failure of a Q3481B pilot will close the main
gas valves controlled by this pilot within 0.8
second. For 90 seconds after pilot failure, the
Ignition Control will try to reestablish pilot
flame. If the pilot flame cannot be sensed by
the sensing probe, the module will lock out
on safety. Five to six minutes after shutdown,
the IGNITION MODULE restarts the ignition
sequence. The ignition trial, shutdown, and wait
sequence continues until either the pilot lights
or the Thermostat is set below room temperature
(to end the call for heat). The ignition sequence
can be reset by setting down the Thermostat for
one minute.
	 On 15 section and larger boilers, where two
manifolds, gas trains and pilot systems are
employed, failure of one pilot will not affect
operation of the other system. Thus, it is
possible to fire the boiler at a reduced rate thru
one manifold while the other is inoperative.
	 Pilot failure is caused by one of the following:
(a) 	Pilot burns yellow resulting in weak signal
from sensor to Ignition Control – may be
due to dirt or lint that has covered the lower
portion of the pilot burner – remove with a
soft brush or by vacuuming.
(b) 	Loss of pilot gas – may be due to faulty
pilot solenoid valve, improper wiring, loose
connections, or low voltage.
(c) 	Loss of signal from sensing probe – may be
faulty probe, improper or loose electrical
connection, or faulty Ignition Control.

Be sure power is off when checking high voltage
connections.

SECTION IV - OPERATION (continued)
EI SEQUENCE OF OPERATION - 5006b Thru 5009b
When operating control closes, the electric spark and pilot valve are automatically
energized. The sensing probe proves the presence of the pilot flame. Internal switch
action de-energizes the spark and energizes the main gas valves starting main burner
operation. When the operating control is satisfied the pilot gas valve and the main gas
valves are de-energized stopping the burner operation.
In the event of excessive steam pressure (steam boiler) or excessive boiler water
temperature (water boiler), the high limit control will de-energize the pilot gas valve
and the main gas valves stopping burner operation.
The low water cut-off will also stop burner operation if the water level in the boiler
should drop below the lowest safe level.

SECTION IV - OPERATION (continued)
EI SEQUENCE OF OPERATION - 5010b thru 5014b
When operating control closes, the electric spark and pilot valve on each side are
automatically energized. The sensing probe on each of the pilots proves the presence
of the pilot flame. Internal switch action in each ignition module de-energizes the spark
and energizes the main gas valves for its respective gas train, starting main burner
operation. When the operating control is satisfied the pilot gas valve and main gas
valves for each gas train are de-energized stopping burner operation.
In the event of excessive steam pressure (steam boiler) or excessive water temperature
(water boiler) the high limit control will de-energize the pilot valves and main gas valves
on both sides stopping burner operation.
The low water cut-off will also stop burner operation if the water level in the boiler
should drop below the lowest safe level.
Should one of the pilot flames fail to ignite or become extinguished, the main gas valves
controlled by that particular pilot would close stopping burner operation on the
burners supplied by that gas train. Operation of the burners supplied by the second gas
train would be unaffected.

7.	 EP CONTROL SYSTEM – 5006B thru 5014B
	

	

The EP Control System utilizes an RM7890A Relay
Module and a Q179C Rectification Pilot, which in
addition to a pilot burner and rectifying flame rod flame
detector to prove pilot, includes an ignition electrode
for spark ignition of the pilot. A Webster 612-6A7
Transformer supplies the high voltage spark potential.
Once pilot flame continues as long as there is a “call for
heat” (intermittent electrically ignited pilot).
The RM7890A Relay Module Primary Control is a
non-programming amplifying relay which when used
with the Q179C Pilot provides solid state electronic
Flame Safeguard Protection that will not allow the main
gas valves to open on “call for heat” for that will shut
down main burners within 0.8 second if pilot flame is
not “proved”. Relay Module will lockout on safety
shutdown within 15 seconds if there is a pilot flame
failure on start or, if during the “run” cycle, pilot flame
is not re-established. Since #8 terminal in the Relay
Module is de-energized at end of safety switch timing, a
solenoid valve in the pilot line will close and thus 100%
shut-off is achieved.
a. 	OPERATING INSTRUCTIONS
(1) 	Make sure Manual Main Shut-off Valve and
all Pilot Valves have been off for at least five
minutes.
(2) 	Set Operating and Limit Controls to desired
settings.
(3) 	Turn Manual Main Shut-off Valve and Pilot
Valve to Open Position.
(4) 	Turn on Main Electric Switch and Service
Switch – Pilot will automatically light main
burners.
SEQUENCE OF OPERATION EP - See Fig. 44
b. 	NORMAL OPERATION - 5006B thru 5014B
(1) 	When the operating control calls for heat,
terminal #6 of RM7890A Relay is energized.
(2) 	A component check circuit in the RM7890A
Relay is activated which, checks the electronic
network in the relay.
(3) 	Terminals #8 and #10 of the relay are energized.
Terminal #8 opens pilot line solenoid valve
supplying gas to pilot. Terminal #10 energizes
ignition transformer creating electric spark
ignition at pilot.
(4) 	Flame rod circuit between Q179C pilot and
RM7890A proves presence of pilot flame
electronically.
(5) 	Terminal #10 to ignition transformer is deenergized.
(6) Terminal #9 is energized and supplies power to
the main gas valves.

52

(7) 	Main gas valves open and main burners are
lighted by pilot.
(8) 	When operating control is satisfied, terminals
#6 and #9 are de-energized. Main Gas Valves
and pilot line solenoid valve are all de-energized
and main burner and pilot burner flames are
extinguished.
c. 	SAFETY SHUTDOWN
(1) 	SAFETY SWITCH CIRCUIT
	
If limit control, low water cut-off or any other
electrical safety switch opens, power to terminal
#6 in relay is interrupted thus de-energized
terminal #9 and #8 in relay which de-energizes
main gas valves and pilot valves. Main gas
burners and pilot burners are immediately
extinguished. Normal operation can be resumed
when the cause of safety switch malfunction
is corrected. Make sure all manual resets are
activated where involved.
(2) 		PILOT FAILURE
(a) 	Pilot failure can occur during the start of
operating cycle of the boiler. Any pilot
failure, on the Q179C electronic pilot, after
ignition of pilot flame will close the main
gas valves in 0.8 second.
(b) 	For 15 seconds after failure of the Q179C
pilot, the relay through terminals #8 and #10
will try to establish pilot flame. If not pilot
flame can be sensed by the flame rod circuit,
terminal #8 and #10 are de-energized, and
the relay will lock out on safety.
(c) 	Pilot failure is caused by the following:
	(1) 	Complete loss of gas supply.
	(2) 	Poor ignition spark caused by low 	
	 voltage, poor ground connection, faulty 	
	 wiring, and possibly a defective ignition 	
	 transformer.
	(3) 	Low gas pressure will prevent flame rod 	
	circuit from sensing pilot flame properly.
	(4) 	Unusually strong secondary air drafts 	
	 can blow the pilot flame away from the 	
	 flame rod momentarily causing nuisance 	
	 shutdown.
	(5) 	A pilot line solenoid valve will not open 	
	 because of faulty wiring, low voltage, or 	
	 possibly the valve is defective.
(6) A defective RM7890A may be the cause	
	 but items (1) thru (5) should be followed 	
	 first. Refer also to RM7890A relay

8. 	 EP CONTROL SYSTEM – 5015B thru 5026B (see Fig.
	

45)
The 5015B thru 5026B boilers utilize two EP control
systems that are interconnected electrically thru all
operating and safety controls. Should any of the
aforementioned controls break the power supply circuit,
both EP control systems would be de-energized. The
succeeding paragraphs describe the function and
operation of each EP Control System. Should a pilot
failure on one EP Control System occur, the other EP
Control System would not be affected. Thus main
burners on the unaffected side would ignite on a “call
for heat” and would continue to operate until the

	

The EP Control System utilizes and RM7890A Relay
Module and a Q179C Rectification Pilot, which in
addition to a pilot burner and rectifying flame rod flame
detector to prove pilot, includes an ignition electrode
for spark ignition of the pilot. A Webster 612-6A7
Transformer supplies the high voltage spark potential.
Once pilot flame is proven, ignition stops but pilot
flame continues as long as there is a “call for heat”
(intermittent electrically ignited pilot).
The RM7890A Primary Control is a non-programming
amplifying relay which when used with the Q179C
Pilot provides solid state electronic Flame Safeguard
Protection that will not allow the main gas valve to
open on “call for heat” or that will shut down main
burners within 0.8 second if pilot flame is not “proved”.
Relay Module will lock out on safety shutdown within
15 seconds if there is a pilot flame failure on start or, if
during the “run” cycle, pilot flame is not re-established.
Since #8 terminal in the Relay Module is de-energized
at end of safety switch timing, a solenoid valve in the
pilot line will close and thus 100% shut-off is achieved.

SEQUENCE OF OPERATION EP – See Fig. 45
b.	 NORMAL OPERATION – 5015B thru 5026B
1. 	When the operating control calls for heat,
terminal #6 of each RM7890A is energized.
2. 	A component check circuit in each RM7890A is
activated which checks the electronic network of
the relay.
3. 	Terminals #8 and #10 of each RM7890A relay
are energized. Terminal #8 opens the pilot line
solenoid valve supplying gas to the Q179C pilot.
Terminal #10 energizes ignition transformer
creating electric spark ignition at the Q179C
pilot.
4. 	Flame rod circuit between each Q179C pilot and
terminal “11” on its respective RM7890A proves
presence of flame electronically at its Q179C
pilot.
5. 	Terminal #10 of each RM7890A and the ignition
transformer connected to it is de-energized.
6. 	Terminal #9 on each RM7890A is energized
supplying power to its respective main gas
valves.
7. 	Main gas valves open and main burners are
ignited by the pilot flames.
8. 	When the operating control is satisfied, terminals
6 and all other terminals on both RM7890A
relays are de-energized. The main gas valves
and pilot valve for each gas train are closed
and main burners and pilot burner flames are
extinguished.
c. 	SAFETY SHUTDOWN
(1) 	SAFETY SWITCH CIRCUIT
	 If limit control, low water cut-off or any other
electrical safety switch opens, power to terminal
6 and all other terminals on both RM7890A
relays are interrupted de-energizing the main
gas valves and pilot valves and the main gas
burners and pilot burners are immediately

56

extinguished. Normal operation can be resumed
when the cause of the safety switch malfunction
is corrected. Make sure all manual resets are
activated where applicable.
(2) 	PILOT FAILURE
(a) 	Pilot failure can occur during the start and
operating cycle of the boiler. Any pilot
failure on either of the Q179C Electronic
Pilots, after ignition of pilot flame will close
the pilot valve and the main gas valves
controlled by that particular RM7890A relay
in 0.8 second. The burners controlled by the
other RM7890A will continue to burn.
(b) 	For 15 seconds after failure of a Q179C
pilot, the relay through terminals #8 and #10
will attempt to re-establish pilot flame. If no
pilot flame can be sensed by the flame rod
circuit in 15 seconds, terminals #8 and #10
are de-energized, and the relay will lock out
on safety.
(c) 	Pilot failure is caused by the following:
(1) 	Complete loss of gas supply.
(2) 	Poor ignition spark caused by low
voltage, poor ground connection, faulty
wiring, and possibly a defective ignition
transformer.
(3) 	Low gas pressure will prevent flame rod
circuit from sensing pilot flame properly.
(4) 	Unusually strong secondary air drafts
can blow the pilot flame away from the
flame rod momentarily causing nuisance
shutdown.
(5) 	A pilot line solenoid valve will not open
because of faulty wiring, low voltage, or
possibly the valve is defective.
(6) A defective RM7890A may be the cause
but items (1) thru (5) should be followed
first. Refer also to RM7890A relay
literature furnished with the control.
(d) 	By referring to the Sequence of Operations
step by step operation of the system can
be controlled and the cause of pilot failure
can be readily found. After the cause of
pilot failure has been corrected, resume

9. 	 THERMOCOUPLE CONTROL SYSTEM (Canada 	
Only)

	

	

The 5006B thru 5014B boilers are equipped with
a Thermocouple Control System that utilizes a
constant-burning Q327A pilot, a Q309 thermocouple,
and a L62GB-3C Pilot Safety Switch. The Q309
thermocouple proves pilot flame and, in the absence
of such, will cool and, within 45 to 90 seconds, will
cause the L62GB-3C Pilot Safety Switch to which it is
connected, to break the electrical circuit to the main gas
valves as well as shut off the flow of gas to the pilot.
Thus, 100% shut-off is achieved.
The 5015B thru 5024B boilers utilize two
Thermocouple Control Systems that are interconnected
electrically thru all operating and safety controls.
Should any of the aforementioned controls break the
power supply circuit, both Thermocouple Control
Systems would be de-energized. The proceeding
paragraph describes the function and operation of each
Thermocouple Control System. Should a pilot failure
on one Thermocouple Control System occur, the other
Thermocouple Control System would not be affected.
Thus main burners on the unaffected side would ignite
on a “call for heat” and would continue to operate until
the operating control was satisfied.

a. 	LIGHTING INSTRUCTIONS
(1) 	Make sure that all main manual and pilot valves
have been off for at least five (5) minutes.
(2) 	Set operating and limit controls to desired
setting.
(3) 	Open pilot valve.
(4) 	Depress button on pilot safety switch to which
it is connected and hold lighted match on pilot.
Hold button in for at least one minute, or until
the pilot burner remains lit after the button is
released. Repeat for second pilot when boiler is
so equipped.

When operating control (A) calls for heat, it energizes main gas valves (B), starting burner operation.
The burners will operate until operating control (A) is satisfied. The high limit control (C), will stop burner
operation in case of excessive steam pressure (steam boiler) or excessive boiler water temperature (water boiler).
Low water cut-off (D) will stop burner operation if the water level in boiler drops below the lowest safe level.
The pilot safety switch (E), connected to main gas valve (B), prevents operation of the main burners in case the
pilot flame becomes extinguished. Pilot safety switch (E) provide for 100% shut-off of gas supply.

turned on, could blow liquid out of manometer.
(4)	 LP Gas Input
(a) 	Adjust Gas Train Regulator(s) so that manifold
pressure is ten (10) inches water column.
Turning Regulator Adjusting Screw Clockwise
increases pressure, Counterclockwise rotation
decreases pressure. If boiler is equipped with
two manifolds (5015B thru 5026B), pressure
in each must be equal.
(5)	 Natural Gas Input
(a) 	Approximate Input – Adjust Gas Train
Regulator(s) so that manifold pressure is three
and a half (3½) inches from water column.
Turning Regulator Adjusting Screw Clockwise
increases pressure, Counterclockwise rotation
decreases pressure. If boiler is equipped with
two manifolds, pressure in each must be equal.
If more accurate check on input is necessary,
see (b) below.
	 For minor input changes readjust Gas Train
Regulator(s) to increase or decrease manifold
pressure to obtain corresponding increase or
decrease in gas input. If it is necessary to
increase manifold pressure more than 0.3” of
water to obtain rated input, remove orifices
and drill one size larger. Reinstall and recheck
input rate.
(b) 	Additional Check on Input – Since input is
a function of heating value, specific gravity
and volume of gas flow contact your utility
for the first two items in order to utilize the
formula below. The gas meter should then be
clocked for three (3) minutes with stop watch

and substituting the appropriate values in the
formula below, determine what the gas flow
should be in this 3 minute period to give the
input shown on the Rating Plate:

(c)	 ADJUST AIR SHUTTERS – See Section V; 5.
	
Burners are normally shipped with the air
shutters in the wide open position. Loosen air
shutter securing screws and close air shutters
until yellow tips appear on flames, then open
shutters slowly until defined inner cones may
be seen. Lock shutters in this position.
(d)	 ADJUST BLEED LINE REGULATOR
(V88A’s)
	All gas boilers for the USA and Canada are
normally equipped with two diaphragm gas
valves per manifold. The gas valve(s) nearest
the manifold on all boilers, is equipped with an
adjustable bleed. This bleed regulator should
be adjusted so that the burners reach full fire
in approximately 10-12 seconds after the main
gas valves have been energized.
(e)	 ADJUST PILOT LINE PRESSURE – See 	
Section V - Service; 6. Pilot Flame
	Shut down boiler and remove gas valve and
manometer from 1/8” pipe tapping in each
manifold. Plug tappings with square head pipe
plugs. Install gas valve in tee in each pilot line.
Connect manometer to each gas valve and, with
boiler in operation, set pilot line pressure at
5.5” water – natural gas boilers and 6.5” water
– propane gas boilers.
	Shut boiler down, remove gas valves and
manometers and plug tees with square head
pipe plugs. Restart boiler.

SECTION IV - OPERATION (continued)
The following procedures should only be
performed by a qualified service technician.

11.	MINIMUM INPUT ADJUSTMENTS
	

This section covers Minimum Input Adjustments on
Honeywell V8944B Diaphragm Type “Lo-Hi-Lo” Gas
Valves, Honeywell V5055B Fluid Power Gas Valves
equipped with either a V4062A “Lo-Hi-Lo” Actuator or
a V9055A “Modulating” Actuator.
a. 	 Minimum Input Adjustments – “Lo-Hi-Lo”
Combination Valve, V8944B (Natural Gas Only)
	

On boilers equipped with the V8944B combination
diaphragm valve/regulator, Low Fire Adjustment
should not be less than Minimum Input shown on
Rating Plate (1/3 of full rated input). Fig. 48 shows
the outlet pressure adjustment screws for low and
high fire. The V8944B low and high fire pressure
settings are factory set at 0.8” and 3.5” W.C.
respectively. If further adjustments are necessary,
remove pressure regulator adjustment caps and
insert a screwdriver to raise or lower the regulator
pressure.

		Fig. 49 shows the Limit Switch Cam and Scales to
indicate direction to rotate cam for increasing or
decreasing low fire input on the Honeywell V4062A
“Lo-Hi-Lo” Actuator. To adjust the low fire setting
after the burners are “on”, the following procedure
should be used.
(1) With power to actuator “off”, remove the 	
wiring compartment cover.
(2) 	Check to be sure the low fire adjustment is set
at MAX to insure a safe light-off. (Low fire
adjustment is preset at factory in the MAX
position.)
(3) 	Disconnect the controller lead from terminal #4
on the actuator to keep the valve in the low fire
position.
(4) 	Start the system and establish the main burner
flame.
(5) 	Loosen the setscrew in the cam (Fig. 49) with
the special wrench taped to inside of actuator
cover. Keep the wrench seated in the setscrew. 	
Rotate the cam slightly downward (by moving
the wrench toward the base of actuator) to open
bleed valve. Actuator will start to close.
(6) 	When valve reaches desired low fire position,
quickly tighten setscrew and remove wrench. If
the desire low fire setting is “missed”, merely
loosen the setscrew and rotate cam in the
opposite direction to the desired set point.
(7) 	Shut down burner, and then restart. Repeat
several times to be sure the low fire setting
is that desired and suitable for correct burner
lightoff. Readjust if necessary.
(8) 	Disconnect power and reconnect controller lead
removed in step (3) above.
(9) 	Replace the wiring compartment cover.
c. 	MINIMUM INPUT ADJUSTMENTS –
MOTORIZED “MODULATING” ACTUATOR,
V9055A
		On boilers equipped with Fluid Power Valves that
have “Modulating” Actuators, Low Fire Adjustment
should not be less than Minimum Input shown on
Rating Plate (1/3 of full rated input).

Fig. 48
V8944B COMBINATION VALVE
b. 	MINIMUM INPUT ADJUSTMENTS –
	 “Lo-Hi-Lo” MOTORIZED ACTUATOR, V4062A
		On boilers equipped with Fluid Power Valves that
have “Lo-Hi-Lo” Actuator, Low Fire Adjustment
should not be less than Minimum Input shown on
Rating Plate (1/3 of full rated input).

		Fig. 50 shows the Low Fire Adjusting Screw for
increasing or decreasing low fire input on the
Honeywell V9055A “Modulating” Actuator. To
adjust the low fire setting after the burners are “on”,
the following procedure should be used.
(1) 	With power to actuator “off”, remove the wiring
compartment cover.
(2) 	Check to make sure the low fire adjustment is
set at MAX (full clockwise) to insure a safe
light-off. (Low fire adjustment is preset at the
factory in the MAX position.)

SECTION IV - OPERATION (continued)

Fig. 49
LOW FIRE ADJUSTMENT - V4062 ACTUATOR
(3) 	Remove the lead to V9055A terminal R.
Jumper terminal R to W. This will prevent the
actuator from going to the high fire position.
(4) 	Energize the system and light the main burner.
(5) 	Use a Phillips screwdriver, or standard type with
a blade no more than 3/16 inch wide, to turn
the low fire adjusting screw for the desired low
fire position. DO NOT PUSH INWARD ON
SCREW.
(6) 	Shut down the burner, and then restart. Repeat
several times to be sure the low fire setting is
that desired and suitable for correct burner light
off.
(7) 	Turn off power supply. Remove R-W jumper,
and reconnect the lead to terminal R on the
V9055A.
(8) 	Replace the wiring compartment cover.

12. MAIN BURNER FLAMES should have a clearly

defined inner cone, see Fig. 55 with no yellow tipping.
Orange-yellow streak caused by dust should not be
confused with true yellow tipping.

13. CHECK PILOT FLAME. Flame should be a blue

b. 	EI Pilot System
		Carefully remove ignitor sensor wire from ignition
module Main gas and pilot gas must shut off
immediately. If not, replace the module.

c. 	EP Pilot Systems
		Carefully remove the flame rod wire from terminal
“11” on the RM7890 Control. Main gas and pilot
gas must shut off. If not, replace the RM7890
Control.

17.	COMBUSTION CHAMBER BURN-OFF
a. 	The mineral wool combustion chamber panels
contain a cornstarch based binder that must be
burned out at installation to prevent odors during
subsequent boiler operation.
b. 	Ventilate the boiler room, set the high limit to its
maximum setting, set the thermostat to call for heat.
Allow the boiler to fire for at least an hour or until
the odor from the cornstarch has dissipated.
c. 	Return the high limit and thermostat to their desired
settings.

Avoid operating this boiler in an environment
where saw dust, loose insulation fibers, dry wall
dust, etc. are present. If boiler is operated under
these conditions, the burner interior and ports
must be cleaned and inspected daily to insure
proper operation.

63

If Burners must be removed, use the following
procedure:
a. 	Mark location on manifold of all burners with pilots.
b. 	Using a pair of pliers, remove hitch pin clips
(shaped like a hairpin) from groove in main burner
orifices. SAVE ALL CLIPS.
c. 	Remove all burners without pilots by lifting front
of burner slightly, then pushing burner toward rear
of boiler until front of burner clears orifice, then
lift rear of burner until head of weld pin on bottom
rear of burner clears keyhole slot in base rear
panel. Burner is now free and can be lifted out thru
opening in base front frame.
d. 	Remove all burners with pilots by first tracing all
electrical leads coming from pilot to their points of
connection, remove leads from terminals to which
they are connected, and then tag each lead with
respective terminal designation. Disconnect Pilot
Tubing at nearest connection to pilot and remove
burner as outlined in paragraph c. above.
e. 	When replacing burners, reverse procedure used in
removal of burners. Make sure burners are secure in
keyhole slots in base rear panel and hitch pin clips
are installed in grooves in all main burner orifices.
Burners with pilots must be in same locations as
original installation. If markings placed on manifold
(when burners were removed) are obliterated, see
Fig. 54. Reconnect electrical leads and reconnect
pilot tubing.
	 Reinstall Flue Cleanout Plates so that they are gas
tight. Reinstall Burner Access Panels and Jacket
Panels.

4. 	 LUBRICATION
	

Manufacturers Instruction should be followed on all
parts installed on the boiler that require lubrication.
Generally this involves only the circulator in a hot
water system. This includes:

Fig. 55
MAIN BURNER FLAME ADJUSTMENT

6. 	 PILOT FLAME –
	

	

Pilot Flame should be checked at initial start-up,
annually thereafter, or after flueway cleaning, or after
an extended shutdown period.
The EI Control System utilizes a Honeywell Q3481B
pilot. Flame should be adjusted by means of the pilot
line regulator 5.5” WC pilot line press so that a medium
hard center flame envelopes approximately 3/8” of
the end of the sensing probe, see Fig. 56. If flame
is yellow, primary air slot may be covered with dirt
or lint. This can be removed with a soft brush or by
vacuuming.
a. 	To adjust or check spark gap between electrode and
hood on Honeywell Q3481B intermittent pilot. (See
Fig. 56)
1. Use a round wire gauge to check spark gap.
2. Spark gap should be 0.1” for optimum
performance.

(a) Type of lubricant to be used
(b) Frequency of lubrication
(c) Points to lubricate

5. 	MAIN BURNER FLAMES –
	

	

70

Main Burner Flames should be checked at initial
start-up, annually thereafter, or after flueway cleaning,
or after an extended shutdown period. Main Burner
Flame should have a clearly defined inner cone, see
Fig. 55, with no yellow tipping. Orange-yellow streaks
caused by dust should not be confused with true yellow
tipping.
Yellow-tipping indicates a lack of primary air and
normally can be corrected by opening the air shutter.
Improper alignment of burner on orifice will also affect
primary air injection.

Fig. 56
PILOT FLAME - HONEYWELL Q3481B

SECTION V – SERVICE (continued)
	

The EP Control Systems utilize a Honeywell Q179C
Flame Rectification Pilot. Adjust pilot line regulator
(5.5” WC in pilot line) so that a medium hard center
flame envelops flame rod, see Fig. 57. If flame is
yellow, primary air opening may be covered with dirt
or lint. This can be removed with a soft brush or by
vacuuming.

	

The Thermocouple Control System utilizes a
Honeywell Q327A non-primary aerated pilot with a
Q309A thermocouple. Adjust pilot line regulator to
give a steady flame enveloping 3/8” to 1/2” of the tip of
the thermocouple, see Fig. 58.

7.	 LOW WATER Cut-off –
a.		Float Type Low Water Cut-off
		During the heating season, if an external low water
cut-off is on the boiler, the blow off valve should
be opened once a month (use greater frequency
where conditions warrant), to flush out the sediment
chamber so the device will be free to function
properly.
		Low-water fuel cut-offs and water feeders should
be dismantled annually by qualified personnel,
to the extent necessary to insure freedom from
obstructions and proper functioning of the
working parts. Inspect connecting lines to boiler

for accumulation of mud, scale, etc. and clean as
required. Examine all visible wiring for brittle or
warn insulation and make sure electrical contacts
are clean and that they function properly. Give
special attention to solder joints on bellows and float
when this type of control is used. Check float for
evidence of collapse and check mercury bulb (where
applicable) for mercury separation or discoloration.
Do not attempt to repair mechanisms in the field.
Complete replacement mechanisms, including
necessary gaskets and installation instructions, are
available from the manufacturer.

Before returning boiler to service:
Follow this low water cut-off check out procedure:
- 	 Set thermostat to the highest setting.
- 	 While boiler is operating, open drain valve
and slowly drain down boiler water.

71

SECTION V – SERVICE (continued)

Do not drain water below gauge glass.
- 	 Main burners should turn off when water
level drops below low water cut-off. At this
point the water level in gauge glass will just
be visible.
- 	 Be sure that it is the low water cut-off
control and not the room thermostat,
pressure cut-out or other control that has
shut off the burners.
- 	 Refill the boiler to the normal water level.
- 	 Main burners should reignite.
- 	 Clean out the boiler according to the
instructions for steam boilers on page 43.
- 	 Reset controls for normal operation.

8.	 FREQUENT WATER ADDITION	
	

A leaky system will increase the volume of make-up
water supplied to the boiler which can significantly
shorten the life of the boiler. Entrained in make-up
water are dissolved minerals and oxygen. When the
fresh, cool make-up water is heated in the boiler the
minerals fall out as sediment and the oxygen escapes
as a gas. Both can result in reduced boiler life. The
accumulation of sediment can eventually isolate
the water from contacting the cast iron. When this
happens the cast iron in that area gets extremely hot
and eventually cracks. The presence of free oxygen
in the boiler creates a corrosive atmosphere which, if
the concentration becomes high enough, can corrode
the cast iron through from the inside. Since neither of
these failure types are the result of a casting defect the
warranty does not apply. Clearly it is in everyone’s best

interest to prevent this type of failure. The maintenance
of system integrity is the best method to achieve this.
Refer to Recommended Water Quality Requirements
chart on Page 44.

9.	 OXYGEN CORROSION:
Oxygen contamination of the boiler water will cause
corrosion of iron and steel boiler components, and
can lead to boiler failure. Burnham Commercial’s
standard warranty does not cover problems caused
by oxygen contamination of boiler water or scale
(lime) build-up caused by frequent addition of
water.
There are many possible causes of oxygen
contamination such as:
a.	 Addition of excessive make-up water as a result
of system leaks.
b.	 Absorption through open tanks and fittings.
c.	 Oxygen permeable materials in the distribution
system.
	 In order to ensure long product life, oxygen
sources should be eliminated. This can be
accomplished by taking the following measures:
a.	 Repairing system leaks to eliminate the need for
addition of make-up water.
b.	 Eliminating open tanks from the system.
c.	 Eliminating and/or repairing fittings which allow
oxygen absorption.
d.	 Use of non-permeable materials in the
distribution system.
e.	 Isolating the boiler from the system water by
installing a heat exchanger.

If, during normal operation, it is necessary to add water to this boiler more frequently than once a month,
consult a qualified service technician to check your system for leaks. A leaky system will increase the
volume of make-up water supplied to the boiler which can significantly shorten a life of the boiler. Entrained
in make-up water are dissolved minerals and oxygen. When the fresh, cool make-up water is heated in the
boiler the minerals fall out as sediment and the oxygen escapes as a gas. Both can result in reduced boiler
life. The accumulation of sediment can eventually isolate the water from contacting the cast iron. When this
happens the cast iron in that area gets extremely hot and eventually cracks. The presence of free oxygen
in the boiler creates a corrosive atmosphere which, if the concentration becomes high enough, can corrode
the cast iron through from the inside. Since neither of these failure types are the result of a casting defect
the warranty does not apply. Clearly it is in everyone’s best interest to prevent this type of failure. The
maintenance of system integrity is the best method to achieve this.
