1. Ventilation of boiler room must be adequate

enough to provide sufficient air to properly support

combustion and venting.

2. When the boiler is located in an unconfined space

in a building of conventional construction frame,

masonry or metal, infiltration normally is adequate to

provide air for combustion and ventilation. However,

in any building which has been altered to conserve

energy or to minimize infiltration, the boiler area

should be considered as a confined space. If there is

anydoubt, install airsuppty provisions for combustion

and ventilation in accordance with section 5.3, Air for

Combustion and Ventilation, of the NFPA 54 1988

code, the recommendations that follow, or applicable

provisions of the local building codes.

3. When the boiler is installed in an unconfined

space, in a building of unusually tight construction,

air for combustion and room ventilation must be

obtained from outdoors or from spaces freely

communicating with the outdoors. A permanent

opening or openings having a total free area of not

less than 1 square inch per 5,000 BTU per hour of

total input rating of att appliances shall be provided.

Ducts may be used to convey make-up air from the

outdoors and shall have the same cross-sectional

area of the openings to which they are connected.

4. When air for combustion and room

ventilation is from inside buildings, the

confined space shall be provided with two

permanent openings, one starting 12 inches

from the top and one 12 inches from the

bottom of the enclosed space. Each opening

shall have a minimum free area of 1 square

inch per 1,000 BTU per hour of the total

input rating ofatl appliances in the enclosed

space, but must not be less than 100 square

inches. These openings must freely

communicate with the interior areas having

adequate infiltration from the outside.

and atl air is provided from the outdoors, the confined

space shall be provided with two permanent openings,

one commencing within 12 inches from the top and

one commencing 12 inches from the bottom of the

enclosure. The openings shall communicate directly,

or by ducts, with the outdoors or spaces (crawl or

attic) that freely communicate with the outdoors.

One of the following methods must be used to

provide adequate air for ventilation and combustion.

A. When directly communicating with the outdoors,

each opening shall have a minimum free area of

1 square inch per 4,000 BTU per hour of total

input rating of all equipment in the enclosure.

D. When ducts are used, they shall be of the same

cross sectional area as the free area of the area

of the openings to which they connect. The

minimum dimension of rectangular air ducts shall

not be less than 3 inches.

6. In calculating free area using louvers, grills or

screens for the above, consideration shall be given

to their blocking effect. Screens used shall not be

smaller than 1/4 inch mesh. If the free area through

a design of louver or grill is known, it should be used

in calculating the size opening required to provide

the free area specified. If the design and free area is

not known, it may be assumed that wood louvers wilt

have 20-25% free area and metal louvers and grills

will have 60-75% free area. Louvers and grills shall

be fixed in the open position or interlocked with the

boiler so that they are opened automatically during

boiler operation.

Inspect chimney to make certain it is constructed

according to the latest revision of the NFPA 211.

Local regulations may differ from this code and

should be checked. Where there is a conflict, the

local code will prevail.

The boiler must be installed into a chimney which

has a masonry or metallic chimney liner.

An unlined chimney wilt have leaks that wilt cause

poor chimney performance (no draft), and could

result in a positive pressure in the combustion

chamber.

Horizontal portions of the venting system should not

exceed 10 feet in length. Horizontal lengths over 10

ft. will have a negative effect on the chimney

performance.

The chimney should extend at least 2 ft. above any

portion of the building within 10 ft. (Figure 9) It should

produce a -.02 inch W.C. draft in the combustion

chamber. See "Chimney or Vent Sizes" chart for

recommended minimum and maximum chimney or

vent sizes.

Inadequate draft will cause improper combustion,

resulting in dirty flue ways and high fuel bills.

Connect flue pipe same size as boiler outlet to

chimney, sloping upward continuously toward the

chimney approximately 1/4" per foot. Bolt or screw

joints together to avoid sag.

If an oil fired water heater is vented into the same flue

as the boiler, provide a separate hole into the chimney

whenever possible. When this isn't possible, use a

"Y" connection in the flue pipe, using a separate draft

regulator for each unit. When a chimney will not

provide adequate draft to handle the input from the

water heater and boiler simultaneously, wire the

units so that only one wilt operate at a time, favoring

the water heater.

Oil tank and piping should be installed in accordance

with the National Board of Fire Underwriters and

local regulations. Oil storage tank, vent, fill pipe and

caps should be as prescribed by local codes. In no

case should the vent pipe be smaller than 1-1/4"

I.P.S. The fill pipe should not be less than 2" I.P.S.

The suction line from the tank to the burner should be

one continuous piece of tubing to prevent air enter-

ing the line. The suction line, must be 3/8" O.D.

copper tubing for runs of 50 feet or less, and 1/2"

O.D. for longer runs. An oil return line, same size as

the suction line, must be used on any installation

where the bottom of the tank is below the fuel unit of

the burner. Oil lines should be buried or otherwise

protected from mechanical injury. Flare fittings on all

oil lines are recommended. Compression fittings on

the suction line often allow air to be drawn into the

fuel pump, making it difficult to maintain oil pressure

at the nozzle. Do not run overhead fuel lines from

tank to oil burner.

Fuel pump connections and by-pass should be made

according to instructions attached to the fuel pump.

Electrical wiring must conform with the latest revi-

sions of the National Electrical Code, ANSI/NFPA

No. 70, and/or local authority having jurisdiction.

1. When an external electrical source is utilized,

the boiler, when installed, MUST BE electrically

grounded in accordance with these requirements.

2. Install a fused disconnect switch between

boiler and meter at a convenient location.

3. When the boiler is equipped with self-ener-

gized controls, no outside sou rce of electric power

shall be connected to the circuit of this system.

(See "Steam Wiring W/MM #67 Mechanical

LWCO" on next page.)

1. Thermostat should be installed on an inside wall

about four feet above the floor.

2. NEVER install a thermostat on an outside watt.

3. Do not install a thermostat where it will be affected

by drafts, hot or cold pipes, sunlight, lighting fixtures,

television, fireplaces, or chimneys.

4. Check thermostat operation by raising and lower-

ing thermostat as required to start and stop the

burner.

5. Instructions for the final adjustment of the thermo-

stat are packaged with the thermostat (adjusting

heating anticipator, calibration, etc.).

NOTE: Not all components listed are used in all control systems,

On a call for heat, the thermostat will actuate, com-

pleting the circuit to the boiler. In turn, the ignition

systems are activated and ignition wilt begin.

In the event of a low water condition, an automatic

low water cut-off device will interrupted power be-

tween the low water cut-off and the burner. The

burner will remain off until the low water condition is

corrected, (i.e., manually restore boiler water or

utilize a water feeder device which wilt automatically

restore water to its normal operating level).

IMPORTANT TO THE INSTALLER - Before putting

the boiler in operation, test the mechanical tow water

cut-off device for proper operation. While burner is

on, open the blow-off valve located in the lower

portion of the cut-off body. This will drain the water

quickly from the cut-off body and break the circuit to

the burner. If it does not, replace control.

The venting system should be inspected at the start

of each heating season. Check the vent pipe from

the boiler to the chimney for signs of deterioration by

rust or sagging joints. Repair if necessary.

Remove the vent pipe at the base of the chimney or

flue and, using a mirror, check for obstruction and

verify compliance to the latest revision of the NFPA

211.

The lever of the pressure relief valve (Figure 12) on

the boiler should be operated periodically to make

sure that it is functioning properly.

i t .......................

( .....

The pressure relief valve should open before the

steam pressure exceeds the 15 lb. reading on the

gauge. If this pressure is exceeded and the pressure

relief valve leaks steam when the boiler is operating

at normal pressures, it should be immediately

replaced. Corrosion can build up rapidly at the valve

seat and prevent its functioning as a safety device.

(See oil burner instructions for nozzle and electrode setting).

DO NOT SET FIRE VISUALLY.

Instruments are the only reliable method to

determine proper air adjustments. An

improperly adjusted burner causes soot and

high fuel bills because of incomplete

combustion of the fuel oil. This in turn may

req u ire excessive boiler maintenance, service

costs, and in some instances, house cleaning

or redecorating. A competent service

mechanic should be consulted to make the

proper adjustments with a smoke tester, CO 2

indicator, and draft gauge. NOTE: Bacharach

\0 r Dwyer test kits include these instruments;,

A. Check oil burner nozzle to make certain it is tight

in adapter. Burner mounting bolts should be tight.

B. Check electrode setting, as they may have been

jarred out of position during transportation.

C. Lubricate burner motor if necessary.

A 1/4" diameter slot is provided in the inspection cover plate to take draft readings in the combustion

chamber. (Figure 12) A 1/4" diameter hole will be required in the flue pipe between the boiler and barometric

damper (if used) to take draft, CO2, smoke and temperature readings. Adjust air shutter on oil burner to

obtain a "trace" of smoke. Measure CO 2at this point. Increase air adjustment to lower CO 2approximately

one percent. Check to insure minimum negative .02 w.c., (water column), "overfire" draft and zero smoke.

If -.02 w.c. "overfire" draft can not be maintained, changes and/or modifications may be required in the

venting or the chimney.

The following tables are provided as a guideline for initial start-up. Final adjustments MUST be made using

combustion instruments as previously mentioned.

IMPORTANT: Check safety control circuit after burner adjustments have been made for satisfactory performance, i)

A. Pressure Control- Remove cover and note pressure

setting. With boiler operating, decrease the setting.

When the setting is lower than boiler pressure, the

control will open and turn offthe boiler. After checking

pressure control, reset control to original setting.

B. Mechanical Low Water Cut-off- May be checked

by opening the blow-off valve on the lower portion of

the cut-off body while the boiler is running. This will

drain the water from the boiler and break the circuit

to the burner.

_ WARNING

2. Disconnect power cable at factory supplied burner

electrical disconnect. (Figure 12)

3. Loosen screws on the sides of the lower front

jacket panel. (Figure 6) Pull the bottom part of the

lower front panel forward and lift the lower front panel

up and off the boiler. (Figure 12)

4. Close oil valve (Figures 10-11) and disconnect oit

line from burner.

_MPORTANT: Do not swing door with oil line attached,../)

open

5. Remove nut from swing door stud on right hand

side of door.

Refill boiler to its normal water line.

C. Primary Control and Flame Sensor-

To Check:

1. Flame Failure - simulate by shutting off oil

supply with hand valve while burner is on. Sixty

seconds after flameout, the safety switch locks

out, ignition stops, motor stops and oil valve -

when used - closes. To restart, open oil supply

valve and reset safety switch.

2. Ignition Failure - With burner off, close oil supply

valve and run through start-up procedure, The

safety switch should lock out as in flame failure.

3. Power Failure - Turn off main power supply

switch while burner is operating. When burner

stops, restore power and burner should start. If

operation is not as described as above, check

wiring and controls.

It is recommended to replace the nozzle at the start

of each heating season. Lubricate the burner motor

and circulator motor- if required - with a few drops of

a good grade of light motor oil. Do not over oil. Have

a competent service person service the burner and

check the controls and check the electrodes for

carbon or cracks in the insulators. Burners should be

adjusted to produce the conditions shown in "Startup

and Adjustment of Off Burner."

Swing burner and door to the right until insulation

slightly compressed and the stud is exposed.

Attach nut to the stud and tighten it until the built

stop contacts the mounting door.

Reconnect oil line to burner.

Replace lower jacket panel, and tighten the screws.

5. Connect the power cable at the factory supplied

burner electrical disconnect.

6. Turn on power to boiler and bleed oil line.

1. Turn off power to boiler and allow boiter to coot down.

On steam boilers make certain the boiler is filled to

the water line as indicated in Figure 12. The gauge

cocks should be normally open. To remove dirt from

the gauge glass the petcock may be opened to flush

out the glass.

The radiator valves on a one-pipe steam system

must be either wide open or tightly shut. Do not

attempt to regulate room temperature by partially

closing the radiator valve.

Air vents on steam radiators and the supply main

release air from the system. If radiators do not heat

satisfactorily, make sure the air vents are clean and

operational.

The lever of the pressure relief valve on the boiler

(Figure 12) should be operated periodically to make

sure that it is functioning properly.

The venting system should be inspected at the start

of each heating season. Check the vent pipe from

the boiler to the chimney for signs of deterioration by

rust or sagging joints. Repair if necessary.

Impurities in boiterwater of a steam boiler may cause

foaming and an unsteady water line, or prevent

steam generation. They may result in objectionable

odors escaping from the vents on water boilers. This

condition is caused by oil, grease, and sediment

from pipe fittings collecting within the boiler and can

be remedied only by giving the boiler a thorough

cleaning.

BOILERS SHOULD BE CLEANED BY SKIMMING

OR BLOWING DOWN.

he boiler should not be left unattended dur

_,ing the cleaning process. 1

Some of the impurities in the boiter water will float on

the water and must be skimmed off.

With the boiler empty and cool, slowly begin to add

water. After water has entered boiler - never before

- turn "on" oil burner and adjust water flow so that the

water being added is kept just below boiling point.

Avoid boiling and turbulence.

The safety valve should open before the steam

pressure exceeds the 15 lb. reading on the gauge.

(Figure 12) If this pressure is exceeded and the

safety valve does not open, it must be replaced. Ifthe

safety valve leaks steam when the boiler is operating

at normal pressures, it should be immediately

replaced. Corrosion can build up rapidly at the valve

seat and prevent its functioning as a safety device.

If the water in a steam boiler appears to be dirty or

oily, or the water level in the gauge glass fluctuates

considerably, the boiler should be cleaned. A com-

petent service person will use approved cleaning

compounds and properly clean and flush out the

boiler. He/she should also clean or replace air vents

and traps, clean flue passages and check for proper

operation of all controls and safety devices.

Gradually raise hot water level to skimming hole

(Figure 6) installed on the rear section of the boiler

being careful not to raise it above the opening of the

hole. Skim until there are no impurities. Repeat the

process if necessary.

Water may be checked to make sure it is free from

oil by drawing off a sample at the skimming hole. If

the sample is reasonably free from oil, it will not froth

when boiled on stove. This test does not indicate the

amount of sediment which may lay in the bottom of

the boiler. It is therefore necessary that the boiler be

further cleaned by "blowing down."

Before blowing down the boiler, fill it to the water line.

Turn on burner and allow five pounds of steam

pressure to build up. Run a temporary connection

from one of the drain valves to a nearby sewer.

Connect to a drain valve on the opposite end of the

boiler from feed water inlet, if possible. Shut off the

oil burner, open drain valve and blow down the entire

contents of boiler.

Allow boiler to thoroughly cool and slowly refill to water

line. Repeat as many times as required until blow off

water is clear. Owner should blow down boiler at least

once each month dthe heating season.

If an exceptional amount of dirt or sludge seems to

be present in the boiler, a boiler cleaning compound

made by a reputable manufacturer may be used

according to the instructions of the manufacturer of

the compound. When any type of cleaning com-

pound is used, care must be taken to thoroughly

flush all traces of the compound out of the boiler.

Following blow down allow the boiler to coot. Add

fresh water slowly. Be certain to blow enough times

as required to remove compounds from system.

The area around the boiler must be kept clear and

free of combustible materials, gasoline and other

flammable vapors and liquids.

The free flow of combustion and ventilation air to the

boiler and boiler room must not be restricted or

blocked.

Periodic inspection and tightening of the tanktess

heater/cover plate bolts will reduce the risk of leaks.

See parts 3 and 5 under "Coil and Cover Plate

Replacement Parts."

Operation should be checked, with burner on, by

opening the blow-off valve located in the lower

portion of the low water cut-off body. This will drain

the water quickly from the cut-off body and break the

circuit to the burner. If it does not, replace the control.

During the heating season, the blow-off valve on the

low water cut-off should be opened once a week to

flush out the sediment chamber so the device will be

free to function properly. (Figure 12) Use a pail to

catch the discharge.

It is suggested that a qualified service agency be

employed to make an annual inspection of the boiler

and heating system. They are experienced in mak-

ing the inspections outlined above and, in the event

repairs or corrections are necessary, can make the

proper changes for safe operation of the boiler.
