Install Top connections sized per Table 11.
a) Model LC-04 requires one riser off the Rear
Section. Plug the 4" tapping in the top of the
Front Section.

8.

9.

d) LCE models require three or more risers.

3.

4.

Size the Header per Table 11. Pipe the header at
least 24 inches above the normal boiler water line.
See Figure 19. This is required to prevent water from
carrying over into the header and then to the
system.
Figure 21 shows the Supply and Return piping for
Parallel Flow Gravity systems and all Pumped Return
Systems.

Counterflow Gravity systems require the boiler steam
line to enter the top of the steam main. See
Figure 20 for this special case.
Do not reduce the size or number of risers
shown. These are required for reliable operation of
the boiler. If the risers are undersized or incorrectly
placed, a sloped water line can occur in the boiler,
causing possible overheating of some sections.
Pipe the Header with an offset as shown in the
drawings. This offset prevents the expansion and
contraction of the Header from damaging the boiler
sections.

b) Models LC-05 through LC-10 require two risers,
one off the Front and one off the Rear Section.
c) Models LC-11 and LC-12 require three risers,
one each off the Front and Rear Sections plus
one off the Tapped Intermediate Section.

:1:1:1_,]]1[_-

Always locate the Steam Supply take-off
between the Equalizer and the last Boiler
Riser. (See Peerless Heater Company's "Steam
Installation Survey" for discussion). Locating the
steam supply between the risers will cause water
carryover to the system.
Do not use a bull head tee to provide steam supply
and equalizer connections, this will cause water level
bounce and carryover.

The use of a Hartford loop is recommended in all
installations. See Figure 19. The loop provides
additional reliability for the system.

Figure 22 shows typical piping for multiple boiler
Gravity Return systems. Figure 23 show typical
piping for multiple boiler Pumped Return Systems•

2.

Provide separate feed lines for multiple boiler
pumped return systems. Use either separate feed
pumps or solenoid or motorized valves to isolate
feeding of the boilers. This is needed to provide
reliable level control and avoid nuisance
performance problems.

3.

Condensate return units are not effective for multiple
boiler installations since they do not respond to the
needs of the boilers• always use Boiler Feed Units.

4.

Install a Float and Thermostatic trap at the boiler
water level on each of the mufltple boilers on a
pumped return system• This prevents flooding of idle
boilers due to condensation of steam•

Size the equalizer per Table 11. Models LC II, LC12 and LCE-13 through LCE 24 require two return
connections to the boiler off of the equalizer line.
Pipe the Hartford loop tee so the inside top of the
close nipple is 2 to 4 inches below the normal boiler
water line. See Figure 19.

Figure

On pumped return systems, install a boiler cock after
the pump to allow throttling of the pump discharge.
The pressure after the boiler cock should be no more
than 5 psig above the boiler operating pressure.
Pumping the water into the boiler too fast will cause
collapse of the water level and level control problems.

General Guidelines for Oil Piping
a) Follow the guidelines in the Burner Manual for
sizing oil lines. Never use smaller than I/2" OD
copper tubing.

Ground_

b) Install manual shut-off valves on the suction line
at the burner and at the oil line entrance to the
building. When installing a shut-off valve on the
return line, an oil pressure relief valve piped
ahead of the shut-off valve and discharged to the
tank must be provided to prevent over-pressure
conditions.

c)

Install a two-pipe oil distribution system when
possible. It will improve the reliability of the oil
delivery to the burner.

d)
e)

Use flare fittings when using copper tubing.

To Boiler Gas Control Train
Sediment Trap

Figure 27:

Provide an oil line filter in the suction line. Size
the filter for the suction gear capacity of the
burner oil pump if running a two-pipe system.
If burner is above the top of the fuel oil tank,
install a check valve on the oil suction line at the
burner to prevent oil from evacuating the line. If
burner is below the top of the tank, install an
anti-siphon device to prevent oil flow should the
oil line break.

The standard gas train is designed for a maximum
pressure of 1/2 psig (14 inches water column). Make
sure the system regulator will not allow a higher
pressure to the Gas Control Train under any
conditions.
The minimum gas supply pressure is listed on the
Burner Rating Plate. Make sure the system regulator
and the piping are sized and adjusted properly to
provide this pressure under all conditions.

to Boiler

Install a Service Valve, Sediment Trap and Ground
Joint Union at the supply connection to the Gas
Control Train as shown in Figure 27. These are not
supplied with the boiler. Install them in accordance
with local codes.

section or the side and top of the first intermediate
section.
2.

3.

4.

Do not apply piping which would raise or lower the
location of the cutoff relative to the tappings in the
boiler. Raising the water level over the design height
will cause water carryover to the system.
For correct location of typical low water cutoff/feeder
or low water cutoff/pump control, see Figures 31
through 34.
See Figure 29 for the location of control connection
tappings.

The boiler/burner must be electrically grounded in
accordance with the requirements of the authority
having jurisdiction, or in the absence of such
requirements, with the current edition of the National
Electrical Code, ANSI/NFPA Number 70.

2.

Use #14 gauge or heavier wire for supply wiring.
Protect the circuit with a fused disconnect switch (by
others) and a grounded neutral.

3.

Mount an electrical junction box on the boiler Front
Panel for connection of supply wiring and
distribution to the boiler controls.

4.

5.

Provide each float low water cutoff with a blowdown
valve. Pipe the blowdown away from traffic to a floor
drain if available. The blowdown valve is required
for proper maintenance of the control.

6.

Maintain a height of 461/2" from boiler foundation
the normal water level.

7.

When using Multiple Float Type Controls: Always
pipe the controls off of the same tappings to the
boiler. Do not mount on different ends of the boiler
or in different tappings. This can cause erratic
operation and nuisance problems with the controls.

Follow the instructions in the Burner Manual and the
Wiring Diagrams supplied with the burner and the

Gas Piping
a) Make sure the gas system piping and the
connections to the Boiler Gas Control Train(s)
have been leak tested.

Adjust the burner as needed for a CO 2 reading of:
a) Oil burners: CO 2 approximately 12.5% or I%
less than the level at which the smoke reading
goes above a trace on the Bacharach scale.
b) Gas burners: 9% to 10% with CO less than 50 ppm.

5.

b) After the boiler is in operation, check the
tightness of all joints in the boiler gas piping with
a soap suds solution.

Inspect al[ flue gas joints (sections, attachments,
breeching and vent) for gas tightness. Remove the
jacket panels in order to thoroughly inspect all rope
seal joints between the sections.

c) Purge the gas piping of all air up to the boiler
Gas Control Train.
3.

Oil Piping
a) Check the oil piping visually. Make sure all joints
are tight.
b) When the burner is firing, check the suction line
and return line pressures.
c) If the pressure exceeds the allowable pressure in
the Burner Manual or if the suction line vacuum
is higher than allowable, correct the piping as
needed to bring the suction line and return line
pressures within acceptable range.

On installations with high draft, do not leave the
boiler with a negative draft reading at the rear flue
box or draft damper. High negative draft can pull the
flame up into the boiler crown sheet and overheat the
iron.This can result in cracked sections or shortened
boiler life.

is parallel to the vent pipe (full open).

2.

Follow the instructions in the Burner Manual for
starting the burner, adjusting air openings and fuel
rates. Perform ignition system and flame supervisory
control test and checkout as described in the manual.

3.

After burner is set at rate, close the damper until the
pressure reading at the test opening in the rear flue box
or draft damper is between 0" wc and 0.1" wc positive.
See Table 15 for typical overfire pressure (measured at
the burner front plate) and boiler draft loss.

Follow additional instructions in the Burner Manual
for proving the burner component operation.
Check all controls to make sure they function
correctly.

Clean the boiler as described below no later than
one week after the initial start-up. Cleaning will be
more effective if the boiler operates a day or two to
loosen sediment and impurities in the system.

Cleaning the boiler requires the use of very hot water
and corrosive chemicals. Use care when handling to
prevent injury.

39

2.

3.

4.

5.

The boiler must be cleaned to remove any
accumulation of oil, grease, sludge, etc. that may be
in the system. These substances can cause foaming
and surging of the boiler water, producing unstable
water line and water carryover to the system.

9.

10. Continue skimming the boiler until the water flowing
from the skim tapping flows clear. This will take
some time, possibly several hours for a dirt_ system.

The piping for a 2" Skim Valve must be done as
shown in this manual, with the skim valve mounted
off the Pop Safety Valve tee on the rear of the boiler

11. After skimming is complete,
turn off the boiler.

Connect a 2 inch drain line off of the skim valve, run
to a point of safe discharge.

12. Close the make-up
blowdown valves.

Close all valves to the system. Provide a means of
continuous fresh water to the boiler for the cleaning

Open the skim valve. Fill the boiler until water begins
to flow out of the valve.

Table

15. Note: If the gauge glass becomes dirty again, this
indicates more contaminants have worked loose in
the system. Repeat the cleaning and skimming
process as needed to clean the system.

Turn burner on and allow the boiler water to heat up
to just below steaming (180 ° to 200 ° F). Cycle the
burner to maintain temperature during skimming. Do
not allow the boiler to steam. Steaming mixes up the
contaminants in the water instead of floating them at
the surface.

Do not leave the boiler unattended while firing.
Take great care not to allow the water level to drop
below the bottom of the gauge glass or to allow fresh
water make-up to flow in too fast.This will avoid the
possibility of causing the boiler sections to fracture.
