WARNING

A. ACCESSIBILITY CLEARANCES
1. Clearances for service and from combustible surfaces
are the same for the LCE as for the LC. The
following recommendations allow for reasonable
access to the boiler. Follow local codes and
requirements when setting actual layout. See
Figure 1.1.
a) For installing, removing and servicing the burner:
provide 48" between the front of the boiler and
any adjacent wall or other appliance.
b) For access to the top of the boiler for cleaning
flueways: provide 24" above top of jacket.
c) For accessing and servicing of level controls and
inspection tappings (if used): provide 24"
minimum from the right side of the boiler to any
wall or obstruction.
d) For installation of jacket: provide at least 12"
from the left side of the boiler to any wall or
obstruction. More clearance may be needed for
longer boilers unless the jacket is pre-assembled
before placing the boiler.
e) For installation and removal of tankless heaters:
provide 45" between the end of the boiler and
any adjacent wall of obstruction. [This provides
for all available tankless coils. The spacing can
be closer for Heater Number X-1020 (allow 30")
or Heater Number X-1021 (allow 35")].
The equipment must be installed in accordance with installation requirements of the authority having
jurisdiction or, in the absence of such requirements, to the current edition of the
National Fuel Gas Code , ANSI
Z223.1/NFPA 54.
Where 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,
ASME CSD-1.
NOTICE
PREINSTALLATION
1. PREINSTALLATION
Carefully read these instructions before beginning work. Understand all aspects of the installation. Contact your PB Heat, LLC
sales representative or customer service for help in answering questions.
This boiler must be installed by a qualified contractor. The boiler warranty can be voided if the boiler is not installed, correctly.
Figure 1.1: Clearance Requirements
2

B. CLEARANCE FROM COMBUSTIBLE
CONSTRUCTION
Provide the following minimum clearances to
combustible construction. See Figure 1.1.
1. Sides: 6"
2. Rear of Jacket: 6"
3. Front of Jacket: 24"
4. Top of Jacket: 24"
5. Steam and Hot Water Pipes: 6"
6. Vent or Chimney Connector: 18"
C. COMBUSTION AND VENTILATION AIR
1. The installation must provide adequate air for
combustion and ventilation.
2. Unless the boiler room construction and natural air
infiltration are sure to provide all the air needed,
provide an opening or duct to the outside with a free
cross sectional area of at least 1 square inch per
4000 Btuh input for all installed appliances. At high
altitude, increase this requirement 4% for each 1000
feet above sea level.
3. The boiler room must never be under negative
pressure. If exhaust fans or other equipment can
cause a negative pressure in the boiler room, the air
openings and equipment design must be engineered
to assure a neutral or slightly positive pressure in the
boiler room at all times of operation. If the
equipment design and air openings cannot assure
this, then the boiler must be located in an isolated
room.
4. Using combustion air dampers:
a) If motorized dampers are used on the
combustion and ventilation air openings, wire
them such that they must open when the boiler
tries to operate. They must include a switch
which prevents the boiler from operating if they
do not open. See Figure 1.2.
D. CHIMNEY OR VENT
1. Inspect the existing chimney or vent system. Make
sure it is in good condition. Inspect chimney liner
and repair or replace if necessary.
2. The vent system and installation must be in
accordance with the current edition of the American
National Standard ANSI/NFPA 211, “Chimneys,
Fireplaces, Vents, and Solid Fuel Burning
Appliances”, or applicable provisions of the local
building codes. The venting requirements for the
LCE are the same as for the LC. Figure 1.3 shows
the top flue outlet required on LCE boilers.
3. Chimney/Vent Operation: The vent system must be
sized and installed to remove all combustion
products. If the vent system is not sized properly, the
burner may not operate properly. This can cause
poor combustion or sooting to occur.
4. If the vent terminates in an area where wind-
generated downdrafts are likely, install a suitable vent
cap which can control wind effects.
5. This boiler is designed to fire only with a pressurized
fire box. The breeching and vent may be sized for
negative, neutral or positive pressure (no more than
0.l inches water column at the boiler outlet) as
desired. But negative pressure overfire can cause
lifting of the flame and poor combustion or
overheating of the boiler crown sheet.
6. Forced draft breechings and vents must be sealed
and of heavy gauge steel construction and must
comply with all applicable codes of construction.
7. The vent diameter and minimum height for stub
vents are listed in the Ratings and Dimensions
Section of this manual. Always extend vent
terminations at least 3 feet above the roof line. See
Figure 1.3.

Failure to provide adequate venting can result in
severe property damage, personal injury or death.
WARNING

4
8. Exterior Vents:
a) Insulate sufficiently to ensure adequate draft and
to prevent vent damage due to condensation.
9. Vent Connection to Boiler:
a) Support the weight of the vent system
independently of the boiler flue connection.
b) Provide support of the vent connector
(breeching) at maximum 12 foot intervals to
prevent sagging and to provide a minimum
upward slope of 1/4" per foot.
10. Do not vent natural draft appliances in a combined
vent which operates under positive pressure.
11. Draft Regulator: Install a barometric draft regulator
where using high chimney or any high draft vent.
This is needed to prevent causing negative draft in
the boiler. Excess draft will cause flame lifting and
possible impingement.
12. The Draft Damper for the LCE boiler is a separate
piece, shipped in the Top Flue Outlet Carton.
a) Install the Draft Damper as close as possible to
the boiler flue outlet. It can be installed vertically
or horizontally provided that the connecting vent
piping and fittings are designed and installed for
pressurized service.
b) Secure the damper to the vent with screws and
seal the joints with a bead of high temperature
silicone sealant (found in Section Assembly Kits).
c) The vent must be installed so it can be
disconnected and the Top Flue Outlet removed
for proper cleaning of the flueways.
E. BOILER SETTING
1. If the boiler room floor is not level or if additional
structural support is needed, provide a good, level
foundation for the boiler with the minimum
dimensions given in Table 1.1. The flooring and
structural support system must be suitable for the
operating weight of the boiler and any connected
piping. Place the Steel Channels on the foundation
as shown in Figure 1.4.
2. Do not operate the boiler until the foundation, if new
concrete, has thoroughly cured. The concrete might
be damaged if heated too quickly due to the
entrained moisture remaining.
3. If the boiler is installed in a penthouse or if wiring of
any sort is run underneath the boiler foundation,
construct the foundation with provision for air flow
underneath between the main floor and the top of
the boiler foundation.
a) An acceptable foundation would be concrete
blocks laid with the openings lined up.
Do not install this boiler on carpeting or any
combustible flooring. A significant fire hazard could
result, with potential for property damage, personal
injury or death.
WARNING
Figure 1.4: Foundation Layout
PREINSTALLATION

b) If the foundation must be a concrete slab, use an
air cell high temperature insulating board, at least
1/2" inch thick, with aluminum backing, aluminum
side up. 1/2" inch thick high temperature
millboard with aluminum backing is acceptable
as well. Place the insulating board on the slab
between the steel channels.
F. INSTALLATION SURVEY
For new and existing installations, a Steam Installation
Survey is available from PB Heat, LLC. The survey will
provide information on how a steam boiler works with
your specific system and will provide an overview of
steam system operation in general.
You can also use this survey to locate system problems
which will have to be corrected. To obtain copies of the
Steam Installation Survey, contact your PB Heat
representative or download it from PeerlessBoilers.com.
G. PLANNING THE LAYOUT
Prepare sketches and notes of the layout to minimize the
possibility of interferences with new or existing
equipment, piping, venting and wiring.

A. PACKAGED BOILER
1. Remove crate top and sides. Remove any loose
cartons. Remove burner support pedestal and
nipple, if supplied
2. Lift boiler off crate pallet. Move to location
determined in Chapter 1: Preinstallation.
3. Remove lifting frame and hardware.
4. Re-install burner support pedestal and nipple if
necessary.
5. Proceed to Chapter 3: Piping the Boiler.
B. ASSEMBLED BLOCK BOILER
1. Move block to location determined in Chapter 1:
Preinstallation.
2. Remove lifting frame and hardware.
3. Proceed to Section D: Install Coils or Plates
C. KNOCKDOWN BOILER
1. Place channel rails as shown in Figure 1.4.
2. Open the Section Assembly Kit cartons. These
cartons contain the parts needed for assembly of the
sections.
3. Place the Back Section on the floor as shown in
Figure 2.1.
4. The Back Section combustion chamber area is lined
with a ceramic fiber blanket liner. Make sure the liner
is in good condition. Minor tears are not a problem,
but there should be no holes in the insulation.
PLACE THE BOILER
2. PLACE THE BOILER
Figure 2.1: Lay Sections on Floor and Apply Rope Seal and Gaskets

5. Clean the area around the flow ports and in the seal
recess. Use solvent and a clean cloth to thoroughly
clean all of the sealing surfaces. Remove all foreign
matter to assure a water tight seal when the sections
are drawn together.
6. Place a Flow Port Gasket in each of the three flow
port recesses as shown in Figures 2.1 and 2.2.
7. Apply rope adhesive or spray adhesive in the rope
groove around the perimeter of the section.
8. Place the sealing rope completely around the rope
groove, being careful not to stretch the rope. Extend
the rope from 1/4" to 1/2" past the end of the groove
on both sides of the cleanout opening on top of the
section. This will assure a gas tight seal when the
cleanout cover plate is applied.
9. Apply a bead of silicone sealant around each flow
port as shown in Figure 2.3. Do not get sealant on
the flow port gaskets.
10. Lift up the Rear Section and move into position on
the steel channels on the boiler foundation.
11. Screw a 3" pipe at least 30 inches long into the
lower 3" tapping on the back of the Rear Section as
shown in Figure 2.4. Place a block under the pipe as
shown in the figure and use as a brace during
assembly.
12. Place a Plain Intermediate Section on the floor and
prepare as above.
13. Carefully place the Intermediate Section against the
Rear Section and visually line up the flow ports as
close as possible.
14. Insert a tie rod with one nut and washer applied
into each of the four tie rod lugs. See Figures 2.5
and 2.6.
15. Place the nut and washer on the other end of the tie
rod and draw finger tight.
PLACE THE BOILER
Figure 2.3: Apply Silcone Sealant
Gaskets will be damaged by petroleum or its
derivatives. Completely remove all solvent residue
before placing gaskets.
Do not use petroleum based compounds in the
boiler.
CAUTION
Figure 2.2: Flow Port Machining & Gasket
The sections are heavy and must be supported
securely.

16. To properly assemble LC/LCE sections in the field,
the following steps must be followed to ensure that
no damage occurs to the tie rod lugs. A 0-100 ft-lbs
torque wrench is required.
a. Use a spirit level as shown in Figure 2.4 to check
the alignment of the sections as the nuts are
drawn up. Keep the sections plumb.
b. Draw the sections together evenly, in three
rotations. Torque each port to 20 ft-lbs for the
first rotation, then to 40 ft-lbs for the second
rotation, then to 60 ft-lbs for the third rotation.
Use the following sequence until all three ports
touch metal-to-metal at 60 ft-lbs. See Figure 2.7
for port reference.
i) First: Lower Top Port
ii) Second: Bottom Port
iii) Third: Upper Top Port
c. Tighten these (3) three locations only to a torque
value of 60 ft-lbs. DO NOT EXCEED.
d. After the three ports have been tightened to 60
ft-lbs, tighten the draw rod at the bumping pads
until metal-to-metal contact is reached. This will
assure a proper gas tight seal and prevent the
products of combustion from migrating into the
boiler room.
17. Repeat with the remaining sections.
a. Save the LWCO Intermediate with two 1"
tappings (for level control) for use as the section
closest to the front section.
b. Place the Intermediate Section with 3" top
tapping (Tapped Intermediate) in the position
given in Figure 2.9.
c. LCE ONLY. Save the (3) Top Flue Outlet
Intermediates (with wide opening in top of the
flue collector) for use as the sections closest to
the LWCO Intermediate Section. See Figure 2.9.
i) The sequence from Front to Rear is:
• Front Section
• 1" Low Water Cut-off Intermediate
• Three (3) Top Flue Outlet Intermediates
ii) The remaining intermediate sections are 3"
Tapped Intermediates or Plain Intermediates
as shown in Figure 2.8 and Figure 2.9.
Do not exceed the manufacturer’s torque
recommendations.

D. INSTALL COILS OR PLATES
1. Remove the coil cover plates, gaskets and mounting
hardware, located in the Flue Box Carton.
2. Place the cover plates and gaskets over any unused
heater openings. Place the cover plate with two 3/4"
NPT tappings on the upper flow port opening
(Position #2) of the Front Section.
3. Install tankless heaters, if used, in openings #1 and
#3. (Optional on Rear Section)
4. See Figure 2.10.
5. Steam boilers may have up to two coils installed
when supplied with special tankless coil rear seciton.
6. Standard Rear Sections do not have a tankless
opening (position #3). This is available only as
optional construction. This special rear section is
needed to install two coils on a steam boiler.
E. HYDROSTATIC TEST THE BOILER
1. Install a drain valve in the Rear Section, Tapping 13.
See Figure 8.2.
2. Provide a water supply line to the boiler.
3. Plug all open tappings in the boiler.
4. Provide a means to vent air as the boiler fills.
5. Fill the boiler with water, venting air as water level
rises.
6. Pressurize boiler to:
• 45 psig
• DO NOT EXCEED THESE PRESSURES.
a) Maintain pressure while checking all joints and
fittings for leaks.
7. After inspection is complete, drain the boiler and
remove plugs from tappings that are to be used.

Above heater ratings are based on intermittent demand for water from 40°F to 140°F with 200°F boiler water.
Steam boilers require a special rear section with coil opening in order to use two tankless heaters.
DANGER: Install mixing valve in hot water supply piping. Water temperature over 125°F can cause severe burns instantly or death from scalds.
