INSTALLATION
GENERAL
The PB150 hot water steel boilers are high quality pellet/corn fired heating units. The
installation of the unit shall be in accordance with the regulations of the authorities
having jurisdiction.
FREIGHT CLAIMS
All units should be inspected for damage upon arrival. Concealed damage claims
should, be filed immediately against the carrier by the consignee. The carrier is
responsible for taking prompt action on all claims.
SIZING
A complete heat loss calculation of the structure is necessary to choose the proper
size unit to install. The boiler should be sized to within 25% of the actual calculated
heat loss of the structure. Over sizing will result in short cycling and inefficient
operation. The PB150 boilers have large water content allowing for ample domestic
hot water.
Replacement boiler should not be sized from the firing rate of the old boiler. A DOE
sponsored study indicates 65% of the heating units in U.S. homes are substantially
oversized.
BOILER LOCATION
Boiler to be installed on a non-combustible heat resistant surface in a liquid
containment pan attached to a drain in a level position with clearances in accordance
with NFPA 31 Table 4-1 Form IL
STANDARD CLEARANCES Front 24” 610mm
Sides 6” 152mm
Rear 6” 152mm
Chimney Connector 18” 460mm
Reduced clearance installations shall comply with NFPA 31 Table 4-2
Appendix B.
To move the unit, push against the flue box or skids. Pushing or pulling the jacket or
burner will result in damage.
Be sure to level the unit by inserting shims under the base.
AIR FOR COMBUSTION AND VENTILATION
The unit must be installed where provision exists for combustion and ventilation air.
Ordinarily, provisions may be furnished by the following methods:
UTILITY ROOM
In buildings of tight construction, including most modern homes, you should provide
an opening, connecting to a well-ventilated attic, crawl space or directly with the
outdoors. The opening should have a minimum free area of 1 square inch per 1,000
BTU per hour of total input for all appliances in the enclosure and should terminate
below the burner level. Boilers installed in confined areas must have two ventilation

5
openings in the door. Each opening should have a free area of not less than 1 square
inch per 1,000 BTU (140 square inch per US GPH) of the total input for all appliances
in the enclosure. One opening located, near top of enclosure and one near the bottom.
BASEMENT
Where a boiler is installed in a full basement, infiltration is normally adequate to
provide air for combustion.
In buildings of tight construction where the basement windows are weather stripped,
one opening communicating with a well-ventilated attic or with the outdoors should be
provided. The opening should have a minimum free area of 1 square inch per 1,000
BTU per hour of total input for all appliances in the enclosure.
SPECIAL CONDITIONS
Where a boiler is located in an area where the operation of exhaust fans, kitchen
ventilation systems, clothes dryers, or fireplaces may create conditions of
unsatisfactory combustion or venting, special provisions should be made for additional
air for combustion, as specified by local authority.
TRIM ASSEMBLY
Install the drain valve in the 1-¼” tapping on the backside of the boiler. Install the
safety relief valve in the ¾” tapping on the backside of the boiler. The safety relief
valve should be piped to a place of safe discharge. Install your air bleed connection
into the 90° elbow mounted in the top ¾” tapping behind the smoke collector box.
Install the altitude gauge in the ¼” tapping provided on the front in the coil plate.
PACKAGED BOILER
Controls and burner are installed and pre-wired at the factory. Install Relief Valve as
noted in Trim Assembly.
BOILER PIPING
Minimum supply and return pipe size of not less than 1¼” to be used.
The recommended locations of pumps, expansion tanks, etc. are illustrated in Figures
2, 3, & 4. Relief valve discharge and drain valve piping should be piped to a safe place
of discharge. ALL plugs and water connections should be checked for leaks upon
installation and annually.
TANK-LESS WATER HEATING PIPING
The tank-less heater may be connected as shown in Figure 4. A mixing valve (not
supplied) may be used to reduce the water temperature at kitchen or bathroom taps.
When connecting to the domestic water coil a pressure temperature relief valve must
be installed.
High temperature water for a dishwasher may be obtained by piping as shown.
THE NUTS THAT SECURE THE TANKLESS COIL FLANGE SHOULD BE TIGHTENED
BEFORE THE BOILER IS FILLED WITH WATER, AFTER INITIAL FIRING AND EVERY
YEAR DURING ANNUAL MAINTENANCE. DETERIORATION DUE TO COIL GASKET LEAKS
SHALL VOID WARRANTY.

6
BURNER AND CONTROLS
Honeywell L6081A Aquastat Controller
This control is installed on the middle fitting of the domestic coil. These immersion
type controls are used with forced hydronic heating systems, which include domestic
water service. This model provides high limits, low limits for maintaining minimum
boiler water temperature and circulator controls. See the wiring diagram for proper
connections of this unit. The primary control is factory wired to the aquastat
controller. These controls working as a system will prevent the circulator operation if
the water temperature is below a predetermined low level. Likewise, if the water level
reaches a predetermined high limit the burner will automatically shut off.
Low Water Cut-off Switch RB-122
This control is installed in the supply tapping in the top front of the boiler. The RB-122
low water control is specifically designed to provide burner cut-off if there is an unsafe
water loss, which can result from a broken or leaking radiator or pipe, or a cracked
section in the boiler.
SEQUENCE OF OPERATION
Forced Circulation Hot Water System with Tank-less Heater
When the room temperature falls below thermostat setting, thermostat calls for heat
switching the control to full burn mode. When water temperature rises to the preset
temperature setting on the low limit – circulator control the circulator pump is turned
on providing hot water to room zone. At the same time the relay trips and reduces the
burner to pilot mode preventing over temperature. If the circulator pump turns off
because of low water temperature before the room thermostat is satisfied the relay
energizes and switches the burner back to full burn mode to increase the water
temperature. This cycling will continue until the room thermostat is satisfied. When
the room thermostat is satisfied the burner will switch back into pilot mode waiting for
the next heat demand. Because the burner stays in pilot mode between calls for heat,
in extended low demand periods the water temperature may rise enough to turn the
circulator pump on therefore a dump zone should be configured into the system.

PRIMARY CONTROL 0II350S
SEQUENCE OF OPERATION
3A 250V
When the wall thermostat circuit is closed, and calling for
heat, the light indicator will remain dim as long as the
circuit is closed. When the thermostat is open (not calling
for heat) the light will blink from bright to dim every 15
seconds as part of the counting procedure.
The computer board is protected by an AGC 3-amp fuse.
There are many manufacturers of this fuse. Fuses are
readily available at your local hardware or auto parts
store.

Power In
The On Time controls the amount of time the burner stays
active (fuel is fed). It operates in conjunction with the
cycle time and is pre-set in the control at 2 minutes
The PILOT CYCLE time switch controls the total cycle both
on and off, 8 or 16 minutes.
The On Time is subtracted by the Cycle Time Example:
With the On Time pre-set at 2 minutes and the Cycle Time
set at 16 minutes, the unit would come on (feed corn) for
2 minutes and not feed corn for 14 minutes. This gives
you a complete cycle time of 16 minutes.
The 0II350S primary control has 6 lead wires. A wiring
colour code is provided on back of each control. Black is
line power. White is neutral. Red is load and feeds the
auger motor and cup motor. Orange feeds the draft
inducer. 2 yellows go to the wall thermostat.
The POWER switch cuts power to burner but not blower
fan system and to shut the furnace down.
The PILOT DRAFT switch controls the speed of the draft
inducer on pilot or idle mode. Normally set on Medium,
but will vary with differing chimney configurations.

VENTING
Chimney required for the PB150 is 4” Class “L” (also known as PL
vent). A starting collar must be used to attach the venting system to
the furnace. When connecting into a Class “A” or masonry chimney a
listed 4” liner MUST
be used to prevent back drafting of the chimney.
EXISTING CLASS “A” CHIMNEY:
Run 4” Class “PL” connector from the furnace connection to a positive
connection with the class “A” chimney. A LISTED 4” STAINLESS STEEL
LINER MUST BE USED IN CLASS “A” CHIMNEYS. Make sure each
joint is firmly locked into place. Make sure the attachment of Class “PL”
to the Class “A” chimney is secure with sheet metal screws. Seal all joints
with high temperature silicone. Class “PL” connector should maintain a
pitch on rise from the furnace to the chimney of at least ¼” per foot.

VENTING
GENERAL-A PELLET/CORN FIRED UNIT SHALL BE CONNECTED TO A FLUE HAVING
SUFFICIENT DRAFT AT ALL TIMES TO ASSURE PROPER OPERATION.
1. Only a trained experienced serviceman should attempt the installation or
service of any boiler and or venting device. All venting installations must
comply with the recommendations of the venting manufacturer and with all
state and local codes. Only use listed PL type venting with an inside diameter of
4 inches. Warning, used chimney venting must be clean and in good condition.
2. All joints must be securely locked together, caulked with high temperature
silicone and fastened with at least 3 screws. This will prevent leakage and
future disassembly.
3. PL Vent must be supported from the structure by means of metal or other non-
combustible supports; horizontal pipes shall be supported at intervals not
exceeding 3 ft (1 m), exterior vertical pipes shall be supported at intervals not
exceeding 6ft (2 m).
4. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM
OF THIS UNIT; and DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVING ANOTHER APPLIANCE.
BOILER DAMPER CONTROLS
Damper operation
The damper is a plate that helps control the amount of airflow supplied for proper
combustion. With the damper pushed all the way in the airflow is at its minimum. As
the damper is pulled out, more air is allowed to flow.
It will be necessary to monitor the appearance of the flame during the first 4-8 bags
of fuel. If your flame is smoky red/orange with evidence of soot at the top of the
flame, you need more combustion air, pull the damper out ¼ inch and re-evaluate the
appearance of the flame. It may be necessary to repeat this process, moving the
damper ¼ inch at a time until proper combustion is attained (the flame should
become yellow and begin to “dance”). Tighten the damper lock down bolt and monitor
flame to maintain proper combustion.
Symptoms of insufficient combustion air include unburned fuel, lazy smoky
or red/orange flame, excessive ash or soot, excessive build-up on glass.
Symptom of excessive combustion air include fuel burns to quickly (smoking
or smouldering pellets), white to yellow flame.

12
WARNING ABOUT CHIMNEY FIRES
Failing to maintain your woodstove or fireplace properly can lead to a
chimney fire. Chimney fires occur when combustible deposits on the inner
walls of the chimney ignite. These combustible deposits, called "creosote,"
are a natural by-product of wood burning. A fire hazard exists if ¼” of
creosote (or more) coats the inner walls of the chimney.
Prevention:Chimney fires do not occur in clean, intact, properly installed chimneys.
Have a professional chimney sweep clean and inspect your appliance at least once a
year. More frequent cleanings may be required, based on the type of wood burned,
the type of appliance, and the frequency of use. In general, an older, uncertified
woodstove, or any appliance that is used frequently, will require more than one
cleaning per year.
Detection:The first indication of a chimney fire is usually the noise—a roaring sound
that grows louder as the fire’s intensity increases. Clouds of black smoke and sparks
will be seen exiting the top of the chimney; in severe fires, flames can extend several
feet above the chimney.
Action: In case of a chimney fire, follow these steps:
1. Call the fire department immediately.
2. Alert others in the house to evacuate.
3. Close the appliance’s dampers and/or the primary air inlet controls, limiting the
fire’s air supply and reducing its intensity.
4. Open the appliance door just enough to insert the nozzle of a 10 lb. dry
chemical fire extinguisher rated for Class ABC fires. Discharge the entire
content of the extinguisher into the appliance and shut the door.
5. If possible, wet down the roof and other outside combustibles to prevent fires
ignited by shooting sparks and flames.
6. Closely monitor all combustible surfaces near the chimney. During severe
chimney fires, these surfaces can become hot enough to ignite.
After a chimney fire, have the chimney inspected by a professional chimney sweep or
woodstove/fireplace installer; choose a professional who has earned credentials from
the National Chimney Sweep Guild at www.ncsg.org, Chimney Safety Institute at
www.csia.org or the Hearth Education Foundation at www.hearthed.com.
Contact your insurance carrier.
DO NOT USE THE CHIMNEY UNTIL A PROFESSIONAL HAS INSPECTED IT.
The excessive heat produced by a chimney fire can crack chimney walls, damage
chimney liners, and damage some types of factory-built chimneys. If not repaired,
these damages create a greater possibility for any subsequent chimney fire to spread
beyond the confines of the flue to the house.

DOMESTIC WATER COIL CONNECTION
When installing the domestic water coil connection an ASME certified pressure /
temperature relief valve must be installed. Install pressure temperature relief
valve in the hot water supply side exiting the domestic water coil, see figure 5. Drain
valve piping should be piped to a safe area for discharge. Failure to install pressure
temperature relief value will void boiler warranty.

WIRING INFORMATION
All internal electrical wiring is completed at the factory. All external wiring must
conform to the National Electric Code and any local codes. Line voltage leads utilize
wire nut connections.
A surge suppressor should be installed to protect control board.
Surge suppressors are available now that mount to your breaker box
providing protection to your whole house.
Refer to the wiring diagrams for all field wiring.
A. Field connections should be protected with a 15-amp fuse.
B. Install the room thermostat on an inside wall away from cold drafts,
windows, or heat from fireplaces, appliances, or sunlight. Set the heat
anticipator at .1 amps. Connect the thermostat leads to the yellow wires on
control board.
C. Install a separate fused disconnect switch near the unit so power can be
shut off for servicing.
D. Shut off service switch when the boiler is not in use for extended periods.
E. Failure to provide surge protection will void control board warranty.
WARRANTY
The limited warranty is not applicable unless these installation instructions are
followed.
HOMEOWNER INFORMATION
A. COMBUSTION AIR SUPPLY
Your burner requires an ample amount of clean combustion air in order, to
completely and efficiently burn its fuel. If an ample supply is not available
erratic operation, noise combustion, and fuel odours in the air may result.
REMEMBER THAT VENTING FANS OR A VENTER DRYER WILL GREATLY
INCREASE THE NEED FOR OUTSIDE AIR.
B. AREA AROUND THE BOILER
The area around the boiler should be kept clean and free or any combustible
materials, particularly oily rags or papers. The boiler should be accessible for
ease of service.
SERVICE INFORMATION
To avoid unnecessary expense and inconvenience, the boiler and burner, should be
inspected at least once a year by a qualified serviceman. If difficulty occurs, the
following should be observed before calling the serviceman:
A. Check to see if the thermostat setting is above room temperature
B. Check to see if the service switch is in the on position
DO NOT TAMPER WITH THE UNITS OR CONTROLS
POWER FAILURE
In case of power failure the combustion fan will stop and the fuel feeding motors will
stop feeding fuel to the fire pot. If this happens switch the primary control on/off
switch to DRAFT FAN. Should the power come back while the fire is smouldering the
emissions will be evacuated from the boiler, also this will prevent fuel from being fed
into the fire pot. When power is resumed and the fire is extinguished the boiler can be
safely restarted following the START-UP INSTRUCTIONS.

BURNING CORN IN THE PB150
1. The PB150 will burn most types of clean-shelled corn. It is not necessary to mix
the corn with wood pellets, although some people have had good success
burning a 50/50 mix. The PB150 boiler is supplied with a plug in the metering
cup. When burning corn leave this plug in to prevent over fuelling the boiler.
2. Typically burning corn requires a bit more combustion air than wood pellets.
The shutter on the draft inducer should be set at no less than 50% open, the
cycle time at 8 minutes, and the pilot draft switch on the primary control
medium.
3. The moisture content of the corn should be 15% or less, and care should be
taken to ensure that there are no foreign objects in the corn (i.e. sticks, stalks,
cob pieces) which will jam the feed system.
4. We recommend starting a corn fire with wood pellets as corn has a dense shell
that can be difficult to start. Note that corn has more BTU’s than wood pellets,
about 10,000 BTU’s per pound. Use gel starter to light unit.
WARNING
DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE.
DO NOT BURN GARBAGE, GASOLINE, NAPHTHA, ENGINE OIL OR OTHER
INAPPROPRIATE MATERIALS.
5. When burning corn, the primary combustion takes place on a fluidized bed at
the bottom of the fire pot. That’s why the corn pot has a slide bottom. The slide
bottom corn pot will need to be cleaned about once every 300 – 400 pounds of
corn (approx. 4 – 6 days). A white calcium-like deposit will be present in the
bottom of the fire pot. This deposit needs to be removed. We recommend
shutting off the unit by turning the on/off switch on the primary control to the
off position, letting the unit cool, and then pull the slide bottom completely out.
You may have to tap the top of the deposit to make it fall into the ash pan. We
would recommend purchasing an extra pot to make cleaning easier. Let
the pot cool completely to the touch and place into a bucket of water to
dissolve the clinker. DO NOT PLACE HOT POT IN WATER. You can also let
the pot sit in the air for 2-3 days then dump the residue out. DO NOT USE ANY
OBJECT TO POUND OUT THE CLINKER. THIS WILL DAMAGE YOUR POT. THERE
IS NO WARRANTY ON BURN POTS.
6. Place 1” of course oyster shell in the bottom of the pot before using. Under
heavy usage it may be necessary to remove the clinker daily. A bit of oyster
shell will be removed with the clinker. When all oyster shell has been removed,
remove pot for a thorough cleaning and replace with new pot, or clean and
replace oyster shell and pot.
