 IMPORTANT: Read this entire manual before installing
and operating this product. Failure to do so may result
in property damage, bodily injury, or even death. Proper
installation of this furnace is crucial for safe and efficient
operation.
 Contact your local building officials to obtain a permit
and information on any additional installation restrictions
or inspection requirements in your area.
 DO NOT throw this manual away. This manual has
important operation and maintenance instructions
that you will need at a later time. Always follow the
instructions in this manual.
 Never try to repair or replace any part of the furnace
unless instructions for doing so are given in this manual.
All other work should be done by a trained technician.
 Install appliance and venting at clearances specified in
this manual.
 DO NOT connect the pellet exhaust vent to a vent
serving any other appliance or furnace.
 DO NOT install a flue damper in the exhaust venting
system of this unit.
 Use of outside air is not required for this unit, but
is highly recommended. If installed into a tightly
constructed home, (Mobile Home) a fresh air opening of
at least 2 in. diameter (150mm) into the room where the
unit is installed is required. However return air make-up
is required for maximum heat distribution throughout
your home.
 This heater is designed and approved as a multi-fuel
(corn or wood pellets) furnace. Use only dried shelled
corn with a moisture content of 11% or less (which
provides the best results). Pellet fuel used should have
an ash content of 1% or less. If not, performance and
efficiency of the unit will suffer, and your warranty may
be voided.
Never use gasoline, gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or ’freshen
up’ a fire in this furnace. Keep all such liquids well away
from the furnace while it is in use.
 A working smoke detector must be installed in the same
room as this product.
 DO NOT unplug the furnace if you suspect a malfunction.
Turn the ON/OFF SWITCH to ”OFF’ and contact your
dealer.
Your furnace requires periodic maintenance and cleaning
(see ”MAINTENANCE ”). Failure to maintain your
furnace may lead to improper and/or unsafe operation.
 DANGER: Risk of Fire or Explosion - DO NOT BURN
GARBAGE, GASOLINE, NAPTHA, ENGINE OIL, OR
OTHER INAPPROPRIATE MATERIALS.
 Disconnect the power cord before performing any
maintenance! NOTE: Turning the ON/OFF Switch to
”OFF” does not disconnect all power to the electrical
components of the furnace.
 Allow the furnace to cool before performing any
maintenance or cleaning. Ashes must be disposed
of in a steel container with a tight fitting lid. The
closed container of ashes should be placed on a non-
combustible surface or on the ground, well away from
all combustible materials, pending final disposal.
 The exhaust system should be checked monthly during
the burning season for any build-up of soot or creosote.
Creosote in your exhaust can potentially cause a
chimney fire. In the event of a chimney fire, contact
your fire department immediately and press the “OFF”
button on your furnace. Have a clearly understood plan
to handle a chimney fire.
 CAUTION: Keep children away. Do not touch during
operation. Educate all children on the dangers of a
high-temperature furnace. Young children should be
supervised when they are in the same room as the
furnace.
 A power surge protector is recommended. This unit
must be plugged into a 110 - 120V, 60 Hz grounded
electrical outlet. Do not use an adapter plug or sever
the grounding plug. Do not route the electrical cord
underneath, in front of, or over the furnace. Do not
route the cord in foot traffic areas or pinch the cord
under furniture.
 The furnace will not operate during a power outage. If a
power outage does occur, check the furnace for smoke
spillage and open a window if any smoke spills into the

SAFETY AND EPA COMPLIANCE
Your Breckwell Furnace has been safety tested and listed to UL 391-2010, ASTM E1509-04, and CSA-B366.1-11, by
Intertek-Test Laboratories, Inc. Portland, Oregon USA. It is also exempt from EPA Phase II requirements.

FUEL CONSIDERATIONS
SHELLED CORN (DRY, PREFERABLY CORN WITH 11% OR LESS MOISTURE CONTENT)
• Optimum moisture content of corn should be 11% or less. Wet corn will rapidly deteriorate furnace components,
reduce efficiency and void all warranties. Purchase a moisture tester if in doubt.
• Corn must be clean and free from debris. Never burn corn right from the field. Damage caused by dirty corn is not
covered by the product warranty. Ask for clean filtered, bagged corn only. Stalk parts, excessive fines and cob
remnants will clog the auger.
• NEVER BURN SEED CORN IN YOUR FURNACE. Seed corn is treated with chemical pesticides that are harmful
or fatal if swallowed, therefore, seed corn is dangerous to have in the house, especially where children can reach it.
• Never burn “Deer Corn.” It frequently contains molasses/sugars.
• Store your corn supply in a dry place and keep bags or container sealed to prevent your corn from absorbing excess
moisture. Test the moisture content periodically to ensure proper dryness.
• There are many varieties of corn grown around the world. Each variety has unique characteristics including the
shape and size of the kernel. Your furnace will burn more consistently with a small to midsize kernel corn. If the
kernel size of the corn varies greatly or if you switch sources frequently, you will get a less consistent burn. There-
fore, purchasing corn from the same source will help achieve a more consistent burn. DO NOT USE CORN WITH
A HIGH WAX CONTENT!
• Oyster shell is highly recommended for best burn operations and to reduce clinker build-up
WOOD PELLETS
• As with corn, be consistent with your pellet supplier. Pellets will vary in content and burn characteristics from sup-
plier to supplier. A consistent supply of pellets will result in a more consistent and efficient burn.
• Check your pellets for foreign objects. Your furnace warranty will not cover damage done to your furnace due to
foreign objects in the fuel supply.
• Store your pellets in a dry place to prevent them from absorbing added moisture.
• To decrease sawdust buildup, the hopper will need to be vacuumed out after every 6-8 bags of pellets or more often
if the pellets are poor quality. You may have to screen-sift each bag of pellets if sawdust becomes a problem.
• Wood Pellets vary in size and ash content from less than 1% to 3% or more. Your furnace will burn more efficiently
with small to midsize pellets. Low ash content pellets will allow you to burn the furnace longer between cleanings.
Only wood pellets manufactured to the Pellet Fuel Industries (P.F.I.) standard for residential pellet fuels are recom-
mended. Performance will suffer if nonstandard pellets are used. Consult your local Breckwell reseller for more
information on approved wood pellet fuel.
• If fans are used in the fuel storage area, they should be installed so as not to create a negative pressure in the room
where your furnace is located.
CAUTION: DO NOT PLACE SUCH FUELS WITHIN THE SPACE HEATER’S INSTALLATION
CLEARANCES OR WITHIN THE SPACE REQUIRED FOR REFUELING AND ASH REMOVAL.
The top down method of fire building is recommended for this appliance. After making sure that the stove air intake
controls are fully open (completely pull-out towards you), Place the largest pieces of wood on the bottom, laid in paral-
lel and close together. Smaller pieces are placed in a second layer, crossways to the first. A third layer of still smaller
pieces is laid crossways to the second, this time with some spaces between. Then a fourth layer of loose, small kin-
dling and twisted newspaper sheets tops off the pile.
Higher efficiencies and lower emissions generally result when burning air dried seasoned hardwoods, as compared to
softwoods or to green or freshly cut hardwoods.
DO NOT BURN:
Burning these materials may result in release of toxic fumes or render the heater ineffective and cause smoke.
Dead wood lying on the forest floor should be considered wet, and requires full seasoning time. Standing dead wood
can usually be considered to be about 2/3 seasoned. Splitting and stacking wood before it is stored accelerates drying
time. Storing wood on an elevated surface from the ground and under a cover or covered area from rain or snow also
accelerates drying time. A good indicator if wood is ready to burn is to check the piece ends. If there are cracks radiat-
ing in all directions from the center then the wood should be dry enough to burn. If your wood sizzles in the fire, even
though the surface is dry, it may not be fully cured, and should be seasoned longer.

INSTALLATION OPTIONS
Read this entire manual before you install and use your Multi-Fuel Furnace. Failure to follow instructions
may result in property damage, bodily injury, or even death!
(See specific installation details for clearances and other installation requirements)
Certified for installation in a Residentail Type home in the USA and Canada. Also may be installed into a Manufactured
or Mobile Home.
As a Primary Furnace—the unit functions independently of any other system. The “Room Air” blowers will come on
when the plenum and exhaust temperatures reach a preset point programmed into the furnace’s circuit board (PCB). Unit
may also be used as a stand-alone shop heater. This is the only approved installation configuration in which ductwork
or return air is not required. All other configurations utilizing a ductwork system must supply return air to the appliance.
As a Secondary (Add-On) Furnace—the unit aids an existing gas/electric furnace helping cut down on operation time.
It is recommended that only a authorized technician install your Multi-Fuel Furnace, preferably an NFI certified specialist.

INSTALLATION
VENTING REQUIREMENTS
 Install vent at clearances specified by the vent manufacturer.
 Do not connect the pellet vent to a vent serving any other appliance or furnace.
 Do not install a flue damper in the exhaust venting system of this unit.
 INSPECT EXHAUST VENTING (joints, seals, etc.) REGULARLY TO ENSURE THAT SMOKE AND FLUE GASES
ARE NOT DRAWN INTO AND CIRCULATED BY THE AIR CIRCULATION SYSTEM.
The following installation guidelines must be followed to ensure conformity with both the safety listing of this furnace
and to local building codes.
MAXIMUM VENTING DISTANCE
Installation MUST include at least 3-feet of vertical pipe. This will create a natural draft to reduce the possibility of smoke
or odor escaping during appliance shutdown and keep exhaust from causing a nuisance or hazard by exposing people
or shrubs to high temperatures. The maximum recommend vertical venting height is 12-feet for 3-inch type “PL” vent.
Total length of horizontal vent must not exceed 4-feet (this does not include the clean-out tee). Use no more than 180
degrees of elbows (two 90-degree elbows, or two 45-degree and one 90-degree elbow, etc.) to maintain adequate draft.
PELLET VENT TYPE
A UL listed 3-inch or 4-inch type “PL” pellet vent exhaust system must be used for installation and attached to the pipe
connector provided on the back of the furnace (use a 3-inch to 4-inch adapter for 4-inch pipe). Use 4-inch vent if the
vent height is over 12-feet or if the installation is over 2,500 feet above sea level.
We recommend the use of Simpson Dura-Vent® or Metal-Fab® pipe (if you use other pipe, consult your local building
codes and/or building inspectors). Do not use Type-B Gas Vent pipe or galvanized pipe with this unit. The pellet vent
pipe is designed to be disassembled for cleaning and should be checked several times during the burning season. Pellet
vent pipe is not furnished with the unit and must be purchased separately.
PELLET VENT INSTALLATION
The installation must include a clean-out tee to enable collection of fly ash and to permit periodic cleaning of the exhaust
system. 90-degree elbows accumulate fly ash and soot thereby reducing exhaust flow and performance of the furnace.
Each elbow or tee reduces draft potential by 30% to 50%.
All joints in the vent system must be fastened by at least 3 screws, and all joints must be sealed with HI-TEMP RTV
silicone sealant to be airtight. The area where the vent pipe penetrates to the exterior of the home must be sealed with
silicone or other means to maintain the vapor barrier between the exterior and the interior of the home.
Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be
required.
PELLET VENT TERMINATION
Do not terminate the vent in an enclosed or semi-enclosed area, such as; carport, garage, attic, crawl space, under a
sun deck or porch, narrow walkway, or any other location that can build up a concentration of fumes.
The termination must exist above the outside air inlet elevation.
The termination must not be located where it could become plugged by snow or other materials.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your chimney
depends on the length of the chimney, local geography, nearby obstructions and other factors. Too much draft may
cause excessive temperatures in the appliance. Inadequate draft may cause backpuffing into the room and ‘plugging’
of the chimney. “Inadequate draft will cause the appliance to leak smoke into the room through appliance and chimney
connector joints.”
“An uncontrollable burn or excessive temperature indicates excessive draft.”
Take into account the chimney’s location to insure it is not too close to neighbors or in a valley which may cause unhealthy
or nuisance conditions.
IMPORTANT! This unit is equipped with a negative draft system that pulls through the burn pot and pushes the ex-
haust out of the dwelling. If this unit is connected to a flue system other than the way explained in this manual, it will not
function properly.

8
VENT TERMINATION CLEARANCES:
A) Minimum 4-foot (1.22m) clearance below or beside any door or window that opens.
B) Minimum 1-foot (0.3m) clearance above any door or window that opens.
C) Minimum 3-foot (0.91m) clearance from any adjacent building.
D) Minimum 7-foot (2.13m) clearance from any grade when adjacent to public walkways.
E) Minimum 2-foot (0.61m) clearance above any grass, plants, or other combustible materials.
F) Minimum 3-foot (0.91m) clearance from an forced air intake of any appliance.
G) Minimum 2-foot (0.61m) clearance below eves or overhang.
H) Minimum 1-foot (0.3m) clearance horizontally from combustible wall.
I) Must be a minimum of 3 foot (0.91m) above the roof and 2 foot (0.61m) above the highest point or the roof within
10 feet (3.05m).
VENT TERMINATION CLEARANCES
INSTALLATION

THROUGH THE WALL INSTALLATION (RECOMMENDED INSTALLATION)
To vent the unit through the wall, connect the pipe adapter to the exhaust motor adapter. If the exhaust adapter is at least
24-inches above ground level, a straight section of pellet vent pipe can be used through the wall.
Your furnace dealer should be able to provide you with an installation kit, which will include a wall thimble that will allow
the proper clearance through a combustible wall. Once outside the structure, a 3-inch clearance should be maintained
from the outside wall and a clean out tee should be placed on the pipe with a 90-degree turn away from the house. At
this point, a 3-foot (minimum) vertical section of pipe should be added with a horizontal cap, which would complete the
installation.
A support bracket should be placed just below the termination cap or one every 4-feet to make the system more stable.
If you live in an area that has heavy snowfall, it is recommended that the installation be taller than 3-feet to get above the
snowdrift line. This same installation can be used if your furnace is below ground level by simply adding the clean-out
section and vertical pipe inside until ground level is reached. With this installation you have to be aware of the snowdrift
line, dead grass, and leaves. We recommend a 3-foot minimum vertical rise on the inside or outside of the house.
The “through the wall” installation is the least expensive and simplest installation. Never terminate the end vent under a
deck, in an alcove, under a window, or between two windows. We recommend Simpson Dura-Vent®or Metal-Fab®kits.
THROUGH THE ROOF/CEILING INSTALLATION
When venting the furnace through the ceiling, the pipe is connected in the same manner as a wall installation, except
the clean-out tee is always on the inside of the house, and a 3-inch adapter is placed in front of the clean-out tee.
You must use proper ceiling support flanges and roof flashing (supplied by the pipe manufacturer; follow the pipe
manufacturer’s directions). It is important to note that if your vertical run of pipe is more than 15-feet, the pellet vent
pipe size should be increased to 4-inches in diameter.
Do not exceed more than 4-feet of pipe on a horizontal run and use as few elbows as possible. If an offset is required,
it is better to install 45-degree elbows rather than 90-degree elbows.

PRIMARY FURNACE
SECONDARY (ADD-ON) FURNACE
When installed as a secondary furnace, it may only be connected to the ductwork of the existing primary furnace (Gas,
Electric, etc.). It should not be wired in conjunction with the existing furnace’s circuitry. A Duct Damper must be installed
between the air discharge of the SP8500 furnace and the primary furnace. This duct damper prevents the air of the
primary furnace from back flowing to the secondary furnace. The damper must be a mechanical (spring return) style
with a simple closure switch to determine if the damper is opened or closed. The damper will connect to the SP8500’s
printed circuit board (PCB) as a signal connection only. See wiring diagram in this manual. The PCB will not supply
power to an electronic damper requiring a power supply. This power supply must come from a different source.
CAUTION: Do not connect your furnace’s ductwork to the cold air return duct of your existing furnace because a pos-
sibility exists of components of the central furnace overheating and causing it to operate other than intended. Only con-
nect to ductwork that is in good condition. Never direct the air flow from the exisiting furnace thru the Add-On furnace.
This appliance requires the installation of a cold air return duct system. The return air will provide a better distribution
of warm air throughout your home, making the unit much more efficient than if installed without a return system.

CONTROL PANEL
Turning the furnace OFF/ON, as well as adjustments for the fuel feed rate
and room fan speed are performed by pressing the appropriate button(s)
on the control panel which is located on the lower left-hand side of your
Breckwell furnace.
This unit can operate in either automatic or manual mode. Automatic mode
has pre-set default settings.
Pressing the “ON” button on the control panel will begin the start-up sequence
for the furnace. Fuel will begin to feed through the auger feed system
after 3 minutes. Pressing and holding the “ON” button will rotate the auger
continuously until button is released, which feeds additional fuel.
Pressing the “OFF” button on the control panel will cause the furnace to enter
its shut-down sequence. The fuel feed system will stop pulling fuel from the
hopper and, once the fire goes out and the furnace cools down, the fans will
stop running.
Pressing the “Heat Range” arrows, up or down, will adjust the amount of fuel
being delivered to the burnpot.
This unit comes preset from the factory to burn shelled corn. The display
will show a “Cr” in front of the heat setting. If burning only wood pellets, this
setting must be changed. To change, press and hold the heat range up and
down buttons simultaneously for approximately 2-3 seconds. The display
will change from “Cr” to “Pr”. If burning a pellet(50%) and corn(50%) mix,
the “Cr” setting will work the best for optimum performance.
The draft fan (exhaust) will come on as soon as the “ON” button is pressed. The fan will automatically adjust its speed
in accordance to the heat range setting. However, this speed can be manually operated by pressing the “Draft Fan”
arrows up or down. “Draft Fan” when pressed, the display will show “Df-A”, which is automatic. Press the arrows again
to adjust fan speed. When the furnace is in the manual mode, the optional thermostat will not properly control the unit.
When adjusting the Draft Fan setting, try only 1 setting above or below the heat setting.
The room fan(s) will come on once the unit has reached operating temperature. The room fans will automatically adjust
their speed in accordance with the heat range setting. By pressing the “Room Fan” buttons, the display will show “Rf-A”
which is automatic or how many fans are running.
The “Aux” button is for Agitator operation. When the unit is “OFF”, pressing the “Aux” arrows will rotate the agitator for
easy removal for cleaning. The agitator, when in Automatic mode, will operate at set intervals. However, these can
be changed by pressing the arrows on the “Aux” button. The agitator can be adjusted from 0 to 9, setting “0” is off and
setting “9” is high.
The “Auger Delay” button can be used to pause rotation of the Auger and Agitator for approx. 1 minute. This can be
cancelled by pressing the “ON” button.
The “Mode” button is used to switch between manual and automatic mode. When in auto mode, the fans, auger, and
agitator will operate at preset intervals unless changed manually using the buttons mentioned above. When in manual
mode, the draft fan (exhaust) will operate at full speed (100%), so the air must be controlled with the damper just below
the viewing door.
During normal operation, this unit constantly monitors itself for potential problems. In the event of an error condition, the
unit will stop and an error code will be shown in the display. See the list of error codes found at the end of this manual.

OPERATION
DAILY OPERATION
The hopper and furnace top will be hot during operation; therefore, you should always use some type of
hand protection when refueling your furnace.
Never place your hand near the auger while the furnace is in operation.
In the event of a power outage, the furnace will not function. It is very important that unit be vented properly, as the
natural draft is needed to clear the smoke from the furnace during a power outage. In case of power outage, remove any
installed air filters from the duct system. This will help circulate air through your system and not overheat the appliance.
If the unit was “ON” when the power outage occurred, one of the following will take place when power is restored:
1. If the furnace is still warm, it will resume feeding fuel and continue to operate normally. If the fire has gone out, you
will have to press the “OFF” button and then the “ON” button again to begin a new start-up sequence.
2. If the furnace has cooled-off, it will reset to its “OFF” condition. At this point, you may press the “ON” button to
begin a new start-up sequence.
NOTE: The unit will also shut down in the event of an draft fan failure; if this is the case, the unit will not re-start and you
must contact Customer Service at [phone].
SAFETY AND CONVENIENCE FEATURES
Your BRECKWELL incorporates a safety pressure switch that helps ensure proper operating conditions before feeding
fuel to the burn pot. Because the furnace works using an induced draft pressure, the furnace will not continue to operate
if the viewing door is left open, if the draft fan fails or if the exhaust system is blocked.
The temperature limit control will prevent your furnace from operating at abnormally high temperatures. Should the furnace
temperature begin to approach the factory pre-set limit, the temperature limit control will automatically slow down the
auger feed rate until the temperature returns to a normal condition. Both room air fans will also operate at full speed
until the furnace returns to normal operating temperatures.
If your furnace continues to cut back because it is reaching the temperature limits, reduce the “heat setting” to the next
lower setting.
TAMPER WARNING
This wood heater has a manufacturer-set minimum low burn rate that must not be altered. It is against federal regulations to
alter this setting or otherwise operate this wood heater in a manner inconsistent with operating instructions in this manual.
VISIBLE SMOKE
The amount of visible smoke being produced can be an effective method of determining how efficiently the combustion
process is taking place at the given settings. Visible smoke consist of unburned fuel and moisture leaving your stove.
Learn to adjust the air settings of your specific unit to produce the smallest amount of visible smoke. Wood that has not
been seasoned properly and has a high wood moisture content will produce excess visible smoke and burn poorly. Use
the included moisture meter to insure your wood has a 20% or less moisture content.
EFFICIENCY
Efficiencies can be based on either the lower heating value (LHV) or the higher heating value (HHV) of the fuel. The lower
heating value is when water leaves the combustion process as a vapor, in the case of woodstoves the moisture in the
wood being burned leaves the stove as a vapor. The higher heating value is when water leaves the combustion process
completely condensed. In the case of woodstoves this would assume the exhaust gases are room temperature when
leaving the system, and therefore calculations using this heating value consider the heat going up the chimney as lost
energy. Therefore, efficiency calculated using the lower heating value of wood will be higher than efficiency calculated
using the higher heating value. In the United States all woodstove efficiencies should be calculated using the higher
heating value.
The best way to achieve optimum efficiencies is to learn the burn characteristic of you appliance and burn well-
seasoned wood. Higher burn rates are not always the best heating burn rates; after a good fire is established a lower
burn rate may be a better option for efficient heating. A lower burn rate slows the flow of usable heat out of the home
through the chimney, and it also consumes less wood.

OPERATION
OPERATIONAL TIPS
Operational Tips for Good, Efficient, and Clean Combustion
• Get the appliance hot and establish a good coal bed before adjusting to a low burn rate (this may take 30 minutes
or more depending on your wood)
• Use smaller pieces of wood during start-up and a high burn rate to increase the stove temperature
• Be considerate of the environment and only burn dry wood
• Burn small, intense fires instead of large, slow burning fires when possible
• Learn your appliance’s operating characteristics to obtain optimum performance
• Burning unseasoned wet wood only hurts your stoves efficiency and leads to accelerated creosote buildup in your
chimney
OVER FIRING
Attempts to achieve heat output rates that exceed heater design specifications can result in permanent damage to the
heater
ASH REMOVAL AND DISPOSAL
Whenever ashes get 3 to 4 inches deep in your firebox or ash pan, and when the fire has burned down and cooled, remove
excess ashes. Leave an ash bed approximately 1 inch deep on the firebox bottom to help maintain a hot charcoal bed.
Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a
noncombustible floor or on the ground, away from all combustible materials, pending final disposal. The ashes should
be retained in the closed container until all cinders have thoroughly cooled.
SMOKE AND CO MONITORS
Burning wood naturally produces smoke and carbon monoxide(CO) emissions. CO is a poisonous gas when exposed
to elevated concentrations for extended periods of time. While the modern combustion systems in heaters drastically
reduce the amount of CO emitted out the chimney, exposure to the gases in closed or confined areas can be dangerous.
Make sure you stove gaskets and chimney joints are in good working order and sealing properly to ensure unintended
exposure. It is recommended that you use both smoke and CO monitors in areas having the potential to generate CO.

15
CAUTION: DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE
HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT
MAY CAUSE SKIN BURNS.
Before lighting your heater for the first time, make sure that all items are out of the hopper, ash pan and firebox
area. Press the “On” button and allow your heater to run for at least 4 minutes, to check for proper operation. Once your
heater is started, you will notice that the draft fan starts immediately. If you press the “Heat Setting” button up, you will
increase the heat setting as well as the draft fan speed. After 3 minutes, the auger and agitator will start rotating. Note:
The room fans will not operate until your furnace reaches preset operating temperatures. If proper operation of your
heater is confirmed, you can add fuel to the hopper and allow the auger to purge the fuel to the firepot.
• Turn the Heater to the “OFF” position and place a small handful of wood pellets or fire starting pellets (Pellets that
already contain fire starter) in the firepot.
NOTE: Even if you are burning corn or other fuels in your unit, wood pellets make an excellent source of starter
fuel. Corn can be very difficult to properly ignite.
• Squirt only a small amount of fire starter gel on top of the wood pellets (NOT necessary if using fire starting pellets).
• Light the fire starter and wait approx. 1-minute for it to start actively burning.
• Press the “On” button, adjust the heat range to read “Cr-3” or “Pr-3” depending on fuel setting. Pull the damper out
approximately 1 inch. This will automatically match your feed rate with the proper combustion air. As you increase the
heat setting, your feed rate and combustion air increase together. Once the unit reaches operating temperature, you
may reduce the heat setting.
• Three minutes after turning the stove “On”, the auger will begin feeding fuel into the firepot along with the agitator
turning. You should have the starting fuel completely burning in the firepot as the agitator rotates. NOTE: If the starting
fuel is not burning hot enough, you may see the fire begin to go out as new fuel is being added. If this occurs, pressing
the “Auger Delay” button will allow the auger to pause for 1 minute. Pressing the “ON” button will resume the auger
if 1 min. is too long. If not enough fuel is the reason for not burning, pressing and holding the “ON” button will allow
the auger to run continuously until you release the button.
• Once the fuel starts burning aggressively, you can adjust the heat setting to your desired range. Make sure that you
pull the damper out approximately 1 inch. It may need to be pulled out more for higher heat settings. Try opening a
1/4 inch at a time.
• As you begin to have better understanding of how the heater operates and the amount of heat you require, you can
adjust the heat settings up or down to your satisfaction.
• Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or
“freshen up” a fire in this heater. Keep all such liquids well away from the heater while it is in use.
• Overfire Protection - If the heater is being overfired, (burned too hot), the heater will automatically shutdown to avoid
damage to components in the heater. Refer to “Lighting Instructions” for proper use.
SHUT-DOWN PROCEDURE
Press the “OFF” button on the control panel to put the furnace in shut down mode. At this time, the red light above the
“OFF” button will illuminate. Once this is done, the auger will stop feeding fuel, but the room air fan(s) and draft fan will
continue to operate. When the internal temperature of the unit drops below the factory preset temperatures, the room
air fans and draft fan will cease to operate. The red light will then shut off and the unit will be completely shut down.
Never shut down this unit by unplugging it from the power source. Doing so can cause damage to the appliance or cause
a fire. The hotter the unit is during its operation, the longer it will take for the furnace to complete the shut down cycle.
If the furnace stays on for more than 2 hours after pressing the “OFF” button and you are 100% sure that the fire is
out, the furnace can be unplugged from the outlet. After approximately 10 seconds, the unit can be re-connected to the
power source and the control board will be reset.
WARNING: Never shut down this unit by unplugging it from the power source.
START-UP PROCEDURE
LIGHTING INSTRUCTIONS

16
 Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.
 Unplug your stove’s electrical cord prior to removing the back panel or opening the exhaust system for any
inspection, cleaning, or maintenance work.
 Never perform any inspections, cleaning, or maintenance on a hot furnace.
 Do not operate furnace with broken glass , leakage of flue gas may result.
 Establish a routine for the storage of fuel, care of the appliance, and firing techniques.
 Check daily for creosote buildup until experience shows how often cleaning is necessary.
EXHAUST SYSTEM
The by products of combustion contain small particles of fly ash. Fly ash will collect in the exhaust venting system
and restrict the flow of flue gases. Incomplete combustion during startup, shutdown, and/or incorrect operation of the
furnace can lead to soot formation which will collect in the exhaust system. Therefore, it is important that the exhaust
system be inspected and cleaned at least monthly during the burning season. Be aware that the hotter the fire, the
less creosote is deposited, and that weekly cleaning can be necessary in mild weather, even though monthly cleanings
can be enough in the coldest months.
Check the clean out tees periodically to determine the required cleaning schedule. 3 or 4-inch chimney brushes are
available for chimney cleaning. If the exhaust system or outside air pipes have screens on them, frequently clean the
screen. A plugged or partially plugged screen will reduce combustion air and cause a fire to die or burn poorly.
INTERIOR CHAMBERS
Open the Ash Cleanouts and scrap all ash into the ash pan. Open the damper and allow the ashes to fall into the ash
pan. The damper may need to be slid in and out several times to clear any ash build-up. This may need to be done
daily depending on fuel consumption. Be sure the ash cleanouts located on either side of the damper are completely
closed before operating.
Periodically remove and clean the burnpot and the area inside the burnpot housing. In particular it is advisable to clean
out the holes in the burnpot to remove any build up that may prevent air from moving through the burn pot freely.
Placing the Burnpot and the Agitator in a bucket of water and allowing it to soak will help with the removal of clinker build-up.
Remove the two cleanout slides on each side of the burnpot at the rear of the burn chamber to clean out all ash.
Remove the exhaust clean out plate located behind the ash pan and clean the exhaust duct of all ash.
If a vacuum is used to clean your furnace, we suggest using a vacuum designed for ash removal. Some regular vacuum
cleaner (i.e. shop vacs) may leak ash into the room.
ASH DISPOSAL
Ashes should be placed in a steel container with a tight fitting lid. The closed container of ashes should be placed on
a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes
are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all
cinders have been thoroughly cooled.
CHECK AND CLEAN THE HOPPER
Check the hopper periodically to determine if there is any fuel or fuel matter that is sticking to the hopper surface. Clean
as needed.
MAINTENANCE

MAINTENANCE
GASKETS
Inspect the main door and glass window gaskets periodically. The main door may need to be removed to have frayed,
broken, or compacted gaskets replaced by your Authorized “Breckwell” Dealer.
Also, be careful not to damage the gaskets on the backside of the cleanouts on the front of the unit. If gaskets become
torn or damaged, they must be replaced.
It is recommended that you change the door gasket (which makes your stove door air tight) once a year, in order to
insure good control over the combustion, maximum efficiency and security. To change the door gasket, simply remove the
damaged one. Carefully clean the available gasket groove, apply a high temperature silicone sold for this purpose, and
install the new gasket. You may light up your stove again approximately 24 hours after having completed this operation.
This unit’s door uses a 1/2” diameter rope gasket.
FAN MOTORS
Clean the air holes on the motors of both the draft fan and room air fans annually. Remove the draft fan from the exhaust
duct and clean out the internal fan blades as part of your fall start-up. A new gasket may be purchased from United
States Stove’s Parts Department.
Replace the customer supplied air filter on the back of the furnace on a regular basis if installed.
PAINTED SURFACES
Painted surfaces may be wiped down with a damp cloth. If scratches appear, or you wish to renew your paint, contact
your Authorized “Breckwell” Dealer to obtain a can of suitable high-temperature paint.
GLASS
We recommend using a high quality glass cleaner. Should a build up of creosote or carbon accumulate, you may wish
to use 000 steel wool and water to clean the glass. In the event you need to replace the glass, only high temperature
ceramic glass of the correct size and thickness may be used. Contact your Authorized “Breckwell” Dealer to obtain this
glass.
FALL START UP
Prior to starting the first fire of the heating season, check the outside area around the exhaust and air intake systems
for obstructions. Clean and remove any fly ash from the exhaust venting system. Clean any screens on the exhaust
system and on the outside air intake pipe. Turn all of the controls on and make sure that they are working properly. This
is also a good time to give the entire furnace a good cleaning throughout.
SPRING SHUTDOWN
After the last burn in the spring, remove any remaining fuel from the hopper and the auger feed system. Scoop out the
fuel and then run the auger until the hopper is empty and fuel stops flowing (this can be done by pressing the “ON” button
with the viewing door open). Vacuum out the hopper. Thoroughly clean the burnpot, and firebox. It may be desirable
to spray the inside of the cleaned hopper with an aerosol silicone spray if your furnace is in a high humidity area. The
exhaust system should be thoroughly cleaned.
YEARLY SERVICING
CAUTION! CLEANOUT OF THE HEAT EXCHANGER, FLUE PIPE, CHIMNEY, AND DRAFT FAN IS ESPECIALLY
IMPORTANT AT THE END OF EACH HEATING SEASON TO MINIMIZE CORROSION DURING THE SUMMER MONTHS.
A yearly inspection, servicing and cleaning by your Authorized “Breckwell” Dealer or a qualified person is recommended.
A fee may be charged for this service.
ATTENTION:
