READ THIS ENTIRE MANUAL, THOROUGHLY, BEFORE ATTEMPTING TO INSTALL AND/
OR BURN YOUR NEW AMERICAN HARVEST *MULTI-FUEL HEATER. FAILURE TO FOLLOW
THESE INSTRUCTIONS MAY RESULT IN PROPERTY DAMAGE, BODILY INJURIES OR
EVEN DEATH.
Safety Notice: If this heater is not properly installed, a house fire may result.
For your safety, follow the installation directions. Contact local building or fire of-
ficials about restrictions and installation requirements peculiar to your area. Do
Not Plug this appliance into an electrical outlet before reading and understanding
all operations and always unplug the unit before attempting any work or main-
tenance. Do not connect this heater to any chimney flue already serving another
appliance. Carefully observe and maintain all clearances to combustibles.
A note about fuel: Use only dried shelled corn with a moisture content of 14%
or less (11 to 12% provides the best results); any pellet fuel used should
have an ash content of 1% or less. If not, efficiency will suffer. This heater has
successfully burned pellets with a 2-1/2% ash content, though less ash is preferred
and more efficient.
Your American Harvest Multi-Fuel Heater operates on a negative pressure. There-
fore, all venting connections (elbows, T-pipe) must be sealed and airtight.
i
Use Hi-Temp silicone at each joint or connection.
*This heater is capable of burning wood, biomass pellets and a wide variety of grains,
including corn, soybeans, cherry and olive pits, and all larger seeds.

SAFETY STEPS
IMPORTANT: Proper installation of this heater is necessary for safe and efficient operation. In-
stalling this product improperly may result in a house fire and personal injury. All applicable building
codes for your location must be followed. In areas where building codes require additional steps to
the installation of this product not included in this manual, the building codes will take precedent
and must be followed. Contact your local building inspector to obtain any necessary permits or
inspection guidelines before installing the product.
• The American Harvest heater is designed to burn dry shelled corn, cherry pits, or pelletized fuel such as
wood and biomass pellets. The burning of other solid fuels such as cord wood or wood chips in this heater
is not permitted.
• This product requires simple periodic maintenance for proper operation and long life of the heater. Read
and follow the maintenance schedule closely.
• DISCONNECT THE POWER CORD BEFORE SERVICING THIS HEATER!
• A power surge protector is required. The unit must be plugged into a grounded 110-volt power
source. Circuit Boards are very expensive - protect yours!
• Always route the power cord away from the unit. Do not route cord in foot traffic areas. Do not pinch cord
under furniture. Do not route the cord across the exhaust pipe.
• A working smoke detector must be installed in the same room as this product.
• Flammable or explosive liquids such as gasoline, naphtha, alcohol, lighter fluid, or engine oil must NEVER
be used in or around this heater. These liquids must be stored well away from this heater as the open
flame in the burner chamber could ignite the fumes of such liquids. Do not burn garbage in this unit.
• The moving parts of this heater are propelled by high torque electric motors. The Auger and Fuel Agitator
can cause severe injury to body parts that may get near them. Keep all body parts away from the Auger
and Fuel Agitator while the heater is plugged into an electrical outlet. These moving parts may begin to
move at any time while the heater is plugged in.
• According to HUD requirements, when installed in a mobile home, this heater must be grounded directly
to the steel chassis of the mobile home and bolted to the floor. Direct air access must be provided - Use
69FAK Fresh Air Kit
• This heater is not intended for use in commercial installations.
• Do not connect this heater to “B” vent. Use UL Listed Pell Vent ONLY!
• Do not elevate the fire by use of grate or any other means other than the supplied burnpot.
BURNING SOLID FUELS
Ashes will have to be removed from the heater for proper operation. See cleaning procedure.
Your Multi-fuel heater, due to the nature of solid fuels, will require brief periodic attention. Please do not expect to light
your heater and walk away from it. A few moments of adjustment and cleaning is an important part of burning solid
fuels, due to the vast differences in fuel, humidity and outside temperature.
The Multi-fuel heater has been designed to burn dry shelled corn, wood pellets and other pelletized fuels that meet As-
sociation of Pellet Fuel Industries standards.

BURNING SOLID FUELS continued...
SHELLED CORN (Dry, preferably corn with 11- 12% moisture content)
• Corn must contain less than 14% moisture content. Wet corn will rapidly deteriorate heater 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 rem-
nants will clog the auger. Check your corn for foreign objects.
• NEVER BURN SEED CORN IN YOUR Heater. 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 and salts.
• 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 the 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 heater 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. Therefore, purchas-
ing corn from the same source will help achieve a more consistent burn. DO NOT USE CORN WITH A HIGH WAX
CONTENT!
WOOD and BIOMASS PELLETS
• As with corn, be consistent in your pellet supplier. Pellets will vary in content and burn characteristics from supplier
to supplier. A consistent supply of pellets will result in a more consistent and efficient burn.
• Check your pellets for foreign objects. Your heater warranty will not cover damage done to your heater 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 and auger tube will need to be vacuumed out after every 6-8 bags of pellets
or more often if the pellets are poor quality. The hopper should be empty of fuel when this is performed. You may
have to screen 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 heater will burn more efficiently
with small to midsize pellets (Preferred pellet size is 1/4” diameter x 1” length). Low ash content pellets will allow
you to burn the heater longer between cleanings. Only wood pellets manufactured to the Pellet Fuel Institute (P.F.I)
standard for residential pellets fuels are recommended. Performance will suffer if nonstandard pellets are used. Consult
your local American Harvest dealer for more information on approved wood pellet fuel.
CAUTION:
DO NOT PLACE SUCH FUELS WITHIN THE SPACE HEATER’S
INSTALLATION CLEARANCES OR WITHIN THE SPACE REQUIRED FOR FUELING AND
ASH REMOVAL.

GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN
It is recommended that only an authorized installer install your multi-fuel heater, preferably an NFI certified specialist.
The following installation guidelines must be followed to ensure conformity with both the safety listing of this heater and to local
building codes.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
• A UL listed 3” or 4” type “PL” pellet vent exhaust system must be used for installation and attached to the pipe connector provided
on the back of the heater. Use a 3” to 4” adapter for 4” pipe. A cap must be used at the termination of type “L” vent chimneys.
4” PL is required for elevations above 2,500 feet above sea level.
• Do not terminate vent in any enclosed or semi-enclosed area, such as; carports, garage, attic, crawl space, under a sundeck or porch,
narrow walkway or close area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway
etc.
• Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be required.
• Do not install a flue damper in the exhaust vent of this unit.
• Termination must exhaust above air inlet elevation. Installation MUST include three (3) vertical feet of pellet vent pipe. This will
create some natural draft to prevent the possibility of smoke or odor during appliance shutdown and to keep exhaust from caus-
ing a nuisance or hazard from exposing people or shrubs to high temperatures. Do not connect this unit to a chimney flue
serving another appliance. Do not connect directly to a masonry chimney.
• The installation must include a cleanout tee to enable collection of fly ash and to permit periodic cleaning of the exhaust system.
°
90 elbows accumulate fly ash and soot thereby reducing exhaust flow and performance of the heater. Each elbow or tee reduces
draft potential by 30% to 50%. Use no more than 180 degrees of elbows (two 90-degree elbows, or two 45-degree and one
90-degree elbow, etc.) and one cleanout tee to maintain adequate draft. Cleanout tees and elbows should not be connected to
the rear of the unit unless a 3-inch adapter is used.
• Total length of horizontal vent must not exceed 48”(4ft.)/1,200mm. The maximum recommended vertical venting height is 12-feet
for 3-inch type “PL” vent. For venting higher than 12-feet, 4-inch “PL” vent must be used. All joints in the vent system must be
fastened by at least 3 screws, and all joints must be sealed with RTV silicone sealer 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.
NOTE: These are guidelines only. Proper venting is accomplished by design and necessary requirements. In
most installations 3 inch diameter venting is adequate. If it does not vent properly you will have to change it to 4
inches. You should not exceed 4 inch diameter venting.
DO NOT CONNECT TO ANY AIR DISTRIBUTION DUCT OR SYSTEM
VENT TERMINATION CLEARANCES:
A) Min. 4-ft clearance below or beside any door or window that opens.
B) Min. 1-ft clearance above any door or window that opens.
C) Min. 3-ft clearance from any adjacent building.
D) Min. 7-ft clearance from any grade when adjacent to public walkways.
E) Min. 2-ft clearance above any grass, plants, or other combustible materials.
F) Min. 3-ft clearance from a forced air intake of any appliance.
G) Min. 2-ft clearance below eaves or overhang.
H) Min. 1-ft clearance horizontally from combustible wall.
I) Must be a minimum of 36-inches above the roof and 24-inches above the highest point or the roof within 10-feet.

DESIGN GUIDELINES FOR OUTSIDE COMBUSTION AIR CONNECTION
1. For installations with horizontal through-the-wall exhaust, it is strongly recommended that the heater combustion
air be connected to the outside. If the home is newer or has been tightly insulated, it is required to install outside
combustion air.
2. Connection to outside the house is REQUIRED for mobile home installations. We strongly urge use of the 69FAK
Fresh Air Kit.
90 DEGREE BEND TERMINATION
WIND HOOD TERMINATION
Wind Hood
2” Min. Diameter
3”
2”
NOTE:
6”
A wire mesh screen with a maximum
opening size of 3/8” must be
installed in the pipe or elbow for
rodent exclusion.
3. Only noncombustible pipe 2 inches (or greater) in diameter is approved to use for outside air connections (straight
or flexible). PVC pipe is NOT approved and should NEVER be used.
4. If the air inlet is connected to the outside, it MUST be terminated with a vertical 90-degree bend (down) or with a
wind hood. Failure to do so could result in a burn back during high winds blowing directly up the air inlet during a
simultaneous power failure (see diagram above).
5. Blockage, excessive length, or extra bends in the air intake pipe will starve the heater of combustion air. A 90-degree
bend is equivalent in restriction to approximately 30 inches of straight inlet pipe.
CAUTION: The operation of exhaust fans such as bath room fans, attic fans, etc. might starve the heater of combus-
tible air creating a negative pressure in the room. Provide adequate ventilation in the room accompanying the heater.
If not, the pressure switch may shut off operation of the heater. (Due to negative pressure)

DESIGN GUIDELINES FOR 6041I INSERT INSTALLATION
INSTALLATION INTO A MASONRY FIREPLACE
When installing into a masonry fireplace, DO NOT
remove any bricks or masonry, with the following
exception: masonry or steel, including the damper
plate, may be removed from the smoke shelf and
adjacent damper frame, if necessary, to accommo-
date a chimney liner. Do this only if their removal
will not weaken the structure of the fireplace or
the chimney, and will not reduce protection for
combustibles to less than that required by national
building codes.
Installation must include a chimney liner (4” Pell
Vent “PL” Piping) that extends the full height of the
chimney and meets type HT requirements. The
liner must be securely attached to the insert and
the chimney top. The chimney must be sealed
either at the top or at the damper area with a non-
combustible plate to prevent room air passage to
chimney cavity.
4” VENT IS MANDA-
TORY FOR INSERT
INSTALLATIONS.
Outside combustion air may be drawn through the
chimney top or through an existing ash cleanout.
INSTALLATION INTO A FACTORY-BUILT
(METAL) FIREPLACE
When installing into a zero clearance fireplace, The
firebox must accept the insert without modification
other than removing bolted or screwed together
pieces such as smoke shelf/deflectors, ash lips,
screen or door tracks, and damper assemblies.
These items must be re-installed if the insert is
removed and not replaced. The removal of any
part must not alter the integrity of the listed fire-
place in any way.
The factory built fireplace must be listed per UL
127. Installation must include a chimney liner (4”
Pell Vent “PL” Piping) that extends the full height
of the chimney and meets type HT requirements.
The liner must be securely attached to the insert
and the chimney top. The chimney must be sealed
either at the top or at the damper area with a non-
combustible plate to prevent room air passage to
chimney cavity.
4” VENT IS MANDA-
TORY FOR INSERT
INSTALLATIONS.
For raised hearth installations, adjust the leveling
bolts under the front of the unit.

GLASS MAINTENANCE, REMOVAL AND REPLACEMENT
Your Multi-Fuel Heater comes to you with the glass door installed in place, ready for use. The glass is surrounded
on the edges with a gasket and seated in a glass channel. It is held in place with two (2) clips.
REMOVAL OF BROKEN OR DAMAGED CERAMIC GLASS
Open the door and then lift it off of the hinges. If the door is tight, tap gently on the bottom of the door with your hand
or rubber hammer. Lay door down on newspaper with glass clips facing you. Using a #2 Phillips screwdriver, loosen the
screws and take off the glass clips. Remove the broken glass carefully and discard.
Reverse the above procedure for replacing new glass with new gasket. Do not over tighten the screws. Over tighten-
ing can cause the glass to break.
WARNING
Do not operate unit with broken glass.
Do not substitute original factory glass.
You must use only factory authorized glass;
Do not slam door shut.
Do not strike glass.
Do not use abrasive cleaners.
CLEANING THE GLASS
When the fire is first started, it will produce some smoke. The soot might accumulate on the glass surface. Before the
glass surface gets hot, open the door and wipe the glass surface off with a rag. Do not touch the surface with your
hands. If after constant use, the glass is dirty, you must clean the glass so that it will not become etched with the fly
ash. When the glass has cooled off, take a damp rag and clean with Hearth Glass Cleaner available from your dealer.
Do not use a rag that contains nylon because it will melt to the glass.

UNDERSTANDING THE CONTROL BOARD
CONTROL PANEL
Turning the heater 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 American Harvest heater. The
insert model 6041I is located on the left facade.
This unit has two fuel operation modes for different fuels, corn or pellet. It may also
be changed between an automatic operation or a manual operation in either of the
fuel modes. The heater comes from the factory in the corn mode.
Pressing the “ON” button on the control panel will begin the start-up sequence for the
heater. The start-up sequence differs depending on which fuel operation mode you
select. See Lighting Instructions for details. Pressing and holding the “ON” button
will rotate the auger continuously until button is released, which feeds additional fuel.

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 adjusting the Draft Fan setting, try only
Manual
1 setting above or below the heat setting. It is better to leave the heater in the automatic mode and adjust the manual draft slide
to control the combustion air.
The room fan will come on once the unit has reached operating temperature (approx. 110°F). By pressing the “Room Fan” buttons,
the display will show “Rf-A” which is automatic or “Rf-1” through “Rf-9” for manual settings. In auto mode, the room fan’s speed
will automatically be adjusted in accordance with the heat range setting. By pressing the “Room Fan” up arrow, you can adjust
the fan speed setting up to “Rf-9”. The fan speed can be adjusted to a higher setting than the heat setting but not lower than the
corresponding heat range.
The “Aux” button is for Agitator operation. When the unit is “OFF” and the heater is cool, 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 “Auger Delay” is normally used only during the start up cycle to slow the fuel delivery down during
the initial ignition.
The “Mode” button is used to switch between manual and automatic mode. When in auto mode, the fan, 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 manual slide damper just below the viewing door.
When the heater is in the manual mode, the optional thermostat will not properly control the unit.
During normal operation, the unit is constantly monitored for problems. In the event of an error condition, the unit will stop and an
error will be displayed. See the list of error codes found at the end of this manual.
LIGHTING INSTRUCTIONS
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.
CAUTION:
Before lighting your heater for the first time, make sure that all items are out of the hopper, ash pan and firebox area.
Close all doors and lids. Choose which fuel setting that you wish to operate in, Corn or Pellet. Do this by first pressing the “ON” button,
then press the “Heat Range” Up and Down arrows together for approximately 3-4 seconds and release. A “C” or “P” in the first digit
of the display will indicate the mode. The ON LED will be blinking and the display will show “Cr-1” or “Pr-1”, depending on the mode.
The “Heat Range” indicator LED and the “Auto” LED should be lit and the dash in the Heat Range display should be flashing. You will
notice the draft fan starts immediately. If you press the “Heat Setting” button up, the draft fan changes speed, increasing speed the
higher the heat setting. You should begin to see the igniter, located in the center and behind the burnpot, begin to glow after a short
period of time. In Corn Mode, the auger and agitator will start rotating after a few minutes, allowing for proper fuel ignition. In Pellet
Mode, the auger will turn immediately, then the agitator will begin to rotate once the heater reaches operating temperature. Note:
The room fan will not operate at this time, as a temperature of at least 110 degrees must be reached before operating. If proper
operation of your heater is confirmed, press the “OFF” button, then fill your hopper with the desired fuel. Ensure there is no foreign
matter in your fuel, hopper or burnpot. You are now ready to light your Multi-Fuel Heater.

TO START A FIRE...
• 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.
Using Wood Pellets: Ensure your display shows a “Pr” for pellets.
• Close all doors, lids, and cleanouts.
• Press the “ON” button and select desired heat range. This will start the ignition sequence.
At this point, the igniter will come on and run for preset time limit (approximately 9 minutes). The auger will begin to turn and feed
fuel into the burnpot. After the 9 minutes or if the heater reaches operating temperature, the igniter will shut off and normal opera-
tion will begin.
• Make fine adjustments to the air/fuel with the damper located centered, under the hearth.
• Once the heater reaches warm temperature, the room fan will start to circulate air into the room.
If you would like to increase the life of your ignitor, you can run your heater in the “Cr” mode. However, you must place pellets in
the burnpot, up to the igniter level as shown in the illustration below for auto ignition. Close the door and press the “ON” button. The
igniter only runs approximately half the time in “Cr” as oppose to the “Pr” mode.
Using Corn, Soy Beans, Cherry Pits: Ensure your display shows a “Cr” for corn.
NOTE: Wood pellets MUST be used for auto ignition of the fuel. Corn, Soy Beans, and Cherry Pits have a higher
flash point and requires more heat to combust as opposed to wood pellets. Trying to light the heater with a fuel
other than wood pellets will decrease the life expectancy of your igniter cartridge.
The use of starter gel or starter pellets is not required for this heater.
• Fill the burnpot with wood pellets up to the level of the igniter port; See illustration.
• Close all doors, lids, and cleanouts.
• Press the “ON” button and select desired heat range. This will start the
ignition sequence.
Once the wood fuel is ignited and the heater senses heat, the auger and
agitator will begin to rotate, feeding fuel to the burnpot. NOTE: If the start-
ing 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 continuously deliver fuel until you release the button.
• Continue to observe the fire until most of the wood pellets have been
consumed and only corn or your selected fuel is burning aggressively.
• Make fine adjustments to the air/fuel with the damper located centered,
under the hearth. You should pull the damper out approximately 1 inch.
It may need to be pulled out more or less depending on your selected
heat setting and fuel quality. Try opening or closing by a 1/4 inch at a
time.
• Once the heater reaches warm temperature, the room fan will start to circulate air into the room.
• 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.
TURNING THE HEATER OFF
Pressing the OFF button will cause the heater to enter a shutdown mode. If the heater has reached operating temperature, the
OFF Indicator will blink until the shutdown procedure succeeds in lowering the heater temperature. The Room Fan will stay on to
cool the heater, and the Exhaust Fan will stay on to remove smoke and heat from the combustion chamber. The Agitator will rotate
continuously until shutdown is complete. The Auger will bump the fuel out every few seconds to prevent the fuel in the auger from
burning. Once the temperature of the burn chamber falls below approximately 90 degrees Fahrenheit and the pressure switch detects
that the door is closed, the fans will stop and the Auger will run for a few seconds to purge the auger system of any burned fuel. At
this point, the OFF Indicator will go out and the heater will turn completely off. If during burning, the heater reached at least 120
degrees Fahrenheit, the shutdown procedure will include a 15 minute shutdown cycle that will keep the heater in the shutdown state
for at least 15 minutes regardless of whether it is cool or pressure is detected. The 15 minute cycle can be turned off by pressing
the off button during shutdown. This will cause the system to exit shutdown and return to the “OFF” mode as soon as the door is
closed and the heater is cool.
Continue to monitor the heater / insert after the shutdown procedure has begun. And remember, varying ambient conditions may
result in a lengthy period of time for adequate cool down and the resultant shut down. Be patient, this is normal. The control board is
telling the heater / insert to gradually “shut down,” rather than initiate a sudden halt of fuel to the fire pot. In this way, the possibility
of smoke entering the home is avoided.
i NEVER shutdown or unplug the heater and leave it unattended. Observe operations for at least 20 minutes.

DISPOSAL OF ASHES
Disposal of Ashes
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, 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.
MAINTENANCE INSTRUCTIONS
Soot and Flyash - Formation and Need for Removal
The products of combustion will contain small particles of flyash. The flyash will collect in the exhaust venting system
and restrict the flow of flue gases. Incomplete combustion, such as occurs during startup, shutdown, or incorrect opera-
tion of the room heater will lead to some soot formation which will collect in the exhaust venting system. The exhaust
venting system should be inspected at least once per month (of heavy use) to determine if cleaning is necessary. Corn
has a high ash content.
Daily Maintenance
• Surfaces on the front of the heater will be extremely hot during operation. Always wear heat resistant gloves
to perform periodic maintenance.
• Using a wooden stick, tap the side heat exchangers that are located on the left and right sides of the firebox. When
you open the door, they are located directly inside to the left and right. When you tap the sides with the wooden stick
the loose fly ash will drop out of these holes.
• Inspect inside heater for excessive ash build up. You will learn some fuels produce more ash than others. If excessive,
remove the inside ash clean-outs. Once you have cleaned out the ashes, replace the clean-outs. Depending on your
fuel and use, these clean-outs may be removed only weekly.
• If clinkers develops in the firepot,clean thoroughly. You may have to do this once or twice a day depending on the
moisture content of the corn. If this is not cleaned out, it could cause the agitator to jam. USSC highly recommends
an additive (see Fuel Additive) be added to your corn to eliminate these clinkers. Contact your local dealer for avail-
ability and cost. You will need this additive if the agitator “fingers” develop an accumulation or build-up.
• The clinkers on the agitator and burnpot are easily removed when soaked in warm water for 10 minutes.
• The ash pan (especially the model 6041I) should be cleaned out on a daily basis or as needed depending ash build-up.
SPECIAL CLEANING/OPERATIONAL
INSTRUCTIONS:
After cleaning or when operating the
heater, you need to make sure that “both”
clean-outs are in their proper position. If
left out or placed incorrectly, the combus-
tion air is effected greatly and the heater
will not burn properly.
Also, make sure that the ash dumps on
each side of the damper are pushed in
completely. This will also effect the com-
bustion air.

Weekly Maintenance
• Shut down the heater as directed in the operating instructions. Allow the heater to cool to room temperature. Re-
move the small clean-out slides in the lower corners of the firebox. Tap the sides of the burn chamber with a wooden
stick. Do not tap the firewall behind the burn box as it may damage the ceramic firebrick. Scrape the fly ash from the
clean-out chambers toward the front of the burn chamber. Remove the fly ash from the burn chamber and replace
the clean-outs.
• Remove the ash pan and dump the ash into a metal container.
• Cleaning of the exhaust system will depend upon the ash and debris content of your fuel. If your fuel has a high ash
content and/or significant debris in it, your exhaust system will require weekly cleaning. Cleaner fuels will allow for
monthly cleaning of the exhaust system. Remove the exhaust pipe from the back of your heater and remove any ash
that may have collected in the pipes. Replace the pipes to the heater and seal with high temperature seal tape. If
you have installed proper clean out tees you will not have to take the chimney sections apart.
Spring Cleaning
When the heating season is over make sure that you clean out all of the fuel in the hopper, firebox area, ash pan and
firepot area. Corn and any ash can accumulate moisture over the summer months causing the unit to rust and the fuel
to mold. Corn left in the unit will attract mice and can cause internal wiring and insulation damage.
When the unit is cleaned out, take the venting apart, clean out the fly ash, rinse the venting out with a water hose and
let dry, take the draft fan off and clean, clean out all areas such as back heat exchanger and lubricate the auger, auger
tube, firepot area, agitator shaft and bearings and hopper area with a light oil (something like Pam cooking oil works
great to coat the inside of the unit and the moving parts). Clean the glass, doors and outer cabinet so that you are
ready for the next heating season. Use of a wet/dry vacuum makes all cleaning easier.
AUTOMATIC SAFETY FEATURES
WARNING
These automatic safety features must not be bypassed
Power Outage
• During a power outage, the heater will shut down. It will not automatically restart when the power returns, unless
the heater is still above the proper operating temperature and a flame still exist in the burnpot.
Overheating
• A high temperature switch will automatically shut down the heater if it overheats. The heater will need to be manually
relit. Allow 45 minutes before relighting.
Hopper Safety Switch and Pressure Switch
• If the hopper lid is open, or if the front viewing door is not closed properly, the auger will not operate.
FUEL ADDITIVE
Chicken Scratch for my Corn Burner?
Yes - Crazy as it may sound, ground Oyster Shells, (calcium carbonate) same as fed to chickens, is the ideal additive to
promote clean burning, especially when the Corn Fuel is extra high in starch. And it’s available at your local Feed and
Seed.
The “average” mixture is 1/2 pound of Oyster Shells (about 2 handfuls) to 60 pound of Corn, a full hopper. IF the “fin-
gers” on your agitator (stirrer or rouser) have a noticeable buildup of “clinkers” or stubborn deposits, you have either a
high starch fuel OR are burning with too much air for proper combustion and are reaching the “fusion” temperature of
the Potassium and/or Starch in the Corn. You need Oyster Shells - and maybe more than a couple handfuls.
If you notice a heavy accumulation of “whitish powder” in your burn pot, reduce the amount of Oyster Shell Additive.
Remember, using this additive- as necessary - promotes efficiency (higher heat output), reduces maintenance, clinkers
and ash content.

Display Indicators
Several situations or events are indicated in normal operation by blinking display indicators or segments in the display:
Flashing On Indicator: This means that the heater is in the “Start Up” awaiting for the ignition procedure to complete.
Flashing Off Indicator: This indicates that the heater is in the “Shutdown” state waiting for the OFF button, or for a 15 minute period
after the heater was turned off, or for the heater to cool down, or for the door to be closed.
Flashing dash in Heat Range Display: This indicates that the heater is in the normal run mode and is ramping from the current
heat range setting to the target heat range setting. Once the ramp is complete, the dash will stop flashing. For ramping from heat
range 1 to 5, the default time is 12 minutes (with a 90 second ramp time).
Flashing heat range value in “Heat Range” display: For example, if the display is showing “Hr-3” and the ‘3’ is blinking, this indi-
cates that the heater thermostat input is open and not calling for heat. While this is happening, the actual heat range value is 1 (low).
Flashing Automatic Mode Indicator: This indicates that the heater is in normal operation and is running in the automatic mode.
However, either the Draft Fan or Auxiliary setting is manually configured.
Flashing Draft Fan Setting Indicator: This indicates that the heater is in normal operation and that the vacuum sensor detects a
loss of pressure either because the door is open or because there is a negative pressure in the room with respect to the exhaust.
Flashing Aux Indicator: This indicates that the igniter is on during the lighting stage.
Quick (changes twice per second) Flashing Heat Range Setting Indicator : This indicates that the heater is in normal operation
and that an over temperature condition exists causing the fuel to stop.
Slow (changes once per second) Flashing Heat Range Setting Indicator : This indicates that the heater is in a cutback condition
in an attempt to prevent an over temperature shutdown.
Factory Defaults
To return the control to its original factory default settings, press and hold the AUX UP and AUX DOWN buttons together for three
seconds.
