TROUBLE SHOOTING
PROBLEM
CAUSE:
Too rich air/fuel mixture
Orange, lazy flame, excessive fuel build-up in
the burnpot.
• Clean out the burnpot
• Make sure the cleanouts on each side of the damper are closed completely.
• Not enough combustion air. Adjust the air damper to a more open position.
• Make sure that the viewing door is closed and sealed properly. If not, adjust the door catch or
replace the gasket.
• Check that all outside connections are clear of any obstructions.
• Check the exhaust system, clean as needed.
PROBLEM
Cause:
Burnpot out of fuel
Fire goes out or heater shuts down
• Hopper is empty, refill the hopper
• Loss of draft pressure. Make sure the viewing door is closed and sealed properly. Check the
outside connections for any obstructions. Check the exhaust system; clean as needed.
• Check that the pressure switch connection to the firebox is free of ashes or clear of any ob-
structions.
• Auger system may be jammed or there is a “bridging” of fuel in the hopper preventing fuel flow
into the auger feed system.
• Too much combustion air. Adjust damper to a more closed position.
PROBLEM
Cause:
Auto-Start Igniter fails to ignite the fuel in the burnpot.
Heater does not start a fire when the “ON” but-
ton is pressed.
• Check the pellets quality. If moist or damp, replace with dryer fuel.
• Check that the auto-start igniter port is not blocked with ash or soot. (The igniter is located
behind the burnpot.)
• The auto-start igniter should glow on start-up. If you can not visible see the igniter glowing,
then it may need to be replaced or there is a problem with the electrical system. Check wiring.
• Loss of draft pressure. Make sure the viewing door is closed and sealed properly. Check the
outside connections for any obstructions. Check the exhaust system; clean as needed.
PROBLEM
Cause:
Not enough combustion air or fuel has too much moisture.
Viewing glass becomes black shortly after start-
up.
• Adjust the air damper to a more open position.
• Use a fuel with less moisture content.
PROBLEM
Cause:
Not enough combustion air or fuel has too much moisture.
“Black Popcorn” is present in the burn chamber. • Not enough combustion air. Adjust the air damper to a more open position.
• Check moisture content in corn. Use corn with a moisture content of 11-12% or less.
PROBLEM
Cause:
Corn is wet or has a high moisture content.
Corn builds up in burnpot or is not burning
completely. Steam is coming from corn.
• Not enough combustion air. Adjust the air damper to a more open position.
• Check moisture content in corn. Use corn with a moisture content of 11-12% or less.
PROBLEM
Cause:
Chemical reaction between the starches in corn and the heat.
“Clinkers” form in burnpot and on agitator.
• Adjust air mixture.
• Add calcium carbonate (aka chicken scratch or oyster shell)
• Try running a mixture of wood pellets and corn.
i
Disconnect the power supply before performing any maintenance! NOTE: Turning the heater to “OFF” does
not disconnect the power to all of the electrical components of the heater.
i
Never try to repair or replace any part of the heater unless instructions for doing so are given in this manual.
All other work should be done by a trained technician.
