PROBLEM CAUSE: Not enough combustion air; Fuel has to much moisture.
“Black Popcorn” is present in the burn
chamber. • Adjust the air damper to a more open position.
• Use a fuel with less moisture content
• Stove might be cycling excessively due to temperature cut backs.
• Reduce heat setting
PROBLEM CAUSE: Chemical reaction between the starch in corn and the heat.
“Clinkers” form in burnpot. • Add calcium carbonate (aka chicken scratch or oyster shell).
• Adjust air mixture
• Use corn with less moisture or starch.
PROBLEM CAUSE: Unit is reaching the “Almost Over-temp” preset.
Unit cycles up and down when on the
“HIGH” heat setting. • Adjust the heat range to lower setting.
• Fuel burns hot causing the furnace to cycle between high setting and
lower settings.
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.
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.

clear of obstructions.
• Auger system is jammed or there is a “bridging” of the fuel in the hopper,
preventing fuel from flowing into the auger feed system.
• Stove may be shutting down to an over temperturem condition.
