Troubleshooting
DO NOT:
• Hold the ON / OFF BUTTON; this is a momentary contact switch and can be damaged if held down too
long.
• Service the stove with wet hands. The stove is an electrical appliance, which may pose a shock hazard
if handled improperly. Only qualified technicians should deal with possible internal electrical failures.
• Do not remove any screws in the firebox without first lubricating them with penetrating oil.
WHAT TO DO IF:
1. The stove will not start.
2. The stove will not operate when hot.
3. The exhaust blower will not function normally.
4. The convection blower will not function normally.
5. Ignitor : The pellets will not light.
6. The auger motor does not function normally.
7. Control settings (heat level) have no effect on fire.
8. The stove will not shut off.
9. The stove keeps going out.
10. The #2 light is flashing.
*NOTE: All troubleshooting procedures should be carried out by qualified technicians or
installers.
1. The stove will not start.
üMake sure the stove is plugged in and the wall outlet is supplying power.
üPush the ON /OFF button.
üIf the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up to
call for heat.
üIf the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
«Check the hopper for fuel.
«Incorrect air damper setting - Excessive air may consume the fire too quickly before the next drop of
fuel, leaving completely unburned fuel in the burn pot liner. Insufficient air will cause build up, further
restricting the air flow through the Burn Pot Liner. This, in turn, will cause the fuel to burn cold and very
slowly. Fuel may build up and smother the fire. (NOTE: Unit may require a change to the vent
system or installation of fresh air to correct Air to Fuel ratio problems).
«Combustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper
vacuum in the fire box. Visual Check – is the blower motor turning?
«Check Vacuum levels in the firebox with a Magnahelic gauge and an 1⁄8” tube placed through the small
hole under the ash sill (readings must be above .13” W.C. on low fire).
Note: If the motor fails to reach a 0.13” W.C. reading, then replace the Combustion Blower.
«Poor Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning
or operational.
«Exhaust Temperature Sensor failure – Bypass sensor located on Exhaust Channel. If stove now operates
properly, the unit may require cleaning or a new sensor. Contact your local dealer for service.
«The unit may require cleaning. Contact your local dealer for service.
«The third red LED light in the heat level indicator light will flash if a fire is not detected or if the fire has
gone out.
