Troubleshooting

DO NOT:

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 from the firebox any screws without penetrating oil lubrication.

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.Light # 2 on Heat output bar flashing.

5.Auger light flashes but auger motor does not turn at all

6.The 93°C (200°F) high limit temperature sensor has tripped.

7.The convection blower will not function normally.

8.Igniter- the pellets will not light.

9.Control settings (Heat Level) has no effect on the fire.

10.The stove keeps going out.

*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..

üIf the Control Board has been placed in the AUTO /OFF thermostat mode, then turn the thermostat up or timer ON to call for heat.

üEnsure the burn pot liner is correctly placed in the burn pot

üCheck the Heat Level Indicator. - If the # 2 light is flashing (see the # 2 light is flashing) üCheck the fuse on the circuit board.

üIf the unit still does not start, contact your local service dealer for service.

2. The stove will not operate when hot.

üCheck the Heat Level Indicator if a fire is not detected, or if the fire has gone out the #3 light will flash because the Exhaust Temperature Sensor’s contacts have opened.

üCheck the hopper for fuel.

üIncorrect 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. In this case clean the burn pot. (NOTE: unit may require a change to the vent system or installation of fresh air to correct Air to Fuel ratio problems).

üCombustion 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.

üCheck the Exhaust Blower voltage across the blower wires (>=220V on #5 setting and >= 165V on #1 setting). – Replace the Circuit Board if the Voltage reading is less than 165 V. with a line voltage >220 V AC.

üCheck Vacuum levels in the exhaust channel by bypassing the Vacuum Switch, then remove the Vacuum hose from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a Magnahelic Gauge (readings must be above 24.9 Pa (.10” W.C.) on low fire).

If the motor fails to reach a 24.9 Pa (.10” W.C.) readings, then replace the Combustion Blower.
