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 qualifi ed technicians should deal with possible internal electrical failures.
● Do not attempt to remove or loosen any screws from inside the fi rebox without applying penetrating oil (ie. WD40) to any of the screws.
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 fl ashing.
5. Auger light fl ashes but auger motor does not turn at all
6. The 200 °F (93 °C) high limit temperature sensor has tripped.
7. The convection blower will not function normally.
8. Ignitor- the pellets will not light.
9. Control settings (Heat Level) has no effect on the fi re.
10. The stove keeps going out.
*NOTE: All troubleshooting procedures should be carried out by qualifi ed technicians or installers.
TROUBLESHOOTING FAQ'S
1. The stove will not start.
9Make sure the stove is plugged in and the wall outlet is supplying power..
9If the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up to call for heat.
9Ensure the burn pot liner is correctly placed in the burn pot
9Check the Heat Level Indicator. - If the # 2 light is fl ashing (see the # 2 light is fl ashing)
9Check the fuse on the circuit board.
9If the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
9Check the Heat Level Indicator if a fi re is not detected, or if the fi re has gone out the #3 light will fl ash because the Exhaust Temperature Sensor’s
contacts have opened.
9Check the hopper for fuel.
9Incorrect air damper setting. - Excessive air may consume the fi re too quickly before the next drop of fuel, leaving completely unburned fuel in the
burn pot liner. - Insuffi cient air will cause build up, further restricting the air fl ow 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 fi re. 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).
9Combustion Blower failure. - The Combustion Blower is not turning fast enough to generate the proper vacuum in the fi re box. Visual Check – is
the blower motor turning.
9Check the Exhaust Blower voltage across the blower wires (>=114 V on #5 setting and >= 82 on #1 setting). – Replace the Circuit Board if the Volt-
age reading is less than 82 V. with a line voltage >115 V AC.
9Check 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 .10” W.C. on low fi re).
If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower.
9Poor Quality Fuel – Insuffi cient energy in the fuel to produce enough heat to keep the stove burning or operational.
9Exhaust Temperature Sensor failure. – Bypass sensor located on Exhaust Blower if stove now operates properly, the unit may require cleaning or
a new sensor. Contact your local dealer for service.
9Check the fuse on the circuit board.
3. The exhaust motor will not function normally.
9Open the left side access panel; check all connections against the wiring diagram.
9See “2. The stove will not operate when hot.” section.
4. Light # 2 on Heat output bar fl ashing
(The Vacuum Switch contacts have opened for more than 15 sec.)
9Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as required. Blow out Vacuum Hose
9Blocked Hose Barb on Exhaust Channel - Use a paper clip to clean out Hose Barb or remove the Vacuum Hose from the Vacuum Switch and blow
into the hose to remove blockage.
