TROUBLESHOOTING
DO NOT:
•
Service the stove with wet hands. The stove is an electrical appliance, which may cause a shock hazard if handled improperly.
•
Only qualified technicians should deal with possible internal electrical failures.
•
Do not attempt to remove or loosen any screws from inside the firebox 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 flashing.
5. Auger light flashes 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 fire.
10. The stove keeps going out.
*NOTE:
All troubleshooting procedures should be carried out by qualified technicians or installers.
TROUBLESHOOTING FAQ'S
1. The stove will not start.
Make sure the stove is plugged in and the wall outlet is supplying power.
If the Control Board has been placed in the ON /OFF thermostat mode, then turn the thermostat up to call for heat.
Ensure the burn pot liner is correctly placed in the burn pot.
Check the Heat Level Indicator. - If the # 2 light is flashing, see the # 2 light is flashing.
Check the fuse on the circuit board.
If the unit still does not start, contact your local service dealer for service.
2. The stove will not operate when hot.
Check 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 Sen-
sor’s contacts have opened.
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. 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).
Combustio
n 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.
Chec
k the Exhaust Blower voltage across the blower wires (>=114 V on #5 setting and >= 82 on #1 setting). – Replace the Circuit Board if the
Voltage reading is less than 82 V. with a line voltage >115 V AC.
Check 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 fire).
If the motor fails to reach a 0.10” W.C. readings, then replace the Combustion Blower.
Poo
r Quality Fuel – Insufficient energy in the fuel to produce enough heat to keep the stove burning or operational.
Exhau
st 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.
Check the fuse on the circuit board.
3. The exhaust blower will not function normally.
Open the left side access panel; check all connections against the wiring diagram.
See “2. The stove will not operate when hot.” section.
4. Light # 2 on Heat output bar flashing
(The Vacuum Switch contacts have opened for more than 15 sec.)
Pinch, break or blockage in Vacuum Hose - Check hose for pinch points or damage, replace or re-route as required. Blow out Vacuum Hose
Blocked 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.
