TROUBLESHOOTING
Blocked exhaust / venting system - Have stove and venting cleaned and inspected.
Severe negative pressure in area where unit is installed - Check the operation by opening a window, does this solve the problem? If it does, install
fresh air intake to unit or room. Venting system may require vertical section to move termination into a low pressure zone.
Vacuum Switch failure - Bypass the vacuum switch, if this corrects the problem check for above problems before replacing the Vacuum Switch.
Damage to gray wires between Circuit Board and Vacuum Switch - Inspect wires and connectors
Combustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper vacuum in the Exhaust Channel.
Visual Check; is the blower motor turning? Check the Exhaust Blower voltage across the blower wires (>=114 V on #5 setting and >= 82 V on #1
setting). – Replace the Circuit Board if the Voltage reading is less than 82 V. with a line voltage >114 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
To reset Ci
rcuit Board after a trouble code - push the ON/OFF button
5. Auger light flashes but auger motor does not turn at all
.
If
the Auger gear box does not turn but the motor’s armature does try to spin then the auger is jammed. – Try to break apart jam by poking at the
jam through the drop tube. If this fails then empty the hopper and remove the Auger Cover **Remember to re-seal the cover after installation**
Check the fuse on the circuit board.
6.
Light #4 – 200°F ( 93°C) high limit temperature sensor has tripped.
Res
et sensor and determine cause – was it Convection Blower failure or 160 °F ( 71 °C) Temperature Sensor failure? Bypass the 160 °F ( 71 °C)
sensor, does the Convection blower come on high? If not, replace the blower. If yes, replace sensor (located on the left side of the firewall).
Check the fuse on the circuit board.
7
. The convection blower will not function normally.
Clean all grill openings at the back and below unit .
Press the fan button; does the fan come on? Press again to verify that the blower turns on; if, not contact your local dealer for service.
8. Ignitor- the pellets will not light.
Everything else in the stove operates but the ignitor will not light the pellets.
Make sure the burn pot liner is up tight and square to the ignitor tube by pushing the burn pot back against the ignitor tube.
Check to see if the exhaust blower is operating. If not, contact your local dealer for service.
Check the fuse on the circuit board.
NOTE:
The ignitor should be bright orange in color. If not replace the ignitor.
9. Control settings (Heat Level) has no effect on the fire.
NOT
E: If the system light is flashing the Control Board has complete control of the unit. When the units system light becomes solid then control of
the unit is given back to the operator.
If there is no control of the Heat Level button make sure the thermostat is calling for heat.
Call your local dealer for service.
10. The stove keeps going out.
If the stove
goes out and leaves fresh unburned pellets or cigarette-like ashes in the burn pot liner, the fire is going out before the stove shuts off.
Check to see that the Slider / Damper is in the correct position.
Turn the Heat Level up slightly (poor quality pellets will require slightly higher settings).
Set the auger trim till the #1 and #5 lights are illuminated.
If the stove goes out and there are partially burned pellets left in the burn pot liner, the stove has shut down due to a lack of air, exhaust temperature,
or power failure.
Adjust the Slider / Damper.
Check to see if the stove needs a more complete cleaning.
Did the power go out?
Contact your local Dealer for service.
