Troubleshooting
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.
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 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 motor 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.
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 Circuit 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.
