Troubleshooting

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 0.18” to 0.20” W.C. (44.8 to 49.8 Pa) on low fire). If the motor fails to reach a 0.10” W.C. readings, then replace the combustion blower.

üPoor quality fuel – insufficient energy in the fuel to produce enough heat to keep the stove burning or operational.

üExhaust 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.

üThe burn pot liner may require cleaning. Build up in the burn pot will cause the unit to shut off. üCheck the fuses on the circuit board (see “TROUBLESHOOTING - FUSES”).

üContact your local dealer for service.

3. The exhaust motor will not function normally.

üOpen the left side access panel; check all connections against the wiring diagram. üSee “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.)

üPinch, break or blockage in vacuum hose - check hose for pinch points or damage, replace or re-route as required. Blow out vacuum hose

üBlocked 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.

üBlocked exhaust / venting system - have stove and venting cleaned and inspected.

üSevere 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.

üVacuum switch failure - bypass the vacuum switch, if this corrects the problem check for above problems before replacing the vacuum switch.

üDamage to gray wires between circuit board and vacuum switch - inspect wires and connectors

üCombustion 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 (>=114V on #5 setting and >= 82V on #1 setting). – Replace the circuit board if the Voltage reading is less than 82V. with a line voltage >114V 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 .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. The auger motor will not function normally.

üThe burn pot liner may require cleaning. Build up in the burn pot will cause the unit to shut off. üCheck for obstructions in the hopper system.

üEnsure door is closed and ash pan is closed. The auger motor will stop if there is not enough vacuum in the stove.

üCall your local dealer for service.

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

üIf 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**

üCheck the fuses on the circuit board (see “TROUBLESHOOTING - FUSES”).
