The air inlet, burnpot, interior
combustion air chambers,
combustion blower, or
exhaust pipe are blocked
with ash or foreign material.
Follow all cleaning procedures in the maintenance section of the owner’s
manual.
The Proof of Fire (POF)
thermodisc has came
upluged.
Check the (POF) thermodisc to see if the wires are connected properly.
The Proof of Fire
(POF) thermodisc has
malfunctioned.
Temporarily bypass the POF thermodisc by disconnecting the two wires and
connecting them with a short piece of wire. Then plug the stove back up. If the
stove comes on and works, you need to replace the POF thermodisc. This is for
testing only. DO NOT LEAVE THE THERMODISC BYPASSED. Your blowers will never
shut off and if the re went out the auger will continue to feed pellets until the
hopper is empty if you leave the POF thermodisc bypassed.
The hopper is out of Pellets. Rell the hopper.
The hopper safety switch has
failed or hopper is open.
When operating the unit, be sure the hopper lid is closed so that the hopper
safety switch will activate. Check the wires leading from the hopper safety switch
to the control panel and auger motor for secure connections. Use a continuity
tester to test the hopper safety switch; replace if necessary.
The auger shaft is jammed.
Start by emptying the hopper. Then remove the auger motor by removing the
auger pin. Remove the auger shaft inspection plate in the hopper so that you
can see the auger shaft. Gently lift the auger shaft straight up so that the end
of the auger shaft comes up out of the bottom auger bushing. Next, remove
the two nuts that hold the top auger biscuit in. Then rotate the bottom end of
the auger shaft up towards you until you can lift the shaft out of the stove. After
you have removed the shaft, inspect it for bent ights, burrs, or broken welds.
Remove any foreign material that might have caused the jam. Also, check the
auger tube for signs of damage such as burrs, rough spots, or grooves cut into
the metal that could have caused a jam.
The auger motor has failed.
Remove the auger motor from the auger shaft and try to run the unit. If the
motor will turn, the shaft is jammed on something. If the motor will not turn, the
motor is bad.

There is a leak in the vent
pipe system.
Inspect all vent pipe connections. Make sure they are sealed with RTV silicone
that has a temperature rating on 500°F or higher. Also, seal joints with UL-181-
AP foil tape. Make sure the square to round adapter piece on the combustion
blower has been properly sealed with the same RTV.
The gasket on the combustion
blower has gone bad.
Inspect both gaskets on the combustion blower to make sure they are in good
shape. Replace if damaged.
Because it is a wood-burning device, this heater may emit a faint wood-burning odor. If it increases beyond
normal, or if you notice an unusual soot build-up on walls or furniture, check your exhaust system carefully
for leaks. All joints should be properly sealed. Clean the stove following the instructions in “Maintenance”. If
problem persists, contact your dealer.
