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.

Follow all cleaning procedures in the maintenance section of the owner's manual.
(POF)
Check the (POF) thermodisc to see if the wires are connected properly.
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
(POF)
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 fire went out the auger will continue to feed pellets until the hopper is empty if
you leave the POF thermodisc bypassed.
Refill the hopper.
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.
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 flights, 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.
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.

The T-stat sensor has come unplugged from the control board. Check to see if the
sensor is unplugged. If the sensor is not unplugged, then the sensor is damaged or
has a short. If the sensor is damaged or has a short, it will need to be replaced.
Possible Remedies: (Unplug stove first when possible)
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.
Inspect both gaskets on the combustion blower to make sure they are in good shape.
Replace if damaged.
