CAUSE: Firepot burns out of fuel
Hopper empty, refill
Auger jams. Remove auger and
clean. (Auger jams can be a prob-
lem if poor quality fuel is used. Or
excessive fines (sawdust, corn
cobs or husk) are found in hopper.
Auger jams are evident when the
auger turns but no fuel is delivered.
!
!
Improper air mixture can cause
the stove to burn fuel faster than
the auger is feeding. Reduce com-
bustion air by adjusting air
damper or increase feed rate by
changing the heat setting
.
!
CAUSE: Auger stops turning
Auger has come loose. Check to
see if auger motor is turning and
auger is not. NOTE: Auger is held
to the auger motor by a coupler
that is fastened to the auger motor
with a setscrew. Simply slide the
auger into the auger housing and
rotate until it fits into the coupler.
If coupler is loose, remove auger
motor and tighten setscrew in
coupler.

stove is extremely hot and
green light on control board is
flashing. Allow stove to cool for
1 hour and restart.

by exhaust blower not running
or venting blocked. Check
