INSPECT THE BURN POT
When burning, the fl ames should be bright orange
with embers jumping from the burn pot.
MAKE SURE PELLETS ARE NOT PILING UP
If the pellets build up over the burn pot, turn the pellet
feed switch to "OFF".
If the fl ames seem to be coming only from the sides,
or are orange/black, turn the heater off and check for
build up.
The most likely causes are:
1. Feed rate has been set to maximum for an
extended period of time. Turn feed rate to
optimum.
2. The door, glass, or ash pan is open or has an air
leak.
3. The burn pot requires cleaning.
4. The exhaust system requires cleaning.
5. The heater requires adjustment.
6. Poor pellet quality

CLEANING THE BURN POT
WARNING:
Make certain the heater has fully cooled (approxi-
mately 25 minutes) before opening the door and
conducting service.
To clean the burn pot, open the door and knock
away any debris on the burn pot with cleaning tool. If
severely clogged, remove the burn pot to gain better
access.
Use the hook end of the tool inserting it into the hole
located at the front of the burn pot. Once securely
in place, lift the burn pot up and set aside on a
non-combustible surface. See Figure 25. Using the
scraping tool, remove all material that has accumu-
lated in the burn pot.
Re-install the burn pot ensuring ignition hole lines up
with the ignitor.
