GLASS “SOOTS” UP AT A VERY FAST RATE
FLAME IS LAZY, DARK AND HAS BLACK TIPS
AFTER STOVE HAS BEEN ON FOR A WHILE, THE BURNPOT OVERFILLS
Possible Cause:
Possible Remedies:
1. Stove or vent pipe is dirty, which restricts airflow
through the burnpot.
Follow all cleaning procedure in the maintenance section of
the owner’s manual.
2. Vent pipe installed improperly. Check to make sure the vent pipe has been installed ac-
cording to the criteria in the owner’s manual.
3. Air damper is set too far in (closed) for a higher
setting.
Put the damper knob farther out away from the side of the
stove and try not to burn the unit again.
4. Burnpot holes are blocked. Remove the burnpot and thoroughly clean it.
5. Air damper is broken. Visually inspect the damper assembly. Make sure the damp-
er plate is attached to the damper rod. When the damper
rod is moved, the plate should move with it.
6. Blockage in air intake pipe. Visually inspect the air intake pipe that leads into the burn-
pot for foreign material.
7. Circuit board malfunction. Time the fuel feed light at each setting (after the stove has
completed the startup cycle). Make sure the times match
the auger timing chart. If the auger motor runs constantly,
the board is bad.
8. Combustion blower is not spinning fast enough. Test the RPM on the blower after the blades have been
cleaned. The RPM should be approximately 3000RPM.
9. Bad Pellets
(Applies to “GLASS ‘SOOTS’ UP AT A VERY
FAST RATE” only.
The brand of pellets or the batch of pellets that are being
used may be of poor quality. If possible, try a different brand
of pellets. You might also want to try a brand that is made
from a different type of wood (softwood vs. hardwood).
Different woods have different characteristics when being
burned.
10. The trim setting on the low feed rate is too low.
(Applies to “GLASS ‘SOOTS’ UP AT A VERY
FAST RATE” only.
Use the “Reset Trim” button to increase the low feed rate
setting. If the “1” & “3” lights are on, the stove is currently
on the lowest setting. If only the “1” light is on, the stove is
in the default (medium) setting. If the “1” & “4” lights are on,
the stove is in the high trim setting for the low feed rate. If
the stove is being burned on one of the two lower settings,
advance to the next trim setting and try burning the stove.
