Trouble Shooting Guide
• GLASS “SOOT’S” 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 Causes: Possible Remedies: (Unplug stove fi rst when possible)
1. Stove or vent pipe is dirty, which restricts airfl ow 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 according to the
criteria in the owner’s manual.
3. Air damper is set too far in (closed) for a higher setting. Pull the damper knob farther out away from the side of the stove and try
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 damper 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 burnpot 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 3000 RPM.
9. Bad Pellets.
(Applies to GLASS “SOOT’S” 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 to low.
(Applies to GLASS “SOOT’S” 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.
