Possible Remedies: (Unplug stove first when possible)
Follow all cleaning procedure in the maintenance section of
the owner's manual.
Check to make sure the vent pipe has been installed according
to the criteria in the owner's manual.
Pull the damper knob farther out away from the side of the
stove and try to burn the unit again.
Remove the burnpot and thoroughly clean it.
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.
Visually inspect the air intake pipe that leads into the burnpot
for foreign material.
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.
Test the RPM on the blower after the blades have been
cleaned. The RPM should be approximately 3000 RPM.
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.
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.
