SOLUTIONS
Remove any clinkers or ash from the bottom of the grate that might
be obstructing the primary air holes.
Change to a better grade of fuel if necessary.
Check that the damper has been opened enough for the amount of
fuel feed.
Check that the heat exchange tubes are not coated with ash.
Clean internal exhaust ducts.
Check gasket seal around the door. Use a thin strip of paper, 1 in.
wide. Open the door and close it on the paper strip. A slight friction
should be felt when the paper strip is pulled. Repeat this process at
various locations around the door gasket. Replace the door gasket
if necessary.
Check for blockage in the air inlet tube or exhaust pipe. Clean as
necessary.
Close ash slide plates.
Have your authorized Lennox Hearth Products dealer check your
combustion blower.
Refill hopper.
See (Pellets will not feed) this page.
Allow stove to cool for 1 hour and re-light. If the stove has been
operating at a medium to high burn rate and the convection fan has
been turned down low then the fan should be turned up higher. If
this problem persists (particularly at lower burn rates) then the high
limit snap switch should be replaced by your authorized dealer.
Adjust the damper to reduce combustion air flow.
Refill hopper.
Check to be sure that there is no blockage in the pressure tap or
hose. Have your authorized Lennox Hearth Products dealer diag-
nose the problem and clean or replace any necessary parts.
If new installation check for excessive 90˚ bends, long horizontal
runs or excessive vertical run of 3" pipe. Possibly change to 4"
pipe. If older installation check for excessive ash accumulation in
pipe or other obstructions. Clean out pipe.
Check to see if thermostat is set to low or if sun is shining directly
on thermostat.
Re-install wires.
Allow stove to cool. Increase convection blower setting.
Have dealer check operation to determine if adjustment or re-

placement is necessary.
Gently tap the auger motor.
Check that the stove is plugged in to the wall outlet.
Check to see if your circuit breaker has tripped.
Check the wire connections on the high limit snap switch and con-
trol board.
