PROBLEM CAUSE(S) SOLUTIONS
1. Fire burns with
a lazy orange
flame. Pellets
build up in the
grate and the
window gets
sooted up.
There is insufficient combustion air. 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 Exhaust Blower.
2. Fire goes out
or stove shuts
down automati-
cally
The hopper is empty
Pellets are not feeding.
The high limit temperature switch
has tripped.
There is too much combustion air
for the amount of fuel.
Refill hopper.
See Pellets will not feed (#3) below.
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 room
air blower 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 disc should be replaced
by your authorized Lennox Hearth Products dealer.
Adjust the damper to reduce combustion airflow.
3. Pellets will not
feed.
Stove has run out of fuel.
The auger motor or circuit board
may be defective. The pressure
switch tap or hose may be blocked.
Back pressure in venting tripping
pressure switch.
Thermostat is in stand-by mode.
Thermostat wires disconnect.
High limit switch may have been
tripped.
Self-aligning bearing in auger motor
may be mis-aligned.
Refill hopper.
Check to be sure that there is no blockage in the pressure
tap or hose. Have your authorized Lennox Hearth Products
dealer diagnose the problem and clean or replace any nec-
essary parts.
If new installation check for excessive 90 ˚ bends, long hori-
zontal 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 room air blower setting.
Gently tap the auger motor.
