11 Troubleshooting
PROBLEM CAUSES SOLUTIONS
Heating inefficient during the
first combustions. Lack of
draft. If installed, improper
adjustment of the barometric
damper (opened too wide).
Chimney flue restriction (too
long. 90
o
elbows).
Adjust the damper, minimize
the smoke pipe length and use
of 45
o
elbows.
Furnace burns well, warm air
plenum is very hot but there is
not much heat coming out in
the room. Improper installation of the
ducts, low static pressure,
unbalanced system (too many
warm air outlets and not
enough fresh air return). Rearrange the ducting to
respect the minimum static
pressure of 0.20 in. W.C. (50
Pa) in the plenum.
Furnace consumes a lot of
wood. The thermostat always calls for
heat or is too close to a source
of cold air. Air controls not
properly adjusted. House not
insulated enough. Furnace
and ash drawer door not
airtight. Furnace too small for
the surface to be heated.
Unbalanced ventilation
system. Relocate the thermostat.
Rebalance the ventilation
system to increase the air flow
in the room where the
thermostat is located. Check
tightness of air controls,
furnace and ash drawer door.
A lot of creosote, moderate
heat output. Wet wood, lack of draft.
Barometric damper not
properly adjusted. Restriction
in the furnace or chimney. Use dry wood. Adjust the
barometric damper. Clean the
chimney, flue pipe and the
furnace exchangers.
Furnace heats a lot but the
warm air duct does not get hot. No static pressure.
Unbalanced ventilation
system. Wet wood or low
grade wood. Use dry wood. Rearrange the
ventilation system correctly.
Reload button LED blinking
fast Unit is overheating Leave the door closed, do not
add more wood and wait for
the end of combustion. Check
the door and the ash drawer
door for leaks. Excessive
chimney draft. Check the
tightness of the air controls.
Primary air controls never
opens. Furnace is not plugged-in.or
an electrical component is
faulty. Make sure the furnace is
plugged-in a functional power
outlet. Test and replace if
necessary, control switch,
thermostat, and air control
motor.
