10 Troubleshooting
PROBLEMS
CAUSES
SOLUTIONS
Heating inefficient during the
first combustions. Lack of
draft.
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
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 press0ure,
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)
Furnace consumes a lot of
wood.
Damper switch left always on.
The thermostat which controls
the damper is continuously
activated or is too close to a
source of cold air. Damper not
properly adjusted. House not
insulated enough. Ash plug
and drawer are not tightly
closed. Furnace too small for
the surface to be heated.
Unbalanced ventilation system,
very little heat where the
thermostat is located.
If manually controlled, install a
wall thermostat. Relocate the
thermostat. Rebalance the
ventilation system in order to
increase the air flow in the
room where the thermostat is
located.
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.
Wet wood or low grade wood.
No static pressure.
Unbalanced ventilation system.
Use dry wood. Rearrange the
ventilation system correctly.
Primary air inlet damper 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 damper motor.
