Appendix 5: Troubleshooting
PROBLEM 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 cold air inlets).
Rearrange the ducting to respect the
minimum static pressure of 0.20 in.
w.c.
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, themodisc and damper
motor.
IMPORTANT NOTE
FOR, INSTALLATION OF A CENTRAL HEATING VENTILATION SYSTEM, IT IS
HIGHLY RECOMMENDED TO CONSULT A HEATING SYSTEM VENTILATION
SPECIALIST.
