Trouble Shooting - PSG 15 Kw Installation And Operating Instructions Manual

11. TROUBLE SHOOTING

PROBLEM
Heating inefficient during the first
combustions. Lack of draft.
Furnace heats well, warm air
plenum is very hot by there is not
much heat coming out in the
room.
Furnace consumes a lot of wood.
Fan start-up is too slow.
A lot of creosote, moderate heat
output.
Furnace heats a lot but the warm
air plenum does not get hot.
FOR, INSTALLATION OF A CENTRAL HEATING VENTILATION SYSTEM, IT IS
HIGHLY RECOMMENDED TO CONSULT A HEATING SYSTEM VENTILATION
CAUSES
Improper adjustment of the
barometric damper (opened too
wide). Chimney flue restriction
o
(too long. 90 elbows)
Improper installation of the ducts,
little static pressure, unbalanced
system (too many warm air
outlets and not enough cold air
inlets).
The thermostat which controls
the damper is continuously
activated and is too close to a
source of cold. Damper not
properly adjusted. House not
insulated enough. Ash drawer is
not tightly closed. Furnace too
small for the surface to be
heated. Unbalanced ventilation
system, very little heat where the
thermostat is located.
Fan "ON" setting too high.
Return air is too cold
(temperature lower than 65
degrees). Limit control not well
located in the warm air plenum.
Wet wood, lack of draft.
Barometric damper not properly
adjusted. Sooted up chimney.
Wet wood or low grade wood.
Too much cold air return for the
hot air ducts. Unbalanced
ventilation system.
IMPORTANT NOTE
SPECIALIST
SOLUTIONS
Adjust the damper, minimize the
chimney length and use 45
elbows.
Reinstall the ducts correctly.
Respect the minimum static
pressure of 0.20 in. w.c.
Relocate the thermostat. Adjust
the chain that links the damper to
the servo-motor. Rebalance the
ventilation system in order to
increase the air flow in the room
where the thermostat is located.
Lower the temperature starting
point. Usually, the limit control is
set at 150 degrees, we can under
certain conditions, reduce this
temperature. Reduce the fresh air
flow. Relocate the limit control.
Use dry wood. Adjust the
barometric damper. Clean the
chimney flue and the furnace
exchangers.
Use dry wood. Reinstall the
ventilation system correctly.
