Trouble Shooting - PSG MAX CADDY Installation And Operating Instructions Manual

12. TROUBLE SHOOTING

PROBLEM
Heating inefficient during the first
combustions. Lack of draft.
Furnace heats well, warm air
plenum is very hot but 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 THE INSTALLATION OF A CENTRAL HEATING SYSTEM, IT IS HIGHLY
RECOMMENDED TO CONSULT A HEATING SYSTEM VENTILATION SPECIALIST.
CAUSES
Improper adjustment of the
barometric damper (opened too
wide). Chimney flue restriction
o
(too long, 90 elbows)
Improper installation of the ducts,
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 air. 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). RTD not well located
in the warm air plenum.
Wet wood, lack of draft.
Barometric damper not properly
adjusted. Soot-up chimney.
Wet wood or low grade wood.
Too much cold air return for the
hot air ducts. Unbalanced
ventilation system.
IMPORTANT NOTE

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, start-up
temperature can be adjusted on
the PC board between 125 and
150 degrees F. Reduce the fresh
air flow.
Use dry wood. Adjust the
barometric damper. Clean the
chimney flue and the furnace
exchangers.
Use dry wood. Reinstall the
ventilation system correctly.
