11. TROUBLE SHOOTING

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., or too many 90o elbows)

Adjust the damper, minimize the chimney length and use 45o elbows.

Furnace heats well, warm air plenum is very hot by there is not much heat coming out in the room.

Improper installation of the ducts, little static pressure, unbalanced system (too many warm air outlets and not enough cold air inlets).

Reinstall the ducts correctly. Respect the minimum static pressure of 0.20 in. w.c.

Furnace consumes a lot of wood.

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 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.

Relocate the thermostat. Adjust the chain that links the damper to the damper motor. Rebalance the ventilation system in order to increase the air flow in the room where the thermostat is located.

Fan start-up is too slow.

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.

Lower the temperature starting point. The “fan ON” setting on limit control is set at 150°F, it may reduced in some particular installations. Reduce the fresh air flow. Relocate the limit control.

A lot of creosote, moderate heat output.

Wet wood, lack of draft. Barometric damper not properly adjusted. Dirty chimney.

Use dry wood. Adjust the barometric damper. Clean the chimney flue and the furnace exchangers.

Furnace heats a lot but the warm air plenum does not get hot.

Wet wood or low grade wood. Too much cold air return for the hot air ducts. Unbalanced ventilation system. Blower speed too high

Use dry wood. Reinstall the ventilation system correctly. Use a lower blower speed.

IMPORTANT NOTE

FOR, INSTALLATION OF A CENTRAL HEATING VENTILATION SYSTEM, IT IS HIGHLY RECOMMENDED TO CONSULT A HEATING SYSTEM VENTILATION SPECIALIST.
