Problem: Draft blower runs constantly.

• Defective wall thermostat.

• This can be checked by turning the thermostat to a lower setting

than the temperature in your home. If the draft blower continues to

run, the thermostat may be defective. Replace if necessary.

Possible Causes:

Remedies:

• Defective relay in transformer.

• Replace transformer and relay.

• Have a professional determine the proper size furnace and

insulation factor of your home.

• Home is not being supplied with

a sufficient amount of heat to

satisfy the wall thermostat.

7.

Problem: Rapid accumulation of creosote in furnace and flue.

• Use of high resin wood, such

as pine.

• Completely avoid using if at all possible. If hardwoods are not

available, fuel the furnace with smaller loads. This will cause

the thermostat to call for more heat more often, which will

initiate the running of the draft blower. Consequently, the fires

will be hotter, thereby reducing the accumulation of creosote.

Possible Causes:

Remedies:

• Under-firing the furnace has

caused low flue gas temperature.

• Install flue gas thermometer and maintain stack temperatures

between 300° and 400° F.

• See #9.

• Insufficient chimney draft.

8.

• Improper connection in stove

pipe causing air leakage or a

structural defect in the chimney

itself.

• Inspect entire flue run, from the exhaust stack of the furnace to the

termination cap. Repair as necessary.

• Fire box not receiving adequate

amount of oxygen.

• Furnace room may be too airtight to supply sufficient amount of

oxygen for combustion. Install an aperture to the outside consisting

of a minimum of 12 square inches or 4 inches round.

• Install stainless steel liner in masonry chimney to reduce creosote

formation and improve draw. Use appropriate size stainless liner for

the furnace.

• DANGER: Never use uninsulated stove pipe as chimney. It must not

be used on the inside of your home due to high stack temperatures,

which create an extreme fire hazard. Uninsulated pipe cannot be

used as an outside flue because it causes rapid cooling of the stack

gases, which causes them to condense as creosote on the inside of

the flue.

• Use of an unlined masonry

chimney with a large clay tile

opening.

• Using uninsulated stove pipe

for the chimney, especially if the

construction is on the exterior of

the home.
