Problem: Draft blower runs constantly.
21
Possible Causes:
• Defective wall thermostat.
Remedies:
• This can be checked by turning the thermostat to a lower temperature
setting than the temperature in your home. If the draft blower
continues to run, the thermostat may be defective. Replace it if necessary.
• Defective relay or transformer. • Replace relay or transformer, as necessary.
• Home is not being supplied with a
sufcient amount of heat to satisfy the
wall thermostat.
• Have a professional determine the proper size furnace and insulation factor
of your home.
• Improper thermostat wiring. • Inspect wires for damage and replace as necessary.

Problem: Rapid accumulation of creosote in furnace and ue.
• Insufcient chimney draft.
• See Troubleshooting Problem #9.
Possible Causes:
• Use of high resin wood, such as pine.
Remedies:
• Completely avoid using if at all possible. If hardwoods are not available,
fuel the furnace with smaller loads of wood. This will cause the thermostat
to call for more heat more often which will initiate the running of the draft
blower. Consequently, res will be hotter thereby reducing the accumulation
of creosote.
• Using uninsulated stove pipe for the
chimney, especially if the construction is
on the exterior of the home.
• See pages 8-9.
• Improper connection in stove pipe
causing air leakage or a structural
defect in the chimney itself.
• Inspect entire ue run, from the exhaust stack of the furnace to the
termination cap. Repair as necessary.
• Fire box not receiving an adequate
amount of oxygen.
• Furnace room may be too airtight to supply a sufcient amount of oxygen for
combustion. Install a Fresh Air Kit (WAF-FAK10).
• Use of an unlined masonry chimney
with a large clay tile opening.
• Install stainless steel liner in masonry chimney to reduce creosote formation
and to improve draw. Use appropriate size stainless liner for the furnace.
