Q. Why am I experiencing an excess build up of creosote in the furnace?
A.
You more than likely are introducing unwanted draft into the firebox. This may
be caused by several things, including a door ajar, ash auger tube cover loose,
flipper assembly stuck. If your furnace is in a location where wind may effect the
pressure differential across the furnace, it could cause draft to leak past the flipper.
Refer to:
• “Creosote”
Q. How do you change a door hose while the furnace is in operation?
A.
Never change a door hose unless the furnace is cooled. Please refer to the firebox
door hose section in the manual for further details or contact your local dealer.
Refer to:
• “Firebox Door Hoses”
Q. My furnace combustion blower continues to run but the fire will not burn until I
open the door?
A.
Your flipper assembly is most likely stuck closed. Please refer to the combustion
blower, flipper assembly section in the manual for further details or contact your local
dealer.
B.
Pull flue cover off, check your flues, as well as chimney.
Refer to:
• “Combustion Air Blower and Flipper Assembly”
Q. Fluid is coming out of the rectangular top chimney flue?
A.
Similar to the firebox, when your furnace is initially fired up and also at times during
normal operation, the atmosphere inside the firebox and chimney flue will exceed the
dew point causing condensation.
Refer to:
• “Dew Point”
Q.
Can I burn wood?
A.
The use of wood is only allowed for ignition purposes.
