Q. My furnace is shut down but still continues to increase in water temperature?
a.
There is an air leak somewhere in the furnace. Check all flippers and seals, ensuring that there is an
airtight seal.
Refer to:
• Checking for air leaks (Located in Air Leaks).
7.
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 or the A.R.D. flipper
ajar. 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 Build-up (Located in Trouble Shooting and Solutions).
8.
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 and Elbows (Located in Firebox and Other Components).
9.
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.
Refer to:
• Combustion Air Blower and Flipper Assembly (Located in Air Supply).
10.
Q. Water 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:
• Furnace has excessive moisture in firebox (Located in Trouble Shooting and Solutions)
• Dew Point (Located in Safe Operating Guidelines).
