CLEANING AND MAINTENANCE
WARNING: Turn off and un- plug furnace and let cool before cleaning. Turn equipment shutoff valve to OFF position. Only a qualified service person should service and repair furnace.
WARNING: Keep furnace clear and free from combustible mate- rials, gasoline, and other flam- mable vapors and liquids.
CAUTION: You must keep control areas, burner, and circu- lating air passageways of furnace clean. Inspect these areas of fur- nace before each use. Have fur- nace inspected yearly by a quali- fied service person. Furnace may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
CAUTION: Label all wiring prior to disconnection when ser- vicing controls. Wiring errors can cause improper and dangerous operation.
Verify proper operation after ser- vicing.
CABINET
Air Passageways
•Use a vacuum cleaner or pressurized air to clean.
Exterior
•Use a soft cloth dampened with a mild soap and water mixture. Wipe cabinet and front cover to remove dust.
•Use a vacuum cleaner to remove dust from front cover louvers.
EXHAUST AND INTAKE VENTS
Make sure the exhaust and intake vents are not blocked. The intake combustion air and the exhaust gases must be expelled to the outside. Have a qualified service person clean dirt and loose debris from vents annually.
GASKETS
Inspect all gaskets. If any gaskets show signs of leakage or damage, replace them. Safe operation of furnace depends on all gaskets being tight.
FRONT COVER
Remove anything that may be blocking the air to the louvers of the front cover.
COMBUSTION CHAMBER AND MAIN BURNER
Check flame pattern of main burner often (see Inspecting Burner Flame, page 13). Have combustion chamber and main burner cleaned if you have run the furnace with a high yellow flame. Incomplete combustion from lack of air causes the yellow flame. This deposits soot inside the combustion chamber and on the burner. Contact a quali- fied service person to clean combustion chamber and main burner.
OUTSIDE VENT CAPS
Inspect outside vent caps for obstructions or soot. If soot is found, do not use furnace. Contact a qualified service person to clean furnace.
