Cleaning and Maintenance

WARNING

Turn off heater and let cool before cleaning or servicing.

WARNING

Keep heater clear and free from combustible materials, gasoline, and other flammable vapors and liquids.

CAUTION

You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater and venting system inspected yearly by a qualified service person. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, etc.

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 the cabinet to remove dust.

COMBUSTION CHAMBER AND BURNER

Clean the combustion chamber and burner if you have run the heater with a high yellow flame. Incomplete combustion from lack of air causes the yellow flame. This will deposit soot inside the combustion chamber and on the burner. To clean combustion chamber and burner, you must remove the burner from heater. See

Service Procedures, page 28, to remove burner. After removing burner, blow inside of combustion chamber clean with compressed air. Clean burner with a steel-wire brush. Blow soot from burner with compressed air.

PILOT

Use a vacuum cleaner, compressed air, or small, soft-bristled brush to clean.

BURNER ORIFICE

Use a vacuum cleaner, compressed air, or small, soft-bristled brush to clean. You can also use a tooth pick to clean orifice. Do not enlarge or damage orifice hole.

PILOT AND BURNER FLAME

Check the pilot and burner flame monthly. Make sure pilot and burner flame is burning correctly. See Inspecting Pilot and Burner Flame, page 21.

VENTING SYSTEM

Check the venting system at least once a year. Make sure joints are secure and vent pipe is in good condition. Do not obstruct combustion and ventilation air entering the rear of heater.

BLOWER MOTOR (For Models with Blower)

The motor on a new blower is properly lubricated at the factory. The first heating season, the motor will need no additional care. At the beginning of each season afterwards, place a few drops of SAE 20 motor oil in the lubrication holes of motor. Locate the lubrication holes at front and rear of motor on motor casing.
