CLEANING
AND
MAINTENANCE
26
Turn off heater and let cool before cleaning or servicing.
Keep heater clear and free from combustible materials,
gasoline, and other flammable vapors and liquids.
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 33, to remove burner. After removing burner, blow inside
of combustion chamber clean with compressed air. Clean burner with a soft-bristled
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 24.
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.
