CLEANING
AND
MAINTENANCE
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 31, 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 23.
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.
