Repair should be done by a qualified service person.
The appliance should be inspected before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding material, etc. It is imperative that control compartments, burners and circulating air passageways of the heater be kept clean. Dust, lint, cobwebs or debris may affect heater performance. The heater draws air into it during normal operation and in the process dust, lint or debris may be drawn in also. It is important to keep the burner, gas control and combustion and circulating air passageways clean. Inspect or have these areas inspected annually at the beginning of the heating season by a qualified service person. Depending on the surroundings, the room heater may require frequent clean- ing due to excessive lint or debris.
Before cleaning ensure the gas supply is off and the gas con- trol knob is in the OFF position. Make sure the heater is cool.
WARNING: Danger of bodily injury. If fan assembly accesso- ry is used, turn off power supply at disconnect switch or service panel before removing any access panels from heater.
BURNER AND ODS PILOT CLEANING
Clean the exterior with soft bristle brush, vacuum cleaner or pressurized air. Never use a wooden toothpick as it may break off and clog the ODS pilot or main burner port.
Use a flashlight to inspect the main burner inlet to ensure it is not blocked. If obstruction can be seen, use a metal wire coat hanger that has been straightened out. Use a vacuum cleaner to clean the primary air openings to the main burner(s).
WARNING: Failure to keep the primary air openings to the burner(s) clean may result in sooting and property dam- age.
In order to clean ODS pilot orifice, use pressurized air to blow dust out. Sometimes blowing air backwards through the pilot will get rid of the accumulated dirt. If that does not work blow out any dust through primary air openings of pilot assemblies (This unit has two openings; one beneath the bimetal strip and the second one opposite from bimetal strip. Use the one wide open, do not try to lift the bimetal strip.)
CLEANING AIR PASSAGEWAYS AND
UNIT CASINGS
Use a vacuum cleaner or pressurized air to clean the combus- tion and circulating air passageways and dampened cloth to clean the cabinet/casing.
