Maintenance
Dust, lint, cobwebs or debris may affect heater perfor- mance. 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 passage- ways clean. Inspect or have these areas inspected annually at the beginning of the heating season by a qualified service person. Depending on the surround- ings, the room heater may require frequent cleaning due to excessive lint or debris.
Before cleaning ensure the gas supply is off and the gas control knob is in the OFF position. Make sure the heater is cool.
WARNING: Danger of bodily injury. If fan assembly accessory is used, turn off power supply at discon- nect 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 tooth- pick 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 damage.
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 (Daemyeong 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 combustion and circulating air passageways and dampened cloth to clean the cabinet/casing.
