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 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 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.
