WARNING :
If yellow tipping occurs, your heater could produce increased levels of carbon
monoxide. If burner flame pattern shows yellow tipping, follow instructions at
bottom of this page.
NOTICE : Do not mistake orange flames with yellow tipping. Dirt or other
particles etc. enter the heater and cause transient patches of orange flame.
CARE AND MAINTENANCE :
Dust, list or debris may affect heater performance. The heater draws air into it during normal
operation. In the process dust, lint or debris will be drawn into the heater and spider webs can
build up during off season. Keep 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. Room heater may require frequent cleaning due
to excessive lint or debris depending upon the surroundings.
BEFORE CLEANING - Ensure the gas supply is off and the gas control knob
is in the off position. Make sure the heater is cool.
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.
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.).
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.
WARNING:DANGER OF BODILY INJURY
If fan assembly accessory is used, turn off power supply at disconnect
switch or service panel before removing any access panels from heater.
