Cleaning And Maintenance - Desa BG30N Safety Information And Installation Manual

CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualified service person. Heater
may need more frequent clean-
ing due to excessive lint from
carpeting, bedding material, pet
hair, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air or small,
soft bristled brush to clean.
BURNER PILOT AIR INLET
The primary air inlet hole allows the proper
amount of air to mix with the gas. This provides a
clean burning flame. Keep this hole clear of dust,
dirt and lint. Clean this air inlet hole prior to each
heating season. A blocked air hole will create soot.
We recommend that you clean the unit every three
months during operation and have heater inspected
yearly by a qualified service person.
We also recommend that you keep the burner
tube and pilot assembly clean and free of dust and
dirt. To clean these parts we recommend using
compressed air no greater than 30 PSI. Your local
computer store, hardware store or home center may
carry compressed air in a can. If using compressed
air in a can, please follow the directions on the can.
If you don't follow directions on the can, you could
damage the pilot assembly.

1. Shut off the unit, including the pilot. Allow
the unit to cool for at least thirty minutes.
2. Inspect burner, pilot for dust and dirt.
3. Blow air across the ports/slots and holes in the
burner.
4. Never insert objects into the pilot tube.
Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as-
sembly. There is a small pilot air inlet about two
inches from where the pilot flame comes out of
the pilot assembly (see Figure 25). With the unit
off, lightly blow air through the air inlet. You may
blow through a drinking straw if compressed air
is not available.
CABINET
Air Passageways

Exterior
Use a soft cloth dampened with a mild soap and
water mixture. Wipe the cabinet to remove dust.
