CLEANING AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep con-
trol areas, burner and circulating
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 cleaning 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 holes allow the proper
amount of air to mix with the gas. This provides a
clean burning flame. Keep these holes clear of dust,
dirt and lint. Clean these air inlet holes prior to each
heating season. Blocked air holes 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
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 (200 kPa).
Your local computer store, hardware store or home
center may carry compressed air in a can. You can
use a vacuum cleaner in the blow position. If using
compressed air in a can, please follow the direc-
tions on the can. If you don't follow directions on
the can, you could damage the pilot assembly.

Clean the pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot as-

inches from where the pilot flame comes out of
the pilot assembly (see Figure 23). With the unit
off, lightly blow air through the air inlet. You may
blow through a drinking straw if compressed air
is not available.
