WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and circu-
lating air passageways of heater

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.

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
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 dam-
age the pilot assembly.
1. Shut off unit, including pilot. Allow unit to
cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet
holes on orifice holder for dust and dirt
(see Figure 24).
3. Blow air through the ports/slots and holes
in the burner.
4. Never inset objects into the pilot tube.
5. Blow air into the primary air holes on the
orifice holder.
Clean pilot assembly also. A yellow tip on the
pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot flame comes out
of the pilot assembly (see Figure 30). With the
unit off, lightly blow air through the air inlet
hole. You may blow through a drinking straw
if compressed air is not available.
