particles of dust, dirt, lint, or pet hair with
a soft cloth or vacuum cleaner nozzle.

been pushed into burner repeat steps 3
and 4.
Clean pilot assembly also. A yellow tip on
the pilot flame indicates dust and dirt in pilot
assembly. There is a small pilot air inlet hole
about 2" from where pilot flame comes out
of pilot assembly (see Figure 36). With unit
off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if
compressed air is not available.

WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and cir-
culating air passageways of
fireplace clean. Inspect these
areas of fireplace before each
use. Have fireplace inspected
yearly by a qualified service
person. Fireplace 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.
BURNER INjECTOR HOLDER AND
PILOT AIR INLET HOLE
The primary air inlet holes allow proper
amounts of air to mix with gas. This provides a
clean burning flame. Keep these holes clear of
dust, dirt, lint, and pet hair. Clean these air inlet
holes prior to each heating season. Blocked air
holes will create soot. We recommend that you
clean the unit every 3 months during operation
and have heater inspected yearly by a qualified
service person.
We also recommend that you keep 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 injector holder for dust and dirt
(see Figure 35).
3. Blow air through ports/slots and holes in
burner.
