CLEANING PILOT AIR INLET HOLE
Clean the 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 two inches from where the pilot flame comes out
of the pilot assembly (see Figure 65). 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. You may also clean the pilot air
inlet hole by pushing a common pipe cleaner completely through the
air inlet hole once.

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace and let cool before
cleaning.
CAUTION: You must keep control areas, burners,
and circulating 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 mate-
rial, pet hair, etc.
CLEANING BURNER INJECTOR HOLDER
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, 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 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. You
can use a vacuum cleaner in the blow position. 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, and primary air inlet holes on injector
holder for dust and dirt (see Figures 63 and 64).
3.
Blow air through the ports/slots and holes in the burner.
4.
Check the injector holder located at the end of the burner tube
again. Remove any large particles of dust, dirt, lint, or pet hair
with a soft cloth or vacuum cleaner nozzle.
5.
Blow air into the primary air holes on the injector holder.
6.
In case any large clumps of dust have now been pushed into
the burner repeat steps 3 and 4.
