WARNING: Turn off fireplace and let cool before
cleaning.
A
CAUTION: You must keep control areas, burner,
and circulating air passageways of fireplace clean.
Inspect these areas of fireplace before each use. Have
fireplace inspected yearly by a qualified service per-
son. Fireplace may need more frequent cleaning due
to excessive lint from carpeting, pet hair, bedding
material, etc.
A
WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in soot-
ing and property damage.
CLEANING BURNER INJECTOR HOLDER
AND PILOT AIR INLET HOLE
The primary air in:etl ales 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
fireplace 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 recomme.nd 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. Al low 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 Figure 60).
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.
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 pi let flame comes out
of the pilot assembly (see Figures 61 or 62 depending on model).
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.
