WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep con-
trol 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 person. Fireplace may
need more frequent cleaning due
to excessive lint from carpeting,
pet hair, bedding material, 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 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 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 com-
pressed 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
Figure 50).
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 as-
sembly. There is a small pilot air inlet hole about
2" from where the pilot flame comes out of the
pilot assembly (see Figures 51 or 52 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.
