OWNER’S MANUAL
CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burners, and cir-
culating air passageways of fire-
place clean. Inspect these areas
of fireplace before each use. Have
fireplace inspected yearly by a
qualified service person. Fire-
place may need more frequent
cleaning due to excessive lint
from carpeting, pet hair, etc.
LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 17, to properly re-
place logs.
• Replace log(s) if broken or chipped
(dime-sized or larger).
CLEANING 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, and lint. Clean these
air inlet holes prior to each heating season.
Blocked air holes will create soot. We rec-
ommend that you clean the unit every 2,500
hours of operation or every three months.
We also recommend that you keep the burner
tube and pilot assembly clean and free of
dust and dirt. To clean these parts we recom-
mend using compressed air no greater than
30 PSI. Your local computer store, hard-
ware store, or home center may carry com-
pressed 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 direc-
tions on the can. If you don't follow direc-
tions 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 49).

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 hairs 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
pilot flame comes out of the pilot assembly
(see Figure 50). 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.
