OWNER’S MANUAL
FRONT BURNER FLAME
PATTERN
Figure 45 shows correct front burner flame
pattern. Figure 46 shows incorrect front
burner flame pattern. The incorrect burner
flame pattern shows yellow tipping at top of
blue flame.
WARNING: If front burner
flame pattern shows yellow tip-
ping, your fireplace could pro-
duce increased levels of carbon
monoxide. Follow instructions at
bottom of this page. Yellow flame
on rear burner is normal.
NOTICE: Do not mistake orange
flames with yellow tipping. Dirt
or other fine particles are burned
by fireplace, causing brief
patches of orange flame.
If front burner flame pattern is incorrect, as
shown in Figure 46
turn fireplace off (see To Turn Off Gas to
Appliance, page 18 [Thermostat-con-
trolled models] or page 19 [Manually-
controlled models])
see Troubleshooting, pages 22 through 24

CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burners, and circu-
lating air passageways of fireplace
clean. Inspect these areas of fire-
place before each use. Have fire-
place inspected yearly by a quali-
fied service person. Fireplace 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 16, 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 47).
3. Blow air through the ports/slots and
holes in the burner.

Burner Tube
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 48). 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.
