FRONT BURNER FLAME
PATTERN
Figure 33 shows correct front burner flame
pattern. Figure 34 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 34
• turn fireplace off (see To Turn Off Gas to
Appliance, page 15)
• see Troubleshooting, pages 18 through 20

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,
bedding material, pet hair, etc.
LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 13, 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, lint, and cat hair.
Clean these air inlet holes prior to each
heating season. Blocked air holes will cre-
ate soot. We recommend that you clean the
unit every three months during operation
and have heater inspected yearly by a quali-
fied 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 Figure 35).
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.

Burner Tube
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 36).
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.
