BURNER FLAME PATTERN
Figure 35 shows a correct burner flame pattern. Figure 36 shows an
incorrect burner flame pattern. The incorrect burner flame pattern
shows sporadic, irregular flame tipping. The flame should not be
dark or have an orange/reddish tinge.
Note:
When using the fireplace the first time, the flame will be
orange for approximately one hour until the log cures.
If burner flame pattern is incorrect, as shown in Figure 36
• turn fireplace off (see To Turn Off Gas to Appliance, page 18)
• see Troubleshooting, pages 20 through 22

CLEANING AND MAINTENANCE
WARNING: Turn off fireplace and let cool before
cleaning.
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 person. Fire-
place may need more frequent cleaning due to exces-
sive lint from carpeting, bedding material, pet hair, etc.
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 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
heater 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 com-
pressed air in a can. You can use a vacuum cleaner in the blow
position. If using compressed air in a can, please follow the direc-
tions 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 37).
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 pilot flame comes out
of the pilot assembly (see Figure 38). 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.
