BURNER FLAME PATTERN
Figure 45 shows a correct burner flame pattern.
Figure 46 shows an incorrect burner flame pat-
tern. The incorrect burner flame pattern shows spo-
radic, 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 46
• turn fireplace off (see To Turn Off Gas to Ap-
pliance, page 23)
• see Troubleshooting, pages 28 through 31
CLEANING AND
MAINTENANCE
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, 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.
Fireplace may need more fre-
quent cleaning due to exces-
sive 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 com-
pressed air no greater than 30 PSI. Your local com-
puter 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 47, page 27).
