INSPECTING BURNERS
Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 46 shows a correct pilot flame pattern.
Figure 47 shows an incorrect pilot flame pattern.
The incorrect pilot flame is not touching the ther-
mocouple. This will cause the thermocouple to
cool. When the thermocouple cools, the fireplace
will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 47
• turn fireplace off (see To Turn Off Gas to Appli-
ance, page 22 for Thermostat-Controlled Mod-
els or page 24 for Remote-Ready Models)
• see Troubleshooting, page 29
Note:
The pilot flame on natural gas units will
have a slight curve, but flame should be blue and
have no yellow or orange color.

BURNER FLAME PATTERN
Figure 48 shows a correct burner flame pattern.
Figure 49 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 49
• turn fireplace off (see To Turn Off Gas to Appli-
ance, page 22 for Thermostat-Controlled Mod-
els or page 24 for Remote-Ready Models)
• see Troubleshooting, page 29

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
fireplace clean. Inspect these
areas of fireplace before each
use. Have fireplace inspected
yearly by a qualified service
person. Fireplace may need
more frequent cleaning due to
excessive 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.
