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
•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

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. |
