iNspECTiNG BURNERs
Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 30 shows a correct pilot flame pattern.
Figure 31 shows an incorrect pilot flame pat-
tern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermo-
couple to cool. When the thermocouple cools,
the fireplace will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 31
• turn fireplace off (see To Turn Off Gas to Appli-
ance, page 20 for Manual-Controlled Models
or page 21 for Remote-Ready Models)
• see Troubleshooting, page 31
Note: The correct 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 32, shows a correct burner flame pat-
tern. Figure 33, shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows sporadic, irregular flame tip-
ping. 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 33
• turn fireplace off (see To Turn Off Gas to Appli-
ance, page 20 for Manual-Controlled Models
or page 21 for Remote-Ready Models)
• see Troubleshooting, page 25
