INSPECTING BURNERS

Check pilot flame pattern and burner flame pat-
terns often.
PILOT FLAME PATTERN
Figure 45 shows a correct pilot flame pattern.
Figure 46 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 46
• 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.
