Inspecting Burner
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 31 shows a correct pilot flame pattern. Figure 32 shows an incorrect pilot flame pat- tern. The incorrect pilot flame is not properly heating the thermocouple. This will cause thermocouple to cool. When thermocouple cools, the fireplace will shut down.
If pilot flame pattern is incorrect, as shown in Figure 32
•turn fireplace off (see To Turn Off Gas to Appliance, page 21)
•see Troubleshooting, page 24
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 33 shows a correct burner flame pat- tern. Figure 34 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 fireplace for the first time, flame will be orange for approximately 1 hour until log cures.
If burner flame pattern is incorrect, as shown in Figure 34
•turn fireplace off (see To Turn Off Gas to Appliance, page 21)
