INSPECTING

BURNERS

Check pilot flame pattern and burner flame patterns often.

PILOT FLAME PATTERN

Figure 31 shows a correct pilot flame pat- tern. Figure 32 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. 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 32

•turn fireplace off (seeTo Turn Off Gas to Appliance, page 15 [Thermostat-con- trolled models] or page 16 [Manually- controlled models])

•seeTroubleshooting, pages 19 through 21
