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

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.

Figure 32 shows correct front burner flame pattern. Figure 33 shows incorrect front

burner flame pattern. The incorrect burner flame pattern shows yellow tipping at top of

WARNING

If front burner flame pattern shows yellow tipping, your fireplace

could produce increased levels of carbon monoxide. Follow instruc-

tions at bottom of this page. Yellow flame on rear burner is normal.

NOTICE

Do not mistake orange flames with yellow tipping. Dirt or other

fine particles are burned by fireplace, causing brief patches of

orange flame.

If front burner flame pattern is incorrect, as shown in Figure 33

• turn fireplace off (see To Turn Off Gas to Appliance, page 23 [Thermostat-

controlled models} or page 25 [Manually-controlled models])
