INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot flame pattern. Figure 21 shows a incorrect pilot flame pattern. The
incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool,
which shuts the heater off. If pilot flame pattern is incorrect
:
• turn heater off (see “To Turn Off Gas to Appliance” on page 20)
• see
Troubleshooting
pages 23 through 25.

WARNING:
If yellow tipping occurs, your heater could produce increased levels of carbon
monoxide. If burner flame pattern shows yellow tipping, follow instructions at bottom of this
page.
Notice:
Do not mistake orange flames with yellow tipping. Dirt or other fine particles enter the heater
and burn causing brief patches of orange flame.
BURNER FLAME PATTERN
Figure 22 shows a correct burner flame pattern. Figure 23 shows an incorrect burner flame
