INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT FLAME PATTERN
Figure 20 shows a correct pilot ame pattern. Figure 21 shows a incorrect pilot ame pattern. The
incorrect pilot ame is not touching the thermocouple. This will cause the thermocouple to cool,
which shuts the heater off. If pilot ame 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 ame pattern shows yellow tipping, follow instructions at bottom of this
page.
Notice: Do not mistake orange ames with yellow tipping. Dirt or other ne particles enter the heater
and burn causing brief patches of orange ame.
BURNER FLAME PATTERN
Figure 22 shows a correct burner ame pattern. Figure 23 shows an incorrect burner ame
pattern. If burner ame pattern is incorrect:
• turn heater off (see “To Turn Off Gas to Appliance” on page 20).
• see Troubleshooting, pages 23 through 26.
