INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Fig. 18 shows a correct pilot flame pattern. Fig. 19 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 19)
• see Troubleshooting pages 22 through 24.

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
Fig. 20 shows a correct burner flame pattern. Fig. 21 shows an incorrect burner flame
pattern. If burner flame pattern is incorrect:
• turn heater off (see "To Turn Off Gas to Appliance" on page 19).
• see Troubleshooting, pages 22 through 24.
