INSPECTING BURNERS
Check pilot ame pattern and burner ame patterns often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot ame pattern. Figure 20 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.

monoxide. If burner ame pattern shows yellow tipping, follow instructions at bottom of this

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.

pattern. If burner ame pattern is incorrect:
