thermocouple to cool. When the thermo-
couple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 26
• turn heater off (see To Turn Off Gas to
Appliance, page 15)
• see Troubleshooting, pages 19 through 21

pattern. Figure 28 shows incorrect front

flames with yellow tipping. Dirt
or other fine particles are burned
by heater, causing brief patches
of orange flame.
If front burner flame pattern is incorrect, as
