INSPECTING HEATER

Check pilot flame pattern and burner flame pat- tern often.

PILOT FLAME PATTERN

Figure 20 shows a correct pilot flame pattern. Figure 21 shows an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down.

If pilot flame pattern is incorrect, as shown in Figure 21

•turn heater off (see To Turn Off Gas to Appliance, page 14)

•see Troubleshooting, page 17

Note: The pilot flame on natural gas units will have a slight curve, but flame should be blue and have no yellow or orange color.
