Figure 31 - Incorrect Pilot Flame Pattern

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 30 shows a correct pilot flame pattern. Figure 31 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 31

• turn heater off (see To Turn Off Gas to Appliance, page 25).

• see Troubleshooting, pages 28 through 31.
