INSPECTING

BURNER

Check pilot flame pattern and burner flame pattern often.

PILOT FLAME PATTERN

Figure 18 shows a correct pilot flame pattern. Figure 19 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.
