INSPECTING
BURNER
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 23 shows a correct pilot flame pattern. Figure 24 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.
