Check pilot flame pattern and burner flame

PILOT FLAME PATTERN

Figure 18 shows a correct pilot flame pat-
tern. 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.
