INSPECTING BURNER
20
Check pilot flame pattern and burner flame pattern often.
PILOT FLAME PATTERN
Figure 19 shows a correct pilot flame pattern. Figure 20 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.
