Figures 41 and 43
show a correct pilot flame pattern. The correct
flame will be blue and will extend beyond the thermocouple. The
flame will surround the thermocouple just below the tip. A slight
yellow flame may occur where the pilot flame and main burner flame
meet.
Figures 42 and 44
show 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.
