Figures 13 and 15 show a correct pilot flame pattern. The correct<br />

flame will be blue and will extend beyond the thermocouple. The<br />

flame will surround the thermocouple just below the tip. A slight<br />

yellow flame may occur where the pilot flame and main burner<br />

flame meet. Figures 14 and 16 show an incorrect pilot flame pattern.<br />

The incorrect pilot flame is not touching the thermocouple. This will<br />

cause the thermocouple to cool. When the thermocouple cools, the<br />

heater will shut down.<br />
