Figure 35 shows a correct pilot ame pattern.
Figure 36 shows an incorrect pilot ame 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.
If pilot ame pattern is incorrect, as shown in
Figure 36
• turn heater off (see To Turn Off Gas to Appli-
ance, page 21
• see Troubleshooting, page 25
Note: The pilot ame on natural gas units will
have a slight curve, but ame should be blue and
have no yellow or orange color.
