PILOT FLAME PATTERN

tern. The incorrect pilot lame is not properly
heating the thermocouple. This will cause
thermocouple to cool. When thermocouple
cools, the ireplace will shut down.
If pilot lame pattern is incorrect, as shown
in Figure 32
• turn ireplace off (see
To Turn Off Gas to
Appliance,

Note: The pilot lame on natural gas units will
have a slight curve, but lame should be blue
and have no yellow or orange color.
