Figure 32 - Incorrect Pilot Flame Pattern
(Propane/LP Shown)
Figure 33 shows a correct burner ame pat-
tern. Figure 34 shows an incorrect burner
ame pattern. The incorrect burner ame
pattern shows sporadic, irregular ame tip-
ping. The ame should not be dark or have
an orange/reddish tinge.
Note: When using replace for the rst time,
ame will be orange for approximately 1 hour
until log cures.
If burner ame pattern is incorrect, as shown
in Figure 34
• turn replace off (see To Turn Off Gas to
Appliance, page 21)
• see Troubleshooting, page 24

INSPECTING BURNER
Check pilot ame pattern and burner ame
pattern often.
Figure 31 shows a correct pilot ame pattern.
Figure 32 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not properly
heating the thermocouple. This will cause
thermocouple to cool. When thermocouple
cools, the replace will shut down.
If pilot ame pattern is incorrect, as shown
in Figure 32
• turn replace off (see To Turn Off Gas to
Appliance, page 21)
• see Troubleshooting, page 24
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.
