Check pilot ame pattern and burner ame
patterns often.
Figure 43 shows a correct pilot ame pattern.
Figure 44 shows an incorrect pilot ame pat-
tern. The incorrect pilot ame is not touching
the thermocouple. This will cause the thermo-
couple to cool. When the thermocouple cools,
the replace will shut down.
If pilot ame pattern is incorrect, as shown
in Figure 44
• turn replace off (see To Turn Off Gas to
Appliance, page 24)
• see Troubleshooting, page 30
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.
Figure 45 shows a correct burner ame pat-
tern. Figure 46 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 the replace the rst time,
the ame will be orange for approximately one
hour until the log cures.
If burner ame pattern is incorrect, as shown
in Figure 46
• turn replace off (see To Turn Off Gas to
Appliance, page 24)
• see Troubleshooting, page 30
