INSPECTING BURNERS
Check pilot ame pattern and burner ame
patterns often.
Figure 30 shows a correct pilot ame pattern.
Figure 31 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 31
• turn replace off (see To Turn Off Gas to Appli-
ance, page 20 for Manual-Controlled Models
or page 21 for Remote-Ready Models)
• see Troubleshooting, page 31
Note: The correct pilot ame on natural gas
units will have a slight curve, but ame should
be blue and have no yellow or orange color.

Figure 32, shows a correct burner ame pat-
tern. Figure 33, 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 33
• turn replace off (see To Turn Off Gas to Appli-
ance, page 20 for Manual-Controlled Models
or page 21 for Remote-Ready Models)
• see Troubleshooting, page 25
