INSPECTING BURNERS
Check pilot ame pattern and burner ame
patterns often.

Figure 33 shows a correct pilot ame pattern.
Figure 34 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 34
•
turn replace off (see To Turn Off Gas to Appli-
ance, page 19 for Thermostat-Controlled Mod-
els or page 21 for Remote-Ready Models)
• 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.

Figure 35 shows a correct burner ame pat-
tern. Figure 36 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 36
•
turn replace off (see To Turn Off Gas to Appli-
ance, page 19 for Thermostat-Controlled Mod-
els or page 21 for Remote-Ready Models)
• see Troubleshooting, page 25

The primary air inlet holes allow the proper
amount of air to mix with the gas. This pro-
vides a clean burning flame. Keep these
holes clear of dust, dirt, lint and pet hair.
Clean these air inlet holes prior to each
heating season. Blocked air holes will create
soot. We recommend that you clean the unit
every three months during operation and
have replace inspected yearly by a qualied
service person.
