INSPECTING BURNERS
Check pilot ame pattern and burner ame pat-
terns often.
PILOT FLAME PATTERN
Figure 35 shows a correct pilot ame pattern.
Figure 36 shows an incorrect pilot ame pattern.
The incorrect pilot ame is not properly heating
the thermocouple. When the thermocouple cools,
the heater will shut down.
If pilot ame pattern is incorrect, as shown in
Figure 36
• turn heater off (see To Turn Off Gas to Appli-
ance, page 20)
• see Troubleshooting, page 24
Note: The pilot ame on a natural gas units will
have a slight curve, but ame should be blue and
have no yellow or orange color.

BURNER PRIMARY AIR HOLES
Air is drawn into the burner through the holes in
the tting at the burner entrance. These holes may
become blocked with dust or lint. Periodically
inspect these holes for any blockage and clean if
needed. Blocked air holes will create soot.
MAIN BURNER
Periodically inspect all burner ame holes with the
replace running. All slotted burner ame holes
should be open with yellow ame present. All round
burner ame holes should be open with a small blue
ame present. Some burner ame holes may become
blocked by debris or rust, with no ame present. If
so, turn off replace and let cool. Remove blockage.
Blocked burner ame holes will create soot.
BURNER FLAME PATTERN
WARNING: If yellow tipping
occurs, your replace could
produce increased levels of
carbon monoxide.
NOTICE: Do not mistake orange
ames with yellow tipping. Dirt
or other ne particles enter the
replace and burn causing brief
patches of orange ame.
Figure 37 shows a correct burner ame pattern. Fig-
ure 38 shows an incorrect burner ame pattern. The
incorrect burner ame pattern shows the ame higher
consistently higher than 1 inch above the logs.
If burner ame pattern is incorrect, as shown in
Figure 38
• turn heater off (see To Turn Off Gas To Appli-
ance, page 20)
• see Troubleshooting, page 24
