INSPECTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 33
shows a correct pilot flame pattern.
Figure 34
shows an
incorrect pilot flame pattern. The incorrect pilot flame is not touching
the thermocouple. This will cause the thermocouple to cool. When
the thermocouple cools, the heater will shut down.
If pilot flame pattern is incorrect, as shown in
Figure 34
.
• turn heater off (see To Turn Off Gas to Appliance,
Page 20
• see Troubleshooting,
Page 24
NOTE:
The pilot flame on natural gas units will have a slight curve,
but flame 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 fitting 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 flame holes with the fireplace running.
Some burner flame holes may become blocked by debris or rust,
with no flame present. If so, turn off fireplace and let cool. Remove
blockage. Blocked burner flame holes will create soot.
BURNER FLAME PATTERN
WARNING: If yellow tipping occurs, your fireplace
could produce increased levels of carbon monoxide.
NOTICE: Do not mistake orange flames with yellow
tipping. Dirt or other fine particles enter the fireplace
and burn causing brief patches of orange flame.
Burner flames will be steady, not lifting or floating—a bright yellow
burner flame that will be blue next to the burner. Flame patterns will
be different from unit to unit and will vary depending on installation
type and weather conditions. This can be dangerous. Inspect flames
after installation to ensure proper installation and performance.
If burner flame pattern differs from that described:
• turn fireplace off
(see To Turn Off Gas to Appliance,

)
• see Troubleshooting,
