Inspecting Burners - Superior Fireplaces VRL4543ZMN Installation And Operation Instructions Manual

Check pilot flame pattern and burner flame
patterns often.
PILOT FLAME PATTERN
Figure 44 shows a correct pilot flame pattern.
Figure 45 shows an incorrect pilot flame pat-
tern. The incorrect pilot flame is not properly
heating the sensing electrode and the heater
will shut down.
If pilot flame pattern is incorrect, as shown
in Figure 45
• turn heater off (see To Turn Off Gas to Ap-
pliance, page 21)
• see Troubleshooting, page 27
Note: The pilot flame on a 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 block-
age 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 de-
scribed:
• turn fireplace off (see To Turn Off Gas to
Appliance, page 21)
• see Troubleshooting, page 27
