Burner Flame Adjustments
WARNING: To avoid property damage or personal injury, allow the
fireplace ample time to cool before making any adjustments.
Burner flame appearance and characteristics are affected by
altitude, fuel quality, venting configuration, and other factors. After
installation, this appliance may need additional adjustments to
achieve optimum flame appearance and visual aesthetics.
10.2.1
Burner Venturi
WARNING: VENTURI ADJUSTMENT MUST BE DONE BY A QUALIFIED
SERVICE TECHNICIAN.
When this appliance is first lit, the burner flames will appear blue.
During the first 15 minutes of operation, flame appearance will
gradually turn to the desired yellow appearance. If the flames remain
blue, or become dark orange with evidence of sooting (black tips),
adjustment of the air shutter opening may be necessary.
Regardless of venturi orientation, closing the air shutter will achieve a
desired yellow flame, but may produce soot on the glass. Opening the
air shutter will cause a short, blue flame that may lift off the burner.
Slight adjustments to the venturi opening will create dramatic results.
Adjust at slight increments until desired look is achieved.
NOTE: If soot is present on the logs, check log placement (section
7.3
on page 29) before adjustment.
