BURNER FLAME ADJUSTMENTS

WARNING::
• TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY,
ALLOW AMPLE TIME TO COOL BEFORE MAKING ANY
ADJUSTMENTS.
• VENTURI ADJUSTMENT MUST BE DONE BY A
QUALIFIED SERVICE TECHNICIAN.
Burner flame appearance and characteristics are affected
by altitude, fuel quality, venting configuration, and other
factors. After installation, additional adjustments may be
required to achieve optimum flame appearance and visual
aesthetics.

GAS FLAME ADJUSTMENT

During the initial installation, the air shutter opening should
be checked to be certain that the shutter is set correctly
as specified below. Adjustments should only be made by
a qualified installer. NOTE: For altitudes above 5,000 ft.,
some variations may be required.

OPERATING INSTRUCTIONS
Be sure burner and logs are properly installed. After burner
has been properly installed and operated for 2-3 hours,
small additional adjustments to the air shutter may be
necessary for final flame appearance. These small shutter
adjustments can be made by the following procedure.
NOTE: Very small changes in shutter settings make major
changes in flame appearance.
1. The air shutter control is located below the cover panel
at the right center of the appliance next to the valve
assembly.
2. If flame is too "blue," push the air shutter control in
(open) in small 1/8" increments until flame turns desired
realistic "orange" color.
3. If flame is too "orange" or is causing sooting on
viewing glass, pull the air shutter control out (close) in
approximately 1/8" increments until sooting stops.
TRY EACH NEW SHUTTER SETTING APPROXIMATELY
1 HOUR BEFORE MAKING ADDITIONAL CHANGES.
CHANGES IN BURNER FLAME CAN BE MADE BY RE-
ARRANGING THE MEDIA.
