(6 mm) I.D. hose.
4. Light burner. Check manometer reading.
5. Turn burner and pilot off.
6. Disconnect manometer hose and tighten the
manifold (OUT) pressure tap by turning screw

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 ame appearance and characteristics
are affected by altitude, fuel quality, venting
conguration, and other factors. After installation,
additional adjustments may be required to achieve
optimum ame 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 specied below. Adjustments
should only be made by a qualied installer. NOTE:
For altitudes above 5,000 ft., some variations may
be required.
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 nal ame
appearance. These small shutter adjustments can
be made by the following procedure. NOTE: Very
small changes in shutter settings make major
changes in ame 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 ame is too “blue,” push the air shutter control
in (open) in small 1/8” increments until ame
turns desired realistic “orange” color.
3. If ame 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.
CAUTION:
TRY EACH NEW SHUTTER SETTING
APPROXIMATELY 1 HOUR BEFORE MAKING
ADDITIONAL CHANGES. CHANGES IN BURNER
FLAME CAN BE MADE BY RE-ARRANGING THE
MEDIA.
