BURNER FLAMES ADJUSTMENT- AIR INTAKE DAMPER CONTROLS
This appliance is equipped with two Air Intake Adjustment Damper
Controls: PRIMARY DAMPER and SECONDARY DAMPER. It is im-
portant to understand the functions of the two dampers prior to adjust-
ing them.
PRIMARY AIR INTAKE DAMPER
: The PRIMARY AIR INTAKE
DAMPER is located on the top of the Air Intake Pipe attachment Stub.
This Damper is factory set at 45 degrees OPEN.
This damper is manually adjustable and must be adjusted during in-
stallation of this appliance. For Vent Systems lengths less than 20
feet, leave this damper at its factory adjusted (45 degree OPEN) setting. Starting at vent system lengths of 30
feet, adjust the damper position according to the table. Note that this table is a general guideline only. Each instal-
lation will yield a different air-flow characteristic and may need some slight adjustment beyond what this table
calls for.
SECONDARY AIR INTAKE DAMPER
: The SECONDARY AIR INTAKE DAMPER is located in the convection
air cavity on top of the firebox. It is accessible through the ½” slot that is located directly above the glass frame’s
top surface. The SECONDARY AIR INTAKE DAMPER is factory adjusted to “FULLY CLOSED”. Adjust this
damper to fine tune the Rear Flame Height. Specifically, if the rear flame is licking the top Baffle Brick, open this
damper. In most installations, the Primary Air Intake Damper adjustment will suffice. However, if the vent system
restricts air flow and the rear
flames appear too tall and lick
the baffle brick completely,
you may choose to open the
Secondary Air Intake Damper
to reduce the rear flame
height. This feature will be of
the most use in LPG applica-
tions.
To adjust, use a 3/8” Open
End Wrench to loosen the se-
curing hex nut 2 turns ONLY.
Use Glass Latch Tool to Slide
Damper Bracket to the right
towards “CLOSED” or to the
Left towards “OPEN”.
