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 important to understand
the functions of the two dampers prior to adjusting 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 installation 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 installation will yield a different air-flow characteristic and may need some slight ad-
justment 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 applications.
To adjust, use a 3/8” Open End
Wrench to loosen the securing
hex nut 2 turns ONLY. Use
Glass Latch Tool to Slide Dam-
per Bracket to the right towards
“CLOSED” or to the Left to-
wards “OPEN”.
