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 Flame Height.
Specifically, if the flame is lick-
ing the top Baffle Brick, open
this damper. In most installa-
tions, the Primary Air Intake
Damper adjustment will suffice.
However, if the vent system
restricts air flow and the flames
appear too tall and lick the baf-
fle brick completely, you may
choose to open the Secondary
Air Intake Damper to reduce the
flame height. This feature will
be of the most use in LPG appli-
cations.
To adjust, use a 3/8” Open End
Wrench to loosen the securing
hex nut 2 turns ONLY. Use
Glass Latch Tool to Slide
Damper Bracket to the right
towards “CLOSED” or to the
Left towards “OPEN”.
