Air Shutter Setting - Majestic Quartz Series Installation Manual

E. Air Shutter Setting
WARNING! Risk of Explosion or Delayed Ignition!
Improperly adjusted air shutter could cause soot buildup.
NOTICE: If sooting occurs, provide more air by opening
the air shutter.
Air shutter settings should be adjusted by a qualified ser-
vice technician at the time of installation. The air shut-
ter is set at the factory for a typical horizontal termination
through a 2 X 6 wall:
Top Vent: 90 degree elbow off top with 12 inches horizontal.
Rear Vent: 12 inches horizontal.
Adjust air shutter for different vent runs. See Figure 9.1.
• Loosen the wing nut.
• Push the air handle in to close the air shutter.
• Pull the air handle out to open the air shutter.
• Tighten the wing nut.
Air Shutter Settings
QUARTZPLA36IN (NG)
QUARTZPLA36IL (PROPANE)
The air shutter settings listed above were set based on an
appliance that was vented off the top with one 90 degree
elbow and the maximum horizontal vent run permitted; this
vent configuration is considered to be a more restrictive
vent configuration. For less restrictive venting, such as
short horizontally terminating or a vertically terminating
appliance, the shutter may be adjusted to a more "closed"
position.
Natural Gas (NG) installations:
As a general rule, it is acceptable to reduce the shutter
opening to adjust for short horizontally terminating or
vertically terminating vent configurations prior to the initial
fire up.
Propane (P) installations
• It is recommended that the air shutter on propane
appliances remain at the setting preset at the factory.
Air Shutter Adjustment
The air shutter may be adjusted by locating and loosening
the wing nut shown in Figure 9.1. Push/Slide the wing
nut toward the back of the appliance to close the shutter.
Pull/Slide the wing nut toward the front of the appliance to
open the air shutter.

Shutter Setting Verification / Flame Appearance
• After 15 minutes, the flames will be a yellow/blue mix.
The front flames may be blue at this time.
• After 30 minutes, the flames should be yellow with
some blue flames near the burner ports.
• After 1 hour, the flame will be at is maximum maturity.
NOTICE: Flames should not appear orange or stretch to
the top refractory. If flames are dark orange with dark,
smoky tips, provide more primary air to the burner by
opening the air shutter accordingly.
Note: Visually, a propane flame may differ from a
natural gas flame. This is due to the different chemical
compositions that make up both fuel types. In general,
the propane (P) flames may be a little shorter and much
brighter than a natural gas (NG) flame.
