AIR RESTRICTOR ADJUSTMENT
The fireplace is equipped with a restrictor plate that is located inside the top chamber of the fireplace. Depending upon the
vent configuration, you may be required to adjust the restrictor position
1. Remove glass frame.
See Glass Frame Removal, page 31.
2. Using a Phillips screw driver, loosen the screw that secures the air restrictor. Do not back the screw all the way out.
3. Slide the baffle on top of the restrictor plate such that it blocks a percentage of the grill opening. Refer to the chart below
for recommended settings.
Venting Height (feet)
% of Grill Opening
8 to 20
100% (Factory Setting)
20 to 30
50%
30 to 40
0%
Note: All the settings above are based on the testing at the factory and provided as a guide for startup.
On certain applications, adding a restrictor disc will help to achieve flame aesthetics.
