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. Refer to 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 to block a percentage of the grille opening.  Refer 

to the chart below for recommended settings.

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.
