Restrictor Plate
The restrictor plate is used to control excess draft if
necessary. Controlling the draft also changes the
aesthetics of the flame. The restrictor plate has an
unlimited range of settings (s
ee Figures 22 & 23)
.
The adjustment point is on the top, center of the
firebox, accessible with the top casting removed.
Restrictor Plate Position
The restrictor plate is factory set in the fully opened
position for shipping. This ensures proper flames for
a wide variety of vent configurations and efficiency.
The restrictor consists of a sliding plate just below
the venting starter collar on the top rear of the
firebox. Depending on your vent configuration, you
may need to adjust the restrictor plate position to
reduce draft.
Restrictor Plate Adjustment
Loosen the screw and position the restrictor plate in
the desired location. Tighten the screw to lock in
place.
