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 a
large range of unlimited settings (s
ee Figures 19 &
20)
. The adjustment point is on the left side of the
firebox (from front).
Restrictor Plate Position
The restrictor plate is factory set in the fully closed
position for shipping. Leave in the closed position
until you install the Heat Wave baffle
– then set to
the fully opened position. This ensures proper
flames for a wide variety of vent configurations and
efficiency. The restrictor plate consists of a rotating
flap in front of the firebox exhaust port behind the
ceramic Heat Wave baffle plate. 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.
