Approved Vent Configurations
Restrictor Position
¥ A vent restrictor is built
into the appliance to
control the flow rate of
exhaust gases. This
ensures proper flames
for the wide variety of
vent configurations. The
restrictor consists of a
butterfly valve in the air
inlet and an adjustment
plate with index holes
used to hold the valve in
a fixed position.
Depending upon the
vent configuration, you
may be required to adjust
the restrictor position.
The charts for approved
vent configurations
describe which position
the vent restrictor must
be in.
To Adjust the Restrictor:

counter-clockwise until the correct
index hole is above the pivot point.
Insert the screw into the correct
index hole and tighten.
