Approved Vent Configurations
Restrictor Position
•
A vent restrictor is built
into the appliance to
adjust the flow rate of
exhaust gases. This
ensures proper
combustion for all vent
configurations.
Depending upon the
vent configuration, you
may be required to
adjust the restrictor
position. The charts for
acceptable vent
configurations detail the
correct vent restrictor
position.
Determine a restrictor position (see the charts
under "Approved Vent Configurations")
Remove the screw with a 1/4" magnetic nutdriver.
Rotate the adjustment plate until the correct index hole is
below the pivot point (the pivot point is slotted, use a slotted
screwdriver to turn the adjustment plate)
