Exhaust Restrictor Position
An exhaust restrictor is built into the appliance to adjust the flow rate of exhaust gases. Depending upon the
vent configuration, you may be required to adjust the restrictor position. The charts for vent configurations
detail the correct restrictor position.
Slide the restrictor to the correct
restrictor position (see the illustration
below). Screw location indicates
restrictor position. In this example, the
restrictor is set in position # 5. Tighten
the screws to secure the restrictor.
