Restrictor Position

•Intake and exhaust restrictors are built into the appliance to adjust the flow rate of intake air and exhaust gases. Depending upon the vent configuration, you may be required to adjust the restrictor positions. The charts for acceptable vent configurations detail the correct vent restrictor positions.

Exhaust Restrictor Adjustment

If the diffuser is required to be in position # 2, you may wish to adjust the diffuser while the exhaust restrictor is removed.

Loosen these four screws on the exhaust restrictor.

Slide the restrictor to the correct restrictor position (see the illustration below). The rear screws indicate restrictor position. In this example, the restrictor is set in position # 3. Tighten the screws to secure the restrictor.

NOTE: If using position 5 or 6 you will need to remove the forward screws. These screws are then re-inserted into the back holes exposed while sliding the restrictor.
