Vent Location
• 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.
