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.
NOTE: Vent location changes based
upon restrictor position. Position # 1 is
shown to the right. Each restrictor
position moves the vent location forward
(toward the fireplace opening)
approximately 1/4".
