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.
With the face removed and
the fireplace cool, reach
above the firebox.
