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 describe which position the vent restrictor must be in.
To Adjust the Restrictor:
Withe the fireplace cool, use the
bent rod included in the owner’s
pack to adjust the plate.
