Installation (for qualified installers only)

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.
NOTE: The vent location changes based upon restrictor position. Position # 1 is shown below. Each
restrictor position moves the vent location forward (toward the fireplace opening) approximately ¼" (7mm).
