Approved Vent Configurations

Restrictor Position

• A restrictor is built into the appliance to control the flow rate of exhaust gases. This ensures proper
flames for the wide variety of vent configurations. Depending upon the vent configuration, you may be
required to adjust the restrictor position. The charts for approved vent configurations describe which
position the vent restrictor must be in.
To Access the Restrictor
Lift the stove top off the
stove and place it aside.

Measuring Vent Lengths

Vent Height is calculated to
the top of the vent on
horizontal terminations and
to the top of the termination
on vertical terminations.
