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
a
Loosen (or remove) the
screw and locking tab
under the stove top.
b
Use both hands to pull the
stove top forward, rotate it up,
then lift it off the stove.

horizontal terminations and
to the top of the termination
on vertical terminations.
