A vent restrictor plate adjusts the flow rate of
exhaust gases if necessary. This ensures proper
flame characteristics and efficiency for the wide
variety of vent configurations. Controlling the draft
also changes the aesthetics of the flame. The
restrictor plate consists of a rotating shutter in the
flue connector. This shutter is attached to a rod
that protrudes through the back of the pipe. This rod
has a lock nut attached. On the very end of the rod
is an indicator slot. This slot shows the relative
position of the restrictor shutter. If the slot is
pointing up and down (12+ 6 o’clock position) the
restrictor is open. If it is pointing left and right (9+3
o’clock, the restrictor is in the closed position. The
restrictor plate has unlimited settings. Depending
on the vent configuration, you may be required to
adjust the restrictor plate position (see Figure 8).
Once the desired position is reached, use a 7/16”
wrench to lock down the hex nut.
