There is a vent restriction plate that adjusts the flow
rate of exhaust gases. 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 restriction
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 restriction
plate has unlimited settings. Depending on the vent
configuration, you may be required to adjust the
restriction plate position. Once the desired position
is reached, use a 7/16” wrench to lock down the
hex nut.
