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.
