2. The restrictor sits inside the 5” diameter collar in
the bead area. Using a needle-nose pliers, insert
the tips of the pliers into the two holes in the restric-
tor plate. Squeeze the pliers to flex the plate. The
edges of the plate will need to overlap each other.
Insert the plate into the 5” collar from inside the fire-
box. Release the pliers, the plate will expand into
the bead (groove) inside the collar. Make sure the
plate is fully in the groove so the restrictor cannot
fall out (see Figure 9).
