20. If the air restrictor ring is required, first determine the
number of tabs that must be bent open. Before
bending any tabs, align the mounting holes in the ring
over the four pilot holes on the back of the fireplace.
When selecting the tabs to bend, it is important to
maintain the most symmetrical pattern possible. The
first tabs bent must be opposite each other and
oriented horizontally. If only one tab is specified,
orient the ring over the pilot holes so the split tabs are
oriented horizontally and bend up two opposing half-
tabs. Additional tabs should be evenly spaced relative
to the first two. With the appropriate tabs bent, re-
align the mounting holes in over the pilot holes
keeping the proper orientation AND with the bent tabs
facing away from the fireplace body.
21. Place the vent starter pipe gasket on the back of the
fireplace aligning the holes in the gasket with the pilot
holes on the rear of the fireplace.
22. Align the inner pipe of the vent starter pipe with the
exhaust outlet pipe on the fireplace. The vent pipe will
fit tightly over the fireplace pipe. Gently push the
starter pipe on to the fireplace pipe until the outer pipe
flange makes contact with the vent pipe gasket. Be
sure that the holes in the starter pipe flange align with
the gasket and pilot holes. When the flange contacts
the gasket, install the four fasteners provided with the
starter pipe.
