21. An additional storm collar band is provided in kit that may be
used as an attic insulation shield. The collar can be installed

cap to the top of the hard vent pipe assembly. Mate up the
ue and outer telescopes with the hard pipe assembly, then
secure by installing a minimum of two sheet metal screws into
the overlapped anges of the cap and pipe.
