An approved chimney liner and rain cap must be used. A throat connector or flashing
must
be installed to
ensure a tight seal, top performance, safety and efficiency. Carefully follow the manufacturer’s instructions
that accompany the chimney liner kit. Use double walled aluminum flex vent (3” flex conversion piece and
4”x 6 5/8” cap) from any of the following approved products; Simpson Dura-Vent (Direct Vent GS) or (ICC
Excel Direct). If necessary, remove the vent collar plate from the top of the insert and connect it securely
to the liner with sheet metal screws.
Check for any tears in the liner at this point. IMPORTANT: The screws that hold the vent collar plate in its
approved position must be installed.
