An approved chimney liner and rain cap must be used. A throat connector or ashing must be installed to
ensure a tight seal, top performance, safety and efciency. Carefully follow the manufacturer’s instructions
that accompany the chimney liner kit. Use double walled aluminum ex vent (3” ex conversion piece and
4”x 6 5/8” cap) from any of the following approved products; Simpson Dura-Vent (Direct Vent GS) or (ICC

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.
