attach the 4” exhaust flex and the 3” air intake flex to the
unit top vent adapter using hose clamps and sheet metal
screws

At the fireplace cavity attach 4” flex vent to 4” starter
collar on sliding vent adapter.
2.
Secure 4” vent flex to 4” starter collar employing one 4”
hose clamp and a ratchet. Position hose clamp close to
the flashing plate. Compress the flex as much as
