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

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

between starter stubs and flex inner surface.

equally spaced radial locations and above the hose clamp to stop hose
clamp from sliding off.
