NSULATED FLEXIBLE DUCTS
Use the following procedure to connect the insulated flexible duct to the ports (exhaust to outside and fresh air from outside).

Pull back the insulation to expose the flexible duct and place it over inner port ring.

Install good quality aluminum duct tape on flexible duct to prevent potential water leakage from duct.

Attach the flexible duct to the port using tie wrap.

Pull the insulation over the joint and tuck it between the inner and outer rings of the double collar.
 
Pull down the vapor barrier (shaded part in illustrations below) over the outer ring to cover it completely. Fasten the vapor barrier
in place using the port strap (included in parts bag). To do so, insert one collar pin through vapor barrier and first strap hole, then
insert the other collar pin through vapor barrier and center strap hole and close the loop by inserting the first collar pin in the last
strap hole.
Make sure that the vapor barrier on the insulated ducts does not tear during installation to avoid condensation
within the ducts.
