3.INSTALLATION (CONT’D)

3.7CONNECTING THE DUCTS TO THE UNIT

Insulated flexible ducts

Use the following procedure for connecting the insulated flexible ducts to the port of the unit (Exhaust air to outside and Fresh air from outside ports).

CAUTION

Make sure the balancing dampers are set to their appropriate position before connecting the ducts to the ports. See Section 3.3.

VJ0039

Pull back the insulation to expose the flexible duct.

Rigid ducts

VJ0040

Attach the flexible duct to the port using tie wrap.

VJ0043

Pull the insulation over the joint and tuck in between the inner and outer rings of the double collar.

VJ0041

Pull the vapor barrier over the insulation and over the outer ring of the double collar.

CAUTION

Make sure the vapor barrier on the

insulated ducts does not tear during installation to avoid condensation within the ducts.

VJ0042

Apply duct tape to the joint making an airtight seal.Avoid compressing the insulation when pulling the tape tightly around the joint. Compressed insulation loses its R value and causes water dripping due to condensation on the exterior surface of the duct.

CAUTION

Do not use screws to connect the rigid ducts to the ports.

Use a small length of flexible duct to connect the rigid duct to the ports in order to avoid vibration transmissions. Use tie-wraps to perform connections.

3.8INSTALLING THE TANDEM® TRANSITION KIT

Use the following procedure for connecting the insulated flexible ducts to the Tandem® transition* (Exhaust air to outside and Fresh air from outside).

NOTE: The joist opening needed to install the Tandem® tansition must be 9¾” (248 mm) minimum. Also, the maximum height of the Tandem® transition is 8¾” (222 mm). See Tandem® transition end view beside. If the joist are perpendicular to the ducts, or if the connection to the exterior hood is in a limited area, your installation will need two exterior hoods instead of one. In this case, do not use the Tandem® transition kit. See

next Section 3.9 INSTALLING 2 EXTERIOR HOODS.
