INSTALL HOUSING & DUCT

1. Mount housing

2. Mount housing to joist or I-joist. Use a pliers to bend housing TABS out to 900. Hold housing in place so that the housing tabs contact the bottom of the joist. The housing mounts with four (4) screws or nails. Screw or nail housing to joist through lowest holes in each mounting flange, then through highest holes. NOTE: Mounting to I-JOIST (shown) requires use of SPACERS (included) between the highest hole of each mounting flange and the I-joist.

3. Mount housing anywhere between trusses, joists, or I-joists using hanger bars. Sliding hanger bars are provided to allow for accurate posi-tioning of housing anywhere between framing. They can be used on all types of framing (I-joist, standard joist, and truss construction) and span up to 24”.
   Attach the MOUNTING CHANNELS to the housing using the SCREWS supplied. Make sure TABS face “up” as shown. Use the set of channel mounting holes (marked “STD”) to mount the housing flush with the bottom of the drywall. Use the other set of holes (not marked) to mount the housing flush with the top of the drywall.
   Extend HANGER BARS to the width of the framing.
   Hold ventilator in place with the hanger bar tabs wrapping around the BOTTOM EDGE OF THE FRAMING.
   NAIL ventilator to framing or fasten with screws (not provided) through HOLES near nails.
   To ensure a noise-free mount: Secure hanger bars together with SCREWS or use a pliers to crimp mounting channels tightly around hanger bars.

4. Attach damper/duct connector. Snap damper /duct connector onto housing. Make sure con-nector is flush with top of housing and damper flap falls closed.

5. Install 6- inch round duct-work. Connect 6-inch round ductwork to damper / duct connector. Run ductwork to a roof cap or wall cap. Tape all ductwork con- nections to make them secure and air tight.
