1. Once you have determined the location for both the fan and damper grille, use the supplied square
template to cut out your roofing and ceiling material for the supplied Plenum Flash Mount and
damper grille.
2. Secure the Flash Mount to the roof. Finish caulking around the Flash Mount and flash it into the roof to
make a nice seal. Take the plenum box and slide the Flash Mount lip into the plenum box.
3. Make sure the plenum box sits flush to the roof. Using roofing nails, fasten the plenum box to the roof
using the six tabs located around the plenum box.

4. Position the fan on it's side allowing the RF Control Hub to hang in the circle fan hole in the plenum box.
Remove the power cord and RF Control Hub from the fan flex. Run the fan flex into the junction box on
the bottom floor of the plenum box. Remove junction box plate cover and tie wires together. Re-install the
plate cover.
5. Lifting the fan unit up at an angle, apply weatherproof caulking to the bottom side of the fan unit. This will
help keep the fan in place and will seal nice and tight.
6. Position the fan over the circle fan hole in the plenum box. Using the supplied self-tapping screws with
rubber-bonded washers, attach the fan unit to the plenum box. Be sure to caulk around the screw head.
IMPORTANT: If you have drywall on your ceiling, use the supplied template to cut out your grille hole.

If you have open ceiling rafters with no drywall, you will need to frame in the grille. (See Figure 2.5D)
7. Run your electrical piping or seal tight flex into the half inch knockout in the plenum box. From inside the
home, mount the RF Control Hub into the half inch knockout in the plenum box. Bring your electrical wires
into the backside of the RF Control Hub (See Figure 2.5B). Slide your lock nut over the wires and thread it
onto the 1/2" flex connector to secure the RF Control Hub to the plenum box. Bring the fan wires from the
harness inside the plenum box into the RF Control Hub (See Figure 2.5C).
8. Follow the wiring instructions on page 11 to wire your RF Control Hub to the power source.
