3. Make the wiring connections.

Locate the 11" (27.9 cm) dia. hole between rafters.

Build a sloping base that will mount the exterior blower at a minimum pitch of

2-1/2" (6.4 cm). Weatherproof the base as required.

Locate the base so that the exterior blower's vent aligns with the 11" (27.9 cm) dia. hole and the blower sits evenly on the base with no gaps.

NOTE: Make sure that the discharge end of the exterior blower faces away from the direction of prevailing winds.

Use dimensions from either FIGURE 1 or 2 (Page 3) to locate the 1-1/4"

(3.0 cm) dia. wiring hole.

6. Remove roofing nails from the upper two-thirds of the shingles to allow the back flashing sheet on the exterior blower housing to fit under them.

7. Center the exterior blower collar in the 11" (27.9 cm) diameter hole, making sure that the 1-1/4" (or 3.0 cm) diameter electrical wiring hole lines up with the hole in the wiring box.

8. Attach the exterior blower to roof or frame using screws appropriate for your installation. All four holes in the back panel must be filled to prevent moisture that may get inside the remote blower housing from leaking into the home.

Electrical Shock Hazard

Disconnect power before servicing.

Connect the ground wire to green ground screw in wiring box.

Failure to do so can result in death or electrical shock.

1. Connect the vent work to the exterior blower’s black plastic vent collar and seal connection securely with duct tape.

2. Remove the wiring box cover and pull the 120-volt power supply cable through the strain relief.

(See FIGURE 3 and wiring diagram.)

•Using twist-on connectors:

•Connect white wires.

•Connect black wires.

•Connect the green power supply wire to the unused green ground screw.

•Securely tighten strain relief screws.

4. Replace the wiring box cover and securely tighten the screws. Make sure that wires are not pinched under the cover.

5. Reinstall blower cover and tighten screws securely.

6. Connect the vent work to the hood.

7. Follow the Installation Instructions that came with the hood installed and complete the wiring connections.

8. Turn on the power. Follow the instructions in the “Check Operation” section of the Installation Instructions that came with the hood installed and make sure blower operates properly. Check that the damper, if used, operates freely.
