Steps

1
Identify the vent location and drill a pilot hole through the wall using a 6-inch hole saw. Drill slowly and use a vacuum to collect dust as you penetrate the plaster and studs.
2
Drill a pilot hole straight through the existing hole to pinpoint the exact exit location on the exterior wall.
3
Prepare the exterior mounting surface. Cut a 6-inch hole in a PVC trim block, mark the perimeter on the siding with a pencil, and remove the necessary section of siding to inset the block. Bevel the edges of the block and siding to ensure water sheds away from the house.
4
Install the exterior hood by pushing it tightly into the PVC block and securing it with self-tapping screws driven through the metal hood and into the block.
5
Connect the duct work. Attach sections of 6-inch ducting to the exterior hood, using an elbow to transition from the exterior wall to the internal angle required for the range hood.
6
Install the interior mounting brackets and position the range hood unit. Connect the electrical wiring by matching the wire colors: connect black (hot) to black and white (neutral) to white.
7
Slide the range hood into the ceiling or mounting position and turn on the power to test that the fan is functioning correctly.

Pro Tips

  • If the fan is too noisy after installation, tighten any loose screws or bolts securing the fan motor to the mounting bracket or the hood to the wall and cabinet.

When to Call a Professional

If ductwork requires cutting through exterior walls or the roof, hire a licensed HVAC contractor.
