In this video, This Old House general contractor Tom Silva installs a new range vent hood.
1. Use a 6-inch-diameter hole saw to cut a hole through the interior wall surface, directly above the range. Collect the dust with wet/dry vacuum while cutting the hole.
2. If the hole saw can't cut through the interior wall in one pass, stop cutting, remove the plaster from the hole, and continue drilling.
3. If necessary, use a multi-tool to cut wood lath from the 6-inch hole.
4. Replace the hole saw with a ¼-inch-diameter bit and drill through the backside of the wall sheathing to the outdoors.
5. From outside, use the 6-inch hole saw to cut through the siding and wall sheathing.
6. Make a mounting plate by cutting 6-inch-diameter hole through a piece of PVC trim.
7. Hold the PVC plate against the house siding, and trace around it with a pencil.
8. Use an angle grinder to cut the siding along the pencil lines.
9. Apply bead of silicone adhesive around the hole in wall. Press the PVC mounting plate tight to the wall, and secure with screws.
10. Use duct tape to attach a 6-inch-diameter elbow to the vent cap.
11. From outside, slide the vent cap into the hole and secure it to the mounting plate with self-tapping screws.
12. From inside the kitchen, slide an elbow through hole and onto vent cap elbow. Secure with duct tape.
13. Screw the vent-hood mounting brackets to kitchen wall; be sure to drive the screws into wall studs.
14. Slide the vent hood into the brackets and secure with screws driven into wall studs.
