How to Install an Outdoor Dryer Vent Cap
- 1). Stand inside the house and locate the spot where you want the vent to go on the exterior wall. Ideally, it will be an unfinished basement wall so you can choose a point well clear of any studs. Drill a starter hole in the wall.
- 2). Go outside. With your pencil, draw a new mark near the hole you drilled, but adjusting it for exterior wall factors. It should be at least a foot off the ground and be centered on any lap siding.
- 3). Use your drill with the hole-saw attachment to bore out a 4-1/4-inch hole from the outside of the house, with the center bit of the hole saw on your mark.
- 4). Slide the 4-inch metal tube from the vent assembly into the hole. Press the exterior cap of the vent assembly against the wall, with the sealed end facing up and the open end facing down. Secure it with the provided screws. Caulk around the edges of the cap.
- 5). Go back inside. Caulk around the interior of the wall where the 4-inch vent tube comes in. Slide the hose from the dryer into the end of the vent tube and secure it with foil tape.
