- 1). Locate where you would like your dryer vent to penetrate the exterior wall of your home. Drill a 1/4-inch hole from the inside out to make a visible reference point on the outside of your home.
- 2). Go outside and locate the hole. If it's in the correct location, cut a 4 1/4-inch hole with your hole saw.
- 3). Insert the pipe stub of the vent hood into the hole and push the vent hood in until its tight against your home.
- 4). Screw it on to your home with exterior wood screws. Apply a bead of silicone caulk around the vent hood to make it weather tight.
- 5). Go inside and install the sheet metal ducting from your dryer to the pipe stub. You should notice your pipe stub sticking through the exterior wall in the ceiling joist space. Connect the ducting together by inserting the crimped end of one piece into the crimped end of another piece. Secure the connection by wrapping 3-inch foil aluminum tape around the connection.
- 6). Cut pipe lengths down as necessary with your snips to allow for shorter pieces. Crimp one end of the cut joint with your pipe crimper so it can be connected into the duct system. Use elbows where turns are needed.
