Press a stud finder against an exterior wall to locate the studs behind the dryer. Follow the instructions included with the stud finder for proper operation. Mark the location of the studs with a pencil. Most electronic stud finders will also alert you to electrical lines. The location must not generate any indications of electrical lines.
Press the round tube of the dryer vent kit against the wall and mark the diameter of the circle created onto the wall. Position the kit so that it falls between two studs and sits approximately 1 foot off the floor. The exterior of the wall should also be approximately 1 foot or more off the exterior ground.
Hammer a small hole into the center of the circle marking. Look inside the hole for any electrical wires or pipes that may be running behind the wall. Proceed if there are no wires or pipes. Identify an alternate location if any wires or pipes are present.
Insert the metal cutting blade of a reciprocating saw into the hole. Cut the interior wall out with the saw. Pull out any insulation in the way of the exterior wall.
Press the tube for the kit into the hole created so that the tube presses against the exterior wall. Mark the diameter of the circle with a pencil.
Drill four holes through the exterior wall from inside the hole created in Step 4. The holes need to be flush with the marks made in Step 5 so that a basic square design is created by the holes within the diameter of the circle.
Press the tube against the exterior wall from the outside so that the four holes are visible within the tube. Mark the diameter of the tube so that the markings intersect the exterior sides of the four holes, creating a circle that matches the circle on the opposite wall. Cut the circle out with a reciprocating saw.

- The two holes cut into the wall do need to be level but are not required to be the precise size. Dryer vent kits include a wall-mounted face that will cover any imperfections made when cutting the holes. The important aspect is that the holes are level so that the inside wall-mounted face can be attached to the exterior face.
