Find a spot on the wall where the Deflect-O dryer vent will be installed. Use a stud finder to check for wall studs or other obstructions inside the wall. Then, mark the spot by tracing around the end of the vent's pipe with a pencil. Measure the distance from a window or door so that you can find a location on the outside wall as well.
Check the outside wall for obstructions that may prevent installation of the dryer vent. If no obstructions are present, return inside and use a drill with a long bit to drill a pilot hole through the wall in the center of the mark that was made.
Use the pilot hole as a guide to cut a hole in the wall with a 4-1/4-inch hole saw. Insert the pipe end of the Deflect-O dryer vent to ensure a good fit, enlarging the hole with a reciprocating saw or larger hole saw if necessary.
Insert the Deflect-O dryer vent into the hole from the outside, attaching the vent hood to the side of the house with wood screws. Apply caulk or other weatherproofing sealant around the edges of the vent hood to prevent moisture and insects from entering the home. Apply an additional seal around the vent pipe as it exits the interior wall if a gap is visible.
Slide a portion of duct pipe or tubing over the vent pipe on the internal wall, securing it with foil tape and hose clamps. Connect the other end of the duct pipe or tubing to the dryer's exhaust pipe, making sure that it is level to prevent lint accumulation.
- Use duct elbows when using hard pipe and placing your Deflect-O vent above your dryer. Use as little duct pipe as possible while avoiding awkward angles or twists that will promote lint and dust buildup.
