How to Install a Dryer Vent

1
CUT THE VENT HOOD OPENING

  • Locate the shortest route for the duct exit.
  • Measure the path to determine the amount of duct needed. Use no more than 25 feet of 4-inch duct; subtract 5 feet for every 90-degree turn and 2.5 feet for each 45-degree turn.
  • Measure the location of your dryer vent exit and mark a circle where the opening will be in the interior of your home. For basement installation, the vent should be a minimum of 12 inches above the ground.
  • Drill a test hole in the center of the marked circle.
  • Check inside and outside to be sure there isn’t anything blocking the intended dryer duct installation spot. Plug the hole and re-drill if necessary.
  • If you are installing a dryer vent through a finished wall, remove a small section and check to be sure you won’t be cutting through any wiring, plumbing or ductwork.
  • Use a 4 ¼-inch hole saw to cut the hood opening.
  • If cutting through stucco or brick, use a hammer drill and a 1/4-inch masonry bit to create both the pilot hole and to cut out the vent hole.
  • For masonry, drill closely-spaced holes around the circumference of circle marking the opening. Then chip the masonry away with a chisel.


Tip: The three most typical clothes dryer venting options are: dryer seated on the basement floor with duct running up block wall and out joist; dryer seated on slab with duct extended straight out of the back; and dryer in an interior room with duct exiting out through the roof. Position the dryer along an exterior wall to keep the vent as short as possible.

  • Insert the duct pipe through the hole.
  • Attach the dryer vent hood to the siding with wood screws.
  • Caulk around the edges of the hood to seal.

CONNECT TO THE HOOD DUCT

  • Depending on the location of your vent, you may require an elbow to connect to the hood duct. You may have one or two elbows back-to-back to complete the run.
  • Attach the rigid duct lengths to the elbow.


Safety: When cutting rigid dryer ducting, wear leather gloves to protect your hands. The duct metal is extremely sharp and even light contact with an edge can cause injury.

SECURE THE DUCT

  • Attach straps to support the dryer duct.
  • Apply foil tape around the joints to seal them and help support the duct.

  • Insert an elbow over the dryer vent outlet.
  • Connect the rigid duct pipe to the elbow and secure the seam with foil tape.
  • Slide the dryer back into place and level using a carpenter's or bubble level.
  • Adjust the dryer legs and lock into place by tightening the locknut against the dryer.
