How to install kitchen exhaust vent through wall.

Cut a vent hole through the interior drywall or plaster with a reciprocating saw or hole saw. Venting through a roof vent or exhausting them in the attic could cause moisture problems and rot. Take all precautions to avoid studs pipes or wires while cutting and drilling. Or drill a hole and use fish tape to find structure.

In either case do not vent into the wall or the attic. The duct for your exhaust fan needs to be run to the outside of the house to remove the chance of a fire hazard. Run duct work through the attic then attach the stove vent to a roof cap. Slide the pipe into the hole.

Then flash it with the shingles that you removed prior on both sides and above the vent. Go to where the new fan is located and route the hose to the wall where the old exhaust vent hose exits through the wall. If you decide to vent through the roof go all the way out to clear air through the roof and don t just vent it into the attic. Another consideration is where to vent the hood.

The best exhaust fan venting is through smooth rigid ducts with taped joints and screwed to a special vent hood. Vent your bath and kitchen exhaust fans through the roof through a special roof hood. Using a pencil trace an outline of the circular exhaust housing. Remove the old hose from the wall fitting and attach the new hose using the vent hose tape.

Use a long bit to drill locator holes at each corner of the vent hole all the way through the exterior wall. Wear a dust mask and eye protection. Bring the wire connectors flashlight vent hose tape and screwdriver. While this can be done through the ceiling and out through the roof it s best to go through an outside wall because there s less need for waterproofing.

Install the vent and seal the underside of the vent flange with roofing grade sealant caulk. Seal between the top of the vent flange and at the bottom of the roofing shingles as well. Typically you ll secure the short length of duct to the downward facing exerior hood flange then insert the exterior hood in the hole in the wall from the outside. Go to where the ceiling access hatch is located.
