How To Install A Range Hood Vent Through The Wall

Installation of a range hood vent can require digging a new pipe hole through a wall, which might also demand new wiring and fixtures, whereas reusing old ones could be easier.

To set up a range hood vent through the wall, you’ll first need to drill through the wall with a hole saw. Then, you may either use a hammer to get through the external walls.


Before installing the exterior hood cover, you must join the vent parts with aluminum tape and protect it to the hood collar. After connecting the vent pipe from the hood, normally screw the outer hood cap to the wall and apply silicone caulking to block air and water leakages.

  • Drill machine
  • Hole saw bit (6 inches)
  • Wet/dry vacuum
  • Oscillating multi-tool
  • Drill bit (¼ inch)
  • Angle grinder
  • Caulk gun
  • Wire stripper
  • Measuring tape
  • Screwdriver, Wrench
  • Wall cap
  • Safety goggles and gloves
  • Pencil

  • Decide where you need your range hood to vent.
  • Install your ductwork in the most straightforward, spacious path to the exterior wall.
  • Cut a hole 1-2 inches relatively larger than your ductwork in the position where you’ll set up the duct from your hood.
  • Join the range hood to the ductwork.
  • Affix a wall or roof lid to the outside wall or roof.
  • Clean everything inside the duct regularly to remove grease and other debris that could catch fire.

1. Cover the top duct hole with the supplier cover or lid so that only the rear duct hole will be open.

2. Position the cap where it’ll be installed and use a marker pen to mark the stoppage and pipework coordinates.

3. Holes are drilled across each corner of your structure, cutting from hole to hole with a hole shaft. After that, make a hole with the very same dimensions as the illustration for the stoppage and thread your cord through it.

4. To make a hole in the house’s exterior, drill the outer edges from within so that the outside hole lines up with the inside hole. Then, an oscillating cutting machine, split from hole to hole externally.

5. If the outer layer has a solid surface, use a precast instrument to bore the outer edges from within, followed by a connected pre-drilled hole externally. Next, use a masonry hammer to berate between holes until its center falls away.

6. Move back to the kitchen and insert a cable clamp into the hood’s knockout hole. Further, with the help of a certain person, control the cap in its state of rest.

Transmit the electrical cable through the clamp before screwing the hood beneath the cabinet.

7. The very next thing is to put in your ductwork. Put the pipework into the exterior cap (an outer nozzle cap for ductwork), then secure the wall lid to the wall surface (for a masonry wall, use screw anchors).

If required, use your steel clippers to shorten the air circulation length, but be cautious not to reduce excessively. Also, ensure that the hood compensator moves freely and is not interrupted.

8. To safeguard the wall cover from condensation, put a small amount of outer adhesive sealant around that.

9. Try replacing the light cover, fan, and filter. Next, connect the black and white wires to a ground screw and the green or copper wires. After concealing the wire connections with wire nuts, cover all the wirings with the electrical housing cover. Finally, re-connect the power and double-check everything.

To appropriately install range hood vent ductwork, begin by locating the vent area on the wall in your kitchen.

If you use a massive vent, ensure it’s at least 2 inches apart from any electrical boxes or fixtures attached to the interior wall cap.

Doing so will safeguard you against electrical shocks. Once the holes for venting and electrical components have been cut, the next process is to set up the fan hood and connect the electrical supply from within your home, if required, with the additional help of an electrician.

  1. The first step in appropriately installing a range hood is to ensure that the damper is coordinated with the exhaust vent’s entrance.
  • Draw out the bottom of the outside black slide and examine where it restricts access above or to either side. You want a point when there’s no doubt about whether or not it will completely limit access to your air filtration source.
  • Now, after you know which direction your damper should just go, protect it in an area with screws and 14-inch-wide wire tape. Check that they are firmly attached.
  • Plug in the power source to the electrical wire cables. Attach the multiple cords together by connecting them to the wire plug and then to the black cord wire.
  • The ground connector should be attached to the copper grounding. In the final phase, the fan filter is placed in the households.
  • Though air temperature increases, it is advantageous if conceivable to complain upwards throughout the ceiling. However, this is not necessary. If you can’t vent directly above your hood, vent through a side wall.
  • To keep your duct system productive, use the properly sized duct. The Airflow of your kitchen hood defines the dimensions of your vents.
  • A surface or ceiling cap installed somewhere at the side of your ventilation run will keep dust particles out. Back-drafting is also prevented sometimes when the wind hits your vents.

To prevent unwanted overtightening, specialists advise feeding wires through a hole wider than their diameter. Find a great consultant to install your ductwork to ensure a safe installation.
