The most common method for householders is to configure a range hood on an interior wall. While it may appear difficult, it is easily achievable if you have installation expertise and capabilities.

You can always contact a professional to complete the task for you. However, if you really want to do it yourself, keep in mind that the range hood requires ducts that will run along your walls. Therefore, it is critical to do it correctly to maximize its functions and features.

One technique is also known as ‘horizontal wall venting’ and requires approximately 18 inches of venting before the elbow can be installed.

Instructions You Need To Follow For A Convenient Installation

1) Take the hood off the range

  • Hold your range hood to make installation easier.
  • It is not essential to use a second filter. After that, take out the pipe.
  • Carefully remove the four-cornered pipe extension to guarantee that it is not distorted or twisted.
  • Professionals should always plan ahead of time and make absolutely sure that all of the steps are in order.

2) Choose an exact position

  • The position of an exhaust vent on the internal wall of the range hood is extremely crucial. You want to make it productive while maintaining the visual quality of the house.
  • You will need to cut a bigger hole in your wall for the ducting. Unfortunately, if the gap is too large, it is hard to correct, so give it your best shot when cutting.
  • Put a point about ⅛ inch underneath the upper end of the kitchen wall. After that, draw a line down the wall. Finally, bring your kitchen hood to an end at the bottom of this vertical line.
  • Begin by drawing a horizontal line to the right of the stovetop. Maintain a minimum distance of 30 inches between the bottom and the top.

3) Select a clear and unobstructed path

  • There should be no more than two elbows in the duct. Ventilation systems that are too large would be unable to decrease the air pollutants more effectively.
  • This is imperative to consider for a more accurate method. However, ensure that the ductwork is always at least 30 inches long to prevent the polluted air from traveling far off.
  • Ducting requires connectivity to be wrapped through the wall. The basement or roof are ideal locations for this. Before you start cutting into your wall, consult a domestic consultant.
  • Create a hole that is 2-3 inches larger than the ductwork.
  • A properly installed range hood should last for several years. While its equipment is connected, the ducting can be conveniently inserted throughout a 1- to 2-inch-wide opening.

4) Using a hole saw, cut a smooth and round hole

  • Remove all of it from the inside and operate the duct through the exterior sheathing inlet. To maintain mechanical strength, never remove a joist from the building.
  • Place the hole on the house’s exterior once it has been drilled. To insert the duct, the hole must be found in the external wall and connected to the joist bay.
  • Screw two 5 ×10 bolts into the center of your outline. Tighten the wall’s top and bottom together. Then, fill the hole with new drywall. The pipe and other materials can easily flow inside and outside the wall.

5) Attach the range hood to the ductwork

  • Even though the installation process is simple, the finer details are more difficult. However, only a transition piece is required to link the range hood to the ductwork.
  • Pass the wires through a round hole in the range hood’s crown. A clamp is a device used to toughen power cables. With the support of wire cables, you can link multiple cables together. For example, before you hold the range hood in your kitchen, connect the earth and neutral cables.
  • A 12 × 18-inch PVC sheet is suitable for connecting boxes. Using this tool, circular holes in the ducting can be simply created. Next, attach the nuts to the exhaust valve insides. Flat head bolts secure the venting machine to the installation box. There have to be at least three inches between all the screws.
  • Cut the vent’s rim before actually placing the ducting to ensure a good fit. Then, choose an external caulk to bridge the gap between the duct and its mounting box.

6) As directed, add the wall cap to your external wall

  • To finish installing, each duct’s end cap can be completed with a wall cover. The objective of this is to prevent unwanted particles out of the vent. It ensures long-term efficiency.
  • Utilizing PVC trim, you can consider making your range hood actually fit against the wall. Allows for effective placement of the wall cap on the external wall.

7) First, before using the unit, inspect it

  • Turn on the electricity inflow and ensure the range hood blower operates after venting it. Check that the cables are also in proper working order.
  • The wall cap must stretch when the blower is running. So, while waiting for the fragrance to fade, try running your range hood and see if it helps.

Important Points To Keep In Mind While Venting A Range Hood

  • Take a look at the space just above the stove. The oven must be 20-24 inches apart from the range hood. For cooktops, the required distance is wider.
  • Before actually aiming to install the device, unplug all power cables. To avoid fire hazards, turn off the kitchen’s supply of power.
  • The power supply in the power outlet where the range hood vent is wired in must be accurate. Voltage regulators for outlets and cables can be identified by inspecting their tags.
  • The warranty on the products and services you purchased cannot be withdrawn. But a damaged product can be exchanged or refunded. Please read the terms for it.
  • To enable successful ventilation, keep your ducting no longer than 40 feet long.
  • Duct insulation can help to prevent humidity and leakages.
  • Before removing an old hood or upgrading one, always turn off the electricity.
  • Make sure that the wall cap length is not too long or too short so that the overall work doesn’t really appear untidy.
  • To minimize damage to your kitchen cabinet, always take care when lowering it.


Venting your range hood through an interior wall is far more convenient than climbing your roof to install it.
