How To Vent A Range Hood On An Interior Wall (6 Easy Steps)

The range hood is an essential component of kitchen equipment. It promotes adequate air circulation and prevents filthy cabinet or countertop surfaces, so the area smells and looks fantastic all the time. The range hood can remove fumes, smoke, and bad odors. Here’s all you need to know about how to vent a range hood on an interior wall.

An inside wall is the most usual location for a range hood. An internal wall can be used to vent a range hood, whether it’s a wall model or an under kitchen cabinet model.

If you’ve never done this before, you may be apprehensive. You can, however, save money by completing the installation yourself if you’re comfortable with it. The hood should be installed by a local contractor if it isn’t already. The most difficult aspect is putting in the ducting.

Why Would You Need A Venting Range Hood?

In addition to making your kitchen appear great, a well-installed range hood can make it more functional, elegant, and safe. Cleaning time can be cut in half because of the product’s ability to swiftly absorb bad kitchen scents and trap grease.

It is essential to remove the harmful contaminants and cooking odors. Over 200 hazardous gases are found in the cooking vapors, two of which are known to be carcinogens. Consider the image of them hovering over your kitchen and living area, in which you and your family are inhaling their toxins as they pass through. Carbon dioxide buildup in the atmosphere can have long-term effects on the human body. Venting your range hood improves the quality of air in your kitchen while you’re cooking.

If You Have A Range Hood, How Do You Know What To Look For?

Homeowners are most likely to choose to install a range hood on an interior wall. As scary as it may appear, it is feasible if you have the necessary abilities and expertise. You can always hire a professional to do the work for you. If you decide to install the range hood yourself, keep in mind that it will require ducts that run along the interior walls of your home. Maximizing its effectiveness is dependent on getting it correctly the first time.

Installing a range hood on the inside of your house is far more convenient than having to scale your roof to do it. Because an elbow must be installed after about 18 inches of venting, this technique is also known as “horizontal wall venting.”

If your range hood’s CFM is high, you’ll need a wider diameter duct to maximize the sucking power. The motor of the equipment must work harder to move the maximum amount of air possible in a minute if the ducts are too small. This results in irritating, loud noises and leaks in the joints of the duct when the duct is too narrow for the range hood.

Six Steps You Need To Do On How To Vent Range Hood On An Interior Wall

The Range Hood Must Be Dismantled

To make installation easier and prevent damage to the new range hood’s components, you’ll need to take it apart.

  • After removing the double filter, remove the hood cover.
  • After that, take off the tubing that connects the two halves.
  • It is imperative that you gently remove the four-cornered pipe extension to avoid damaging the iron and plastic pieces surrounding it.
  • Check to see whether you have everything you need before starting the project.

Find Out Where It Is

An internal wall-mounted range hood vent must be placed so that it functions optimally while not detracting from the room’s decor. For this reason, you’ll need to cut a large opening to accommodate ducts. Because you can’t put the wall back together if you produce a larger hole than necessary, precision in cutting is essential.

  • A straight line should be drawn through your wall from where the top of the kitchen cabinet meets the wall, about 1/8 of an inch lower. Ensure that the vertical line reaches the location where your range hood is to be installed.
  • Now draw a horizontal line through everything you’ve just created (about 24 to 30 inches above the cooking surface). You should keep a 30-inch space from a gas range when cooking.

Take The Quickest And Clearest Route Possible

There should be no more than two elbows in the duct run. As the range hood’s exhaust system grows larger, it will have difficulties in adequately discharging the stinky, oily air.

It would be preferable if you could discover a shorter route. Take care not to become caught on electrical lines, studs, or any other obstructions. To ensure that the filthy air is transported to the outside without difficulty, the ductwork should not exceed 30 inches in length.

The ducting may need access ports to pass through the wall. Do it in your basement or attic, the finest spot for it. You may have to cut off the wall’s access points if that is not an option. A contractor should be called in if you’re unsure of what’s inside your wall.

Make A Hole 1-2 Inches Larger Than The Ductwork

As long as the ducting is properly threaded before installing the equipment, a well-fitted range hood will last for many years.

  • Create an even, properly formed hole using a hole saw.
  • To run the duct in the joist bay, you must remove the materials within.
  • To keep the structure safe, never remove any joists.
  • Make a hole in the external wall once you’re done. Ensure that the joist bay in which the duct is routed is connected to the hole on the outside of the house where the hole is located.

Using a screw and two 5 by 10s, secure your rubric beneath the barrier and then fix it in the middle. Make sure to tighten them sequentially, then fill in the hole with new drywall. As long as there are no obstructions, a pipe can easily flow through the wall.

Connect The Exhaust Duct To The Range Hood

The technical side of things is a lot more difficult than the actual installation itself. A transition piece can be used to connect the ducting to the range hood once it has been threaded outside.

  • The circular expansion hole on the range hood’s end part can be used to route the cables. Tighten the electrical cables with the help of a clamp. Cable connectors can also be used to connect two more cables. Before hanging the hood over your kitchen unit, make sure you secure the earth line to the neutral cable.
  • When selecting a mounting box, choose a 12 by 18-inch vinyl material that is easy to cut a circular hole to meet the ductwork’s dimensions. Secure the nuts on the inner surface to their locations. The mounting box can be secured to the venting unit using flat head screws. It is recommended that the screws be at least 3 inches apart.
  • To ensure a flawless fit in the mounting box, trim the vent’s flange before attaching the ducting through the hole. Using a clear exterior caulk, fill up any cracks or crevices between the mounting box and the vent.

Attach The Wall Cap To The Exterior

A wall cover should be installed at the end of the duct line to complete the installation. Keeping the duct clean and free of debris is essential for long-term efficiency.

PVC trim is an excellent solution if your range hood isn’t perfectly flush with your wall. The hole can be made watertight and the wall cap can sit properly on the outer wall.

Run the unit through its paces.

Make sure the range hood fan fitting is working properly after you finish venting the hood on the interior wall. Check the lights to make sure you connected them correctly.

When the hood fan is running, the flips of the wall cap should open and close. Observe how your kitchen smells after running your range hood for a few minutes.

Conclusion

Maintain a healthy kitchen environment in which your family can enjoy nutritious meals and clean air. It is possible to make a significant improvement by installing a vented range hood.
