Method To Vent A Range Hood on an Interior Wall

Step 1: Remove the hood from the range.

1. Take your range hood apart to make it simpler to install.

2. The use of a double filter is unnecessary. Remove the pipe next.

3. Ensure that the four-cornered pipe extension is not twisted or deformed by gently removing it.

4. You must plan and ensure that all of the details are in order.

Step 2: Determine the location.

The location of the range hood’s exhaust vent on the internal wall is critical. You want to make it as efficient as possible without sacrificing the room’s aesthetic appeal.

1. You will have to cut a large hole in your wall to accommodate the ducting. Unfortunately, the gap is difficult to repair if it’s too huge, so take your time while cutting.

2. Make a mark approximately 1/8th of an inch below the top of the kitchen wall. Make a straight line down the wall after that. End your range hood at the bottom of this vertical line.

3. Start at the cooking surface and draw a horizontal line to the right. Keep a distance of at least 30 inches between the bottom of the hood and the gas stove.

Step 3: Choose the route that is clear and unimpeded.

1. The duct should not have more than two elbows. Exhaust systems that are too massive will not be able to dissipate the exhaust fumes adequately.

2. It’s time to look for a more efficient approach. But, first, ensure that the ductwork is at least 30 inches long to prevent the contaminated air from traveling too far.

3. The ducting needs access points to be weaved through the wall. The basement or attic is the most excellent place for this. Consult a home contractor before you begin cutting into your wall.

4. Make a hole 2-3 inches bigger than the ductwork.

5. A well-fitted range hood can last for many years. The ducting may be easily threaded through a 1- to 2-inch-wide opening while the equipment is attached.

Step 4: Cut a straight, round hole with a hole saw.

1. Run the duct through the joist bay by removing everything from the inside. Never release a joist from the building to preserve its structural integrity.

2. Once the hole has been drilled, position it on the outside of the building. The hole should be located on the outer wall and linked to the joist bay to install the duct.

3. Attach two 5 by 10s to the middle of your rubric with a screw. Screw the top and bottom of the barrier in place. Then use new drywall to fill up the hole. The pipe and other materials may easily flow through the wall from the inside to the outside.

Step 5: Connect the range hood to the ducting.

Even if the process of installing is straightforward, the technical parts are more challenging. However, a transition piece is all that is needed to connect the range hood to the ductwork.

1. Use an oval hole in the range hood’s crown to feed the wires. A clamp is used for tightening electrical lines. You can plug two cables into one another with the help of cable connectors. Attach the earth line and the neutral cable before you hang the range hood on your kitchen cabinet.

2. A vinyl sheet of 12 by 18 inches is ideal for attaching boxes. Circular holes may be easily made in the ducting using this tool. Glue the nuts to the insides of the cylinders. The venting device is attached to the mounting box using flat head screws. There should be at least 3 inches of room between the screws.

3. Before installing the ducting, trim the vent’s edge to ensure a flawless fit. To cover the gap between the duct and its mounting box, use an external sealant.

Step 6: Apply the wall cap to your outer wall as instructed.

1. Each duct’s end cap may be finished off with a wall cover to complete the installation. Keeping dirt and debris out of the vent is the purpose of this. It guarantees long-term performance.

2. Make your range hood fit tightly against the wall by using PVC trim. Allows the wall cap to be placed on the outer wall in a precise position.

Step 7: Check the unit before using it.

1. Switch the power supply on and ensure the range hood fan is running once you vent it. Make sure the connections are working correctly as well.

2. When the fan is functioning, the wall cap should extend. While you wait for the scent to go, you may run your range hood to see if it helps.

Essential Tips For Venting A Range Hood

1. Here are some tips to help installation go as smoothly as possible.

2. If you know what you’re looking for, you’ll be able to find the ideal hoods for your needs. Knowing how many cubic feet per minute (CFM) you’ll require is essential. Please take a look at the space in your kitchen and see whether it’s big enough for what you need. To get the optimal CFM for your kitchen, increase the square footage by 2.

3. Consider the area above the stove. The range hood should be 20-24 inches away from the oven. The distance required is larger for gas stoves.

4. Disconnect any electrical connections before attempting to install the device. Switch off the kitchen’s power supply to prevent electrical dangers.

5. Use caution while handling any electrical device.

6. The voltage of the socket into which the range hood vent is plugged must be correct. Power supplies for outlets and cables may be checked by looking at their labels.

7. You cannot void the warranty on the items you have bought. However, a defective product may be eligible for a return or refund.

8. Remove all of the cables from the device.

9. Ensure you don’t exceed 40 feet of ducting to get effective ventilation.

10. Condensation and leaks may be avoided by duct insulation.


Is the range hood effective at sucking in unwanted air?

With the help of a vented hood fan, odors might be trapped against the filter. With its powerful suctioning ability, this kitchen appliance can efficiently remove unwanted odors or pollutants from the kitchen.

There are a lot more gases and odors produced when you cook using your stove and oven. In particular, this is true for gas stoves. Lots of harmful pollutants are present in cooking fumes, making them potentially hazardous, and some are even known to cause cancer.

To get the most out of your range hood, you’ll need to install the vent system where the exhaust will travel out of the kitchen.

Is it possible to convert and exhaust a recirculating range hood?

If you’re looking to convert a recirculating range hood (ductless) into a ducted range hood, you can do this if the range hood is convertible. That means you can remove the recirculating kit, and let the air exhaust into the duct system. Retrofitting an existing range hood allows for the creation of ventilated range hoods.


This guide on how to vent a range hood on an interior wall aids with installing a range hood in your kitchen. It will not only keeps away cooking fumes, but also makes your kitchen space more hygienic with less grease. Most of the time, a range hood is installed in the interior wall rather than the ceiling.
