Venting a range hood on an interior wall may seem daunting. Cut a hole 1-2 inches larger than your ductwork where you’ll run the duct from your hood. So, it’s important that you know exactly where you want to vent your range hood before continuing with the installation.

For example, a 900 cfm hood attached to ductwork that is less than eight inches will not be able to move 900 cubic feet of air in a minute.

Any more than two and your exhaust system will have too much resistance to effectively vent all your greasy air to the outside. To reduce the number of elbows you’ll need, select a path that avoids studs, electrical wires, and other obstacles in your walls.

Ideally, you want to be able to have access points along your ductwork run where you can thread it through your ceiling or wall. If you can hop in your attic or basement, these are generally the easiest places to thread ductwork.

Otherwise, you may have to choose a couple of areas to cut out access points in your ceiling or wall so you can complete the installation.

3 – Cut a hole 1-2 inches larger than your ductwork where you’ll run the duct from your hood.

One to two inches gives you space to thread the ductwork through the hole so you can attach it to the hood with ease. The final step is to go outside your house and install a wall or roof cap at the end of your duct run.

To install your blower, first, you’ll need to find a place in your duct where you have room for it. Once you’ve found a place for your inline blower, you’ll need to measure it and account for some space to put transition pieces.

I’m installing a brick veneer backsplash and a chimney style vented range hood. Also, you’ll know the exact size of the backsplash and you can mount the range hood based on its location.

If any mistakes happen along the way, it will be much easier to reinstall and relocate a backsplash than a range hood. A backdraft damper, like an inline blower, is installed inside your ductwork.

Most importantly, it prevents back-drafting, which is the backward movement of outside air back inside your home. Ideally, you want all the greasy air to make it to the outside and a backdraft damper helps with that.

Install your backdraft damper close to the termination of your duct – within a few feet. Once you’ve found a place for it, cut through your ductwork and attach the damper.

Most dampers have screw holes on the top, bottom, and sides so you can firmly attach them to your ductwork.
