Installing a range hood vent through the ceiling can be a difficult task, but with the right instructions, it can be done quickly and easily. In this blog post, we will show you how to install a range hood vent through ceiling and provide some tips to make the process as easy as possible. So let’s get started!

How to Install a Range Hood Vent Through Ceiling

Nowadays, installing a range hood vent through ceiling is very common due to the aesthetic changes in kitchens. The appliances are becoming more sophisticated and modern, but they are also being built smaller to fit current aesthetics. This has prompted the need for higher placed vents above the stovetop.

Range Hood Installation – How to install a range hood vent?

There are a few different ways to install a range hood vent. The first step is deciding where you want it installed. You can have the vent come out from the wall, ceiling or both! The important thing is that the exhaust system vents outside of your home. By law, all gas-burning appliances must have an adequate venting system otherwise carbon monoxide will build up causing a hazard.

Range Hood Venting Options:

1) Wall to Outside – With this option, the exhaust system vents from your kitchen wall and outside. This can be accomplished by installing a flexible metal duct from the range hood to the wall or by installing a rectangular sheet metal duct out of the wall. Then the duct will need to be connected to a junction box and sealed with a rubber boot. From here you can install a wall thimble and connect the metal flex line from your range hood. To ensure that there is proper ventilation, it is recommended to have at least 1 square inch of vent for every 10 cubic feet of kitchen space.

2) Wall to Ceiling – With this option, the exhaust system vents from your kitchen wall and into the ceiling. This can be done by installing a rectangular sheet metal duct between the wall and ceiling. Then the duct will need to be connected to a junction box and sealed with a rubber boot. From here you can install a wall thimble and connect the metal flex line from your range hood. To ensure that there is proper ventilation, it is recommended to have at least 1 square inch of vent for every 10 cubic feet of kitchen space.

3) Wall to Ceiling to Outside – This option vents from the wall, into the ceiling and outside. This can be accomplished by installing the sheet metal ducts in the same manner as mentioned above for venting to the ceiling, but instead of connecting it to a junction box, you will need to install an adapter (a 90 degree elbow) and connect it to a wall thimble. From here you can go up through the roof with a roof thimble and down to a dryer vent or an outside wall.

How to install a range hood through ceiling?

Now that you have decided on where you want your range hood exhaust system, let’s learn how to install a range hood through the ceiling! There are two different methods to accomplish this task: through the drywall ceiling or through the steel roofing. It is recommended to use at least 5/8″ drywall for ceilings.

1) The first step is locating your stove and confirming that there are no beams, pipes or other obstructions in your way. Some houses have pre-existing duct work running through where you want to install the range hood. If this is the case, you can install around them by cutting out a section of drywall and replacing it with your sheet metal but this is not recommended because it leaves the possibility to cut into the wrong thing.

2) Once you are sure that there are no beams or other obstacles in your way, you will need to cut a hole in the ceiling. The best way to do this is by using a reciprocating saw or a drywall saw with a metal cutting blade installed.

3) After you have cut out the shape of your sheet metal duct, you will need to test fit it into place. Check the side of your range hood for measurements and cut notches into the duct so that it fits tightly against the side of your range hood.

4) Once you have fit the sheet metal to snugly fit up against your range hood, use a screwdriver to push up on all sides of the drywall closest to where your new duct will be. This will break some of the sealant holding drywall to the ceiling and make it easier for you to remove.

5) Next, you will need to use a reciprocating saw with a metal cutting blade installed or a drywall saw. Cut out all of the drywall from inside of your duct from floor to ceiling leaving about 1/4″ around the sides and top and bottom.

6) Now that you have all of the drywall cut out, test fit your new drain line. This step is very important because you want to ensure that it fits into place and does not rub or stick up against anything else around it. If it does not fit correctly, take out the range hood Duct and make more cuts as necessary with a reciprocating saw or drywall saw.

7) Once you have the Duct fitting into place, use a screwdriver to push up on all sides of the sheet metal from floor to ceiling and break some of the sealant holding it in place allowing for easier removal.

8) Using a drill with a metal drill bit installed, drill a hole through the sheet metal from top to bottom. This will be used for when you go up through the roof and down the outside, so it is best to determine what size drill bit to use by measuring your screws or bolts before drilling holes in your duct work.

9) Before going up into the roof, take a close look at the sheet metal and make sure that it fits tightly against the range hood and that there are no gaps or spaces between it and the surrounding area.

10) Trace out where you want to install your roof thimble, using a screwdriver to push up on all of the seams around your new duct work from floor to ceiling breaking some of the sealants holding it in place.

11) Using 4″ roofing nails, make sure to pound them in where you drew your line for the roof thimble. This will help to hold it in place while you secure it with screws from inside of the ceiling.

12) Now that your roof thimble is in place, go up into the roof and secure it with screws.

13) Secure your new duct work to the roof thimble with sheet metal screws, making sure that they are long enough to go through the drywall on the inside of the ceiling and reach at least 3/4″ into the roof. The more screws you use, the better because this will help to hold it in place.

14) Down inside your ceiling, use a sheet metal screw to secure the bottom of your new duct work to the top of the drywall behind where you cut out. You may have to drill a pilot hole or use a larger sheet metal screw if the two pieces are too far apart from each other for this step.

15) Once you have installed the sheet metal screw to hold the bottom of your duct, put a rope or string underneath and secure it with screws on both sides.

16) To complete this step, go back up into the roof and screw through both pieces of drywall which will be holding them together. Use as many screws as possible because this will ensure a nice, tight fit.

17) Now that your duct is installed and secure, you can use it as access to run wiring or install insulation if necessary. Using a reciprocating saw with a metal blade and metal clutch installed and wearing safety goggles, cut the drywall just above the ceiling line where you cut the sheet metal.

18) This next step is very important because you are going to be putting sheet metal screws into the ceiling joists. Before putting any in, make sure that there are no wires or pipes behind where you will be screwing since some of them could be live and dangerous if they get punctured by a drywall screw.

19) Put a screw into each side of your new duct work to hold it in place since there is no sheet metal behind this area anymore.

20) Now that you have all of the screws in place, go around and drill a hole through the top center of the drywall where you cut out to match the size of your roof thimble. After drilling a hole, make sure to clean up all of the extra drywall dust and debris since this is a fire hazard.

21) Using 4″ roofing nails, make sure to pound them in around the ceiling line where you cut your sheet metal from floor to ceiling. This will help to hold it in place while you secure it with screws from inside of the ceiling.

22) Now that your roof thimble is in place, go up into the roof and secure it with screws. Depending on how much room you have to work with, you may need to remove some material like drywall or insulation first since this can make it difficult for some people.

23) From inside of the ceiling, secure the top of your new duct with sheet metal screws and put a rope or string underneath and secure it to both sides at the bottom.

24) Now that you have completed this step, go back up into the roof and screw through both pieces of drywall which will be holding them together. Use as many screws as possible because this will ensure a nice, tight fit.

25) Go around to all of the seams where you used aluminum tape or sheet metal screws and seal them with butyl rubber sealing tape. This is what holds it in place while ensuring that there are no leaks when using your new range hood vent through the ceiling.

26) To complete this step, go back down into your ceiling and secure your new ductwork to the top of the drywall using a sheet metal screw. You may have to drill a pilot hole or use a larger sheet metal screw if the two pieces are too far apart from each other for this step.

27) At this point, you should be ready to attach your range hood vent through ceiling to your roof thimble. Use a screwdriver and a ratchet with a Phillips head bit to tighten the screws into place.

28) For this step, go back up into your roof and install metal fasteners that come with your range hood vent through ceiling kit. These will help secure everything together tightly so it does not move or rattle.

29) Now that you have completed this step, go back down into your ceiling and secure the trim cover on top of where your drywall used to be. Use a drill with a screwdriver bit and screws of your choice to attach it to the wall frame backing.

30) Finally, install any type of covering over the exposed ceiling if desired. For example, you can use sheetrock mud and tape or just paint the exposed area to match the rest of your ceiling. Or, for a more finished look, you can put up drywall over it just like what was there originally.

31) You should now be finished with installing your new range hood vent through ceiling. To test it out, stand back and plug in your range hood to make sure that everything is working properly.

32) If you feel this was too difficult for you to complete on your own, contact a professional oven installer since they will charge much less to install one for you.
