How To Install A Range Hood [Step By Step Guide]

Before you can start installing a new range hood in your home, you will need to follow some procedures first. 

When you purchase the new range hood, you will generally find the owner’s manual in which you will find all the instructions that you need to follow in installing the new range hood. 

However, before you go out there to purchase the new range hood, you need to make sure that you pick the right one for your home. 

To make sure of that, here are some things you should do before purchasing the new range hood. 

Things You Should Consider Before Buying A New Range Hood

So before you get the new range hood, you have to make sure you get the right one. Follow these below to make exactly sure of that.

  • You will have to measure the width of your range before purchasing the new one. The new hood would be roughly the same width as your range.
  • The square footage of your kitchen will also have to be considered when you are going to get a new range hood. The vent hoods usually are measured according to the amount of air they can clear per minute, per square footage (CFM). The results will also vary based on the type of kitchen you have and the layout of your home. Having a closed-off or open concept kitchen will also be considered for the results you get. The new hood should be around double your kitchen’s square footage. So, if you have a kitchen that is about 150sq ft, you should be looking to get a range hood with a 300 sq ft CFM. Also, be sure to check out the manufacturer’s recommendations for minimum CFM for your appliances and choose the number with the highest recommendations. Be sure to comply with all the local and state standards as well.
  • Checking the BTU is also something you will have to do. When your new range hood is going to be installed over gas cookers, the BTU threshold of the new hood will have to meet or pass the total BTU output of the cooking surface. This will enable the new range hood to handle the amount of heat that the cooktop or the range will produce.
  • Your cooking style should also be considered when choosing a new hood for your kitchen. If you are someone who fries and steams a lot, increasing the CFM will ensure that you get enough ventilation in your kitchen.

So these are some of the things that need to be considered before you decide to buy a new range hood. Let us get going.

How To Install A New Range Hood

So after you have gotten the materials and the tools you will need for the job, you can now commence installing the new range hood. Follow the steps here closely to get the job done. 

Steps For Installing Your New Range Hood

  • Step 1 – Removing The Old Rangehood

Before installing the new range hood, you will have to get rid of the old one first if there is an old range hood already there. 

First, get to the breaker box and switch the power to the range hood. It would help if you did this before installing the new range hood. 

Unplug the old range hood and make sure to disconnect all its electrical wires. You may need to get another person to help you with the uninstallation process during this process. 

The person will help by holding up the old range hood while removing the support screws.

  • Step 2 – Locating And Marking Vent Hood

You now measure the new range hood to see where its vent will be coming out. 

If the vent came along with a paper template, you should then use that template to measure the space on the wall where the vent hole will be. 

You can also use measurements from your hood to pinpoint where the new vent hole will be on your wall if the hood does not come with its paper template. 

  • Step 3 – Checking The Vent Wall 

It would help by first cutting a small portion of the wall where the vent hole will be before you bore a giant hole in it. 

You then make sure that there are no plumbing or any forms of electrical wires behind that wall since if there are any, it could interfere with the installation work you are about to do. 

If you come across plumbing or electrical wiring behind the wall, the best thing to do will be to consult a professional before going ahead with the next steps in this article. 

This is because, in such situations, you may have to vent through the roof instead of through the wall. Venting through the roof can also be quite a complicated process on its own.

  • Step 4- Cut The Interior Hole Of The Vent

After making sure that you are clear to cut through the wall that will lead to the vent outside the kitchen, you then cut a hole through the wall up to about six inches wide with an oscillating tool or a reciprocating saw. 

The hole can be made a little bigger to allow you more room to work with if you prefer it that way. 

You then use your long drill bit to place the locator holes extending to the outside of the wall. 

You should place the locator hole on the edges of the vent hole.

  • Step 5 – Now Cut The Vent Pipe Hole

Before you start cutting the vent pipe hole on the outside wall, the locator holes should be connected to form a circle through which you will be missing. 

You will have to use either a reciprocating saw or an oscillating tool. If the exterior of the wall is paneled or uneven, it would be easier to cut a square piece of PVC trim and place it on the exterior wall before you cut the hole through the trim.

  • Step 6 – Attaching The Duct Or Range Hood Vent Cap

Now, push the vent cap into the exterior opening or the PVC trim. You have to make sure that it is long enough to connect to the range hood. Now, attach the screws and the caulk to get a tight waterproof seal. 

  • Step 7 – Prepping The Damper

After you set the waterproof caulk, you will now look for the damper that came with the new range hood. 

Measure the damper against the interior hole so that you will be able to know the amount of space you will need for the duct size. 

With a small amount of duct, test to see if you have the correct measurements before you go ahead and cut a more significant piece of duct. 

Now, mark the outside of the damper to use it as a reference for where you will be taping the ductwork.

  • Step 8 – Running The Electrical Wiring

You may have to drill holes next to each side of the vent to enable you to run the electrical wiring from the range hood over to the electrical box. 

Make sure that you have enough conduit and wires from the breaker box to the electrical terminal box of the range hood. 

Check that your electrical wiring is up to code. You can get an electrician to handle the electrical wiring part for you if you are not confident, and I recommend you do so.

  • Step 9 – Positioning The Range Hood

With this, you will need to get a second person to help you by holding the weight of the range hood while you place all the mounting slots on the hood.

You then remove the grease filter to get you better access to tighten and secure the screws. Now level the hood and tighten the upper screws as well.

  • Step 10 – Connecting The Wiring

Here, you clip off any excess wiring and then strip back the wires to connect them with the caps and or the connectors. 

You should match the colors of the wiring to the corresponding color of the connector and then check the upper copper ground wire to the grounding wire connector.

  • Step 11 – Installing The Vent Covers

After you connect the wires, you can now turn the power on again to see if the range hood is working perfectly. 

Once you have ensured that, you can then proceed to install the vent covers with the help of the range hood owner’s manual. 

Please make sure to follow the instructions in the owner’s manual precisely to the letter.

So this is how you install your new range hood in your kitchen. It may seem like a complex process to follow, but it is pretty straightforward. 

You can also pay extra to get professionals to install it if you think it is too much of a task for you.
