In this guide, I will go over...

  • Step-by-step on a wall mounted ZLine vent hood installation

How To Install A ZLine Range Hood?

In this installation guide, I will be going over how to install the most common type of hood sold by ZLine—the wall mount. If you want to install a Zline under cabinet hood, check out this video guide.

The basics of installing a ZLine kitchen hood is to mark the center line, and then install the two mounting screws. After placing the hood on the screws, you will install the chimney bracket, and the transition piece. This is when you install the existing duct to the round collar of the transition piece and insert the plug into a 20-amp outlet.

After making the duct and wire connection, you will fasten the upper chimney section to the chimney bracket, and the lower chimney section to the transition piece. After installing the clear grease cup and baffle channel, you can install the two stainless steel baffle filters.

Below are my detailed steps of a z line hood installation...

1. Mount The Center Line

When installing a ZLine wall mounted range hood, the first step is for you to find the center line (vertical) of the range hood.

The center line should be perfectly spaced above your cooktop or range, so that the hood can perform effectively at capturing smoke, grease, and cooking fumes.

If you can get a carpenter square or ruler, simply mark this center vertical line where you plan on installing the range hood with a pencil.

2. Mark Two Mounting Screws

Now that you have a center line, the next step is to measure out the two mounting screws from the center line.

ZLine recommends that their range hoods be 30-inches to 36-inches above your cooktop or range.

3. Build Wood Brace If Needed

Before you screw in the two mounting screws, its important to note that these mounting screws need to go into the wood studs. The range hood cannot be supported by drywall because it is not strong enough.

If the two mounting screws are not mounted by the studs, then you will have to build a wood bracing that is connected to the wall studs. And then the mounting screws can go into the wood bracing.

It's also important for the hood installer to avoid damaging existing pipe or wiring that is within the wall.

4. Install Two Mounting Screws

After marking the two mounting screws, install these screws but leave 1/4-inch of the screw head out of the wall.

Now it's time to mount the range hood on the 1/4-inch ends of the mounting screws.

And then simply finish fastening the screws so that they are flush with the hood and the wall.

5. Install Chimney Bracket

The next step is to mount the chimney bracket along the center line above the hood. The chimney bracket will help secure the metal range hood chimney.

6. Install Transition Piece

The transition piece is what secured the round duct to the rectangular top of the range hood.

You will simply fasten the transition piece to the top of the hood with the supplied screws.

7. Make The Duct Connection

After you have installed the transition piece, it is time to connect the duct.

Simply place the end of the round duct over the transition piece circular collar, and you hold it in place with a metal duct clamp.

I also recommend putting one piece of aluminum foil tape over the clamp to make it more secure and air tight.

8. Make The Electrical Connection

Once you have connected the duct, you will need to make the electrical connection.

Most ZLine range hoods will have a three pronged plug, and you can simply plug it into a kitchen outlet. The outlet should be on a 20-amp circuit.

If you don't have a nearby outlet and want to hardwire it, you will have to cut off the plug, strip the wires, and make the electrical connection with wire nuts. According to ZLine, the best outlet would be directly behind or to the side of the hood chimney.

9. Install The Chimney

Now it's time to install the two part metal rectangular chimney. 

Slide the inner section of the chimney upwards so that the vents are visible, and fasten this vented section to the chimney bracket. And then you will fasten the lower section of the chimney to the transition piece with the provided screws.

10. Install The Baffle Filters

Prior to installing the stainless steel baffle filters, ZLine advises to install the clear grease cup behind the blower motor. Now you can install the baffle channel and the baffles.

Make sure to remove any protective film over the baffle filters which may give it a white appearance.

Why Test Range Hood Prior To Install?

I always recommend to homeowners that they should check the range hood prior to installation.

If there is a three pronged plug with the hood, then you can easily plug in the hood, and check that all of the speed settings and LED lights properly work.

It is extremely frustrating to install a range hood and then realize that it isn't working properly and needs to be returned. Also make sure that the range hood came with all of the required parts prior to installing it.

How To Vent ZLine Range Hoods?

It is important to note that if you install a new range hood, these appliances need to be directly vented to the exterior. You do not want to vent a range hood into an attic, interior wall, or anywhere except to the outside.

Readers love my new guide on whether range hoods have to be vented to the outside, and it goes over this problem in detail.

The exception to this rule is if the range hood clearly states that it can be converted to a ductless or self-circulating installation, which usually requires the addition of a charcoal filter.

Why Minimize ZLine Duct Bends?

It is also a good idea to minimize the number of bends in a duct so it will minimize friction and performance loss as recommended by Zline. 

Also, if you can opt for rigid metal ducting, this type of duct is always superior to flexible ducting with ridges. The smooth surface of metal ducting allows for more air flow and better range hood performance.

Final Thoughts

Installing a ZLine range hood is pretty straightforward if you have all of the required tools, and I recommend that you read the ZLine installation manual carefully.

I probably wouldn't even try installing a range hood without a lightweight cordless drill since it can make the install so much easier.

If you don't have to install a new duct to the outside, then the hood install can probably be done within a few hours.

Just remember my golden rule to range hood installations, always test the ZLine range hood by plugging it into an outlet prior to installing it. You don't want to go through the hassle of an installation only to find out it isn't working properly, or that you are missing parts.

  1. We renovated our kitchen last year and installed a Z Line KB-30 range hood that we have not vented to the outside. We have a rear entry door that is 14′ directly opposite the stove and range hood. In the spring, summer and fall, that door is often kept open, along with the two, side-by-side, Andersen double-hung windows over the kitchen sink.
    We have found the re-circulating aspect of the KB-30 to be adequate, but not optimal. We’re considering removing the range hood and venting it to the outside. This will require some effort by our electrician and carpenter, which will involve a considerable expense.
    Do you think it is worth doing, under the circumstances I have described.

    • It’s hard to say honestly, it’s relative to your budget and perhaps how sensitive people are in your household. If cost wasn’t a concern, then venting to outside is definitely the way to go. The fumes/smoke are rising, so it will only indirectly get vented out the windows/doors after being pulled horizontally so occupants will still be breathing some of it in — which isn’t ideal.
