Tools we need to get started

Drill, tape measure, level, pencil, goggles, gloves, screwdriver.

1. Check the measurements

Check for proper height clearance, from the top of our cooking surface to the bottom of our range hood, we want to have at least 24” to 30” inches of space, if you have a gas cooktop, make sure you have at least 30” inches room between the two. This is very important for maximum efficiency and safety. So you should not skip this step.

2. Check the domestic power supply

This step is to add adequate earthing for the installation. It is also a good idea to hire a professional to make sure if these things.

3. Check the ductwork

Find the closest exterior wall and run the ductwork behind the ceiling or soffit. Run the ductwork as close to the ceiling as possible (leaving the ductwork exposed for an industrial look or building a soffit to hide it). Run the ductwork in the attic/wall through the roof. We’ll explain how to run the ductwork through the ceiling to the nearest exterior wall below.

Make a hole slightly larger than the ducting for your vent ...
... on the ceiling to run the duct through the ceiling/soffit. A hole saw is an excellent tool to create an even, perfectly-spaced opening. Remove all of the material inside so you can run the duct in the joist bay. Note: do not remove any joist as that might compromise the integrity of the building structure. If you cannot run the ductwork in the joist bay, we recommend running the ductwork exposed or through the ductwork in the attic/wall through the roof.
Once complete, you can make another hole on the outside of the house (exterior wall). The location of the hole should connect to the joist bay where you will run the duct.

Take the wall cap and fit it into the hole on the outside of the house to prepare it for mounting. If the hood does not fit tightly against the wall, you can use PVC trim to provide an even surface for the wall cap so it sits well on the exterior wall. This will help to make the hole watertight.

4. Get started to Install the range hood

Now, we should avoid any elbows upon installation for a straight run. For this purpose, we need to have at least 12 inches or one foot of space before we start any elbows.

First, we measure and mark the position of the screw hole. Take a pencil and your level to draw a vertical line on the supporting wall all the way up to the ceiling at the center of where the range hood will go. If you can’t get all the way to the ceiling, just go as high as you can go.

Next, draw a horizontal line at least 24 inches or at most 30 inches above your cooking surface. Then take your chimney bracket and place it on the wall about 1 inch from the ceiling or the upper limit. Make sure it aligns with your vertical line.

Put the range hood into place and take our drill and screw it into place so that it is nice and fastened. Always remember safety comes first.

Take our ductwork and attach it to our adapter, now a reminder, if you do not have ductwork installed. Always hire a professional but if you do, you are all set. Now, take our ductwork and our aluminum foil tape and wrap them around, making sure it is nice and secured.

The next step is to get our range hood plugged in and turn it on. Get ready to test drive this hood to make sure everything is functioning properly. Put in the rest screws for extra safety.

Install the baffle filters. And then is the chimney cover. With our level mark, we are going to put our chimney bracket screwed into place. Secure the chimney screws on the side from the cover and slide the cover into place.
