Step By Step Process On Kitchen Exhaust Hood Duct Installation

step by step range hood installation

A proper installation process is key to achieving an efficient and effective working kitchen aspirator hood duct. It’ll be good to strictly follow the procedure to achieve a functional ductwork system in the unit. Therefore, for the chimney to vent outside, you’ll have to install the ducts on top or the back of the kitchen covering fan. Then vent the extraction hood through the ceiling or the wall in the kitchen. These steps provide the correct kitchen exhaust hood duct installation:

Step 1. Select the suitable place where your ductwork will run

It’ll be vital to find an appropriate location where you’ll locate your ductwork and allow it to run. The area you choose should be free from any big studs, electrical wiring, or any other form of wiring.

Once you find these obstacles, it’ll be good to avoid them and seek an alternative site or location. The area you should opt for should have no obstruction on its way through the house’s exterior and should be the shortest path to the kitchen’s exterior.

Step 2. Take the measurements

Use a tape measure to measure the duct opening size on top of the kitchen range hood. While measuring, you need to understand that some of the wall’s connections will be rectangles while others are round. The dusting size for the holes is always 6 or 7 inches; however, you may need the square-to-round adaptor when measuring these connections. Take accurate measurements to minimize the occurrence of errors during the installation process.

Step 3. Attach the adaptor

After taking the measurements, attach the adaptor to the extractor fan’s top carefully. While connecting, ensure that you attach the correct dust adaptor to the fan. You can achieve this by pushing the duct adaptor down over the hood’s protruding collar. Then secure the duct adapter to the stove hood’s fan using the appropriate sheet metal screws.

After which, use a cordless drill and bit to secure the adaptor using the sheet metal screws. Drive the screw on the back of the adaptor. Around the perimeter of all the fan’s sides, place either two or three screws to ensure the proper securing of the adaptor.

Step 4. Placing the wall outlet template

Place a wall outlet template on the outside wall, then use a pen to make the outlet template’s markings. Using a rotozip saw, cut out this hole that’s on the wall. The hole should pass through the interior wall to the exterior side. In most kitchens, the designers vent the fume extractor on the wall because there was limited attic space.

Step 5. Installing the vent outlet cover

You should install the outlet cover of the vent from outside the kitchen. Using a screwdriver and drywall screws, secure the vent outlet cover from inside the kitchen. The vent outlet cover will meet with the ducting system in the wall inside the kitchen. After completing, attach the two parts and seal around the two parts using the silicone. You should close the parts appropriately to prevent reduced airflow and duct leakage from the joints.

Step 6. Place the hood unit on the wall

After joining the vent outlet cover and the ducting system, you’ll need to lift the range hood and place it on the wall. The cooker hood unit may be heavy, or you may want to get an accurate position. You’ll need to get the help of a friend or a colleague. The friend can hold up the unit for you in the correct places. Then slowly and carefully slide it over the vent outlet cover you had installed from outside the kitchen.

Step 7. Mounting the fume extractor fan

Through the vent and vent cover, attach some sheet-metal screws from the system’s fan back. Then you’ll have to mount the fan with screws while using the screwdrivers through the mounting holes on the fan. Then get to the house and reset the house power; after which, test if the light and fan are working. If the whole ventilating and air circulation system is working correctly, you can move to the outside and check the duct to ensure proper movement of air.

Step 8. Install a damper

Installing a damper is very important after you’ve completed the ductwork installation process. You’ve to install it on the outside top of the duct. The main aim of the damper is to try to keep debris and dirt away from the vent. The trash and dirt may affect the proper working of the kitchen aspirator hood system. Additionally, it plays a massive role in preventing back drafting; it doesn’t allow backflow of air into the duct to interfere with the proper air circulation.

Frequently Asked Questions

Q· Between the ducted and ductless range hood, which is the best for a residential kitchen?

In most homes, homeowners prefer the ducted range hood to the ductless one.

Q· Is it essential to seal the duct’s end with either the roof or wall cap?

Yes, it’s always important to seal the joints or the ending of the ducts with either silicone, wall, or roof cap. The sealing keeps debris and any dirt away from your line. The lid also aids in preventing back-drafting, which results from air coming from outside from getting into the duct.
