How to Install a Downdraft Cooktop

Using a downdraft cooktop means that you don't need to install a separate cooker hood because the smoke, odors and steam are all pulled down. This prevents the fumes from entering the air of the kitchen. Downdraft cooktops are popular for use against a wall or on a kitchen island where cooktop hoods may not be suitable. Installing a downdraft cooktop is something that you can do yourself with the necessary tools and equipment.

Step 1 - Measuring

You will first need to measure up the size of space you have for a cooktop. Make sure that you choose an area where the airflow isn't restricted by electrical sockets or gas outlets. This could prevent the downdraft from working properly.

Once you have found the space for your cooktop, you then need to spend time finding the right one. There are a number of different sizes available which may be suitable for your kitchen.

Step 2 - Siting the Downdraft Cooktop

Position the new piece on the cooktop and experiment with its exact placement. It should be arranged so that it is half an inch away from the wall. Make sure you are happy with the position before continuing to the next step.

Step 3 - Fixing the Cooktop

Most cooktops have 4 brackets that screw into from under the counter. This will ensure that the fixings are hidden and don't need filling. There are also brackets on the downdraft that will be mounted against the wall. These should also be fixed using screws. Using pieces of plywood it is also possible to level the downdrafts so that they work the best they possibly can.

Step 4 - Fitting the Control Module

There will also be a separate control module that you will need to fit close to the downdraft against the wall. It normally involves drilling a few holes and then using nuts and bolts to clamp the control module to the countertop. This will be how you control the downdraft which will help to remove smells and smoke from your kitchen.

Step 5 - Caulking

If there are any gaps between the cooktop and the countertop, use your caulking gun to fill the gap. This is an easy job as long as you take your time. Use a wet finger to smooth the caulking out and create a much better finish.

Step 6 - Finishing Touches and Testing

Connect your downdraft cooktop up to the electrical supply. Depending on the model you choose, it will either be plugged into an electrical outlet or wired directly into the electricity supply.

Experiment with the different settings of the downdraft vents to remove as much of the odors and fumes possible.
