Island cooktops are a great way to have more room to cook and be able to move freely in your kitchen. The use of the island can be used for cooking space, sink space and extra counter room with a clean and elegant look. The installation of the cook-top can help improve your kitchen with the use of fast warm ups and interchange parts from grills, fryers and more. While cooktops can look different, they are mostly the same when it comes to installation.

Step1. Hood Vent or Downdraft

You will need to decide whether or not you will be using a hood vent, which removes the steam and smoke to the outdoors while you are cooking, or the downdraft, which pulls the smoke and steam downwards, being placed by a wall or in the middle of the island. Most of the time you will need at least 27 to 30 inches of deep base for a downdraft system to fit properly into your island cooktop. Hood vents have options for recirculations kits if you don't want to vent the steam and smoke to connect outdoors.

Step 2. Measuring and Preparing

When installing the cook-top you will need at least 30 inches of clearance so you will be able to have enough room to install the additional hood vent or downdraft. There should be around two inches of clearance from the front of the counter top to the cutout of where the cook top will be placed. You should have enough room to move around the island. Having 25 to 30 inches should be efficient. You should check to make sure all of the electrical wires are working and make sure they are the same amp-age and wattage as described on the manufactures labels. You may want to call an electrician if you have any questions about the wires.

Step 3. Cooktop Placement

When placing the cook-top onto the island make sure your cutout is too small, rather than too big. That way, if you make a mistake you can always cutout more to make the cooktop fit. Begin to slowly place the cooktop into place. Make sure not to caulk the cooktop onto the island yet, since you may need to adjust the cooktop later. Move and adjust all of the knobs so that they are pressed down firmly into place. The brackets that come with the cooktop should now be installed as well.

Step 4. Connecting the Wires

Make sure that all of the power to the area you are working on is first turned off. Remove the cover of the junction box and begin wiring the connection from the cooktop to the junction box by using a conduit connector. Your home might have 3 to 4 different wire cables. The colors that correspond to each other should be connected together. When all of the connections are made, you may replace the cover of the junction box and begin using your new island cook-top.
