3 Ways to Install a Cooktop Stove

The idea of ​​installing a cooktop stove can be intimidating. After all, you're dealing with gas or electricity while handling an expensive appliance. The good news is that none of the individual steps of this installation are too difficult. Just drive them carefully and in the correct order from start to finish.


Method 1 of 3: Installing an Electric Cooktop Stove

Install a Cooktop Step 1

Step 1. Remove the old cooktop, if there is one

If you are replacing, this step is necessary. turn off the power of the room in the fuse box. Remove caulking and stuck parts. Disconnect the wiring, memorizing how it's done, and lift the stove off the counter.

  • You must be absolutely sure that the power is off. It is possible to use a circuit tester to verify this; simply touch any wire on the cooktop that is not green or white with one tip of the tool and touch another wire (ground) that is green or white. If the light turns on, it means the power is still on.
  • Memorize how the old wires were connected, as the new wiring must be installed in the same way. You can even tag the wires and take a photo of them before removing them.
  • Get someone to help you lift the cooktop off its base - it can be quite heavy.

Step 2. There must be enough space in the new location

Ideally, there should be at least 75 cm of clearance above the cooktop and between 30 and 60 cm on the sides. Also check if the bench has enough space for the appliance model.

Check the manufacturer's instructions for your cooktop's specific requirements

Step 3. Find out if there is a suitable junction box in place

Most cooktops require a 240 VAC enclosure. If you are replacing your old device, you probably already have this part installed.

  • If you don't have a junction box, have a professional install one for you.
  • You should also find out if the old cooktop has the same amperage as the new one - if not, the new wiring must be installed by a professional. Many older stoves have circuits of only 30 amps, while modern ones usually have 40 or 50 amps.

Step 4. Measure the dimensions of the cooktop and make sure it fits in the hole where it will be installed

If you have removed a previously installed appliance, it probably already has a hole. So check the measurements of the new cooktop to see if it fits.

Measure the length and width of the cooktop and subtract 2.5 cm from each side to account for the portion that will overlap the countertop

Install a Cooktop Step 5

Step 5. Change the hole in the countertop so the cooktop fits

It should be the size of the stove - minus 2.5 cm for the overlapped part. If there is no hole or if it is too small, you will have to adapt it to make it bigger. If it's too big, you can screw shims (long, flat metal pieces) into the sides of the opening.

  • It may be necessary to remove tiles around the area before making cuts in the countertop with a saw.
  • You will need an electric cutter to work with a granite countertop. Another option is to hire a professional for this task, as it can be difficult to cut this material. A sealant must be applied to the stone before installing the cooktop.

Step 6. Release the removable parts from the cooktop to facilitate its installation

It may have mouths, screens or other parts that can be removed and stored for now. You should also remove packaging residue (such as Styrofoam) that is still on the device.

Install a Cooktop Step 7

Step 7. Install springs and support parts

They will keep the cooktop in place. You must do this installation at the top of the hole and finish it with screws.

If you have a granite countertop, secure the support pieces using double-sided tape instead of screws

Install a Cooktop Step 8

Step 8. Take the new cooktop to its place

Place it over the hole opening. Pull the threads through it beforehand. Press the device down until you hear the springs and support parts click.

If you have removed tiles, you will need to re-install them evenly against the edges of the cooktop before finalizing the process. You may have to wait 24 hours for these tiles to set before bringing the cooktop to the counter

Install a Cooktop Step 9

Step 9. Connect new cooktop wires to power

she must still be turned off when you do, in order to avoid injury and shock. Connect the stove wires to the corresponding ones on the power.

  • Red and black (or other colored) wires carry electricity to the device. Connect the cooktop wires to these colored cables in the power box.
  • The white wire is neutral and completes the circuit. The wire that stays in the power box will be connected to its corresponding one in the cooktop.
  • The green wire is what ground the circuit. Connect the green wire coming out of the cooktop to the same color wire in the power box.
  • Connect all cables using twist connectors - pieces similar to plastic caps. Align the strands together and twist them together. Snap connectors into joints. Connectors prevent exposed copper parts from touching - which prevents fire.

Step 10. Install the removable cooktop parts

Put back the mouths, screens and other pieces.

Install a Cooktop Step 11

Step 11. Turn power back on and test the cooktop

Turn on the stove to see if everything is working fine.

Method 2 of 3: Installing a Gas Cooktop Stove

Install a Cooktop Step 12

Step 1. First of all, check that the gas passes through the installation site

A gas cooktop will need a pipe to deliver fuel to the flames. If you are changing a cooktop of this type, then you already have the piping installed.

If you don't have the piping, hire a professional to install it. It is especially important that it is done correctly, as leaks can cause fires; moreover, the gas can be harmful if inhaled

Install a Cooktop Step 13

Step 2. Remove the closet doors and everything inside them

This can help you access the space under the cooktop more easily. Remove anything stored in the cabinet to make the gas tubing and hose easier to handle.

To remove the doors, you can unscrew the hinges

Install a Cooktop Step 14

Step 3. Turn off the old cooktop's gas supply

There will be a small valve used to connect the flexible hose from the stove to the house's internal piping. Rotate it until it is perpendicular to the hose or sticks out to the side.

  • If you don't close it completely, the piping will continue to release gas when you disconnect the hose, which could cause fire or suffocation.
  • When the pipeline is open, the valve handle points in the direction of gas flow. It is very important that you turn it 90 degrees to close the valve.
Install a Cooktop Step 15

Step 4. Unplug the power cord

Many gas cooktops have these cables, which provide electricity to the burners. You must unplug it from the wall outlet before proceeding.

Install a Cooktop Step 16

Step 5. Turn all mouths on for a while

Even though you have turned off the gas valve, there may still be material residue in the hose. Opening the valves allows this substance to escape. Do not light the fire. This process will take a few minutes.

Open the cooktop mouths with the hood on so that the gas is dispersed

Install a Cooktop Step 17

Step 6. Disconnect the flexible gas tubing from the wall using two wrenches

Use one of them to press the hose end nut; with the other, press the pipe nut.

  • Firmly hold the wrench that holds the pipe nut.
  • Turn the wrench attached to the flexible hose counterclockwise to unscrew the part. Continue turning until the hose is completely disconnected from the wall tube.
  • Some tubes have special parts that fit between the tubing and flexible hose. Keep this part in place when releasing the hose.

Step 7. Remove the removable parts from the cooktop

Remove mouths, grates and other items before proceeding. This will make it easier to move around the stove.

Install a Cooktop Step 19

Step 8. Remove screws and brackets from the installed cooktop in order to loosen it

Install a Cooktop Step 20

Step 9. Push the cooktop up to lift it off the countertop

Remove it from the workbench and put it in a safe place. Don't forget that the hose will still be attached when you pull it.

To avoid damage, leave it upside down

Install a Cooktop Step 21

Step 10. Remove the hose from the cooktop

If you are going to reuse the hose on your new stove, unscrew it from the old one. Use two wrenches to remove the part, securing one to the cooktop and one to the hose nut.

Turn the wrench connected to the hose counterclockwise to unscrew it

Install a Cooktop Step 22

Step 11. Attach the hose to the new cooktop

Apply a pipe sealant to the parts where this hose connects to the stove. Spread the product on the surface of the parts - but be careful not to let it "enter" the hose. Use the spanner to screw the hose to the stove.

  • The parts on the cooktop must be completely covered by the sealant - this will prevent gas leaks in the future.
  • Some cooktops have a regulator piece that keeps the gas pressure constant. If the appliance has this part, attach it to the parts of the stove and the hose. Apply sealant to products before screwing on the regulator and hose.
  • Use a small brush to apply the sealant if the product container does not include one.
Install a Cooktop Step 23

Step 12. Place the new cooktop in its place on the countertop

Slide it in carefully so as not to damage the valves. You must also pass the hose through the opening in the countertop before installing the stove.

Install a Cooktop Step 24

Step 13. Attach the hose to the wall piping

Apply sealant to the pieces on the wall. Then screw on the flexible hose using a spanner. Tighten everything very well.

Spread sealant over all parts to prevent leakage

Install a Cooktop Step 25

Step 14. Make a 1:1 mixture of soap and water

Use it to test for leaks. Stir the solution well and apply it to all connections – if you like, use a brush. Connect the wall tube valve; to do this, rotate it until it is in the same direction as the gas flow.

  • Check connections for bubbles. Also, try to make sure you don't smell gas. These could be signs of leaks.
  • If there is a leak, turn off the valve immediately. Unscrew connections, apply more sealant and reconnect. Test them again using the soap and water mixture.
  • Check it several times to make sure there are no leaks. You must also carefully inspect all connections made.
Install a Cooktop Step 26

Step 15. Turn on the stove burners to see if it works properly

If there are no leaks after testing with the mixture, try connecting the mouths. It may take a few seconds for the gas to pass through the inside of the cooktop and the fire ignites.

  • You can smell gas before it lights up; before that, make sure the hose is working before that.
  • If nothing happens after four seconds, turn off the stove flame and wait a few minutes before trying again.
Install a Cooktop Step 27

Step 16. Screw the pieces that secure the cooktop to the countertop

Now that it is working properly, install the supporting parts. Your gas cooktop is fully installed.

Reinstall the cabinets and drawers you removed earlier and return products to shelves

Method 3 of 3: Choosing a Cooktop Stove

Install a Cooktop Step 28

Step 1. Choose a cooktop when you want to separate the oven from the stove

These appliances can be useful as you can install them on separate islands or furniture in the kitchen. They are also suitable for people who want to install indoor ovens - easier to operate than normal ones.

  • Cooktops also allow two people to use two accessories at the same time.
  • They are more discreet than normal appliances as they can be installed "leveled" with benches.
  • Also, they can be easier to clean.
Install a Cooktop Step 29

Step 2. If you do not want to install a suspended hood, use a hood built into the bench

If you have to install the cooktop on an island and don't want to use an exhaust fan, you can use a countertop hood.

  • This type of ventilation brings air from the surface to the area below the stove.
  • Some cooktops are sold with retractable ducts that can be hidden in the countertop while the stove is not in use.
Install a Cooktop Step 30

Step 3. Choose between a gas and electric cooktop

Traditionally, gas cooktops were chosen because they reacted instantly when lit - and could be easily adjusted. However, modern electric cooktops also heat up quickly and are sold in low heat versions.

  • You should also consider style, size, number of burners, color, cost, materials, and safety features when purchasing a cooktop.
  • Examine the cost of operating gas and electric stoves. You can also compare gas and energy prices.
Install a Cooktop Step 31

Step 4. Decide how many mouths you need

In most cases, a four-burner unit is enough to make a meal for a family. However, if you are hosting parties or having dinners with more people, a larger number may be necessary. Decide how many mouths to use on specific occasions.

Install a Cooktop Step 32

Step 5. Choose a cooktop that fits in your kitchen

If you are replacing an old part, check if the new one can fit into the vacant space. If it's a different size, make sure the space you have can be adapted.

Install a Cooktop Step 33

Step 6. Consider the financial implications

Gas stoves may be more expensive, but they will cost less in the long run because fuel is cheaper than electricity.

You should also consider the costs of installing wiring (for electric stoves) or gas piping (for gas stoves) if there are no such installations on site


  • Ask for help when transporting the cooktop from the countertop to where it will be stored to avoid possible damage.
  • Try to buy a cooktop that is the same type as the old stove for ease of installation. For example: exchange a gas cooktop for another gas appliance. If the old part is electric, get a new one that is also electric.
  • If replacing an electric cooktop, check the amperage and see if both appliances have the same value. Many older models use 30 amps, while newer models tend to use 40 or 50. Ask a professional to change the wiring if the fixtures have different amps.


  • If you are not comfortable dealing with wiring or installing gas pipes, hire a professional to do it for you. It will follow all the necessary regulations for your new installation to be safe.
  • Apply sealant completely around the gas piping so there is no risk of leakage.
  • Be very careful; there should be no gas leaks or bare electrical wires touching each other - this can cause short circuits and lead to fires.
