Induction has revolutionized the way of cooking with electricity. The renovation of the kitchen is an opportunity to install this type of device that integrates without difficulty into the thickness of a work plan.

How to install a built-in hob

Induction cooktops use an electromagnetic field (generated by inductors) that transmits heat directly to the metal of the cookware placed on the ceramic hob. By this method, the surface remains substantially cold.

An undeniable advantage

If it avoids the risk of burns, this method of cooking mainly prevents the dispersion of heat (source of waste) and the prolongation of cooking that results from the thermal inertia proper to the electric plates (which, they heat, by conduction). The heating of the kitchen utensils stops immediately when the induction is cut off, an important advantage in case of programming in the absence of supervision.

Precautions to take with induction

The induction hob requires the use of special kitchen tools with a ferro-metallic structure and a thicker bottom to prevent them from being deformed due to the rapidity of the thermal variations. To avoid therefore: utensils made of glass, ceramic, earth or copper. A test carried out with a magnet makes it possible to check if the bottom of the container contains iron (if it is the case, one can thus use it). Attention also to the impact of electromagnetic fields on nearby electronic devices or magnetic cards!

Steps for laying an induction plate

Measuring and cutting a kitchen worktop

The rim being 1 cm wide, make the cutting from the top of the worktop, without fear of splinters.
It is only necessary to respect around a safety zone of 4 cm.

Draw the measurements to cut out a work plan

According to the dimensions provided, trace the cutout on the worktop.
Take care to center this layout according to the configuration of other kitchen equipment.

Drill a work plan

Drill (Ø 10 mm wood drill bit) inside the corners of the path.
The holes facilitate the introduction of the blade of the jigsaw at the start of each line to be cut.

Cut a work plan

Make the cuts inside the lines.
The thickness of the cutting plane being important (here 40 mm), keep the saw flat to obtain a perfectly vertical cut.

Embed a cooktop in a worktop

Turn the cooktop over and place the supplied sealing gasket around the edge of the cooktop.
At the corners, fix it edge to edge to avoid any extra thickness.

Lay an induction plate on a work surface

Put the appliance in position by disengaging the power supply cable which will be connected to the protected circuit provided for this table or connected by a suitable plug and socket.

Connect a baking tray

Remove the three power supply wires from the housing: neutral (blue), phase (black or red) and earth (yellow and green).
Check their diameter (6 mm2 for 32 A) and connect them with a domino.

Connecting a hob

Route the power cable of the appliance into the inner clamping collar (inside the lid) to prevent any risk of tearing. Replace the cover and screw it on.

• Preferably opt for a table with two circular fireplaces (small and medium) and a multizone with a circular fireplace (large) expandable to a long area for casserole or baking dish.
• Since the induction hob does not give off heat and is furthermore ventilated, it is possible to insert another household appliance underneath or even to have a cutlery drawer there, being careful not to disturb the air intakes located under the appliance. the carcass of the device.
• To avoid damaging the table, avoid depositing an aluminum sheet or tray.

Can we replace a gas hob with an induction?

Christian Pessey's answer:
Nothing stands in the way of making this transformation yourself if the dimensions of the two plates are identical. The electrical safety rules must be carefully followed to make the connection.

  • The standard NF C 15-100 must be respected.
  • The power supply circuit must be protected by a differential device (30 mA) and by a division circuit breaker adapted to the power of your equipment (40 A usually).
  • The conductor section for this type of device is 6 mm², and the plate must be grounded.
