How to connect the hob: gas, electric, induction


After buy­ing house­hold appli­ances for kitchen fur­ni­ture, you have to call the mas­ter for its fur­ther instal­la­tion. In most cas­es, we are dri­ven by the fear of break­ing or dam­ag­ing an expen­sive thing. How to con­nect the hob and how dif­fi­cult it is, we will tell below.

Connecting the hob

Types of hobs

Today, hobs can be either depen­dent, that is, sup­plied with ovens and inte­grat­ed into the kitchen set togeth­er, or com­plete­ly autonomous. The sec­ond case allows you to com­bine the hob and oven with heat­ing of dif­fer­ent types. The only rec­om­men­da­tion is to use the hob and oven from the same man­u­fac­tur­er. That is, you should not take the Bosh hob to the Zanus­si oven.

Hobs can be:

The type of pan­el select­ed will deter­mine how it is installed.

General tips for installing the hob

As a rule, the hob is built into the coun­ter­top of the kitchen cab­i­net. When installing a gas stove, a min­i­mum dis­tance of 5.5 cm must be observed between the wall and the pan­el. There are no such strict rules for the cor­rect loca­tion of the elec­tric and induc­tion pan­els, but it is also nec­es­sary to cal­cu­late the place. For exam­ple, in the case when you are going to cook jam in a wide basin on the rear burn­ers or put water tanks for heat­ing.

After you have cal­cu­lat­ed the future loca­tion of the hob rel­a­tive to the coun­ter­top, you need to out­line it and care­ful­ly cut it out. Use a drill or jig­saw. Don’t for­get to seal the cut. In this case, even if liq­uid boils under the hob, your coun­ter­top is not deformed.

Do not for­get that dish­es in suf­fi­cient­ly large con­tain­ers and have a lot of weight can be cooked on the hob. There­fore, coun­ter­tops with a thick­ness of less than 4 cm are sim­ply unac­cept­able for installing a hob.

Connecting a gas hob

Recall that some work when con­nect­ing a gas hob will require the manda­to­ry pres­ence of rep­re­sen­ta­tives of the gas ser­vice, there­fore, if you doubt your abil­i­ties, but want to con­nect the hob to gas, it is bet­ter to entrust the instal­la­tion to spe­cial­ists.

Connecting a gas hob

If you still decide on an inde­pen­dent con­nec­tion, then below we will instruct you step by step on how to con­nect a gas hob.

Step 1: First you need to decide on a place. Don’t be embar­rassed by the fact that the place for the hob that is con­ve­nient for you is away from the gas line. You can always bring gas to it using a spe­cial met­al cor­ru­gat­ed hose. The only lim­i­ta­tion imposed on gas hoses in a met­al braid is the pres­ence of auto-igni­tion. In such a sit­u­a­tion, an acci­den­tal short cir­cuit can pro­voke a gas igni­tion.

After you have cut a hole for the hob, lay it around the perime­ter with a spe­cial foam tape. It usu­al­ly comes with the device. If you didn’t have it in the pack­age, you can always buy this seal in stores that sell var­i­ous gas equip­ment. A pan­el is placed on top of this foam tape. The con­tact between the tape and the hob must be com­plete.

Step 2: Treat the next step as respon­si­bly as pos­si­ble. It is nec­es­sary to con­nect the gas flex­i­ble hose at one end to the gas line or gas cylin­der, and the oth­er to the blue fuel sup­ply hole in the hob. Jets for main gas and bot­tled gas dif­fer from each oth­er by a hole. In the first case, you need a wider through hole, and in the sec­ond, a nar­row one. Usu­al­ly you will receive imme­di­ate­ly con­nect­ed jets for the main gas to the hob. If you decide to use a cylin­der, then it is worth tweak­ing the fac­to­ry set­tings a lit­tle.

For these works, spe­cial­ists from the gas office may be required. They will also be able to check the gas hob as a whole and cer­ti­fy the qual­i­ty of the hose. If you nev­er­the­less make the con­nec­tion, after com­plet­ing the work per­formed, open the gas valve and check for gas leaks with­out light­ing the burn­ers. To do this, lath­er the joints. The appear­ance of bub­bles will indi­cate a lack of tight­ness.

Nuts at joints

What is left for you to do in this case? Try tight­en­ing the nuts at the joints. Don’t squeeze too hard. Paranitic pads or fum-tape may not with­stand this. It is pos­si­ble that in this case, com­plete tight­ness will not be achieved, start the con­nec­tion again and con­nect the parts, care­ful­ly secur­ing the joints.

If, after the above steps, a gas leak is still observed, call the gas ser­vice spe­cial­ists. The oper­a­tion of such a stove can be dan­ger­ous!

Step 3: In most mod­ern mod­els, auto igni­tion is pro­vid­ed. And, there­fore, you will need to con­nect the hob to the gas sup­ply sys­tem. The best option would be to install a sep­a­rate out­let in the imme­di­ate vicin­i­ty of the device.

Connecting an electric or induction hob

How to con­nect an elec­tric hob, for exam­ple, Elec­trolux, or oth­er man­u­fac­tur­ers? Con­nect­ing an induc­tion cook­er to the mains, which is a type of elec­tric type pan­el, will be iden­ti­cal. In fact, mod­els with an elec­tric and induc­tion prin­ci­ple of oper­a­tion dif­fer only in the sur­face of the hob and in the prin­ci­ple of oper­a­tion.

In induc­tion, instead of the usu­al burn­ers, there is a plane that heats the dish­es only at the points of con­tact with the hob. Because of this, on the induc­tion one should cook only in dish­es with a per­fect­ly smooth and even bot­tom.

Let’s move on to the instal­la­tion. Below is a dia­gram of the con­nec­tion of the hob glued by the man­u­fac­tur­er on the back of the tile.

Connecting an electric hob

Step 1: First you need to decide what method will be used to con­nect the hob to the mains. Will it be a spe­cial sock­et for the elec­tric stove or will you need to run a sep­a­rate pow­er line from the meter? The sec­ond is more prefer­able. If you already have a sock­et for an elec­tric stove in your apart­ment, then, of course, it does not make sense to pull a sep­a­rate pow­er line and it is eas­i­er to put a spe­cial sock­et on the out­go­ing wire.

Don’t be dis­ap­point­ed by the elec­tri­cal wire sup­plied with the hob. If its cross sec­tion is less than 4 mm and it is not cop­per, feel free to go to the store and buy a new one for replace­ment. On the reverse side of the hob, its pow­er will be writ­ten. If you see pow­er over 7 kW, then the wire cross sec­tion must be tak­en at least 6 mm. The wire itself must be three-core: phase, neu­tral and ground.

In the event that the man­u­fac­tur­er has respon­si­bly treat­ed the sup­plied spare parts and the wire turned out to have the nec­es­sary char­ac­ter­is­tics, then in order to con­nect to the pow­er line from the shield or to the oven, you will need to pur­chase a spe­cial ter­mi­nal block.

Step 2: How to con­nect the hob to the mains? This will require strip­ping the cable of each strand­ed wiring by 1 cm for fur­ther con­nec­tion to the ter­mi­nals. For con­ve­nience, it is rec­om­mend­ed to crimp stripped wires using sleeve lugs and crimp­ing pli­ers. Pli­ers are not rec­om­mend­ed.

Connect the hob to the mains

Step 3: Now look under the cov­er of the ter­mi­nal block. As a rule, there are by no means 3 ter­mi­nals. For­eign des­ig­na­tions L1, L2, L3 denote three phas­es, respec­tive­ly, N is neu­tral, and PE is ground. Since we have only one phase in our apart­ment build­ings, the jumpers sup­plied with the hob will help you. We con­nect jumpers all three phas­es on the ter­mi­nal block. In the wire, these are black, brown and white cables, respec­tive­ly. The blue or white-blue wire is respon­si­ble for the neu­tral, and the yel­low-green wire is for ground­ing.

If nec­es­sary, sev­er­al wires in the cable are twist­ed in accor­dance with the volt­age they pro­duce. When con­nect­ing wires to the ter­mi­nals, install them on the left side and twist clock­wise. So, you will save the core from being squeezed out from under the ter­mi­nal.

The yel­low-green wire should be left a lit­tle longer than the rest. Then, with exces­sive mechan­i­cal ten­sion on the cable, the pro­tec­tive con­duc­tor will be the last to break. There­fore, he will per­form the func­tion assigned to him to the max­i­mum.

Step 4: After con­nect­ing all the wires, close the ter­mi­nal block cov­er and try what you got. If you have an out­let for an elec­tric stove, do not for­get that it is nec­es­sary to turn on the plug in it when the apart­ment is com­plete­ly de-ener­gized. Only after con­nect­ing the elec­tric hob, you should again apply cur­rent to the hous­ing in order to avoid a sharp pow­er surge.

Test­ing the per­for­mance of the hob before instal­la­tion in the coun­ter­top has a very prac­ti­cal pur­pose, since the fix­ing must be done with a sealant.

To find out how to con­nect a depen­dent hob or com­bi­na­tion hob, you need to refer to the pre­vi­ous­ly described options again. The depen­dent hob is installed tak­ing into account the pow­er of the oven. As a rule, the gas input or elec­tric wire is sup­plied to both devices one. After read­ing the detailed instruc­tions on how to prop­er­ly con­nect the hob, regard­less of its type, you may have exces­sive self-con­fi­dence in your abil­i­ties due to seem­ing sim­plic­i­ty.

After the hob, do not for­get to install a hood in the kitchen.

We would like to remind you that gas and elec­tric­i­ty, if han­dled improp­er­ly, may well cause acci­dents lead­ing to seri­ous con­se­quences. There­fore, before start­ing the con­nec­tion, once again care­ful­ly study the instruc­tions, pre­pare the tools, and only after mak­ing sure. that every­thing you need for instal­la­tion is avail­able, get start­ed.
