Rules for connecting a gas hob to the main gas pipeline

The appearance of hobs on the market has made it possible to increase the functionality of the work area of ​​even the smallest kitchens. Therefore, these devices are very popular today. Manufacturers offer both electric and gas models, so you can choose any of them to suit your needs. There are no problems with electrical appliances, or rather, with their connection. All you need is a suitable socket. But connecting a gas hob has special requirements and strict rules that everyone should know about. Therefore, let's look into this topic.

Preparation

The preparatory stage is very important when installing the panel.
The safety of the kitchen unit and the visual appeal of the room as a whole depend on the correctness of the calculations used for the insertion. An error of even 1 cm can cause damage to the tabletop. It is recommended to focus on the dimensions prescribed by the equipment manufacturer in the instructions.

Measurements

The dimensions of most panels are the same - 55-57 cm

You need to pay attention to the size of the hole for installing equipment. To take certain measurements you will need a tape measure

The panel is turned upside down. The length and width of the equipment is then measured along the inner edge.

It is worth noting that the instructions indicate the minimum distance from the edge of the tabletop. It is not recommended to reduce it, but you can increase it. Failure to comply with this rule may result in surface breakage.

Before cutting a recess, you need to make sure that the required distances are maintained between the slab and surrounding objects. These numbers are usually written on the operating sheet.

How to connect a hob - step-by-step installation and connection instructions (80 photos)

It is difficult to imagine technological kitchens without energy-consuming appliances. The main assistants: a stove, a refrigerator and a sink are indispensable attributes of the current kitchen space. If connecting a refrigerator is simple, you only need an socket into which you plug a plug, then connecting the hob needs to be done thoughtfully.

The appearance, design and principle of operation of plates placed on countertops are varied. The gallery shows photos of hobs from different manufacturers.

Three basic types are sold: electric, gas and combined. The names explain the principle of operation, the first ones use electricity, the second ones heat the burners by burning gas, the third ones use both heat sources.

Before purchasing, you need to make a calculation of the electrical wiring based on the power consumption of the stove and oven. Apartments in old buildings cannot withstand heavy loads; they don’t even have simple grounding. In this case, an overrated automatic machine will not help; the wiring will overheat.

An electric hob of any type must be connected by a separate wiring line directly from the distribution panel.

The kitchens of the new apartments are equipped with separate wiring for stoves, automatic switches and grounding. The cross-sectional area of ​​the conductors is at least 3.5-4 mm.

Connection methods

A ready-made, thoughtful kitchen design will help you decide how to connect the hob to the power supply. Two ways:

Directly. Pull the wire from the distribution panel to the panel terminals. The cable cross-section is selected depending on the power of the stove.

The electrical wiring made must be protected, and additionally have a switch to turn off the stove in an emergency. The length should be sufficient and comfortable when connecting, and not dangle.

The wiring can be hidden and led out near the connection point. Exposed wiring is simply mounted on the wall.

Through a socket. In new apartments designed for the use of electric stoves, a power outlet is already installed in the kitchen.

The selection of the plug is made according to the rated current for the kitchen appliances being installed, so when purchasing a stove and oven, you should find out their electrical characteristics from the seller. The plug and socket inputs are connected to the terminals according to the designated diagrams.

Networks in houses are single-phase and three-phase. Based on this factor, a power socket with 3 or 4-5 connection pins is taken.

A flexible multi-core connection cable is required, with a core cross-section no smaller than that of the wiring. You should calculate the length of the cable from the outlet to the connection point; there should be no excessive tension, sagging, or twisting into rings.

The cable should not be heated by hot stoves, ovens or other hot objects. It is strictly prohibited to place the connecting wire on the floor.

How to connect the hob and oven?

An independent electric oven is connected separately, the combined panel is connected to the oven through terminals according to the attached diagram. Manufacturers of kitchen appliances make connections and terminals in their own way. But everyone has “ground, zero and phase”, only the number of phases varies.

If the apartment wiring is single-phase, the stove is connected by first connecting the ends of the phase with a jumper. Manufacturers supplement the equipment set with jumpers suitable for connection.

The installation instructions show you how to connect the hob yourself. The diagrams are shown on the back of the instrument housing. From several options for cases of different numbers of phases and pins, you should choose the appropriate one.

Example. Electrolux stove models are equipped with two phase terminals. They can be connected to two separate phases or pre-combined with a jumper and connected to one phase for single-phase wiring of the apartment.

Subtleties of connection

Use insulated wire with the required number of cores and rated cross-section.

Check the installed sockets first, builders are people too, they can make mistakes.

Follow the connection order:

• Earth-earth;
• Zero zero;
• Phases one after another, if there are many of them.

How to connect a gas hob to electricity? The useful electric ignition function does not require a non-standard connection. A simple electrical outlet will do the job.

The requirements for the connecting cable remain the same: no tension, no sagging, no heating.

Connecting a hob requires a lot of skill; if you are not confident in your abilities, call an electrician.

What to choose: mechanical or automatic electric ignition?

Like a car transmission, electric ignition is divided into two types: automatic and mechanical.

1. A stove with a mechanical electric ignition function has a button that must be pressed after the switch has been turned. Thus, the high voltage circuit is closed, a spark appears, and as a result the burner ignites.
2. If the stove has automatic electric ignition, then you don’t need to press anything. Simply turn the switch and lightly press it.

What conditions are necessary for such equipment to operate?

Of course, the main condition for the operation of a stove with electric ignition is the presence of electricity.

First you will need to connect the equipment to the electrical network.

Stove device.

For these purposes, you will need a grounded outlet and surge-resistant voltage.

If power surges occur in your home from time to time, before purchasing a stove with electric ignition, find out which models are most resistant to power surges.

In most cases, such slabs are produced by Russian manufacturers. These models best tolerate voltage fluctuations.

Will a stove with electric ignition work in the absence of electricity?

This question probably worries any person who decides to buy a stove with electric ignition. In fact, even if the lights are turned off, the stove will work. There is only one point: you will have to turn on the gas using the old, proven method, i.e. using matches or a lighter.

So you don't have to worry. If the power in your apartment or house suddenly goes out, you will not be left without a hot dinner.

Features and nuances of installation

The installation rules stipulate that any work on connecting or moving the location of gas equipment must be carried out in accordance with current standards and rules, warning gas services about replacing the heating device. When purchasing a panel, it is better to immediately clarify how it is attached to the countertop. The material of the base itself also matters; if you can handle chipboard yourself, it is better to entrust cutting into artificial stone to professionals.

You can easily install hobs yourself. The main thing is to correctly mark the countertop on which the installation is being carried out. If the panel is purchased for a ready-made set, it is worth measuring the available width and thickness in advance, especially when the furniture module is non-standard, created to order. Typically, installation dimensions vary in the range of 55-57 cm. It is worth considering other important points:

• the connection to the pipe should be connected before installing the headset - this will simplify the installation of the nuts;
• installation of the bellows hose should be carried out not through the valve directly, but through a fitting or plumbing drain;
• when forming a connection, a linen winding must be used and coated with gas paste;
• if there is electric ignition, the connection point to the network should be removed in advance;
• to increase the level of safety, you can embed a valve with a thermal shut-off element in the pipe, which is activated when the temperature reaches 80 degrees Celsius;
• the hole cut in chipboard or wood must be carefully coated with sealant along the sides;
• By default, the hobs are supplied with nozzles for the main gas supply; to connect to a cylinder/gas holder, they must be purchased separately.

How to choose the right hose when connecting yourself?

It is important to be aware of the dangers of connection work, entrust this task to specialists, or work independently under the supervision of a qualified gas service worker. The main task is to choose the right hose

Before purchasing it, you need to check it for defects. A certificate must be included with the hose. It is given out in the store

The main task is to choose the right hose. Before purchasing it, you need to check it for defects. A certificate must be included with the hose. It is given out in the store.

You can purchase either a metal hose or a rubber one. The second option costs less than the first. They are usually plain.

Installation nuances

Kitchen hobs are gas, electric and induction. Each of them has its own characteristics and requires a specific approach to installation. But there are general rules that apply to all types of kitchen installations.

Before proceeding with installation, you need to make sure that the following nuances are observed:

• the presence of a ventilation system and an exhaust hood equipped above the stove or the presence of a powerful fan in the window;
• tabletop material with a heat resistance level not lower than 100 °C, and the surface itself is not thinner than 25 mm;
• if you plan to install a panel between two cabinets, make the distance between the walls and the stove at least 15 cm;
• the gap between the wall and the slab must be at least 5 cm, and if it is smaller, then heat-insulating material is laid.

Any discrepancy in the installation of equipment is fraught with its incorrect operation and the occurrence of a fire hazard.

Electrical panel

Electric stoves are especially popular among users. They are easy to use, durable and beautiful. If they break down, you can carry out repairs on your own without calling a specialist. Of course, if you do not have at least minimal knowledge in the field of electrical engineering, then it is better to leave the installation and subsequent repairs to specialists.

On the back wall of any built-in electrical panel there is a diagram according to which the connection is made. If you do something wrong, it can result in a short circuit and incorrect operation of the burners. Some models are equipped with a wire for direct connection of the stove to the panel. This eliminates the need to make an additional electrical point for the socket. Installation in this case consists only of connecting the cable to the panel, installing it in the hole made and sealing it.

Gas hob

The gas stove, built into the countertop, is installed by the owner of the equipment himself. But a representative of the relevant service must make the connection and check the fault.

Typically, gas panels are attached to the countertop using special brackets that come included. After installation, you can connect the power cable and open the gas supply. At this stage you need to be extremely careful and take into account all safety regulations.

You need to make sure there is no leakage. For this, a special gas analyzer or the “old-fashioned” method is used. The joints between the panel and the pipe are lubricated with a soap solution and the gas is opened. If bubbling is visible, there is a problem that needs to be fixed.

Installation rules above the oven

Induction panels have many advantages over gas and electric stoves.

The following advantages can be highlighted:

• the surface quickly heats up to a certain temperature;
• easy to care for and keep clean;
• savings in energy consumption;
• the absence of open flame and too high temperatures makes the equipment safe for children.

When installing a stove above the oven, you need to take into account some subtleties. The oven must be equipped with a cooling system and forced ventilation.

The countertop into which the panel will be mounted must be perfectly flat. If you neglect this rule, then perhaps the deformation will disrupt the normal operation of the equipment, and it will quickly fail.

The main advantages and features of stoves with electric ignition

Naturally, not everyone needs such a function as electric ignition. Many people still use matches or a lighter to light the burners. At the moment, it is unlikely that you will be able to find a stove that does not have an electric ignition function. But there's nothing wrong with that. Prices for stoves with and without electric ignition are practically the same.

In fact, a stove with electric ignition has several advantages:

1. You don't have to run around looking for matches or a lighter to turn on the gas. Moreover, this technique is very easy to use.
2. There is no way you can get burned while lighting the burner.
3. If you have used an electric stove for quite a long time, then the process of getting used to gas appliances will be more painless for you. You simply need to press a button or, as in the case of automatic electric ignition, turn a switch.

Installation work

First of all, you need to determine the type of oven and hob. These elements can be dependent on each other and autonomous. If the first option is chosen, two elements are placed in one niche. In the autonomous version, the hob can be installed in the center of the unit, and the oven in any convenient place where the gas supply hose can be reached.

Connecting the gas oven cabinet and starting it up begins with installing the equipment in the niche of the unit. To do this, the back panel of the niche must be removed and the oven placed on two bars that are pre-attached to the surface of the furniture set. This will ensure ventilation of the oven and niche to avoid fire. Next we connect the electricity. This is necessary for the operation of the fan, electrical control panel and other mains-powered functions.

The next stage is connection to the gas supply system. This installation stage involves connecting the oven cabinet and gas pipe using a hose. It is also necessary to connect the hob to the gas pipeline. In this case, you can use a welded pipe connection. Before starting work, do not forget to turn off the gas supply to your house or apartment.

After the gas oven and hob are connected to the fuel supply, it is necessary to configure all functions of the equipment, check the functionality of the burners and the gas control system. The valve responsible for the gas supply is subject to checking and adjustment.

Detailed instructions for connecting a gas hob and oven are presented in the video.

We follow safety rules

When connecting the oven to the power supply, remember that the wire should never come into contact with the gas pipe. The maximum heating temperature of the conductor should not be higher than 70C. Do not use extension cords or double or triple sockets. All additional wires and connections may cause a fire. Before you start cleaning the oven cabinet, it should be disconnected from the electricity supply.

Before final completion of installation work, it is recommended to check all joints for gas leaks. To do this, use soap foam, which must be applied to the connecting elements. If, when you turn on the gas, the soap begins to foam in some places, it means there is a hole there. Once the crack and leak are repaired, you can safely use the equipment. https://www.youtube.com/watch?v=gZhAjE8tk2k To summarize, we note that it is better to entrust the gas connection to the hob and oven to professionals

In this matter, it is important to take all precautions in order to avoid future accidents. If you decide to make the connection yourself, it is recommended to study the instructions for the equipment from the manufacturer. Also, study in detail the advice of experts

Only with step-by-step installation work, subject to safety precautions, can gas equipment be connected on your own

Also, study the advice of experts in detail. Only with step-by-step installation work, subject to safety precautions, can gas equipment be connected on your own.

Connecting a gas hob with your own hands

Connecting a gas hob is a more labor-intensive and serious process than an electric one. You can do all the work yourself, but you will need the presence of a gas service worker.

Advice. If you are not confident in your abilities, entrust the installation of a gas hob to specialists.

For those who still decide to install the gas hob themselves, step-by-step instructions with photos are offered.

1. Selecting a panel installation location. The hob can be mounted anywhere on the countertop, regardless of the location of the gas communications. Gas is supplied to the hob through a corrugated hose in a metal braid. The limitation of the use of such hoses is the presence of automatic ignition in the gas panel.
2. The hole for the panel is cut out in accordance with its dimensions.
3. After the hole is ready, foam tape should be laid around the perimeter.
4. Only after laying the foam rubber can a gas hob be installed on top.
5. The next step is to connect the panel and the gas line using a hose. Invite a gas service employee to carry out connection work
6. If your panel is equipped with automatic ignition, you will need to connect to the gas supply system. The best option would be to install a separate outlet next to the hob.

When choosing a gas hob, pay attention to the main criteria: surface material, number of burners, location of the control panel and additional functions. The choice of panel material determines how to care for it.

You can connect the gas hob yourself, but the presence of a gas service employee in this case is still required.

What tools are needed to cut the hole?

To correctly connect a gas stove, use the following tools and parts:

• a flexible hose of the required length - universal - about 1.5 m, or individual rubber - from 1 m or more;
• ball valve made of brass with nickel coating, designed for operation in systems that supply subscribers with natural and liquefied hydrocarbon gas of low and medium pressure;
• keys – gas and adjustable keys;
• gasket - usually sold complete with the stove;
• screwdrivers of various types;
• sealing tape or thread - for example, FUM tape or Loktail 55 thread;
• medium concentration soap solution and a brush to check the correctness and accuracy of the connection for leaks.

As soon as all the necessary components are at hand, they begin to work directly.

Installing and connecting a gas hob requires certain tools. To cut a hole for the hob, you will need at least three tools: a milling machine (preferably a manual one), a jigsaw, and a drill. To make the hole perfect, it is best to use a manual milling machine.

You should stock up on a set of screwdrivers. A knife and spatula will come in handy. If you have a set of wrenches, then you need to prepare it too. Every home owner should have a drill.

You should start cutting the hole using a drill. As a rule, you end up with sloppy edges that have to be corrected later. It is better to take drills from 8 to 10 millimeters. Gradually, many holes are made around the perimeter of the future panel. Afterwards, using a drill, a slot is immediately made. It is important to understand that you can only drill from the inside of the countertop.

When a piece falls, it can damage the kitchen unit. It is better to place a chair or cabinet under it. Cutting with a jigsaw is much easier than with a drill. First, you need to use a drill to mark the hole that the person will cut. It is possible to do it without resorting to using a drill.

Care must be taken when installing a gas hob. It is important not to injure yourself or damage the furniture.

Connecting an installed hob

Electrical panel

It is advisable to provide a connection point for the electric hob before installing the kitchen unit. The socket must meet all electrical safety requirements:

• have a grounding line;
• The supply copper cable must have a cross-section of at least 4 square meters. mm.

A hole is cut in the back wall of the base cabinet opposite the electrical outlet of such a size that you can easily insert and remove the plug from the hob by hand.

Sockets installed for self-connection come in two types:

• three-pin;
• four-pin.

If there is a plug installed on the hob cord, then to connect it, just plug it into the outlet. The power cord must be of such length that it is not too tight when connecting the device.

Plugs and sockets for connecting hobs

For models sold without a plug, certain steps will be required:

• If the socket is three-pin and there are four wires in the wire, then you will need to connect a two-phase model to a single-phase network. To do this, wires with black and brown insulation are connected in the cord. This connection is connected to the socket phase. The blue neutral wire is connected to the socket neutral, and the green-yellow wire is connected to ground. All connections must be securely insulated.
• If the placement of the wires in the socket is unknown, then using a multimeter you need to determine the phase and zero. If necessary, they are swapped so that they match the wiring in the plug of the device.

Induction hob

An induction panel is connected according to the same general principles as an electric one. Many models do not have power cords, and only have terminals for connecting an external cable.

The connection diagram is printed next to the terminal block

In this case, the connection is carried out in the following order:

• Remove the protective cover from the back of the device.
• The external cable is passed through the cover.
• The cord is connected to the terminal plate according to the diagram supplied with the panel.
• If a jumper is installed connecting zero and ground, it must be removed.

Gas panel

Household gas is a source of increased danger, therefore special requirements are imposed on the kitchen area:

• Availability of ventilation hood.
• Air flow of at least 2 cubic meters. per hour for each kilowatt of panel power.
• The distance to the wall is at least 130 mm.
• The supply gas hose must be located in such a way that it is not subject to excessive heat and allows for periodic inspection by the inspection organization.

The hob is connected with a flexible hose

The panel connection is carried out by a certified specialist in the following order:

• Sealing fum tape is applied to the threaded connections.
• Paronite gaskets are inserted into the gas hose.
• The hose is connected to the hob and the gas supply point.
• The joints are checked for leaks using soap foam.
• The power cord plugs into a spill-proof outlet.

To operate gas models, they must be accepted by the service organization responsible for this work in your area of ​​residence.

You can install a hob into a kitchen unit on your own, carrying out the work carefully in accordance with the recommendations presented.

How to connect a gas hob.

In appearance, a gas hob looks like a simple device for cooking, which, when connected, should not cause any particular difficulties in performing the work. But it's not that simple. The bottom line is that this type of equipment is connected to the gas transportation system, so work on connecting the hob to gas must be carried out in compliance with all government regulations and technical safety measures. We will try to explain the entire process as correctly as possible, but we strongly recommend that you do not install it yourself, but seek the help of professionals.

You will need:

1. Gas hose;
2. Two adjustable wrenches - maybe gas wrenches;
3. Fum tape for sealing threaded connections;
4. Soap or any other soapy product to check the seal of the connection.

A little theory about connecting the hob.

The hob must be installed in a dry and well-ventilated area. The kitchen must have a ventilation duct to remove combustion products. This exhaust system consists of a grille and a ventilation hood.

The room where the surface will be installed must have good air flow. The amount of air required for the stove is 2 m3/h per 1 kW of burner power. The minimum space from the gas panel to the wall must be at least 130 mm. If this distance is not observed, there is a risk of burning and melting of plastic or furniture.

Step #1. Before you begin installing the hob, be it gas or electric, you need to free and clean the surface around the mounting hole and in the countertop from sawdust and debris. Degrease with soap and wipe with a paper towel. Let dry.

Step #2. Apply a rectangular spacer around the edge of the mounting holes. Press the gasket along all four edges until it fully adheres to the countertop surface. An insulating foam pad is supplied with the surface. Do not use double-sided sticky tape for this purpose. If you lost the adhesive tape when installing the hob, you can always purchase it from the GasService online store.

Step #3. How to connect the hob to gas? It's simple. Pass supply lines such as a gas hose or electrical cord through the mounting holes in the countertop.

Step #4. Slowly lower the surface into the pre-cut hole, ensuring that the edges of the gas panel rest evenly on the gasket on all four edges. A small gap can allow water and other liquids to enter the oven and cause a short circuit. The presence of dampness under the panel can develop mold and peeling of the edges of the furniture.

Step #5. Install the surface clamps onto the threaded bolts so that the long part of the bracket extends under the tabletop. Hold the brackets in place and use your other hand to turn the bolts clockwise until they are fully seated. Don't overdo it and turn the bolt.

Connecting the panel to cylinders containing gas or to an existing gas system, as well as subsequent major repairs of hobs, can only be performed by a qualified specialist who has the right to work with gas equipment in compliance with all safety rules.

Step #6. For a sealed connection to the gas transmission system, fum tape should be applied to all threaded connections, both on the hob and on the gas riser. Insert paronite gaskets into the gas hose on both sides.

Step #7 . Screw the hose connectors to the hob and gas pipe, turn clockwise until the nut stops, then tighten the nut half a turn with a wrench. In this case, you should not make a lot of effort, as there is a possibility of pushing through the paronite gasket and leaving a gas leak.

The gas panel has a pipe threaded connection with a diameter of G1/2”, which is used for connection to the gas system. For liquid gas (propane butane), a hose nozzle Ø 8 x 1 mm is screwed onto the end. The wire carrying the gas must not touch the metal elements of the coating.

Step #8. After installation is complete, the surfaces must be checked for tightness of all connections, using, for example, a soap solution. To prepare a soap solution, mix liquid soap and water in a bucket and stir with a sponge until a uniform foam forms.

Step #9. Open the gas valve by turning the handle of the tap on the lower side towards the stove, so that the handle is parallel to the pipe. Squeeze the sponge and apply foam to the hose. If foam begins to bubble, or if you smell sulfurous gas, close the tap and tighten the nut. Check again, repeat these steps until the leak goes away.

Step #10. Plug the surface's electrical cord into an outlet. Electricity is needed to turn on the electric ignition of the surface. The outlet must be grounded.
