The modern household appliances market provides potential buyers with a wide range of gas stoves. One of the popular purchasing options are combined-type models, where, along with a gas resource, an electric one is also used. However, for buyers of such equipment, connecting a gas stove with an electric oven often raises questions. Do you agree?
Indeed, if you study the rules for handling gas and electricity, you can see that they clearly separate the marked resources. Accordingly, the practice of connecting hybrid gas stoves has some peculiarities. Let's consider these issues in more detail, paying attention to installation standards and rules for connecting to electricity and gas supply systems.
What kind of plug does the combination stove have?
The “cooker” and/or oven with a power of up to 3.5 kW is connected to a standard 16 A/220 V outlet. In most cases, the oven has a regular wire and a 16-amp plug
(if connected independently), so only
a socket
.

Equipment installation instructions
Theoretically, the user himself can install (place) a gas stove on his own. Moreover, each model of a gas stove purchased officially must be accompanied by a user manual. This document specifically describes all the nuances of installing equipment on site.
It’s a completely different matter when the device is connected directly to the gas and electrical networks. Of those nuances of installing equipment on site that are noted in the documentation, one of the first is to ensure proper ventilation of the room where the hybrid stove is installed.
On-site installation of hybrid household appliances is the beginning of an overall effort aimed at equipping the kitchen area with in-demand household appliances
Next, we will consider how to choose a place for installation, taking into account the requirements and features of leveling the hybrid slab.
Requirements for installing a slab
This type of household appliance can be placed in the opening between the elements of kitchen furniture. In this case, on one side of the stove it is allowed to place a piece of furniture whose height is greater than the height of the gas stove. But, according to the rules, such furniture is placed at a distance of no less than 300 mm from the equipment body.
A piece of furniture placed on the other side of the equipment may be placed provided it is at the same height as the stove. If you plan to install some furniture elements above a gas stove, such installation is possible only if there is no impact on the operating process of the equipment.
Based on the rules, for such cases the minimum permissible vertical distance from the surface with burners is at least 650 mm, and the distance to the hood is at least 75 cm.
Configuration for a built-in installation as part of kitchen furniture: 1 – surface level of the equipment; 2 – surface levels of kitchen furniture elements; 3 – minimum distance to the exhaust device (750-800 mm); 4 – minimum permissible distance to the top piece of furniture (650 mm)
Taking into account the same rules for installing equipment locally, certain requirements also apply to pieces of furniture, as well as to walls, partitions, and floors that are located next to heating equipment.
In particular, furniture must have a heat-resistant structure that can withstand heat of 90 °C and above. One thing to take into account is the significant heating of the rear area of the gas stove as the equipment is used.
Optional stand and leveling
Many models of gas combination stoves come complete with a stand. Using a stand slightly increases the overall height (by about 5-10 cm).
The use of the stand is convenient because this piece of equipment is equipped with wheels (two wheels) and adjusting screws (two screws). There are also designs of gas stoves with four adjusting screws.
A clear example of the adjusting support screws included in the design of a household hybrid appliance. Using these design components, it is easy and simple to level equipment
If it is convenient to move equipment with the help of wheels, then by adjusting the screws the gas stove is easily leveled to the horizon or to the level of the surfaces of the furniture set.
Meanwhile, the stand can be removed if necessary. In this case, the adjusting screws are installed directly on the bottom of the gas stove.
Branded online store for LEX equipment
The products of the Italian brand are in great demand among Russians. Reliable household appliances at a reasonable price every day destroy the stereotype that “inexpensive does not come with high quality.” The brand store catalog includes practical hobs (gas, electric and induction) and ovens, dishwashers, refrigerators, microwave ovens, hoods, as well as high-quality kitchen sinks and mixers. On the website you will find original spare parts and accessories for caring for equipment.
A large range of built-in and free-standing models allows everyone to choose the ideal solution for their kitchen. All LEX appliances and plumbing fixtures are covered by an official manufacturer’s warranty for a period of 36.6 months. The long warranty period once again confirms the high quality and safety of the products. Household appliances are delivered by courier service (in Moscow, St. Petersburg, Moscow and Leningrad regions). Delivery of goods by transport companies is possible to other regions of Russia.
Types of hobs
There are two types of slabs:
- Dependent (connected) surface. Its operation can be controlled using handles located on the electric oven.
- Unrelated. Receives power via a dedicated line and is controlled by its own means.
Important! A separate hob and oven cannot be connected to the same outlet. To power each of these devices, its own line is laid. In a combination product with an electric oven and an induction surface, the latter is connected to the oven terminals.

Hood above the burners
Using forced ventilation above the food preparation area has many advantages:
- The odors generated during cooking do not spread throughout the apartment.
- Most of the soot and grease goes into the ventilation, which allows you to make renovations in the kitchen much less often.
- Most modern hoods are equipped with additional functions, the use of which increases the comfort of cooking.
- The hood also provides additional protection in the event of a possible gas leak.
The process of installing a hood in the kitchen is quite simple, but there are several mandatory rules for its installation:
- The width of the hood must exceed the working surface of the stove or be at least equal to it.
- The minimum distance from the burners to the hood is 65 cm. It is better to raise it higher, but so as not to reach for the control panel.
- The hood pipe should have minimal bending.
- The air duct itself should consist of small straight elements.
What will you need?
Connecting the stove to the common gas line is carried out using a minimum of tools.
Keys
To connect, you will need an adjustable wrench, the size of which corresponds to the diameter of the union nut and ball valve.
Ball valve
When installing a gas stove, it is recommended to use ball valves made of nickel-plated brass. Such products undergo a mandatory certification procedure.
FUM tape
Sealing tape (Loctail 55 can be used) is necessary to increase the tightness of the connection between the hoses and the gas pipe and stove.
Concentrated soap solution
A soap solution will be required after connecting the stove. This composition is used to check gas leaks at the hose connections.
Suitable hose
Only gas hoses with the appropriate markings are suitable for connecting the stove. The type of sleeves is selected based on personal preferences and budget.
Screwdriver
A screwdriver will be required to install the socket in cases where the purchased stove is complemented by an electric oven.

Dielectric insert
Special attention should be paid to the use of a dielectric insert. Few ordinary people have heard of this device and know about its purpose.
A dielectric insert is needed to prevent the negative effects of stray currents. In apartment buildings, you cannot be sure that one of your neighbors will not leak current through the gas riser from an ungrounded household appliance. These currents can seriously damage the electrical components of the gas stove - the backlight, electric ignition or control unit. The dielectric insert prevents their transfer through the metal braid of the flexible hose to the household appliance itself.
A dielectric insert is installed between the tap and the flexible hose. Naturally, its threaded connection must also be properly sealed and checked.
Skewer
When using a spit, you need to be extremely careful. Its rod and forks have sharp ends, so there is a risk of injury. It is necessary to insert the holder hook into the hole located in the upper part of the cabinet. Place the first fork on the spit, then thread the meat onto it and insert the second fork. Then you should tighten the plugs using the screws. Place the front part of the spit on the hook of the holder and remove the handle. Place a baking sheet on the very bottom and turn the mode control knob. It should be borne in mind that you can cook products on a spit with a weight not exceeding 5 kg.
Connection rules and steps
The main rule of installation work aimed at connecting household appliances to gas and electricity supply lines is to involve specialists in this matter - representatives of the gas service, electricians.
It is useful for the user to understand how a gas stove with an electric oven is connected to the networks, but in practice this task should only be solved by specialists - service workers who have the appropriate clearance.
Engaging specialists who are authorized representatives of local gas services to connect a household gas hybrid stove is one of the established rules that require mandatory compliance
Each model of gas (combined) stove has technical documentation, which indicates the characteristics of the gas and electrical networks for connection.
Accordingly, resource network lines connected to the equipment installation site must comply with the specified technical characteristics of the equipment.
In particular, we mean the following characteristics:
- gas pressure;
- gas type;
- voltage of the electrical network.
The gas combination stove is supplied for sale, configured for use with natural gas “H”, “E”, supplied at a pressure of 13-20 mbar. Or an installation for the use of liquefied gas at a pressure of 20 mbar can be used. This information can usually be seen if you open the oven door, on the upper or lower end of the body.
Stage #1 - connecting the gas line
Like most classic models, the combined design of the gas stove is equipped with an R ½ nozzle (extended threaded tube). The connection to the main gas line is made using a flexible hose, specially certified for use on a gas stove.
Variations for connecting a gas hybrid stove through a flexible special hose with a centralized supply of natural gas: A – unacceptable option in terms of level relative to the pipe; B, C, D – permissible connection variations
When installing a gas stove with an electric oven and connecting it to the gas pipeline line, the flexible connecting hose should be placed in such a way that there is no contact of the hose body with any part of the stove body.
After completing the connection, it is necessary to conduct a leak test at the joining points.
Additional design of the gas connection point, intended for a liquefied product: 1 – gas stove pipe; 2 – fitting for hose connection; 3 – sealing gasket; 4 – nozzle R ½
Also in the case of a flexible hose connection, the level matching rule must be taken into account. In particular, it is not allowed to raise the body of the flexible hose to the level of the entry point of the nozzle with the R ½ nozzle or above this level. True, if a rigid metal pipe is used for connection, the rule of levels is excluded.
Stage #2 - connecting the electrical line
The location of the electrical connection terminal is the rear wall of the gas (hybrid) stove housing. Typically, the terminals are hidden inside an insulated housing that has a circuit cover.
The box cover can be removed easily - just press the latch with a screwdriver and then push it up. The terminal configuration opens, where the supply cable conductors are connected.
An example of the electrical connection configuration that is widespread in the designs of household hybrid stoves. Terminals L1, L2 are energized. Terminals N and PE – neutral and ground
The connection of the power cable conductors should be carried out according to the markings indicated on the terminal base or on the documentation diagram. In this case, it is necessary to comply with the parameters of the electrical network used - using the correct connection configuration.
Typically, the following color combination of conductors is used on the network cables of combined home ranges:
- Voltage lines (L1, L2, L3) – black, black, brown.
- The neutral line is blue.
- Protective earth (PE) – green-yellow.
After making the connections, the cable body inside the terminal box must be secured, thus preventing possible stretching and breakage. Then close the box lid tightly.
We should also not forget about the need for regular maintenance and performance testing of gas-using equipment. Why do you need to enter into an agreement with the gas company?
Safety
It is very important to be safe if you plan to connect your kitchen appliances to electricity. This is due to the fact that the electric oven has high energy consumption, and because of this it is necessary to connect an additional branch under it using an intact cable with a small cross-section
It is very important to remember that ovens are connected to electricity only by professionals. This is due to the following reasons:
- specialists know all the nuances of this process;
- If the device is damaged due to improper connection to the electrical network, the manufacturer's warranty will become void.
It is worth noting that when operating an oven, the machine is a general safety rule that should be strictly adhered to:
- use exclusively for household use;
- Make sure the electrical wiring is in good condition.
Basic installation rules
After selecting and purchasing a stove, you can proceed to its installation. When choosing an installation location, you must adhere to some rules:
Structure of flexible gas hose.
- Installation of this equipment should be carried out at a distance of no more than 4 m from a rigid gas pipeline.
- A dielectric insert is used between the flexible hose and the gas tap to prevent static discharge.
- Modern stoves are equipped with electric ignition and oven lighting. To use them, a supply voltage is required. If there is no socket with reliable grounding in the kitchen near the installation site of the stove, you need to conduct the electrical wiring yourself using a three-core cable with a core cross-section of at least 1.5 mm.
Kitchen heating pads are connected using flexible hoses. This installation method is the most optimal today. In this case, the plate will not be rigidly attached to one place, because the flexible hose will allow it to move within a few meters. This will make cleaning the kitchen much easier. In addition, such a gas stove connection is safer than a hard one. If you accidentally move the slab, the hose will serve as a kind of shock absorber that will not disturb the existing fastenings.
Rubber hoses for gas connections are made up to 5 m long. You need to purchase hoses with a white metal braid with yellow marks, since the presence of red and blue marks indicates that such hoses are used for supplying water.

The choice of hoses is quite wide. The main types are the following:
- Rubber-fabric sleeve, which is softer and more flexible than other types, but inferior to them in rigidity. It is worth noting that such a sleeve is a dielectric, which will allow you to do without a dielectric insert when connecting.
- The rubber hose in a metal braid has medium rigidity and greater protection from mechanical damage.
- A metal bellows hose, which is the best option when connecting gas equipment, as it is recommended by regulatory documents and is the most durable and resistant to gas pressure. Its only drawback is the relatively high price.
You only need to purchase a gas hose that is certified
In this case, special attention should be paid to its output, which should correspond to the outlet on the stove. If the stove has a direct outlet, then you should choose a sleeve with an angle
Also, do not forget about the threaded connection. The standard thread size is 1/2′, so if the threaded connection is 3/8′, then you need to buy a special 1/2′ adapter. Such an adapter can be included in the kit.
Service cost
There is no clear tariff for installing a gas stove. The cost is calculated individually by specialists. Therefore, it is extremely problematic to say how much Mosgaz will charge you for installing new equipment. Pricing depends on the region and complexity of the work. On average, the cost varies in the range of 1000-3000 rubles. Payment will be charged to you only after the new stove is installed in the apartment.
Keep in mind that if you use the services of a store or a certified commercial organization, whose employees will install the stove taking into account all the standards, you will still have to call city gas workers. In this case, you will have to pay extra for their departure.
Normative documents
Steel
- Which regulatory document must a steel gas pipeline comply with?
- What are the requirements of this standard?
I will highlight the key points of his text.
The diameter of the pipes can vary from 6 to 150 mm.
Gas distribution throughout the apartment is carried out using pipes DN 15 and DN 20.
There are light, ordinary and reinforced pipes. They differ in wall thickness. The thickness, depending on the diameter and type of pipe, varies from 1.8 to 5.5 mm.
The material is shipped in straight lengths from 4 to 12 meters. With a diameter of up to 20 mm, pipes in theory can be supplied in coils; in practice, I have never encountered this form of delivery.
The pipe can be made of black steel or galvanized. Zinc anti-corrosion coating greatly increases the service life of the gas pipeline. Suffice it to say that I have more than once opened heating risers assembled from galvanized steel in steel buildings, and after half a century of operation they were in no different condition from new ones.
The zinc anti-corrosion coating makes the material almost eternal.
At the customer's request, it is possible to cut threads at the ends of straight sections with a diameter of more than 10 mm.
The ends of the segments are cut off at right angles to their longitudinal axis and cleaned of burrs. The bevel of the end should not exceed 2 angular degrees, the size of the remaining burrs should be 0.5 mm.
Hydraulic tests are carried out at pressure:
- 25 kgf/cm2 for ordinary and light pipes;
- 32 kgf/cm2 - for reinforced ones.
All VGP (water and gas) pipes are electric welded. They are produced by folding a flat strip and welding the seam, followed by calibration.
Stainless steel
- What GOST is used to produce corrugated stainless pipes?
Manufacturers of corrugated stainless steel mention GOST number 10705-80 in their documentation. It describes the technical requirements for the production of longitudinal electric welded pipes with a diameter of 10 - 530 mm.
Calculation of network capabilities in an apartment
Before undertaking such a complex and important task as connecting an electric stove in an apartment or house, it is important to think through every detail. It wouldn’t hurt to familiarize yourself with the technical specifications, power line laying standards, etc.
Before you start directly connecting and working with electrical wiring, you should choose the right place for the stove.
Stove line
When considering a tile line, it is worth considering that it must be installed according to the technical specifications. They indicate that the wire should run perpendicularly up above the entry point, then turn to the side 20 cm from the ceiling. A line is drawn parallel to it to the exit point so as to enter it perpendicularly.
The place where you plan to install the stove must be level, so that when adjusting with the legs, its stable and stable horizontal position is ensured.
What cord is needed
The cord must be three-phase, have a high-quality cable duct and be of sufficient length to properly secure the line. In a cut, its area according to the rules is 4 mm square (up to 12 meters in length), and with a longer duration you will need a 6 mm square cable.
The length of the wire should be generous so that, if necessary, you can easily move the household appliance away from the wall without removing the plug from the socket.
Protective devices
It is recommended to install both an automatic circuit breaker and an RCD, as they will protect the device from voltage drops and the consequences of a violation of the integrity of the cable - a short circuit
But it is important to choose them correctly; the automatic device should correspond as much as possible to the highest capabilities of the electrical device, and the RCD should be a level higher than it
It is better not to place other electrical appliances near the stove - the electromagnetic field can negatively affect their operation.
Check the power of all electrical appliances
This information is on a label on the back; if you haven’t purchased the equipment yet, take the average values for such a device or specific ones - on the manufacturer’s website.
Article on the topic: Which cookware is suitable for a gas stove
All this will help the electrician calculate the load on the network, the number of distribution boxes and cable thickness. This is especially important if you live in apartments - they are not subject to load standards adopted by SNiPs for residential premises; if there is not enough power, you will have to resolve this issue with the management company and power supply engineers.
The hood connection is made inconspicuously; at medium height - four sockets: enough space for appliances that will stand on the countertop
As a rule, kitchen electrical appliances require 10–15 kW of power, but you need to provide at least another 30–50% of the reserve; that is, the electrical wiring in the kitchen should be designed for approximately 20 kW of power - this will protect you from the risks of short circuits and from power surges, which can cause equipment to burn out.
Conclusions and useful video on the topic
The video below demonstrates step-by-step installation of the equipment. The video touches on certain nuances of installation, compliance with rules and regulations:
Installing a household hybrid gas stove complemented by an electric oven is, by and large, not difficult. Another question is that the connection of this type of equipment should be carried out according to specially established rules that determine safety issues. Therefore, it is not possible to carry out the connection work independently (prohibited by the rules), even if you have some skills, knowledge and ability.

Requirements for installing a gas stove with a cylinder
Not every country village has a gas pipe, but gas stoves are still used. The fuel source in this case is cylinders filled with propane. Gas is pumped into them under high pressure, so a reducer is installed on the cylinder to reduce this pressure. Its proper operation is a guarantee of safety. Therefore, it is important that the gearbox is checked by a technician before installation.
Attention! Not all gas stoves can operate on bottled gas, which the manufacturer must note in the product data sheet.
A strict requirement is the distance from the stove to the cylinder, which should not be less than 1.5 meters. Experts recommend installing cylinders outside the kitchen area. To do this, you can use an extension or a canopy. It is important that the room where propane cylinders are installed is well ventilated. Since when replacing cylinders the gas supply hose is unscrewed and tightened, after each operation the connection is checked for leaks using a soap solution.
And one more point regarding the correct laying of a pipe or hose. For safety reasons, gas-carrying lines are required to be located in open space. You cannot put them in closed niches or boxes, under false walls and panels, so the best option is to lay a horizontal section from the riser to the appliance under the kitchen countertop. The hose is attached to the wall using clamps or clips.
