Basic requirements for installing a gas boiler

Correct calculations

The upper and lower cabinets of the kitchen set are an indispensable component of any kitchen, and a huge kitchen-studio with a dining area, common in elite new buildings, and small and cramped in a standard Khrushchev. Before looking at alluring photos of kitchen furniture in glamorous magazines and planning a purchase, you need to weigh all the components of the choice.

Distance with gas stove

They include not only modern design, finishing materials and the number of items. They also take into account the growth of the main user, the height of the ceilings in the room, the footage on which all this will have to be installed.

There are a lot of publications on the topic of ergonomic equipment for a small space in the kitchen.

Dishes in the upper drawers

These standards are the result of scientific research, experiments and measurements. At the same time, each distance is provided for a specific purpose and carries its own semantic load.

Standard apartment

The main standards are aimed at creating optimal conditions for working in the kitchen:

1. A wall cabinet in the kitchen is recommended to be placed from the floor at a height of 1.9 meters, regardless of the height of the ceiling. This allows the hostess to reach the desired item at the top without resorting to auxiliary devices - a low stepladder, a stool, a small bench. You can deviate from this rule only when the height of the main user is much higher than average. This height makes it easy to inspect all the contents and get the necessary items without much effort.
2. The floor part of the kitchen wall should be located at a distance of at least 0.6 m from the bottom of the hanging part. Compliance with this condition will allow not to perceive the upper cabinet in the kitchen as an obstacle to work or to place household appliances in the formed space for working in the kitchen.
3. The standard distance of the bottom of the kitchen cabinet from the floor is 1.5 meters. Simple calculations show that with a height of 90 cm of the lower item, the headset is easy to maintain both the space above the countertop and the required distance from the floor. However, recent statistical studies have shown that the majority of users not only do not follow the rules on how everything should be placed to work in the kitchen, but also do not know about their existence.

Lower and upper cabinets set with gas stove

These are standard settings that are commonly used to create the comfort of adult family members. But with individual planning, it is quite possible to make deviations from them.

The small stature of the hostess or the tall one, who spends a lot of time in the kitchen, provides that the numbers vary for the most rational placement.

The distance between cabinets in the kitchen is a prerequisite for productive work. Their placement closely deprives the hostess of a significant functional space between the countertop and the hanging part.

Kitchen set

An incorrectly chosen distance between the cabinets can lead to permanent injuries or the development of diseases of the spine due to the need to take an uncomfortable position when working.

Accurate calculations with non-standard growth rates will allow you to properly organize the workspace in the kitchen, then you will have to get tired much less. Therefore, all distances must be verified.

Removing the old boiler

Having received all the required documents, the company, in the presence of a certificate for such work, can begin to replace the old boiler. You can significantly speed up the replacement work by dismantling the old boiler yourself, which is not prohibited by law.

To remove the old boiler, do the following:

The procedure for installing a gas stove

Before in place, the plate is pre-unpacked. Inside it are accessories - grills, baking sheets, etc. All this must be removed. After that, you should first screw those same adjusting legs. This work should be done by two people. And for convenience, and so as not to damage the surface of the plate.

When connecting the stove, it is more convenient to use a special high-pressure flexible hose. It can be bought in any specialized department, and it is not expensive. The hose, unlike a metal pipe, allows, if necessary, to move the stove within small limits. This is convenient for some small repairs (laying linoleum, for example). It is good to attach special clamps to the wall behind the stove in advance, which will hold this hose in a fixed position.

Be sure to read the instructions for your stove, as each model has its own characteristics.

Gas stoves are popular products because they are easy to use, compact in size and easy to install.

The installation of a gas stove can be done by everyone, since this work is considered simple, but it is important to take into account certain nuances, without which you can get a poor-quality result.

Why keep a distance between the outlet and the gas pipe

Typically, a 220-volt AC outlet for powering electrical appliances and gas pipes is located in the immediate vicinity in the kitchen or at the connection point for the gas boiler of an individual house. A typical malfunction of an electrical outlet is the loosening of the fixing screws on the terminal block during operation, as a result of which the wire moves away from the contact plate for a short distance and a spark may appear between them.

If at this time, for some reason, a long-term gas leak occurs from the gas pipeline, then when it reaches a certain concentration, an explosion may occur after it enters the sparking zone. A similar danger is represented by sparking not only in the socket, but also in the break of electrical wires, connected electrical appliances, shields placed next to the gas pipe.

Connecting a gas stove safety rules

Natural gas used for cooking in communal houses is highly explosive, so compliance with safety rules when working with gas is the main condition when working with gas-consuming equipment. The connection of the stove to the gas supply system is carried out taking into account the following requirements:

1. For gas supply in the household, special flexible hoses made of various materials are used, bearing a manufacturer's tag indicating the date of manufacture.

Rice. 2 Gas stoves with gas pipe connection

1. The rules for connecting a gas stove in an apartment regulate the length of the hose, which should not exceed 4 meters, if it is necessary to take the stove to a greater distance from the gas supply pipeline, shut off the gas supply and weld a piece of metal pipe of the required length to the main.
2. A flexible underwater hose is mounted in an easily accessible place, trying not to block it with non-separable building structures; connection requirements do not allow the use of two segments with any type of connection.
3. If the hose in the visibility zone does not have a very aesthetic appearance, it is pasted over with a self-adhesive film or paper; it is forbidden to use any paint that can damage the polymer surface of the eyeliner.
4. Some modern gas hob ranges have built-in electric ovens with powerful heaters. In this case, a separate network is organized for the supply of electricity with its own RCD protective shutdown device. When placing it, you should follow the rules for the operation of PES electrical installations, which regulate the following parameters:

• The distance from the electrical outlet to the gas supply pipe must be at least 500 mm.
• The gap between the power cable of the stove and the gas pipe must not be less than 100 mm.

Rules for connecting the stove in the apartment

When using a stove in an apartment, it is better to entrust its connection to specialists of gas supply services and organizations with whom you must first conclude an agreement for the supply of natural fuel with the opening of a personal account to pay for services. An agreement is usually required when acquiring a new apartment as a property, the list of documents that are generally needed to connect a gas stove in compliance with all standards is as follows:

1. Certificate of ownership of the apartment and a certificate confirming the state registration of housing.
2. Registration certificate for the apartment.
3. The old contract for the maintenance of the stove and the subscriber's book, if any.
4. Passport for the installed stove and gas meter.

The documents collected by the homeowner are submitted to the gas service, after which its specialists issue forms for filling out a gas supply agreement. After filling out the paperwork and instructing on the operation of gas installations, the contract is signed by both parties with the issuance of permission to connect the equipment.

Rules for connecting a stove in a private house

If in a city apartment the duties of specialists of the gas supply service, with which the owner has concluded a contract on a voluntary-compulsory basis, include a mandatory check of gas equipment at least once every six months for the safety of the whole house, then in the private sector the situation is different.

Here, the homeowner independently decides on gas supply, he can connect to the central gas pipeline and conclude an agreement with the relevant services, by analogy with apartments, or use autonomous gas supply with cylinders and gas tanks.

With the latter options, it is most likely that you will have to connect the gas stove yourself or with the involvement of hired specialists without any guarantees. Therefore, the matter should be approached with full responsibility and carefully study the technologies in order to choose the right components and carry out high-quality installation.

Rice. 5 Arrangement of gas hoses

Installing a new gas stove

The whole process is carried out in several stages:

• the gas valve is closed, and at the same time its handle should be raised to the very end;
• the old stove is disconnected from the gas pipeline and taken out of the room;
• a new plate is installed in the right place, and at the same time it is impossible to remove the protective film from the product so that it is not damaged during installation, and the plate must stand evenly and securely, since any distortions or wobbles are not allowed;
• all the components of the equipment are disassembled, and it should also be remembered that the stove must be at a certain distance from walls and other objects so that it can be easily connected to the gas pipeline;
• in the assembly, which is located at the junction of the product and the hose, you need to mount a special gasket that will protect the stove from various contaminants;
• the connection point must be tightened well, for which two open-end wrenches are usually used;
• the plate is installed at a certain distance from the wall, and this distance should be the same as indicated in the regulatory documentation for the product, and at the same time, its evenness must be checked using a special building level;
• if the product contains elements that operate on electricity, then it must be connected to the electrical network, for which a suitable cable is used, and it is also often necessary to install a power outlet;
• the last step is to install all the additional elements of the gas stove that are sold complete with it, and the protective film is removed from the product.

Underground

The distance from the house to the gas pipe in the embankment cannot be less than 5 m. There are special provisions of SNIP, according to which the distance can be reduced by 50%, but they are regulated by the terrain and the passage of the gas pipeline. For example, laying pipes between houses, arches, in very limited areas, etc.

The distance to the gas pipe of the outer walls of the well, chambers or other equipment of engineering networks should not be less than 30 cm. The laying must be carried out in compliance with the technical requirements and conditions. Only this can be a guarantor of security. By the way, that is why an independent transfer or organization of a gas supply system is not allowed.

The distance to air communication lines, as well as external electrical networks, cannot be less than 2 meters. The same applies to the gap between the gas pipeline and the heat transfer channels. The distance from the gas pipe to the fence, taking into account the underground laying of the highway in the villages, should be at least 50 meters. SNIP provides for a reduction in the gap, but only when taking into account certain norms prescribed in the regulations.

The depth of laying the gas pipeline should exceed 0.8 m for roads and roads with heavy passenger traffic and 0.6 m for roads with low traffic.

Product installation rules

When installing a gas stove, it is imperative to follow certain rules. The product itself must be located at a specific distance from the gas pipeline, and this distance is approximately 4 m. In this case, a special dielectric insert must be mounted between the hose and the gas pipeline valve.

Modern gas stoves, as a rule, come complete with oven lighting, as well as with electric ignition, with which it is very convenient and easy to use the stove. All these elements must be connected to the electrical network, so for this you sometimes need to install a special euro socket, which must be grounded without fail.

Before direct installation, you need to decide which hose will be used for flexible wiring of the product. To do this, there are quite a few options, each of which has specific characteristics. The installation of a gas stove in the house can be carried out using rubber-fabric hoses, which are a sleeve with good flexibility and softness.However, at the same time, it does not have a very good level of rigidity and strength, so it will not be able to withstand mechanical stress.

You can also use a rubber hose, which is supplied with a special metal braid. This option is considered the most optimal for installing the product in an apartment, since with its help the connection is safe and easy. In the store, you need to choose a hose that is specifically designed to connect to the gas pipeline, and at the same time it differs from the hose for the water supply system with special yellow marks on the braid.

Additionally, there is a hose, which is a bellows metal hose, which has unsurpassed rigidity, therefore it is considered the most reliable of all options. At the same time, it has a rather significant cost, which is justified by the safety of its use and long service life. It is ideal for installing a gas stove, as it is indicated in all regulatory documents.

You can choose absolutely any type of hose, and at the same time it must have a suitable diameter, which should be 10 mm, but a larger indicator is allowed. If a thin hose is used, then during the gas supply it will not provide an efficient and optimal gas supply to the stove. If a hose is used that contains metal, then special dielectric inserts must be used for it, which will act as insulating elements.

Placement of the gas stove relative to gas and electrical communications

Household gas appliances are modern, high-quality, complex technical devices that, on the one hand, help us in everyday life, on the other hand, are dangerous when used for their intended purpose.

Gas is a substance without color, smell, taste, and a person cannot determine its presence with his senses, while it is a dangerous flammable substance, since a large amount of energy is released during its combustion.

In this article, we will consider the requirements for installing gas stoves in residential premises.

There are several types of household gas appliances.

• A gas stove is a device that is designed to cook food directly on the stove. Appliances include from one to four burners. Cookers are available with or without an oven.
• Geyser - designed to heat water in a residential area. The columns are automatic (they ignite on their own and maintain the set water temperature), semi-automatic (they require adjustment depending on the water pressure, and so on), manual (each time you need to manually start the column and monitor its operation).
• Gas boiler - designed to work in the heating system of the room, if the boiler is single-circuit, and for heating and heating running water - if it is double-circuit.
• Gas burners for heating stoves - the name itself speaks of the purpose, that is, for heating a room using brick stoves.
• Gas metering devices - designed to fix the amount of fuel pumped through them. For the consumer, this means the amount of substance used.

Currently, the requirements for the installation of gas equipment in apartments, cottages, residential private houses in the Russian Federation are not provided for by any regulatory legal act. When designing the location and installation of such devices, they are guided by the installation and operation instructions that come with the equipment.

Compliance with these requirements is very important, primarily because the safety of our existence depends on it, and if it is an apartment building, then the people around us. Gas explosions and fires are highly destructive in nature.

The norms under consideration can be gleaned from SNiP 2.04.08-87, which was valid until 2002. This act provides that the distance to the boiler when installing a gas stove in residential buildings and apartments must be at least 50 cm.

And also the stove should be located next to the boiler, but under no circumstances under it. And you should not put a stove under the column either.

At the same time, the location of gas appliances among themselves should not be at a great distance from the hood, which must be mandatory and perform its functions (be cleaned).

The hood ensures the removal of combustion products, mainly formed carbon monoxide, which is not felt by a person in any way and is fatal even in small concentrations. Accordingly, the room, in addition to the hood, should have opening windows for ventilation.

Before the pipe that delivers gas to the room, the location of other devices is not regulated. And also there is no regulation for the installation of electrical outlets in the kitchen with a stove.

note

However, hanging sockets or other objects directly above the device is not recommended categorically, since during the use of the device a large amount of heat is generated, and objects located above it can melt, catch fire, or simply become unusable due to exposure to high temperature.

The only thing that can be placed above the stove is the electric hood receiving device, which is designed to work at high temperatures.

It is not difficult to connect gas appliances and, in particular, the stove yourself, if you follow the conditions of the operating instructions

However, before installation, it is important to turn to professionals to develop a project, if there is none, and then turn to them to carry out the work, since errors during installation and commissioning of this kind of equipment are very expensive for consumers.

In conclusion, I would like to note that gas appliances are very complex equipment, the misuse of which can lead to tragedy, which is confirmed by the numerous explosions of residential buildings in Russia and in the world, taking away the lives of innocent people. One makes a mistake, and many suffer. Remember - gas is not safe!

Rules for the placement of pipes and sockets in relation to the gas pipe

Often the cause of emergencies and emergencies is a violation of the simplest safety rules for installing electrical wiring, one of which is the norms for the distance of electrical wiring relative to pipelines.

The set of rules for the installation of electrical installations (PES) developed by specialists of the Ministry of Energy allows you to fully answer the question: at what distance from the gas pipe can you lay a cable and install an electrical outlet.

The distance from the electrical outlet to the gas pipe - what regulates the norms

The rules for the safe installation of electrical wiring are regulated by the main regulatory document - PUE-6, they apply to installed and operated electrical installations with AC voltage up to 750 kW. The rules are developed taking into account the implementation of planned and preventive tests, repairs of electrical installations, over which technical supervision is established.

Rice. 3 Selection criteria and methods for laying open electrical wires and cables

Rules for placing pipes and electrical cables

When installing electrical networks, internal and external wiring is distinguished, in the first version it is placed in the structure (strobes) or niches of building structures and is separated from the surface by fireproof materials - concrete, plaster, cement-sand mortar, alabaster, gypsum binder.The thickness of the insulating layer of hidden wiring from non-combustible building materials is regulated by the PES only for the cases of nearby products from combustible components, according to the rules, the insulator layer should not be less than 100 mm.

PES regulate in more detail the norms of open wiring distances to pipes through which explosive gases circulate. As required by regulatory documents (PUE-6 clause 2.1.56), the allowable distance in the light between electrical wires without protection or in protective insulation and pipes with neutral substances must be at least 50 mm. If explosive gas passes through the line, the clearance is made more than 100 mm .

If the distance from the electric cables to the pipes is less than 250 mm, it is obligatory to protect the wiring from mechanical influences for a length of at least 250 mm on both sides of the gas pipe.

When laying an electric cable and pipes with a neutral working substance in parallel, the gap between them is made at least 100 mm. If the electric line runs next to the gas pipeline, the distance between the gas pipe and the wire must be more than 400 mm.

If the design of the premises includes the intersection of laid hot pipelines with electrical wiring, the latter must have a suitable heat-resistant insulation design or have external protection against high temperatures.

Rice. 4 Wiring installation methods depending on the type of premises

When carrying out repair work in an apartment, a situation often arises when you need to move an electrical outlet in the kitchen or lay new wiring. In this case, electrical installation work must be carried out in accordance with generally accepted requirements and rules (PES), developed by specialists, taking into account repeatedly tested safety standards.

What should be the distance from the gas pipe to the building

Gas is the most affordable and therefore the most popular energy resource. It is used as fuel for the vast majority of heating systems and, of course, for kitchen stoves and ovens.

table

It is supplied in two ways: through the gas supply system or in cylinders.

Gas lines

The cost-effectiveness of this solution is obvious. Firstly, a much larger number of objects are covered in this way, and secondly, it is impossible even to compare the volume of gas transmitted through pipes with what is supplied in cylinders. Thirdly, the level of safety of the gas pipeline is much higher.

For domestic needs, high-calorific gas is used, with a calorific value of about 10,000 kcal/Nm3.

The gas is supplied under various pressures. Depending on its size, communications are divided into three types.

• Gas pipeline with low pressure - up to 0.05 kgf / cm2. It is being built to supply residential and administrative buildings, hospitals, schools, offices, and so on. Almost all urban utilities fall into this category.
• Communications with medium pressure - from 0.05 kgf / cm2 to 3.0 kgf / cm2, are required during the construction of the main city boiler houses and as highways in large cities.
• High pressure network - from 3.0 kgf/cm2 to 6.0 kgf/cm2. Arranged to provide industrial facilities. Even higher pressure, up to 12.0 kgf/cm2, is implemented only as a separate project with appropriate technical and economic indicators.

In large cities, a gas pipeline may include communication elements of low, medium, and high pressure. The gas is transmitted downstream from the higher pressure network to the lower one through regulatory stations.

Communication device

Gas pipes are laid in different ways. The method depends on the task and features of operation.

Underground communications are the safest way of laying and the most common.The laying depth is different: the gas pipeline transmitting wet gas should be placed below the freezing level of the soil, gas pipes moving the dried mixture - from 0.8 m below ground level. The distance of the gas pipeline to a residential building is standardized by SNiP 42-01-2002. The gas pipe can be steel or polyethylene.

• Ground systems - allowed in case of artificial or natural obstacles: buildings, waterways, ravines, and so on. A ground device is allowed on the territory of an industrial or large communal building. According to SNiP, only steel gas pipelines are allowed for above-ground communications. The distance to residential facilities is not set. Pictured is an onshore gas pipeline.
• Internal networks - the location inside the buildings and the distance between the walls and the pipeline is determined by the installation of consumer objects - boilers, kitchen equipment and so on. It is not allowed to lay gas pipelines in strobes: access to any section of the pipe must be free. For the organization of internal networks, steel and copper products are used.

In suburban areas, the construction of a ground version is commonplace. The reason is the cost-effectiveness of such a solution.

Permissible distances

SNiP 42-01-2002 determines the distance between the house and the gas pipe by the magnitude of the gas pressure. The higher this parameter, the greater the potential hazard of the gas pipeline.

• A distance of 2 m is maintained between the foundation of the inhabited house and the low pressure gas pipeline.
• Between gas pipes with an average value of the parameter and the structure - 4 m.
• For the high pressure system, a distance of 7 m is set.

The distance between the house and the elevated structure is not regulated by SNiP. However, it establishes a security zone around the land gas pipeline - 2 m on each side. The zone must be highlighted. Accordingly, when building a house, compliance with this boundary should be taken into account.

Building rules regulate the placement of the gas pipe relative to the window and door opening - at least 0.5 m, as well as the distance to the roof - at least 0.2 m.

SNiP recommendations for gas pipelines are based on fire safety requirements and sanitary standards, so their implementation is mandatory.
