Competent installation of a wall-mounted gas boiler in a private house. Installation of a wall-mounted gas boiler: a canopy of a gas boiler and preparation for connection Wall-mounted gas boiler DIY installation

In a modern private house, you cannot do without a gas boiler. It is simple and safe to operate. Yes, its installation is very laborious and expensive, but in the end, a gas boiler is the most cost-effective solution for heating a house and heating water. Compared to electric heaters, it can pay off in one winter.

Gas boilers can be single-circuit and double-circuit. Single-circuit are intended only for heating, double-circuit - for heating and water heating. Also, gas boilers differ in power and type of installation.

It is very important to be correct determine the required power equipment. The disadvantages of insufficient power are obvious. Excess capacity, in addition to the economic component, is also dangerous. Acid condensate forms in the combustion chamber due to frequent temperature changes, which can corrode the metal parts of the boiler.

The boiler output is in direct proportion to the size of the room. You also need to make allowances for the climatic conditions in which you live. Divide the area of ​​heated premises by 10, and multiply by a factor of 1.2 - 1.5 for the Moscow region, 0.7 - 0.9 for the southern regions, 1.5 - 2 for the northern regions - and you will get the required capacity. Thus, for a house of 100 square meters located in the Central Region, an apparatus with a capacity of not less than 12-15 kilowatts.

The power can be adjusted. Low-power boilers have one-stage power control. Medium capacity heating devices are equipped with two-stage regulation. High-performance boilers are equipped with modulated power control.

By the type of installation, wall-mounted and floor-standing boilers are distinguished. Each type of installation has its own characteristics. But, no matter what boiler we install, before its direct installation, it is necessary to fulfill a number of requirements that are established by certain SNiPs.

For devices that are installed on the territory of the Russian Federation, the requirements are determined by SNiPom 41-01-2003 "Heating, ventilation and air conditioning", SNiPom 31-01-2003 "Residential and multi-apartment buildings", SNiPom 42-01-2002"Gas distribution systems" and other regulations.

Rules for installing gas boilers in a private house

Premises

Requirements for parts and parts of equipment

Gas vents (or, as they are often called, chimneys)

  1. The path for the removal of combustion products must be separate from the usual chimney.
  2. Horizontally, its length in the boiler room should not exceed three meters.
  3. The gas outlet can have no more than 3 bends.
  4. The diameter of the flue gas outlet and the power of the boiler must correspond (with a power of up to 30 kW D = 130 mm., With a power of 40 kW D = 140 mm.)
  5. The diameter of the flue must not be less than the diameter of the opening for connecting the flue.
  6. The outer end of the flue must be at least half a meter above the level of the roof ridge.

In modern boilers with a closed combustion chamber, so-called coaxial flues that are sold and installed together with the heating appliance. When installing such boilers, the dimensions of the room are not important either, since the combustion air does not come from it, but from the street.

These general requirements may differ slightly in different regions, they are constantly being improved and refined. In addition, there are nuances that the gas supply in the house is not central, but balloon. In this case, the rules and requirements for installing a gas boiler will differ in some features. There is also a difference in what material the house is built from, what the floors are. To avoid problems at the stage of project approval, it is better to invite a specialist and inspect the house in advance for possible shortcomings.

What actions need to be taken to obtain permits for the installation of a gas boiler:

Agreed project and is a permit document for the installation of a gas boiler.

Mounting

Installation sequence for floor standing boiler

  • The boiler is installed on a solid foundation that can withstand its weight. For this, either a concrete screed is poured, or a sheet of galvanized iron is laid on the floor.
  • When placing the unit on a base, make sure that it is exactly parallel to the ground.
  • Connect to the chimney and check the draft.
  • Connect to the pipes of the heating system, while installing a hard water filter (after the outlet line before entering the boiler return line). Place shut-off devices (eg ball valves) on both sides of the filter. Install ball valves on all connections.
  • Double-circuit boiler connect to the water supply... It is better to make an insert into the water supply system as close as possible to the entrance of the pipe into the building or to the place where the pipe branches. It is better to connect the water supply pipe from the top, the water return pipe from the bottom.
  • Connect to gas pipeline. This can only be done by a gas master; you cannot make a tie-in yourself.
  • Connect to power supply.

In both installations, the system must be filled with water before the first start-up. To do this, the device must be turned off. Water should be drawn very slowly - this is the only way to get rid of air "bubbles" in the heating system.

It should also be remembered that the installation of any gas equipment cannot be carried out at sub-zero temperatures, the temperature must be from 5 to 35 degrees.

Maintenance of gas equipment

Maintenance of gas equipment should be carried out regularly, at least twice a year. Be sure to do this before the start of the heating season. A specialist must check the tightness, the condition of the chimney and the ventilation system, clean the filters and the burner, and replace worn parts.

It is not uncommon that many private houses do not have centralized heating and water supply. For this reason, the owners themselves have to solve such issues. Wall mounted gas boilers can come to the rescue. How to correctly install a wall-mounted gas boiler with your own hands? How much does it cost to install a gas boiler?

Today they are presented on the market in a huge number and variety of brands. There shouldn't be any problems with their choice. However, it is worth deciding how to mount the boiler - on your own or with the help of qualified specialists? The latter option is not bad, but you have to spend extra money as payment for employees.

The room in which the boiler will be located must have a window for ventilation. The door to the room should open outward. The room must have an area of ​​more than four square meters. The ceiling should be two meters or more. As for the doorway, its width must be at least 800 millimeters. A prerequisite for a boiler room is the presence of a working ventilation duct. Often, wall-mounted boilers are located in utility rooms, kitchens or storerooms.

Another important condition is pasting the wall where the unit will hang with non-combustible materials. This action will eliminate the likelihood of a fire that could arise from a spark hitting combustible materials. Modern non-combustible products will harmoniously fit into the design of the room without spoiling the interior.

When buying a boiler, you need to acquire an official certificate, because in the absence of this documentation, registration of heating equipment will become almost impossible. Also, the certificate will allow connecting the equipment to the gas supply system.

Even when choosing a place for the unit, you need to think about installing an exhaust hood for a gas boiler. Old chimneys can be used, and if they are not available, new chimneys will need to be installed. Most often, the combustion product removal system comes complete with the boiler itself.

Compliance with these rules for installing a gas boiler is vital.

Some tips for installing boilers

One of the most important stages in the installation of gas heating boilers is their connection to the gas supply system. In order for the regulatory authorities to give permission for it, it is necessary to carry out the installation and installation of the gas boiler strictly in accordance with the recommendations and requirements that the technical passport has. Otherwise, you will have to redo something, if not everything.

When installing the gas boiler "Navien » , as well as the installation of the Immergaz gas boiler, it is important to check whether its capacity corresponds to the capacity of the entire heating system. When connecting the boiler to the old heating system, it is imperative to clean and flush all pipes, which will eliminate the likelihood of clogging in the near future.

It is necessary to think over in advance the entire installation scheme for a wall-mounted gas boiler. It should provide for water treatment to supply the hot water system. The inlet to the unit must be equipped with a purifying and metal-trapping magnetic filter.

One of the worst enemies of the gas boiler, and indeed of the entire heating system, is corrosion. Therefore, in order to avoid its appearance, it is better to start installing a closed loop, which will prevent air from freely entering the system.

Installation rules

  1. The wall-hung gas boiler must be fixed to a load-bearing or solid wall.
  2. During the installation of the Ariston gas boiler, you need to ensure that the hood and chimney are proportionate.
  3. The unit must be easily accessible so that timely maintenance can be carried out and the replacement of parts in the event of a breakdown can be made freely.
  4. If the boiler is installed inside the cabinet, it is necessary to provide a five-centimeter distance from the cabinet partition above the equipment. This free space will make the nodes at the top accessible so that any maintenance work will be possible.

Boiler installation technology

Before directly installing gas equipment, you need to tackle the chimney hole.

It will be much more convenient to perform installation if you use a special cardboard template. With its help, marks are easily and effortlessly made for all fixtures and the chimney. When the place for the boiler is finally selected, the template should be attached to the wall. It should have the points of the lines of the fasteners and the places where the wires will be connected. These important marks should be transferred to the wall with a marker or colored pencil. The template can then be removed.

The next step is to drill holes for the dowels. To do this, select a drill with the desired diameter. Each dowel must be matched to the material and wall thickness. After the holes are ready, metal corners are attached to the wall.

Then you need to remove the top cover of the unit. Now you can safely hook the equipment to the hanging corners on the wall. Before installing the brackets, you need to make sure that all the chimney fittings are of the correct dimensions exactly according to the instructions, otherwise there will be problems later. The bracket to which the gas boiler is attached must itself be very securely fixed to the wall. This is the most important point.

It is important to remember that depending on the type of wall, there are different ways of fixing. There are different types of fastening installations, each of which is designed to install a certain type of unit and type of load.

During installation, it is important to ensure that no debris gets inside the fan. The branch pipe through which the combustion products will be removed must recede from the wall surface by at least two centimeters.

Boiler installation tools

Before installing the wall-mounted unit, you should acquire in advance:

  • screwdrivers
  • fasteners,
  • glue,
  • tow,
  • wrenches
  • drill,
  • gloves,
  • threaded sleeve,
  • non-combustible finishing material.

First you need to close the water supply using a valve. After that, the boiler and the pipeline can be connected using a threaded sleeve. To achieve the most dense fixation, it is imperative to use tow. The unit must be connected first from the front side. The hot water supply is connected to the upper pipe of the unit, and the return is connected to the lower one.

The junction box of the unit must be connected to the power supply cable, and a safety contact must be tapped from the switch.

Thanks to the cable, power is supplied to a powerful boiler, and therefore each fuse should not exceed three amperes in power, or the fuse should have a rating less than the current rating required for high-quality use of the boiler. At the end of this type of work, you need to connect the gas equipment to a reliable ground.

As you can see, installing a gas boiler on your own is quite feasible in the shortest possible time without wasting time, effort and money. Do-it-yourself installation of a wall-mounted gas boiler in the video can be studied in more detail. For example, the most frequent questions were related to the installation of the Danko gas boiler, which is gaining popularity.

The cost of installing a gas boiler is much lower than the cost of calling a specialist. In addition, the work is carried out quickly, and the skills gained during the installation will be useful in the future.

You have purchased a new gas boiler for a private house and it's time to take its place in the furnace. To do this, you can hire a specialized company or contact the appropriate service. But the cost of installation in this case will significantly hit the wallet, while there is an opportunity to reduce the cost of the process. Yes, some operations are only allowed to be performed by licensed organizations, but this is only half of the work, the rest can be handled independently. Here we will tell you about how to install a gas boiler in a private house from start to finish.

Where to begin?

Since the installation of new gas-using equipment requires compliance with certain rules, it is worth ordering all work requiring a license to the gas service:

  • Issuance of technical specifications.
  • Development of design documentation.
  • Work on connection to the natural gas main.

You can do the rest of the actions yourself. First, you need to obtain from the gas service the technical conditions for the installation of gas equipment. Check them out or make a copy and immediately order project documentation from them. When it is ready, it will need to be approved by the gas service. As you might guess, this procedure is a pure formality, after its completion a team will come to your home and install the gas boiler in terms of its connection to the fuel line, about which an appropriate act will be drawn up.

All that remains for you to do is to complete the piping and connection to the heating system, laying the electrical networks. Here it will be possible to save money, either by doing everything with your own hands, or with the help of familiar plumbers. The last stage is the final paperwork.

This is just a brief description of one of the possible algorithms for solving the problem, but in fact, not everything is so simple, because gas boilers must be installed in compliance with regulatory requirements, it will not hurt to get acquainted with them even at the stage of choosing a heat generator.

Boiler installation requirements

First of all, it is necessary to take into account all the requirements for the room where the heat source is supposed to be placed. The options are:

  • kitchen;
  • a room inside the house, adjacent to one of the outer walls and having windows;
  • premises in the basement or basement;
  • in the outer annex.

In the kitchen, installation standards allow you to place a floor-standing or wall-mounted unit with a heating capacity of up to 60 kW. Equipment with indicators from 60 to 150 kW can be installed in a separate room on any floor, and from 150 to 350 kW - only on the first or basement floor, in the basement or annex. At the same time, it is important to comply with the dimensions of a separate room or an attached part, they cannot be less than prescribed in the standards. The minimum standard height of such a room is 2.5 m for any power within the specified limits.

Note. The heat power values ​​prescribed in the standards and affecting the conditions for installing the boiler are the total power of all units in the boiler room, including those working for the needs of hot water supply.

For heat generators with a capacity of up to 150 kW, in accordance with the standards, the smallest volume of the room for installing a gas boiler is 15 m3, in addition, for each kW of hot water equipment, 0.2 m3 is added to this volume. If the total indicator of all units exceeds 150 kW, then the dimensions of the room are not standardized. But the rules for the installation and safe operation of boilers apply, according to which it is necessary to maintain technological gaps between the units and the walls of the room, they are taken for reasons of ease of maintenance and access to all systems in the boiler room. The dimensions of the passages in accordance with the rules are as follows:

  • From the protruding part of the gas burner device to the wall on the front side of the heat generator - at least 1 m.
  • If the operating instructions for the unit say that it needs to be serviced from the side or behind, then you will have to maintain a passage width of 1.5 m, when there is no such record, but you need to provide access to other equipment or fittings, then it is enough to make a clearance of 700 mm. In other cases, the installation requirements are put forward in the documents for the product from the manufacturer.
  • If it is planned to install 2 heat sources in the furnace, then you should not place them opposite each other, since you will have to provide a gap between the protruding parts of the burners of at least 2 m.
  • Nothing can be laid through the passages at a height lower than 2 m.

For a kitchen where it is allowed to place not too powerful heating equipment (up to 60 kW), not the most stringent requirements are imposed on the installation of gas boilers. You just need to comply with the volume standard given above, and also provide air exchange in the amount of 3 times in 1 hour. Additionally, it is required to supply fresh air for fuel combustion, its consumption for each unit is indicated in the technical specifications. This standard is valid for all types of boiler houses.

Note. For heat generators with a closed chamber, the installation standards for gas boilers are not forced to provide an air mixture for combustion, since they take air directly from the street through a coaxial chimney, which will be discussed below.

In the regulatory documents, it is proposed to organize ventilation for the boiler in the kitchen using an exhaust shaft and a supply grille built into the front door. The cross-section of this lattice is also standardized, its area cannot be less than 0.025 m2. In the same way, it is possible to arrange air exchange in separate furnaces. Difficulties with the supply of fresh air can arise in the basement or basement floors, it is possible that a special supply fan will need to be installed to meet the technical conditions.

In boiler rooms located on the first, basement floor or in an annex, window openings with a glazing area of ​​at least 0.03 m2 are needed for each cubic meter of room volume. Requirements for fire resistance of walls, separate foundations and entrance doors are also put forward for the attached premises. In addition, the extension cannot be built on the front facade of the building, and during construction it is necessary to retreat from the nearest window or door 1 m horizontally.

It should be noted that the requirements for a gas boiler located in a wooden house are identical to the standards for buildings made of other materials, that is, the rules for installing boiler rooms are the same for all buildings.

Boiler installation work

When a suitable room has been selected and the project documentation has been completed for it, you can proceed with your own installation of the heat generator in place. To do this, you will need a gas boiler connection diagram in a private house, which must be present in the project. It shows the installation site, the distance to all enclosing structures and the technical requirements for the production of work.

Often, the installation of floor-standing gas boilers requires a foundation. In many cases, it is not needed, for example, when a high-quality screed is arranged in the room, and the weight of the unit does not exceed 50 kg. If the weight of the equipment is more than this value, then you will have to prepare the base. To do this, it is necessary to destroy the existing screed, pour a crushed stone pillow and carefully tamp it. Then tie a mesh made of periodic profile reinforcement with a diameter of 8 to 12 mm, lay it on the finished base and pour concrete.

In order to withstand the technology of installing gas boilers, the dimensions of the foundation in the plan should exceed the dimensions of the equipment by 50 mm, and in height it is made protruding 50-100 mm above the level of the screed. Complete hardening of a concrete slab will take you at least 2 weeks, this must be taken into account when planning work.

Further, a fireproof gasket made of asbestos or metal is placed on top of the foundation and a heat generator is placed on it, adjusting the legs of the unit in such a way as to maintain a clear horizontal. After that, using the gas boiler installation scheme, it is connected to all engineering networks, except for the fuel line. This connection, as mentioned above, is carried out by a licensed organization.

To install a wall-mounted gas boiler in a private house, you need not a foundation, but a solid foundation in the form of an outer wall, which is able to withstand the weight of the unit. First of all, markings are made on it, showing where the heat generator itself will be suspended and where the chimney will come out. Then, using a punch, a through hole is drilled in this place, into which a metal sleeve is inserted.

There is no particular difficulty in hanging a wall-mounted gas boiler. If the action takes place in the kitchen in an apartment or house, it is necessary to take measures to protect the furniture from debris and then proceed with the fastening process. Difficulties can arise during the installation of heavy units, whose power reaches 120 kW, here you cannot do without an assistant.

Note. When the wall-mounted boiler is attached to a wall made of combustible material, a special bracket must be made to make a 45 mm gap between the wall surface and the rear panel of the heater. Also, a sheet of non-combustible material should be attached to the wall, which plays the role of a protective screen.

The last step is the piping of the gas boiler and the chimney device. Here it is necessary to compactly place taps and other fittings under the body of the heat generator so that everything looks neat and at the same time it is possible to disassemble or change any element. Therefore, when the heating circuit in the house is made of polypropylene pipes, it is better to use bronze taps and a sump, and connect plastic pipes through threaded adapters. In this regard, the installation of a double-circuit gas boiler is somewhat more complicated, where it will be necessary to lay pipes for hot water supply and correctly connect them to the corresponding nozzles.

Chimney requirements

In essence, the requirements for chimneys of floor and wall gas boilers are identical, the difference may be in the design of the flue itself. It depends on the device of the heat source:

  • Heat generators with an open combustion chamber take air from the room and discharge the combustion products through a traditional natural draft chimney.
  • Units equipped with a closed chamber draw in air from the street forcibly, with the help of a fan, through a double-walled pipe, which simultaneously serves as a gas duct (coaxial chimney).

A traditional chimney for a gas boiler is installed in the thickness of the wall or suspended from the outside of the building. The cross-section of the outlet from the unit determines the diameter of the entire chimney, it should be the same size, or better - 20-50 mm larger. The horizontal section connecting the boiler to the chimney is ideally 1 m long, the maximum permissible length is 2 m.

Below the insertion point, a door is required for cleaning and internal inspection, and the blind end of the vertical pipe is equipped with a condensate drain system. When installing the chimney of a gas boiler, it must be remembered that it is not allowed to cover the outlet of the pipe with umbrellas, deflectors, weather vane and so on. Only the restriction nozzle can be supplied in accordance with the regulations.

In contrast to traditional flue gas exhaust ducts, it is much easier to install a double-walled chimney for heat generators with a closed chamber. Having made a hole of the required diameter in the outer wall and built a metal sleeve into it, a coaxial chimney is installed, which is a horizontal double-walled pipe of a certain length. The only condition that must be met is a slight bias towards the smoke outlet. It is done so that the condensate formed in the air duct does not flow into the boiler.

Conclusion

So, doing the installation and piping of the boiler with your own hands is a difficult task, but quite feasible. It will take a lot of time and patience to complete all the documentation, but the installation work itself will take a maximum of 3-4 days, or even less. It is important to prepare well and purchase in advance all the missing elements of the strapping scheme, as well as fasteners.

This is not an easy task. The boiler cannot be hung up somehow, since the safety of people living in the house often depends on how correctly the wall-mounted boiler is installed.
This is due to the fact that the installation of this device is carried out in strict accordance with the technical requirements and standards adopted in Russia at the legislative level.

That is why installing a wall-mounted boiler with your own hands is an extremely time-consuming and difficult process for a beginner.

Stages of preparation for boiler installation

Before the owner of the house starts, you will need to collect some documents:

  • gas supply agreement for the house;
  • terms of reference and installation diagram of the gas system, approved by the relevant authorities;
  • written permission from the gas inspector for the installation of equipment.

Boiler installation rules and regulations

Gas heating equipment is installed in accordance with the developed and approved technologies that ensure the safety of its operation.

  1. The question of how to install a wall-mounted boiler begins with preparing a room for it. The room must meet certain requirements: the boiler room can be located anywhere in the house, except for the bathroom, living rooms and a toilet. However, when installing wall units, this requirement can be relaxed depending on the type of boiler. The volume of the room is from four square meters, the height of the ceiling is from two meters. The width of the doorway is at least 800 mm. Also, the room should be provided with natural lighting of the boiler through the window. At the same time, the size of the window must correspond to 0.3 sq. for every 10 sq. premises.
  2. The rules for installing a wall-mounted gas boiler regulate the supply of a certain amount of fresh air with the help of forced ventilation to the place of use of the boiler. An insufficient amount of incoming air may be associated with the accumulation of a substance hazardous to health and life in the room.
  3. : the standards for its placement are such that the distance from the wall to the surface of the boiler must be more than 10 cm. If this distance is less than the prescribed one, the wall must be protected with a fire-resistant coating.
  4. Gas pipes can be metal, but not plastic.
  5. The chimney opening must correspond to the boiler output. Moreover, its height should be at least 5 m, provided that the chimney is installed above the ridge on the roof of the house. When installing a chimney, it can have no more than three bends.
  6. When organizing the power supply system, it is necessary to provide for the presence of an automatic machine with current protection and thermal protection.
  7. In the room where the boiler will stand, there should be a gas sensor linked to the relay. In the event of a gas leak, the sensor must send a relay signal to block the gas supply. In addition, an audible alarm should sound.
  8. Installation of a wall-mounted gas boiler, the standards for starting it oblige to provide the device with a gas meter.
  9. If there are other gas appliances next to the boiler, then the distance between the appliances is set at at least 20 centimeters.
  10. During installation, the requirements even affect the subject of the complete completeness of the equipment. The complete set of the boiler must comply with the standards and contain: manual, fasteners, a template made of paper for installation, special keys and fasteners.
  11. The installation height of the wall-mounted boiler is 80 cm - 160 cm from the floor surface.

If all these requirements are met, then there is no doubt about the reliability and fire safety of the gas heating system. It should be borne in mind that the heating system should be regularly maintained by the employees of the city gas service.


A simple piping of a wall-mounted double-circuit gas boiler, the photo of which you see on this page, can be done by your master, or you can ...


  • In order not to spend money on a full-fledged chimney, you will need a coaxial pipe for a wall-mounted gas boiler. The installation, the photo of which is published on this ...
  • When installing a heating system, sooner or later you get to the installation of a boiler room. Very often in Russia and the CIS countries, they install wall-mounted gas boilers in private houses and not only. This is due primarily to the good gasification and ease of use of such boilers in comparison with solid fuel ones.

    Ideally, a certified specialist should be involved when installing a wall-mounted gas boiler. But what if there was a problem with such frames? Let's understand this issue in detail.

    Many companies engaged in the production of gas equipment offer users various types of heating boilers, the designs of which are provided exclusively for working with blue fuel. They can be used for absolutely any scale and area.

    Speaking about the types of installation, boilers are divided into:

    Floor

    They are characterized by such indicators as high power, durability and reliability. Their purpose is to be installed in structures with an area above the average measure and area. However, the flagship models also have their drawbacks: the need for a separately installed and equipped room.

    Wall mounted

    Boilers of this type are a great variation for small private houses. Therefore, they do not need to build a separate room, and they are multifunctional models. They contain a built-in expansion tank, a circulation pump, a security group, sophisticated automation. Assembly and installation do not require special increased conditions.

    This type of boilers is installed everywhere and is widely used in modern apartments, summer cottages, houses and cottages, which occurs due to the provision of maximum comfortable environmental conditions and minimum efforts and costs for assembly and installation. At the moment they are created using design solutions and compact resolutions. We have also written these types of boilers.

    There is also a division according to the type of boiler combustion chambers.

    Open combustion chamber

    This model is prone to natural traction. One way or another, air is produced and enters from the inside of the room, and the combustion products themselves are removed exclusively through the chimney. If there is not enough ventilation, there will be a lack of oxygen. The performance of heating units with an open combustion chamber depends on the draft. It is important to install the chimneys correctly and not save on their insulation. At the same time, there is a high probability of the risk of combustion products entering the interior of the room. Based on this, the price categories are much below average.

    Closed chamber

    They are characterized by forced draft. Electric fans (smoke exhausters) are installed in them, with the help of which it becomes possible to remove substances formed during combustion by the chimney. Air enters the chamber by sucking it in through the outer, outer pipe, and the outlet through the inner one.

    Difference between indoor and outdoor cameras

    The answer is quite simple and clear: in their features of the device, in the way they absorb oxygen.

    It should be understood that in a residential building you need to resort to such an option as a closed one, since only it will be acceptable for use in private buildings. For open ones, a separate room is required

    Studying the process diagram, it can be noted that the air, which ensures normal and stable functioning, is absorbed through the coaxial chimney from the external space. In the future, already processed substances also get from the premises to the street. So there is no need for extra costs and expenses for additional ventilation devices.

    It is worth resorting to buying an open version only for their installation in boiler rooms. Its principle of operation is the absorption of oxygen from the oxygen contained in the room. Therefore, it is important that regular and stable ventilation of the building is ensured.

    The main rule is to install a gas boiler completely separate from the house, which ensures safety, since the likelihood of gas leakage and substances formed during combustion is reduced to a minimum, which is caused by the non-use of air from the house. To completely exclude the possibility of emergency emergencies, it is worthwhile to first pass a thorough check of the pipeline for the presence of various kinds of distortions, scratches and damage.

    Look at an example of converting a boiler room from an open boiler to a closed one:

    The advantage of installing a boiler with a closed chamber

    1. When getting rid of the products consumed in the isothermal process, a reverse reaction occurs - cooling, which dramatically increases the safety and reliability of such boilers.
    2. The room equipped for this device does not overheat and is protected from various and numerous air pollution, since combustion occurs only on the street, that is, not within the house.
    3. High efficiency
    4. Air enters the room, the pressure rises, as a result of which its temperature rises. Thus, the closed chamber is environmentally friendly and clean.

    There are also disadvantages:

    An installed gas boiler with a closed chamber will not be able to work without the availability of electricity. But as soon as electricity appears, all work starts automatically.

    Requirements for a boiler room with a gas boiler

    Much depends on the boiler performance: if it reaches more than 30 kilowatts, then there is a need for a separate room. It is on the basis of the provisions of the ‘Building norms and rules’ that specific orders are being built and created for the arrangement of a boiler room specialized in heating by combustion of products.

    • perhaps in attics, basements, that is, in special rooms of houses. But it is worth considering that an empty corridor is required, sufficient illumination.
    • The established volume of at least 14 square meters, taking into account a capacity of 30-60 kilowatts and above 15 square meters, is intended for boilers of higher productivity.
    • Comfortable and unhindered access to the device.
    • Wall covering with non-combustible material.
    • Providing a ventilation process in three times the amount of air exchange.

    Three options for installing a gas boiler

    When installing a wall-mounted gas boiler in a private house, you have three ways:

    1. You yourself contact the company and order the service of installing a gas boiler at home. The company's employees not only install the boiler, but also provide post-warranty service, and also put the boiler for service.
    2. In the event that you are unable to order the boiler service and its installation directly from the company, a specialist is ordered to install the boiler. Then the company that sold you the boiler sends the service itself. She carries out commissioning, as well as puts the equipment for service.
    3. If you live in a rural area, and there are no service centers nearby, then you can do the installation yourself, following the instructions. Moreover, the instructions for installing a wall-mounted gas boiler in a private house should be exclusively from the manufacturer. It is also necessary to consider when installing your heating system.

    Do-it-yourself gas boiler installation

    In short, the installation of a gas boiler in a private house is possible for everyone. Follow the installation diagram, installation rules and everything will work properly. But the exception is precisely the input, which must be carried out by specialists of the gas service. Likewise, testing of the boiler is carried out only by a specialized company, since they have certificates and licenses for this.

    However, it will be safer to rely on the qualified employees of a professional company. After all, only they will be able to carry out the necessary work with excellent accuracy and literacy and provide the necessary safety during the operation of the equipment.

    Gas boiler installation steps

    Chimney hole

    Before installing the pipe under the chimney, it is imperative to create a hole with the exact size (usually 120 mm) and place a specific protective and sealing apron, to which the chimney is connected.

    Boiler installation

    The complete set of the boiler usually includes, first of all, the boiler itself and the operating instructions, a warranty card, a fastening bar, an installation diagram.

    First of all, you need to decide on the place of installation of the boiler. In European countries, boilers are usually installed in the kitchen. They do not violate harmony and fit into almost every kitchen interior. The equipment works quietly.

    You can mount a wall-mounted gas boiler in a basement or basement room. In this case, certain standards must be observed. The boiler is installed by at least two people, even if it is not too heavy. There must be a distance of at least 30 cm on all sides of the boiler. Regarding the height of the boiler: it is important that the control panel is positioned according to the owner's height.

    Important! To keep the control panel out of the reach of children. You should not place the boiler knowingly high above the floor, because in case of repair or service work, it will be inconvenient for specialists, you will have to use a step-ladder or stool.

    Next, we take a mounting template (it is attached to the boiler), which is being developed for several types of boilers. Using the template, you can mark the outlets of pipes, chimneys and fixtures and then install a wall-mounted gas boiler without any problems. In Europe, in the process of building a house, pipes are laid in accordance with a pre-selected gas boiler.

    Chimney installation

    The coaxial chimney has a diameter of about 100 mm, but the hole is made with a diameter of 120 mm or more. The backlash is necessary so that the chimney is directed towards the street at an angle of approximately 5 degrees. Condensation that forms during operation must be discharged into the street. After installing the chimney, the hole can be foamed with polyurethane foam. The coaxial pipe consists of two pipes. A pipe with a diameter of 60 mm removes combustion products, and air from the atmosphere is sucked into the space between 60 and 100 mm. This is why the pipe walls are slightly warm.

    The fixing bolts have plastic dowels. They can be used for a variety of walls.

    Connecting pipes to the boiler

    For piping hot and cold water supply, as well as heating systems, two options are possible. The first is that the pipes are brought in during the construction or repair phase, taking into account the boiler you have chosen. However, it may be necessary to install a wall-mounted gas boiler in the event that a heating system already exists.

    The supply pipeline is connected to the boiler supply, opposite to the return. When installing a double-circuit boiler, a cold water supply circuit must be connected to the boiler. Lead the hot pipeline to the remaining connection and mount it in the hot water supply riser.

    Do not forget to install a dirt filter on the return line, a check valve on the supply, as well as ball valves for each connection.

    A dirt filter is necessary to prevent coarse debris from entering the boiler. A check valve is needed to protect against sudden squeezing of the coolant into the supply. The taps will be useful when servicing the boiler.

    As you understand, there is nothing complicated in installing a wall-mounted gas boiler and you can do the installation yourself.

    Gas connection

    This action can only be performed by an employee of the gas service. He will bring you a pipe according to the project, and the gas hose from the pipe to the boiler is assembled independently.

    It is advisable to use cardboard spacers. The rubber pads can break when clamped, which is very unsafe. Today, paronite cardboard gaskets are in high demand.

    Electrical installation

    It is produced for boilers with modern automation and for models with a closed combustion chamber, since they are equipped with electronic devices. Usually it is limited to supplying electricity closer to the boiler and installing a plug to the boiler wire. Do not forget about phase dependence. If suddenly the boiler does not turn on, just try turning the plug and plugging it in again.

    Sockets and other connections must be located at a distance from the boiler so that in the event of an abnormal situation, splashes do not fall on the electrical wiring. The gas hose must be covered with a yellow metal braid. It is necessary so that there is no breakdown of the hose in the event of a lightning strike or in case of overvoltage.

    In order to ensure the safe operation of the gas boiler, it is better to install a mains voltage stabilizer.

    Starting a gas boiler

    After the wall-mounted gas boiler is mounted, it must be filled with coolant. If the system is new, the pressure should be approximately 1.8 bar. When starting for the first time, set the temperature to 45-50 degrees. Modern boilers quickly accelerate the system. Try to increase the temperature gradually to avoid thermal shock. If the boiler capacity is 24 kilowatts, then this is enough to heat a house of 300 sq. meters in case the house is well insulated. Try not to buy boilers of lower power, since even if the area of ​​the house is about 160 sq. meters, but it is poorly insulated, then even 24 kilowatts may not be enough. It should also be taken into account that the gas has a different calorific value.

    Installation cost

    When contacting specialists in the installation of gas boilers, many customers are interested in the cost of the work. It is important to understand that in different regions the pricing policy may differ.

    Complex connection of a boiler with a hole and with start-up starts from 5000 rubles. This amount will be requested from you, provided that there will be no additional work. If the heating system is made of metal pipes, then the cost of installing wall-mounted gas boilers will be higher. In the region of 6000-8000 rubles.

    Also, lay down 3000-4000 rubles for the purchase of materials (hose, pipes, taps, fittings, etc.)

    The gas boiler can only be installed by competent people who have permission to do this type of work. Even if the boiler is installed by the company's specialists, you need to know the system of its operation. The boiler itself is as safe as possible in operation as it has many degrees of protection.
