Installation of a wall-mounted gas boiler: do-it-yourself installation in compliance with the norms. How to install a wall-mounted gas double-circuit turbocharged boiler "Beretta

The task is not easy. The boiler cannot be hung up somehow, since the safety of the 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 the installation of the boiler

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

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

Boiler installation rules and regulations

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

1. The question of how to install a wall-mounted boiler begins with the preparation of 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 bathroom. However, when installing wall units, this requirement can be relaxed depending on the type of boiler. The volume of the room - from four square meters, ceiling height - from two meters. Width of a doorway - not less than 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 should correspond to 0.3 sq.m. for every 10 sq.m. premises.
2. Wall installation rules gas boiler regulate the flow of a certain volume fresh air with the help of supply ventilation to the place of use of the boiler. An insufficient amount of incoming air may be due to the accumulation of a substance hazardous to health and life in the room.
3. : the standards for its placement are such that there should be more than 10 cm from the wall to the surface of the boiler. 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 capacity of the boiler. At the same time, its height must 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 a power supply system, it is necessary to provide for the presence of an automatic machine with current protection and with thermal protection.
7. In the room where the boiler will stand, a gas sensor linked to a relay must be placed. In the event of a gas leak, the sensor must signal the relay to block the gas flow. In addition, an audible alarm should sound.
8. Installation of a wall-mounted gas boiler, when starting it, the regulations oblige to provide the device with a gas meter.
9. If there are others near the boiler gas appliances, then the distance between the devices is set at a mark of at least 20 centimeters.
10. When installing, the requirements even affect the subject of a complete set of equipment. The complete set of the boiler must comply with the regulations and contain: a manual, fasteners, a paper template 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 must be regularly Maintenance by employees of the city gas service.

In order not to spend money on a full-fledged chimney, you will need a coaxial pipe for a gas wall-mounted 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 homes and not only. This is primarily due to good gasification and ease of use of such boilers in comparison with solid fuel ones.

Ideally, when installing a wall-mounted gas boiler, you need to involve a certified specialist. But what if there is a problem with such frames? Let's look into this issue in detail.

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

1. You yourself apply to the company and order the service of installing a gas boiler at home. Employees of the company not only install the boiler, but also provide post-warranty service, as well as put the boiler for service.
2. In the event that you are not able to order service maintenance of the boiler and its installation directly in the company, a specialist is ordered to install the boiler. Then the company that sold you the boiler itself sends a specialist. He carries out commissioning, and also puts the equipment for service.
3. If you live in countryside, and there are no service centers nearby, then you can install the equipment on your own 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.

Gas boiler installation options

The complete set of the boiler usually includes, first of all, the boiler itself and the instruction manual, a warranty card, a mounting bracket, and an installation diagram.

First of all, you need to decide on the installation location of the boiler. IN European countries boilers are usually installed in the kitchen. They do not disturb the harmony and fit into almost every kitchen interior. The equipment is quiet.

You can mount a wall-mounted gas boiler in the basement or basement. In this case, certain rules must be observed. The boiler is mounted by at least two people, even if it is not too heavy. A distance of at least 30 cm from the boiler must be provided on all sides. Concerning the height of the boiler: it is important that the control panel is located depending on the height of the owner.

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

Next, we take a mounting template (it is attached to the boiler), which is developed for several types of boilers. Using the template, you can make marks for the outlets of the pipes, chimney and fixtures and then install the 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 play is necessary so that the chimney is directed towards the street at an angle of approximately 5 degrees. Condensate that forms during operation must be drained to the street. Then, after installing the chimney, it can be foamed with mounting foam. The coaxial pipe consists of two pipes. A pipe with a diameter of 60 mm removes the products of combustion, and air from the atmosphere is sucked into the space between 60 and 100 mm. That is why the walls of the pipe are slightly warm.

Mounting bolts have plastic dowels. They can be used for various walls.

There are two options for connecting pipes for hot and cold water supply, as well as for the heating system. The first is that the pipes are brought in at the stage of construction or repair, taking into account the boiler you have chosen. However, it may be necessary to install a wall-mounted gas boiler if a heating system already exists. For example, the Leningradka system with top filling. The boiler crashes taking into account the existing wiring. The boiler must be connected to pipes of large diameter. The system will work well because it is gravity-fed and has a large volume of coolant. Can be used polypropylene pipes even 40 mm in diameter.

Gas connection to the boiler

It is usually connected with an oxygen hose, which has a diameter of 8 mm, while a 20 mm hose must be used. Green gaskets are used for heating and water supply, as for gas gaskets, they are blue. It is advisable to use cardboard spacers. Rubber gaskets when clamped, they can tear, which is very unsafe. Today, paronite cardboard gaskets are in high demand.

Sockets and other connections must be located at a distance from the boiler so that, in case of an emergency, splashes do not fall on the electrical wiring. The gas hose must be in 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 safety of operation of a gas boiler, it is better to install a voltage regulator.

Starting a gas boiler

After the wall-mounted gas boiler is mounted, it must be filled with coolant. If the system is new, then the pressure should be approximately 1.8 bar. At the first start, you should not, as they say, gas, set the temperature at 45-50 degrees. Modern boilers quickly accelerate the system. Try to increase the temperature gradually to avoid thermal shock. If the boiler power is 24 kilowatts, then this is enough to heat a house of 300 square meters. meters. This is the case if the house is well insulated. Try not to buy boilers of lower capacity, because even if the area of ​​​​the house is approximately 160 square meters. meters, but it is poorly insulated, then even 24 kilowatts may not be enough. It should also be noted that gas has a different calorie content.

Only competent people who have access to this type of work can install a gas boiler, speaking in principle, it is not difficult. Even if the boiler is installed by the company's specialists, it is necessary to know the system of its operation. The boiler itself is as safe as possible in operation, as it has many degrees of protection.

About offline gas heating with hot water, if not dreaming, then surely any householder was seriously thinking, both in a city apartment and in a private house. Only today it is able to reliably provide comfortable temperature in the house is cheaper than the central one. However, installing a gas boiler with your own hands is a complex, responsible matter that requires a permit. Actually, it only makes sense to take it on yourself only if you have sufficient funds to purchase a double-circuit boiler with a boiler and a complete set of automation, and your housing is suitable for installing a boiler according to specifications.

The second case when a gas boiler is needed is if you are not rich, but hot water in the house is not at all and is not expected. In this case, you need the simplest budgetary single-circuit flow-through boiler for hot water supply, which allows you to wash the dishes and take a shower. A gas boiler is more expensive than an electric boiler, but, given the cost of installing a gas meter, at current rates it pays off in a winter of a year and a half, depending on the place of residence. If, again, you can put it in your apartment, and you are not afraid of walking through the authorities.

Two big differences

The boilers mentioned above are the extremes of a huge variety of models of gas water heating devices. They are available for self installation. Any other gas heating boiler for installation requires professional work. However, every cloud has a silver lining - specialized firms take upon themselves the preparation of the premises with the paperwork. But why can only the "tips of scissors" be installed by yourself?

Simple water heater

The simplest boiler is really very simple: gas-burner, heat exchanger - that's all. It is enough to connect water, gas to it, bring the exhaust into the chimney - and you can use it. If the papers are already issued; otherwise, an inevitable large fine.

Home boiler room

A double-circuit boiler with a boiler and full automation is so “smart” that it is as easy to install as the simplest one. Automation is important not only for simplicity: complete system with a double thermostat and a microprocessor monitors the temperature in the house and on the street, according to a given program, reduces heating to a minimum according to sanitary standard when no one is at home (for example, when everyone is at work). The gas consumption of such a boiler is 30-70% less than with manual or semi-automatic adjustment, and the more severe the weather, the more savings.

But such a home boiler room has a serious drawback: if you find yourself in a natural disaster area and the power supply is interrupted, the automation “stalls”, and the boiler goes into the minimum space heating mode. Therefore, such a boiler requires an additional expense for a guaranteed power supply. It is not difficult to provide it yourself, see below.

Where it is possible and where it is impossible to put a gas boiler

The rules for installing a gas boiler provide the following requirements for the installation of a HEATING boiler, regardless of whether it also provides domestic hot water or not:

1. The boiler must be installed in a separate room - a furnace (boiler room) with an area of ​​​​at least 4 square meters. m., with a ceiling height of at least 2.5 m. The rules also state that the volume of the room must be at least 8 cubic meters. Based on this, you can find indications of the admissibility of a ceiling of 2 m. This is not true. 8 cubes is the minimum free volume.
2. The furnace must have an opening window, and the width of the door (not the doorway) must be at least 0.8 m.
3. Finishing the furnace with combustible materials, the presence of a false ceiling or raised floor in it is unacceptable.
4. Air must be supplied to the furnace through a through, non-closable vent with a cross section of at least 8 sq.cm. per 1 kW of boiler power.

Note: 8 cubes free - with a boiler power of up to 30 kW. For power from 31 to 60 kW - 13.5 cubic meters; for power from 61 to 200 kW 15 cubic meters. For boilers with a closed combustion chamber, the volume of the furnace is not standardized, but the dimensions must still be observed.

For any boilers, including wall-mounted hot water boilers, the following general standards must also be met:

• The boiler exhaust must exit into a separate flue (often incorrectly referred to as a chimney); use for this ventilation ducts unacceptable - life-threatening combustion products can get into neighbors or other rooms.
• The length of the horizontal part of the flue must not exceed 3 m within the furnace and have no more than 3 angles of rotation.
• The outlet of the gas duct must be vertical and raised above the ridge of the roof or the highest point of the gable on flat roof not less than 1 m.
• Since the products of combustion form chemically aggressive substances during cooling, the chimney must be made of heat- and chemical-resistant solid materials. The use of layered materials, e.g. asbestos-cement pipes, permissible at a distance of at least 5 m from the edge of the boiler exhaust pipe.

When installing a wall-mounted hot water gas boiler in the kitchen, additional conditions must be met:

• The height of the boiler suspension along the edge of the lowest branch pipe is not lower than the top of the sink spout, but not less than 800 mm from the floor.
• The space under the boiler must be free.
• A strong fireproof metal sheet 1x1 m should be laid on the floor under the boiler. Gas workers and firefighters do not recognize the strength of asbestos cement - it wears out, and the SES prohibits having anything containing asbestos in the house.
• The room should not have cavities in which combustion products or an explosive gas mixture can accumulate.

If the boiler is used for heating, then the gas workers (who, by the way, are not very friendly with the heating network - it always owes them for gas) will also check the condition of the heating system in the apartment / house:

• The slope of the horizontal pipe sections must be positive, but not more than 5 mm per running meter by the flow of water.
• At the highest point of the system must be installed expansion tank and air faucet. It is useless to convince you that you will buy a “cool” boiler in which everything is provided for: rules are rules.
• The condition of the heating system must allow it to be pressure tested at a pressure of 1.8 atm.

The requirements, as we see, are tough, but justified - gas is gas. Therefore, it is better not to think about a gas boiler, even a hot water boiler, if:

• Do you live in a block Khrushchev or other apartment building without a main gas duct.
• If you have a false ceiling in your kitchen, which you do not want to clean, or a capital mezzanine. On a mezzanine with a bottom made of wood or fiberboard, which, in principle, can be removed, and then there will be no mezzanine, gas workers look through their fingers.
• If your apartment is not privatized, you can only rely on a hot water boiler: allocating a room for a furnace means redevelopment that only the owner can do.

In all other cases, you can put a hot water boiler in the apartment; heating wall is possible, and floor - very problematic.

In a private house, any boiler can be installed: the rules do not require that the furnace be located directly in the house. If you make an extension to the house from the outside under the furnace, then the authorities will only have fewer reasons for nit-picking. In it, you can put a floor gas boiler of high power for heating not only the mansion, but also office space.

For private housing of the middle class optimal solution- wall-mounted boiler; under it is not required, as for the floor, to arrange a brick or concrete pallet with sides of half a meter. Installing a wall-mounted gas boiler in a private house also does without technical and organizational difficulties: a fireproof closet for a furnace can always be shielded, at least in the attic.

Power supply

The automation of heating boilers consumes little electricity, but according to the rules, the boiler still needs a separate wiring branch with a 20 A automatic machine, like for a boiler. For backup power, any computer UPS is well suited. Kilowatt will "hold" the automation for half a day or a day. This is quite enough to take the necessary measures in case of emergency.

About the flue

The cross-sectional area of ​​​​the house flue for it depends on the required power of the boiler (see below). At any power, the diameter of the flue must be at least 110 mm and not less than the diameter of the exhaust pipe. The dependence of the diameter of the flue on the power of the boiler is as follows:

• up to 24 kW - 120 mm.
• 30 kW - 130 mm.
• 40 kW - 170 mm.
• 60 kW - 190 mm
• 80 kW - 220 mm.
• 100 kW - 230 mm.

Boiler selection

Power

The fact that the power of the boiler must be sufficient is obvious. But it should not be excessive, especially if the heat exchanger is cast iron. Hot cast iron cracks from drops of condensate from the flue. There is another dangerous effect: the dew point temperature of the exhaust gases is approximately 56 degrees Celsius. If the heating return water temperature is lower, acidic condensate may form in the combustion chamber. What does this have to do with excess power? Too powerful a boiler will quickly warm up the system and go into standby mode before it cools down. The thermal inertia of a powerful heat exchanger is great, and while it warms up again, acid dew can fall out.

With a properly selected boiler power, the temperature in the combustion chamber will be 80-90 degrees. The allowable difference in power is quite large, but if you put a 60 kW boiler in a medium-sized private house, then acid rain from the inside will quickly disable it.

The required boiler power for a particular room is determined thermotechnical calculation. It is easier for residents of high-rise buildings: the data is available in the DEZ, the technical inventory bureau or the owner. In any case, you can use the approximate data by calculating an intermediate value for yourself. Maximum power values ​​are given for cases of minimum outdoor temperature at -25/-40 degrees:

1. One-room apartment on the middle floors - 8/14 kW.
2. Corner apartment 60 sq.m. total area on the top floor of the block Khrushchev - 20/28 kW.
3. Private house 100 sq.m common - 24/38 kW.

Boiler

The purpose of the boiler is the accumulation of hot water for domestic needs. If you look at the instructions for the boiler, then the power there will be indicated through a fraction, for example - 10/22 kW. The first digit is the heating output for average conditions; it determines the gas consumption by 80%. Second power, maximum - for rapid heating household water.

If the boiler is empty, the boiler stops heating the heating for a while (it does not have time to cool down) and heats up to the maximum domestic water. The gas consumption is, of course, the maximum. If water is taken from the boiler little by little, then it will be heated in operating mode, without force majeure. Based on this, the capabilities of the boiler can be judged by its capacity:

• 2-10 l - wash hands and wash dishes.
• 30-50 l - take on hastily shower.
• 100 l - wash thoroughly in the shower.
• 150 liters or more - you can take a bath and connect a washing machine to the hot water supply.

Note: if you already have it, it is advisable to leave it by turning off its machine. It will make a good hot water accumulator, and in case of problems with the gas boiler, you can turn it on.

Documents for the boiler

Suppose you equipped a furnace in compliance with all requirements. Buying a boiler It is too early. First of all, check if the old papers have been lost for gas, and take them out into the light of day:

1. Contract for the supply of gas, if the boiler is heating. Subconsumers may only install hot water boilers.
2. All documents for the gas meter. Any boiler cannot be installed without a meter. If it doesn’t exist yet, there’s nothing to be done, you need to set it up and draw it up, but that’s another topic.

Now you can buy a boiler. But, having bought, it is too early to install:

• In BTI, you need to make changes to the registration certificate at home. For privatized apartments- through the organization operating the house. In the new plan, a closet under the boiler should be applied, and clearly marked: “Furnace” or “Boiler Room”.
• Submit an application to the gas service for the project and specifications. As part of the required documents and the technical passport for the boiler, so it must have already been purchased.
• Install the boiler (see next section), except for the gas system. This can be done while the gas workers are preparing the project, if the premises are approved.
• Call a specialist to make a gas piping.
• Submit an application to gas workers for commissioning.
• Wait for the arrival of the gas service engineer, he will check everything, draw up a conclusion on suitability and give permission to open the shut-off gas valve to the boiler.

Note: gas workers are not supposed to give permission to private individuals to work on gas equipment. Therefore, to connect gas to the boiler, you will have to call a specialist or then “resolve the issue” with the inspector during commissioning. As a rule, the first one is cheaper.

Boiler installation

Adjacency of the boiler body close to any of the walls is unacceptable; it is forbidden. After installing the boiler in place, it is tied up - connecting three systems: gas, hydraulic and electric. The gas piping should be done by a gas specialist as indicated, and lastly, when everything else is already connected.

Electrical and hydraulic piping can be done independently. Here is the main guidance document– instructions for the boiler. Typical scheme hydropiping of the boiler is shown in the figure. For any boiler, the following conditions must be strictly observed:

1. Water and hot gases in the boiler heat exchanger must go countercurrent, otherwise it can simply explode with any automation. Therefore, it is extremely important not to confuse, through negligence or for the sake of ease of installation, cold and hot pipes. After hydrobinding, inspect the entire system carefully again, then rest for an hour, and inspect again.
2. If in heating system antifreeze was filled, drain it completely and flush the system twice clean water. The admixture of antifreeze in the water entering the heat exchanger is also explosive.
3. Do not neglect the "mud filters" - coarse water filters. They should be located at the lowest points in the system. The accumulation of dirt between the thin fins of the heat exchanger also creates a dangerous situation, not to mention exorbitant gas consumption. At the beginning and at the end heating season drain the sediment through the sumps, check their condition and, if necessary, flush the system.
4. If the boiler has a built-in expansion tank and a de-airing system, remove the old expansion tank, and close the old air valve tightly, after checking its condition beforehand: air leakage will also create a dangerous situation.

Outcome

Installation of a gas boiler is technically and organizationally complicated. You can install only the simplest water boilers or expensive, fully automated home boilers on your own. But the connection of the boiler to the gas supply system (gas piping) must still be carried out by a specialist in the gas service or a certified installation organization. Otherwise prohibited by the rules for the installation and operation of household gas appliances.

Today, a person can use one of the many various ways provide warmth to your home. The most common option is, of course, the installation of wall-mounted gas boilers. Despite the relatively recent appearance of wall-mounted devices, they have gained quite a high popularity. Sometimes such devices are simply called mini-boiler rooms, because in a small building there are many very important elements. But for the equipment to work correctly, you need to know how to install a gas wall-mounted boiler.

Wall type gas boilers are the most popular

Design and application of wall-mounted gas boilers

Inside such a boiler are located:

• heat exchanger, which is equipped with a boiler and burner control device;
• circulation pump;
• expansion tank;
• safety system.

The device of a gas boiler and the trailer of its operation

Also there are many other elements. But when is the best time to install such boilers? Firstly, such a boiler is more suitable for installation in cottages and country houses that are equipped individual systems heating. Since this kind of boilers have 12-42 kW of power, and one kilowatt is able to heat 10 square meters premises, the list of buildings in which the device can be used is very extensive. So such a boiler will work effectively in rooms with an area of ​​\u200b\u200band 450 squares. But the main advantage of a wall-mounted boiler is its price, which is almost two times lower compared to floor counterparts.

Secondly, the ease of installation of equipment should be added to the advantages, which has a good effect on the cost of installing a boiler in a house. Thirdly, do not forget about such a component as appearance, allowing you to build a wall-mounted boiler in almost any interior. Fourth, it is worth noting the comparative small size devices.

Among the promising areas for the development of this kind of boilers, heating in apartments located in urban areas should be noted. high-rise buildings. The reasons for this are quite simple, because the repair of heating mains through which the coolant circulates is a very costly business. In addition, the loss of thermal energy here is much greater than when using boilers in each apartment. If the owner of the apartment will have his own boiler, then he will have the opportunity to set the temperature that he considers comfortable.

Features of installing wall-mounted boilers

Installation of such a heater is a rather laborious process that must be carried out by specialists in compliance with all the rules for installing wall-mounted gas boilers. Boilers can have one or two circuits, and in the first case, the boiler will provide the house with heat, and in the second - also hot water. Such boilers can be divided into turbocharged and atmospheric. In any case, depending on the technical characteristics of wall-mounted boilers, they will have various features installation.

Installation of a gas boiler must be carried out by a specialist in compliance with all rules

For example, if we talk about double-circuit gas boilers, then they require more attention during installation, because they connect both heating and hot water supply lines to them. Thus, when connecting hot water to the boiler, you need to make sure that all plugs have already been removed from the system. Among other things, it is worth paying attention to the junction of pipes. After all, the fittings at the junctions must have sealing gaskets, and threaded connections must be tightened as tightly as possible.

It is worth remembering that there are boilers with open and closed combustion chambers.

• So, in the first case, smoke and combustion products are removed naturally.
• In a closed chamber, a fan is used to remove smoke.

For boilers with an open chamber, combustion air is taken directly from the room. But for him correct operation it is worth following some recommendations.

Before connecting the boiler to the previously installed chimney you need to make sure that it is clean, because during operation, dirt can fall off and block the exit of combustion products. This is a dangerous situation that can end in serious problems. The connection of such a boiler with the existing chimney in the room must be carried out exclusively with a metal pipe that is resistant to high temperatures, mechanical wear and aggressive media such as combustion products and condensate.

After installing the boiler, it is necessary to check the correct connection of the outlet pipes.. Before turning, at the outlet of the boiler, the vertical section of the connecting section must have a length of more than two pipe diameters. After that vertical section the pipe must have an ascent, the slope of which must be directed towards the boiler. The connection of the boiler to the chimney should be carried out with the shortest length of the pipe.

Closed combustion chamber

Speaking of boilers closed camera, it is worth mentioning that the products of combustion are removed here with the help of a fan. Air for the combustion process is taken from the street. Such a boiler does not need to be connected to an individual chimney. It can be vented to a collective chimney or with a coaxial chimney that is built into outer wall. The main thing is to ensure that during the installation process, dirt does not get into the installation site of the fan. It is better to check this place before starting.

A boiler with a closed combustion chamber does not need to be connected to an individual chimney

It is worth making sure that the fresh air intake pipe is at a height of at least 220 centimeters from the ground, and that it protrudes at least 18 mm from the wall. It is worth paying attention to the position of the pipes of the chimney system, which must necessarily have a downward slope. This is done so that the condensate formed during combustion is removed from the chimney. The space between the pipe and the wall must be carefully sealed. This will prevent rainwater and dirt from entering the house through this hole.

It must be taken into account that there should be no obstacles at least 15 centimeters in front of the gas outlet pipe. Structures located above the pipe should be at a height of 25 centimeters or more. Otherwise, the flow of exhaust smoke will be disturbed, which may lead to incorrect operation of the boiler or cause an emergency. And finally, you need to make sure that the air outlet pipe is not loose or clogged.

Before installing a wall-mounted boiler, you must notify your local gas supply authority of your installation plans. In the same place, all the necessary actions and the scheme for installing a wall-mounted gas boiler are coordinated.

Your new boiler

When buying, be sure to check the completeness of the delivery. The device after unpacking should have a perfect appearance, and the instruction manual should come with it. If any of the parts or components are missing, it is imperative to contact the suppliers and solve the problems that have arisen.

Need to check specifications indicated on the plate on the boiler itself and on the equipment box. It is also worth making sure that these indicators correspond to the numbers indicated in the instruction manual. Before installation, it will be necessary to clarify whether the device will work normally with the type of gas supplied.

The first start-up of the boiler under the supervision of a specialist

How to install?

The boiler must be prepared for installation. Before installing a gas wall-mounted boiler, it is worth flushing the pipes from foreign particles. Once in the system, they can disable it.

Do not forget about the preparation of the heating system, which boils down to flushing radiators and lines. The wall-mounted boiler is installed exclusively on a level vertical surface, which is able to withstand the weight of the boiler itself and the additional equipment connected to it. Here it will also be necessary to take into account the material from which the wall is made, as well as the bearing capacity of all fasteners.

If the boiler is installed on a combustible wall, it is necessary to install a sheet of material under it that does not burn and has a thickness of more than 3 millimeters, while the boiler itself is placed at a distance of 5 cm or more from the wall.

It is very important to organize separate wiring for a wall-mounted gas boiler with a stabilizer and a switch. In addition, this system must be provided with grounding. The boiler must hang on the wall evenly, without distortions.

Before implementation installation work it is worth providing the necessary space on the wall for installation. Between the boiler and the ceiling, the distance should not be less than 500 mm, and from the boiler to the floor, it is worth ensuring a distance of 800 mm. The first start-up, as well as the adjustment of the boiler and all related equipment, must be carried out in the presence of a specialist.

Introduction

Wall-mounted gas boilers are very popular among owners autonomous systems heating. Since the fuel used in them is very explosive and poisonous, it is necessary to approach the installation and commissioning of these devices with all responsibility. Installation of a wall-mounted gas boiler in a private house should be carried out in strict accordance with the technical requirements and standards.

Installation, in relation to hinged gas boilers, the concept is very voluminous and may include such work as: the correct choice of location and the actual installation of the boiler on the wall, connection to the gas main, piping in the heating system. In this article, we will deal exclusively with right choice premises and placement of the heater on the wall, as well as the existing requirements for these works.

Is it possible to install a gas boiler with your own hands?

When designing a heating system, one should take into account the requirements of gas services, which they impose both on the installation site of a wall-mounted gas boiler, and on the installation process itself. If all technical requirements and building codes are observed, in some works it is allowed to do it yourself.

It should be remembered that it is only allowed to independently place the wall-mounted boiler in the prepared room in accordance with the project developed by the gas service. Connection to the gas main and all commissioning work must be carried out by certified specialists who have permission to carry out these works.

We also note that not all manufacturers allow the installation of gas boilers with their own hands. Many large companies producing heating gas equipment, such as Bosch, Ariston, Viessmann will void the warranty for the wall-mounted boiler if the installation was carried out by an unqualified person.

How to choose the right place for installation?

Depending on the design, the requirements for the installation of mounted gas boilers are somewhat different. If installed heater with a closed combustion chamber, it can be placed almost anywhere in the house. For gas boilers with an open combustion chamber, the requirements are more stringent and a properly equipped boiler room should be provided for them. General requirements imposed by regulatory documents (SP 42-101-2003, SNiP 42-01, SNiP 31-02-2001, MDS 41.2-2000) and controlled by gas services are the following:

1. When installing household hinged gas heat generators with a power of up to 60 kW, the volume of the room in which the installation is carried out must be at least 15 m³. Mounted boilers with an open combustion chamber must be placed in a separate room on any floor of the building. Turbocharged heaters with a power of up to 35 kW can be installed in the kitchen.
2. The room in which the installation is planned must have a ceiling height of at least 2.5 m. If a model with an open combustion chamber is used, it is required to equip it or other suitable material.
3. The boiler room or kitchen where the mounted boiler was installed must have a window with an area of ​​at least 0.03 m² for each cubic meter premises.
4. When installing wall-mounted gas boilers with an open combustion chamber, it is important to ensure proper ventilation. The hood should produce three air exchanges in the room for an hour, and forced ventilation replenish the volume consumed by the hood plus supply the air necessary for normal operation burners.
5. The external gas pipeline is supplied directly to the room where the boiler is installed. The section of the pipe passing inside the premises must comply with the requirements of SNiP 2.04.08 for low-pressure gas pipelines.
6. It is necessary to provide a point of connection to the mains with earthing and artificial lighting. The temperature in the boiler room should be in the range from +5 to +35 °C with air humidity not exceeding 80%.

How to place a gas boiler on the wall?

Having correctly selected and prepared the room for installation, it is necessary to determine the position of the wall-mounted gas boiler on the wall and prepare the surface for installation accordingly:

1. Installation is recommended to be done on a solid wall that can support the weight of the device. If the wall is made of combustible material (for example, wooden house), then between the boiler and the wall there must be a gasket made of non-combustible material protruding along the perimeter of the appliance to a distance of 200 mm. Usually, a layer of asbestos cardboard is used as a layer, and a sheet of galvanized steel is attached on top of it.
2. The hinged boiler is recommended to be installed at a height of 90-120 cm from the floor and at a distance of at least 10 cm from adjacent walls. This space is necessary for comfortable strapping and after-sales service boiler.
3. The electrical outlet must be located next to the wall-mounted boiler and in no case below it. This will avoid short circuit in case of leakage. Nearby should provide a place for.

The requirements for the location of gas boilers on the wall and the distances to various structural elements are different for many models. We have given the most typical values, but still, before performing the installation, it is necessary to clarify them in the passport for a specific device.
