In order to ensure your home or apartment in economical heat and hot water At any time of the year, you can install and connect a double-circuit gas boiler, but how to do it right, only specialists know. With the help of one element, serious tasks are solved. Therefore, recently, such aggregates are very popular among the owners. country houses. Connecting such an installation is a difficult process, but if it is sorted out, you can do everything yourself.
In most cases, aggregates are found, which are capable of heating in one minute of 6 liters of water. This indicator can be quite considered not bad. True, it is possible only if you implement correct installation Installations.
The principle of work is based on the presence of two categories from each other. The first is responsible for the heating of the house, and the second is for hot water in the crane.
To connect the installed boiler, you need to take into account the presence of several systems in the room at once:
Installation and connection of the two-door starts from installing it on the wall. For this, special brackets are used, which in most cases are supplied with the equipment. The main thing is that you need to take into account - fasteners should be in an ideal horizontal plane, and therefore it is necessary to have a level.
After installing fasteners on the wall, the boiler itself hangs. All this is done with your own hands. To disobey any error, at first you can view a few videos, which are set in the network. They show the installation of different systems.
There are several rules that need to be followed when choosing a room for installing the unit:
Usually connecting such devices is equally. The only thing that may vary is the location of the nozzles. But it is not often found.
Due to the fact that many different models of gas boilers are presented on the market, to tell about all specific installation schemes is difficult. You can only single out the main nodes that must be present so that the unit is not only easy to install, but also use in the future.
Key points:
Installation should be started with the installation of the cutting valve and filter on the water supply. This will help pass through the unit only purified fluid, which in turn will significantly extend the operational period.
The valve is necessary for a situation where you need to close the water supply to replace the filter, cleaning system or repair.
After that, the nozzles of the heating system and hot water are connected. There is nothing complicated here too. First, cutting cranes are connected, and then a connection is connected to the boiler.
A homemade wall boiler is necessarily equipped with a pump that provides uniform heating of all radiators indoors. This device needs special strapping. Wall-mounted models Energy dependent, and therefore, any current shutdown instantly reduces the efficiency of work. Outdoor models are capable of working without such pumps, as they provide special elements for creating natural pressure.
Centralized heating on schedule, unfortunately, not available in all houses. Homeowners in the private sector are forced to independently concern that winter in their home was warm, and hot water From the crane flowed regardless of the season. Many solve the problem by installing a gas boiler. However, this procedure in a private house is not so simple and associated with a number of requirements and rules. We will tell about them in the material.
Gas boiler - this is a reduced size of the boiler room, equipment that produces thermal energy Due to the consumption of natural gas. Used for heating rooms, heating water water For household and household needs.

| With Piezorozhig | Enabled with button in manual mode |
| By character traction |
|
| With natural hand | Air fence comes from the same room |
| With forced tag | Air using the built-in fan is closed from the atmosphere |
When choosing gas equipment Key requirement - thermal power. It is calculated individually for each home ownership.
For moderate latitudes, this is done by the formula: The area of \u200b\u200bthe house is multiplied by 100 W plus 20% of the resulting digit for stock. If the height of the ceiling arch exceeds 3 m, the power is considered as a cubature multiplied by the average value of 40 W.
In regions with mostly low temperature regime The area of \u200b\u200bthe building is multiplied by 120, and in the hot regions - by 80. The increase in the reserve factor remains unchanged.
Using double-circuit boiler Or the tandem "boiler boiler" in the reserve add 50%. If a buffer container is connected in the diagram, then this indicator doubles (up to 100%).
The best options for matching the boiler type selected room are assembled in the table:

Before making a final decision on the installation of pretty expensive equipment, you need to carefully examine the official documents. These are standards that regulate the procedure for the use of gas boilers by the population.
They have a common name "Construction standards and rules" (SNIP), contain general rules and specific clear requirements for those who want to equip house boiler rooms.
The main profile slips where you can find all the information you are interested in are collected in the table:

In order to establish gas equipment in private home ownership, you need to successively perform the following steps:
Usually, the development of the project and the installation of the equipment is carried out by the employees of the company supplier of natural gas. As a rule, it is state structure. However, it is not forbidden to contact private organizations. The difference is only in the timing and cost of work.
It is necessary to fulfill in order each item so that the heating in the house appears. Correctly performed actions - the key to the rapid coordination of documents and starting equipment.
According to construction standards, the gas mini-boiler room is allowed to be installed in the following types of rooms:

Optional but desirable condition It is the installation in the gas analyzer room and the emergency shutdown system in the case of a possible fuel leakage. For ventilation, you can make a trifle air duct, equipped with a grid, in the door of the room or on the adjacent wall on the other room.
Calculating the parameters It is important to take into account the amount of the supply channel. It is equal to the volume of the drawing taking into account the amount of air mixture specified in the technical passport for burning.
In private houses, the kitchen is suitable for these requirements.which, as a rule, designed in advance by the same type as boilers.

For construction standards and rules, gas appliances in a private house, including boilers, are prohibited to install:
In the case of use as fuel liquefied hydrocarbon gas, it is forbidden to install a boiler in the premises of the basement.
A lot of disputes and discussions are built around the possibility of installing gas supply equipment in the private house toilet. It is completely excluded in the case of mounting the boiler with open system combustion.
Acting in Russian Federation Snip 31-02-2001 is prohibited accommodation gas devices Any type in the bathrooms. However, at the regional level, their requirements and norms that may be softer and loyal in this matter can be taken.
So, in some subjects of the Russian Federation, if the combustion chamber of the device is closed, does not communicate with air indoors, then such installation is possible. At the same time, the oxygen fence for combustion from the outside should be carried out only through sealed pipes. You can learn about local rules by contacting the municipal gas service or urban licensed design organization.

The next step is to order and manufacturing project documentation On the installation of a gas supply device in private household. The project includes schemes:
Ready Document for agreeing to the relevant department of the state organization, endowed with the authority to control fuel and energy (most often it is Gorgaz). The procedure takes from 10 days to 2-3 months, depending on how difficult project.
In the mandatory package of documentswho require Gorgaz employees, enter:
When buying a gas supply device, check the presence of all these securities. If for some reason there are no reasons, you need to request copies from the representatives of the boiler manufacturer.
The owner may also require the layout of the building in the updated state. If there is no, the technician for an additional fee will take place and will be the actual diagram of the drawing. At the same time, gas workers take into account the wishes of the owners for the intended place of installation of the boiler.

According to the results of the consideration of documents, one of the two verdicts may be made:
In the case of a favorable outcome of the consideration of documents at this stage, you can order the laying of internal and external communications.
Installing the boiler without permission will be dangerous and illegal. In the event of a detection of such unauthorized installation, the home owner will be brought to justice and will pay an impressive monetary penalty.
Mounted gas equipment
Machine installation work on the placement of the device to the prepared section of the floor or wall, its connection to ventilation and the output of the chimney of the homeowner can be performed independently. but sostly enough to entrust the performance of these works by professionals from specialized organizations.
Direct fastening and installation of outdoor equipment is carried out taking into account such rules:
When installed on the wooden floor under the device, a non-controlled material is placed: roofing steel or basalt cardboard. With 3 sides, the lining protrudes for the dimensions of the device by 10 cm, in front - 70 cm is longer. The walls are also trimmed with mineritis plates, asbestos sheets or galvanized sheets with a thickness of more than 1 mm.

If the boiler is mounted, then the minimum indents must have the following values:
The mounted appliance indoor from the tree is also isolated from the walls by a non-aggravated material by 100 mm protruding for dimensions. The length of the steel or asbestos gasket must be below the length of the boiler 700 mm. Thickness insulating material Ideally is 3 cm and more.
Self simple conditions Expansioned when installing the parapet device. The key requirement is to indoors the window and door Piece More than 80 cm. This boiler is also considered as the safest, because the ventilation system and chimney is enclosed in one pipe.
The house by definition should be warm. Ways to make it so many. However, each owner strives to do this most economical and practical method. One of these options is the installation of a gas boiler. Heating gas is beneficial and easy enough to install and operate. Connecting devices should only be carried out by specialists, but the arrangement of the boiler room, the installation of the boiler, etc. You can also spend on your own, while saving a decent amount.
Installation of gas equipment should be started with obtaining permits and necessary coordination. It is necessary to order a project to gasify the premises, installation of gas equipment. The document is developed and approved by specialists from the gas supplier company. Having become acquainted with the project you can start buying necessary equipment, the main characteristics of which should be present in the document. In addition, an agreement should be concluded on the supply of natural gas. After that, you can engage directly by installing the system.
Gas boiler is the main element of the heating system. To install it, it will be necessary to competently equip the room. It must comply with a number of strict requirements, the violation of which entails significant penalties and provoke accidents with the most severe consequences. Gas is an explosive and combustible substance. You need to be extremely careful with it.
The room in which gas equipment is installed must be responsible for a variety of requirements. The main characteristics of the boiler room are represented as a scheme
When choosing a place to install a heating gas boiler, you need to consider the following room requirements:
It must be remembered that the installation of gas boilers with a capacity of less than 60 kW is allowed in any room, except those that are intended for accommodation. It is also not recommended to install gas equipment in the bathroom or bathroom. Double-circuit devices are prohibited to mount in the kitchens. If the total capacity of the equipment is not above 150 kW, it can be put on any floor of the building. The larger power devices can be located only on the first floor or in the base.
Many prefer to place gas equipment in the kitchen. In this case, the norms regulating the installation of gas boilers require to calculate the necessary minimum area based on 1 kW of power accounted for at least 0.2 m 2 rooms. If the kitchen is combined with the living room, the presence of a gas analyzer becomes obligatory, which can notice a possible leakage of gas in time.
If the boiler power allows, gas equipment is often installed in the kitchen, even if it is combined with a living room. In this case, the presence of a gas analyzer becomes a mandatory precautionary measure
To install the boiler without complications, it takes to pay attention to the method of its attachment during the purchase of equipment. You should check the device's equipment and find out the presence of fasteners. If they are not, it is necessary to immediately buy suitable. In addition, when buying equipment, be sure to check the availability of a certificate. In the absence of a document, serious problems with registration are possible. The characteristics of the device and the serial number applied to the inner door of the device must coincide with the information specified in the passport.
Before installing an outdoor device, you should prepare a place for it. Let's start with the floor. Since the equipment has a lot of weight, the base must be durable. Perhaps you will need to fill the screed. The floor to which the boiler will be installed must be made of a non-aggravated coating material. If this is not the case, the hollow concrete blocks with a height of 100 mm are stacked over the floor and covered on top of a metal sheet with a thickness of 0.8 mm. As an option, you can consider the use of refractory plates permitted to use for such purposes.
Regarding the wall, the instrument must be set at a distance of at least 0.1 m, provided that the coating is made of non-combustible materials. If it is necessary to move the device closely, the wall should be refractory. In this case, the base is insulated with roofing steel, which is superimposed on a sheet of asbestos with a thickness of at least 0.3 cm. Isolation must overlap the dimmer of the device's envelope for at least 0.1 m. All protruding parts of the boiler fittings or gas burners Must be removed from the wall at least 1 m.
The equipment is installed on the prepared basis as soon as possible. For checking used building level. If necessary, under the feet of the device, a solid non-flammable material is lined. The boiler connects to chimney and domesticated heating system. To prevent the rapid clogging of the heat exchanger before entering the input, the hard cleaning filter is installed. If the boiler is double-circuit, it is connected to a pipeline with cold water.
Outdoor gas boiler must be installed on a prepared base. The floor, if necessary, is enhanced and the basis of non-combustible materials is established. Most often it is hollow concrete blocks with a height of 100 mm, covered with sheet metal
Specialists recommend installing the boiler so that it can be easily dismantled. All pipes made to the instrument are installed, stop valves are installed. They will enable if necessary to dismantle the equipment without unwanted reset of water from the operating system.
It should be remembered that with your own hands the full installation of gas boilers cannot be produced. A certified specialist must be invited to be invited, which will check the accuracy of the installed installation, will fulfill the remaining necessary events and will start the system.
Competent installation of gas wall boilers begins with washing inner tubes. In them, during the assembly, a different small garbage could well get, which must be deleted. To do this, from the device remove the stubs necessary when transporting and under low pressure passes through it water. After washing, the equipment is ready to install.
The wall where the fixation of the device is planned, should be very smooth and strong enough to withstand boilers and related instruments. If the base is made of combustible materials, it is fastened to the non-combustible gasket with a width of at least 3 mm. In this case, the boiler is fixed at a distance of at least 4.5 cm from the wall. Installed instrument Must be at a distance not less than 20 cm from other equipment or flammable materials. It is not recommended to place a boiler near the window or in a small wall opening. Electricity source must be near the device.
The device is fixed on the planks that are attached to the wall at the desired height. It is usually located ranging from 0.8 to 1.6 meters from the floor. After fixing the device, the installation horizontal is checked using the level. All identified inconsistencies are adjusted, otherwise it can be negatively affected by the equipment. Connecting to the water supply. Before that, plugs from nozzles are removed. In water inputs, it is advisable to put filters, so the heat exchanger will be clogged less.
The wall gas boiler must be installed exactly horizontally, the accuracy of installation is necessarily checked by the level. Otherwise, problems are possible with the operation of equipment, right up to emergency situations
The gas pipeline is connected to the boiler only with a metal pipe with a rigid connection or through a special Sgon. Paronit gasket is used. Directly connecting the system is made only by certified specialists who will be checked how correctly the boiler is installed, and the equipment will be launched.
Heating gas efficiently and economically. However, do not forget that the gas is potentially dangerous. No need to try to produce self installation Gas devices without special knowledge and skills. Error price may be too expensive. Regardless of who installed the equipment, the connection is carried out only by the specialists of the gas company. They also check the accuracy of the installation made. Do not save money on professionals. Even if it may seem that the cost of their work is too high, believe me that the life and safety of everyone who lives in the house is much more expensive.
When buying a gas boiler, many want to save and make it mounting themselves. Is it possible to do this? In some cases, yes, but completely do without specialists will not work yet. After all, gas is explosive fuel, and its connection by persons who do not have a special license is illegal. The remaining work on the installation of a wall gas boiler can be carried out without attracting specialists, but it should be considered all the requirements of the corresponding SNIP-s.
Note that not all manufacturers allow independent installation. For example, ARISTON, VIESSMANN, BOSCH is recommended to resort to specialist services of only their service centers.
BAXI, FERROLI, ELECTROLUX is loyal to the issue of installation and allow the installation of the gas wall-mounted heating boiler with their own hands.
Therefore, before buying a particular model, read the documentation and specify whether this unit can be installed on your own.
Note! The first thing before starting the installation work should develop a project and approve it in the relevant supervisory bodies.
Requirements for the room in which the wall gas boiler has, depend on the type of combustion chamber: open or closed.
Open chamber of combustion Uses air for the combustion process from the room, in which the heating system is located, and the exhaust gases are removed through the chimney. Such gas boilers Require a certain amount of air, otherwise the gas does not burn and forms poisoning toxic substances. Therefore, the operation of aggregates with an open combustion chamber is permissible only in a separate room, which is called boiler room or flue. It is necessary to provide a window to possibly carry out an area of \u200b\u200bat least 0.5 m². Walls of the boiler room must be decorated with fire-resistant materials.
The volume of the furnace depends on the power of the gas boiler:
The connection of the boiler and ordinary chimney produce by using iron pipe A certain cross section. It should be resistant to influence high temperatures and toxic combustion products. When installing the connecting pipe, such rules must be performed:
Closed camera type combustion It is suitable if there is no possibility of a separate furnace device. Included with such boilers there is a coaxial chimney, which is easy enough to install yourself. It is a design of two pipes, one of which is inserted into another. With a closed type of combustion chamber, the air comes from the street through an external pipe, and combustion products go into the atmosphere through the inner.
If you chose a gas boiler with closed chamber Combustion, then keep in mind that such equipment will require an electrical power connection to ensure the supply of a fan that creates an air flow of coaxial chimney.
Gas units equipped with closed combustion chambers are considered more secure and environmentally friendly, so they can be placed in the bathroom, kitchen or storage room.
Before starting work, you will definitely read the appiled by the manufacturer. installation instructions for wall gas boiler,since different models can have their own nuances and installation subtleties. If this is not done, the wrong connection will lead to a different kind of leakage or to the fact that the boiler will not be able to work at all.
Installation on the wall
The first stage includes a mount on the wall. The boiler is hung on a special bracket, which manufacturer usually puts into a set with the device. Sometimes it happens that the attachments from the kit are not suitable, then it is necessary to select suitable parts. Also, when installing the gas unit, the type of wall takes into account - depending on it, the fasteners are chosen.
The bracket is fixed in such a way that it can withstand the mass of the equipment and ensure an even position.
The segment of the wall, which is behind the unit, must be protected by a non-splashable material. Installation of a wall boiler should be performed so that from the floor the unit is not lower than 80 cm, and the gap between its rear surface and the wall was at least 5 cm.
Note! Will help make a special cardboard pattern. It can be placed on it all the necessary attachments and a mixing with chimney. The pattern applied to the wall and all markers are transferred to the wall. After that, it is cleaned.Connecting heating and water supply
The second stage is the connection of heating and water pipes. Their number depends on how many contours in the boiler. Before installing, do not forget to remove the plugs from the nozzles. On pipes through which water will be received from the heating line, you should put the filters to prevent the clogging of the system with mud or garbage.
The quality of water is important - if it is rigid, you will have to install cleaning equipment, for example, polyphosphate dispensers.
Pipelines of the boiler with pipelines are connected using a threaded coupling. For dense fixation, fum-tape is used.
Connecting boiler to gas
Perform the third stage - connect a wall gas boiler to a common highway, can only a specialist of the gas service or an organization that has a license to carry out similar works.
An independent connection is illegal, besides, it can lead to an irreparable tragedy. Therefore, please contact the gas service. There will be a technical specifications for connecting to your equipment.
Gasification can be carried out underground and above-ground method. For underground, pipes from polyethylene are used, which are very racks for corrosion. Overhead method provides for use steel pipeswhich are built next to the location of the gas boiler at an altitude of 1.5 m from the floor.
If there are several in the house heating devices, Gas fade to each of them separately. Inside the premises lay the highway is prohibited.
Sealing of all pipelines compounds are performed using paint or pacle. A gas filter must be installed on the crane that protects the boiler from garbage and condensate.
Connecting to the electrical stroke
Fourth stage - connecting the unit to electricity. Many modern models Wall gas boilers are equipped with a complex automation system. It allows you to manage the work of the boiler without the intervention of the owner, and also controls security.
Dual-circuit units produce in two versions: with a power outlet and cable to connect to the machine.
If you bought an assembly with a regular fork, it should be placed closer to the outlet. According to the safety requirements, it should be placed near the boiler, and not under it. It is necessary to avoid a short circuit that can cause a coolant leakage from the device.
The gas unit requires a mandatory grounding. To do this, acquire a set of point grounding, which can be placed in the basement at home or next to it.
In order for the automation to serve for a long time and fails, it is necessary to provide an aggregate with a stable voltage without significant drops. If this condition is not performed, the stabilizer will have to buy.
For details on the installation and connection of communications to the wall gas boiler, see the video.
The first launch of the wall gas unit should be carried out by a specialist. It will configure the boiler for a certain mode and check the correctness of his work.
Before starting the unit, the unit is slowly filled with water until its pressure in the system is 2 atmospheres. The tightness of all available connections is carefully checked. In the process of commissioning work, the specialist can ask all your questions about the operation of the heating device.
If the boiler works correctly and everything is in order, sign act about the commissioning unit.
You purchased a new gas boiler for a private house and it's time to take him your place in the furnace. For this you can hire specialized firm Or contact the appropriate service. But the cost of installation in this case will noticeably blow on the wallet, while it is possible to reduce the process. Yes, some operations have the right to fulfill only licensed organizations, but it is only half of the work, with the rest you can cope with yourself. Here we will tell about how to install a gas boiler in a private house from beginning to end.
Since there is no compliance with certain rules for the installation of a new gas-wide equipment, it is worth ordering all the work requiring license, the gas service:
The remaining actions you can do on your own. First you need to get in the gas service. Technical conditions for installing gas equipment. Check out them or remove the copy and immediately order the project documentation. When she is ready, it will need to be coordinated in the gas service. As it is not difficult to guess, this procedure is a clean formality, after it is completed, a brigade will arrive at home and install the gas boiler in terms of its connection to the fuel line, which will be compiled by the corresponding act.
All that remains to make you is to perform strapping and connecting to the heating system, the power grid. There will be the opportunity to save money, or doing everything with your own hands, or with the help of familiar plumbers. The last stage is the final execution of documents.
This is only a brief description of one of the possible algorithms for solving the problem, but in fact not everything is so simple, because gas boilers should be established in compliance with regulatory requirements, it will not hurt them to get acquainted at the stage of selecting the heat generator.
First of all, it is necessary to take into account all the requirements for the room, where it is supposed to place the source of heat. Options are:
In the kitchen, the installation standards allow you to place an outdoor or wall-mounted aggregate with heat-producing 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 an extension. At the same time, it is important to observe the size of a separate room or the attached part, they cannot be less than written in standards. The minimum regulatory height of such a room is 2.5 m for any power under the specified limits.
Note. The magnitudes of thermal power prescribed in the standards and affecting the installation conditions of the boiler are the total capacity of all the aggregates in the boiler room, including the operations of the DHW.
For heat generators with a capacity of up to 150 kW in accordance with the norms, the smallest room for installing the gas boiler is 15 m3, in addition, for each kW water Heating Equipment 0.2 m3 is added to this volume. If the total indicator of all aggregates exceeds 150 kW, then the size of the room is not rationed. But the installation rules and safe operation Boilers, according to which it is necessary to withstand technological lumeges between the aggregates and walls of the room, they are accepted for considerabilities for maintenance and access to all systems in the boiler room. The size of the passages in accordance with the rules are observed as follows:
For a kitchen, where not too powerful heating equipment is allowed (up to 60 kW), it is not the most stringent requirements for the installation of gas boilers. It is only necessary to comply with the standard in terms of the volume above, and also provide air exchange in an amount 3 times in 1 hour. Additionally, it is required to feed the dying air for combustion of fuel, its consumption for each unit is specified in specifications. This standard is valid for all types of boiler rooms.
Note. For heat generators with a closed chamber of the installation rate of gas boilers, it is not forced to ensure the supply of an air mixture to burning, as they take air directly from the street through coaxial chimneyWhat will be said below.
In regulatory documents, it is proposed to organize ventilation for the boiler in the kitchen using an exhaust mine and a supply grid embedded in the front door. The passage section of this lattice is also normalized, its area cannot be less than 0.025 m2. In the same way, you can arrange air exchange and in separate furnaces. Fresh air supply difficulties may occur in basement or basement floors, it is possible that for compliance technical conditions You will need to put a special trim fan.
In boilers, located on the first, basement floor or in an extension, we need window openings with a glazing area of \u200b\u200bnot less than 0.03 m2 per cubic meter of room volume. To the attached room, the requirements for fire resistance of walls, a separate foundation and entrance doors. In addition, the extension cannot be built on the front facade of the building, and during the construction you need to retreat from the nearest window or door 1 m horizontally.
It should be noted that the requirements for the gas boiler located in a wooden house are identical to the standards for structures from other materials, that is, the rules of the boiler room device are one for all buildings.
When the appropriate room is selected and performed under it project documentation, It can be started to own the heat generator in place. To do this, you will need a scheme for connecting a gas boiler in a private house, which must be present in the project. It shows the installation location, distance to all enclosing structures and technical requirements for the production of work.
Often the installation of floor gas boilers requires the foundation device. In many cases, he 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 mass of equipment is greater than this value, then you will have to prepare the basis. To do this, you need to destroy the existing screed, pour the pillow from the rubble and carefully to take it. Then to associate a grid from the reinforcement of the periodic profile with a diameter of 8 to 12 mm, put it on the finished base and pour concrete.
To withstand the gas boiler installation technology, the size of the foundation in the plan should be 50 mm to exceed the equipment dimensions, and in height of it performs by 50-100 mm above the screed level. Full frost concrete slab You will take at least 2 weeks, it is necessary to take into account when planning work.
Further, from above, the foundation is put a non-aggravated gasket from asbestos or metal and put a heat generator on it, adjusting the legs of the unit in such a way as to withstand a clear horizontal. After that, using the installation scheme of the gas boiler, it is connected to all engineering networksexcept the fuel line. This connection, as mentioned above, carries out a licensed organization.
To carry out the installation of a wall gas boiler in a private house, not a foundation, but a solid base in the form of an outer wall, which is able to withstand the weight of the aggregate. First of all, it makes a markup, showing where the heatgenerator itself will be suspended and in what place the chimney pipe will be released. Then, with the help of the perforator, a through hole is drilled in this place in which a metal sleeve is inserted.
There are no special difficulties in having a wall-mounted gas boiler. If the action takes place in the kitchen in an apartment or house, you need to take measures to protect the furniture from the garbage and then proceed to the fastener process. Difficulties may occur when installing heavy units, whose power reaches 120 kW, do not do without assistant.
Note. When the mounted boiler is attached to a wall consisting of a combustible material, then you need to make a special bracket, which allows you to make a lumen of 45 mm between the surface of the wall and the rear panel of the heater. Also, to the wall should be attached a sheet of non-combustible material that plays the role of a protective screen.
Lastly, the binding of the gas boiler and the chimney device is performed. Here it is necessary to be compactly placed under the body of the heat generator of the cranes and other fittings so that everything looks carefully and at the same time had the opportunity to disassemble or change any element. Therefore, when the heating scheme is made from polypropylene pipes, then the cranes and mud better use bronze, and plastic pipes Attach through threaded adapters. In this regard, it is somewhat more complicated to install a two-circuit gas boiler, where it will be necessary to pave pipes for the DHW and correctly connect them to the appropriate nozzles.
In essence, the requirements for chimneys of outdoor and wall gas boilers are identical, the difference can be in the design of the gas plant. It depends on the heat source device:
The traditional chimney for the gas boiler is arranged in the thickness of the wall or hanging outside the building. The cross section of the outlet from the unit determines the diameter of the entire chimney, it must be the same size, and better - by 20-50 mm more. Horizontal plot connecting the boiler with chimneyThe ideal is performed with a length of 1 m, the maximum allowable length is 2 m.
Below the scene is sure to need a door for cleaning and internal inspection, and the deaf end of the vertical pipe is supplied with a condensate drain system. Carrying out the installation of the chimney of the gas boiler, it is necessary to remember that the pipe is not allowed to cover umbrellas, deflectors, flora, and so on. In accordance with the standards, you can only put a narrowing nozzle.
In contrast to traditional exhaust channels for burning products, install a double-lit chimney for heat generators with a closed camera is much easier. Following B. outdoor wall The hole of the required diameter and binds the metal sleeve in it, the coaxial chimney is mounted, which is a horizontal two-axis tube of a certain length. The only condition mandatory for compliance is a small bias towards the exit of smoke. It is done in order to be condensate formed in the air path did not appear in the boiler.
So, the fulfillment of the installation and strapping of the boiler with their own hands is the problem, though not easy, but completely feasible. It will take a lot of time and patience for the design of all documentation, but the assembly works themselves will take a maximum of 3-4 days, and even less. It is important to prepare well and in advance to purchase all the missing elements of the strapping scheme, as well as the fasteners details.
