Where can I install a gas boiler in a private house? Rules and requirements for equipment. Installation of a gas boiler in a private house: requirements, rules and stages of installation work Installation instructions for a gas boiler

All other elements can be connected independently. Each boiler has almost the same details for connecting to communications:

• a coarse filter is installed on the return line of the heating circuit;

• the magnetic filter is a household water softener. He is preparing cold water before its heating in the hot water circuit;

• mesh filter;
• gas filter;

• sgons are elements threaded connection pipes;

• flexible corrugated hose;

• manometer - a device for measuring pressure;

• thermostat - electronic automatic system maintaining the set parameters;

• a coaxial chimney is a chimney that is a substitute for a traditional chimney in modern forced draft boilers;

• a 3 bar safety valve is a mechanical system for automatically discharging the coolant into the atmosphere when the pressure rises to critical values;

• the expansion tank is designed to compensate for the rise and fall of hydraulic pressure in the heating system;

• stop valves;

• automatic air vent is designed to remove air from the heating system.

When connected, all elements look like this:

The most simple system heating and hot water supply when using a gas double-circuit boiler has the same design as traditional systems:

The boiler is a flow-through heating element for hot water supply and a closing link in the heating circuit.

If you want to provide a more complex heating system, then a similar scheme can be considered in another example:

The hot water circuit remained unchanged, but additional elements appeared in the heating circuit:

• the hydraulic arrow is installed immediately after the boiler. This is a simple vertical tank. Its purpose is to ensure constant circulation of water (with a decrease in the flow of coolant to consumers), the removal of air from the heating system, the distribution of coolant with different temperatures, maintaining the temperature difference between the supply and return lines (this is a prerequisite for the normal operation of a gas boiler);
• distribution manifolds on the direct and return lines are needed to evenly distribute the coolant between consumers;
• individual circulation pumps for each heating circuit allow you to provide your own temperature regime in all rooms.

Gas double-circuit boilers have an affordable price and allow you to provide the room with cheap heating and hot water. The use of a gas unit is possible in a heating system of any complexity.

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 installation cost in this case will significantly hit the wallet, while it is possible to reduce the cost of the process. Yes, only licensed organizations have the right to perform some operations, but this is only half the work, you can handle the rest on your own. Here we will talk about how a gas boiler is installed 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 that requires a license from the gas service:

• Issuance of specifications.
• Development of project documentation.
• Production of works on connection to the natural gas pipeline.

You can do the rest of the steps yourself. First you need to get technical conditions for the installation of gas equipment in the gas service. Familiarize yourself with them or make a copy and immediately order project documentation from them. When it is ready, it will need to be coordinated with 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 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 finalization of documents.

It's only short description 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 does not hurt to get acquainted with them 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;
• a room in the basement or basement;
• in an outdoor building.

In the kitchen, installation standards allow you to place a floor 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 extension. At the same time, it is important to observe the dimensions of a separate room or attached part, they cannot be smaller than prescribed in the regulations. The minimum standard height of such a room is 2.5 m for any power within the specified limits.

Note. The values ​​of thermal power prescribed in the regulations and affecting the installation conditions of 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, 0.2 m3 is added to this volume for each kW of water heating equipment. If the total indicator of all units exceeds 150 kW, then the dimensions of the room are not standardized. But there are rules for the installation and safe operation of boilers, according to which it is necessary to withstand the technological gaps between the units and the walls of the room, they are accepted 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 observed as follows:

• From the protruding part of the gas burner to the wall with front side heat generator - at least 1 m.
• If the operating instructions for the unit say that you need to service it from the side or from the back, then you will have to maintain a passage width of 1.5 m, but when there is no such entry, 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, installation requirements are put forward in the documents for the product from the manufacturer.
• If it is planned to put 2 heat sources in the furnace, then you should not place them opposite each other, since you will have to provide a clearance between the protruding parts of the burners of at least 2 m.
• Nothing should 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 for the installation of gas boilers are imposed. It is only necessary to comply with the volume standard given above, and also ensure air exchange in the amount of 3 times in 1 hour. Additionally, you need to submit supply air for fuel combustion, its consumption for each unit is indicated in technical specifications. This standard applies to all types of boilers.

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

V normative documents it is proposed to arrange ventilation for the boiler in the kitchen with the help of an exhaust shaft and an inlet grate built into the front door. The cross section of this grid is also normalized; its area cannot be less than 0.025 m2. In the same way, it is possible to arrange air exchange in separate furnaces. Submission difficulties fresh air may occur in basements or basements, it is possible that a special supply fan will need to be installed to meet the specifications.

In boiler rooms located on the first, ground floor or in an annex, window openings with a glazing area of ​​at least 0.03 m2 per each cubic meter of room volume are needed. Requirements for the 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 it is necessary to step back from the nearest window or door 1 m horizontally.

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

Boiler installation works

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

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

In order to withstand the technology of installing gas boilers, the dimensions of the foundation in terms of plan should exceed the dimensions of the equipment by 50 mm, and in height it should be made protruding 50-100 mm above the level of the screed. Complete solidification 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 installation diagram of the gas boiler, 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 do not need 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 perforator, a hole is drilled in this place. through hole into which a metal sleeve is inserted.

There are no particular difficulties 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 to the fastening process. Difficulties can arise when installing heavy units, whose power reaches 120 kW, here you can not do without an assistant.

Note. When the wall-mounted boiler is attached to a wall consisting of combustible material, a special bracket must be made to allow a clearance of 45 mm 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.

Lastly, the gas boiler is tied and the chimney is installed. 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 in a house the heating circuit is made of polypropylene pipes, then it is better to use bronze taps and a sump, and plastic pipes connect through threaded adapters. In this regard, the installation of a double-circuit gas boiler is somewhat more difficult, where it will be necessary to lay pipes for hot water supply and correctly connect them to the corresponding pipes.

Chimney Requirements

In essence, the requirements for chimneys of floor and wall-mounted 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 emit combustion products through a traditional chimney with natural draft.
• Units equipped with a closed chamber draw air from the street forcibly, with the help of a fan through a double-walled pipe, which simultaneously serves as a flue (coaxial chimney).

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

Below the tie-in, 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 vanes, and so on. In accordance with the regulations, only a constriction nozzle can be supplied.

Unlike traditional exhaust ducts for combustion products, it is much easier to install a double-walled chimney for heat generators with a closed chamber. Having done in outer wall a hole of the required diameter and having 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 observed is a slight slope towards the exit of smoke. It is done so that the condensate that forms in the air path 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.

Gas is considered the most cost-effective view fuel in terms of economy. Even if a branch of the gas pipeline has not been laid in the holiday village, many owners country houses gas tanks are used, which, from the point of view of efficiency, is most often more profitable than using other types of fuel. In any case, you need to know the rules for connecting a gas boiler in a private house, which strictly regulate all the nuances of installation and operation of equipment.

Can I install the equipment myself?

In short, the installation of a gas boiler in a private house can be carried out by any person, but putting the equipment into operation - acceptance and testing should be carried out by specialists from the gas service, connecting a gas boiler in a private house and operating it without their permission is impossible.

It is most reliable to entrust the installation of gas equipment to qualified representatives of a specialized organization. Only they will be able to perform the necessary work competently, in accordance with the requirements of SNiP, and provide safe operation equipment. In addition, a competent specialist always works under a contract, which indicates who, when and what kind of work was done.

The main types of gas boilers

Manufacturers of gas equipment offer customers different types of heating boilers operating on blue fuel. They are designed for heating any area and by type of installation are divided into floor and wall.

The first of these are powerful, reliable and durable "flagship models" designed for installation in homes with above-average footage. General disadvantage there is only one such model - they will have to equip a separate room.

Wall-mounted gas boilers are an excellent alternative for a small private house: they do not need a separate room - such devices are compact and versatile. In addition, their installation does not impose increased conditions on bearing capacity walls - only a layer of non-combustible material is required between the boiler and the base.

Requirements for the boiler room in the house

If the boiler capacity is more than 30 kW, then it must be installed in a separate room. All information on how to install a gas boiler in a private house is given in the SNiP standards, where there are clear requirements for arranging a boiler room for heating equipment powered by fuel combustion.

You can place the boiler room in the attic, in the basement (basement) or simply in a separate room of the house. In this case, a mandatory requirement is free access to the room, sufficient illumination and the arrangement of a rigid base.

In addition, the installation of a gas boiler in a private house has the following requirements for a boiler room:

volume at least 13.5 m³ for boilers with a capacity of 30-60 kW and over 15 m³ for models with a higher capacity;

convenient access to the equipment.

In one hour ventilation should provide three-time air exchange;

walls and floors are made of non-combustible material;

Important! Heating boilers are located at a distance of at least 0.5 m from combustible surfaces. And partitions meet the fire resistance standard RE1 45, that is, they must resist open fire for 45 minutes.

Requirements for a boiler room in a separate building

The advantages of a separate boiler house are increased security, reduced noise level and the possibility of using the vacated area for other purposes. The disadvantage will be an increase in the cost of the heating system device, since it will be necessary to pull an additional heat-insulated pipeline branch.

At the same time, such requirements for such boilers are the following:

separate foundation;

concreted base for the boiler;

forced ventilation, which should provide three air exchanges for an hour;

meeting the requirements for sizes boiler room;

installation is allowed in one room no more than two heating devices;

doors to the street should open outward;

wall surfaces and ceilings are made of non-combustible material;

Availability windows with transom for daylight and emergency ventilation - the area of ​​\u200b\u200bthe window opening should be suitable for the volume of the room (0.03 m 2 per 1 m³);

Availability chimney if it is needed for the installed device (for wall-mounted devices with a capacity of less than 30 kW, it is allowed to lead the coaxial pipe through the wall).

Also connected to the boiler sewage pipe so that water can be drained from the system when it is replaced.

Basic requirements for chimney and ventilation ducts

The room where the gas boiler is located must meet the necessary requirements, while not only the width and length of the room are regulated according to the power of the equipment, but also the size to the ceiling, which must be at least 2 m.

In the boiler room, it is mandatory to install ventilation duct, for this a hole with a cross section of at least 0.02 m 2 is provided.

The location of gas boilers is related to the installation conditions of the chimney. At the same time, the parameters of the latter (height, channel area) relative to the installed gas equipment must be strictly observed.

The size of the internal section of the smoke outlet pipe is made the same or slightly larger than that of the device. According to NPB-98, inside the chimney opening, the air flow speed should be 15-20 m / s, and such draft can be provided with a chimney pipe height of about 5 meters.

Important! Smoke must not be discharged into the duct provided for ventilation. In boiler rooms that have a standard exhaust, air exchange must take place due to the incoming flow from outside the room and, in part, as a result of its penetration from adjacent rooms.

Gas appliance in a private house: requirements and basic installation steps

For proper installation of the unit, you first need to study the regulatory documentation and the rules for performing these works. They talk about the features of installing gas appliances for the installation of a heating system.

What type of boiler would not have to be installed, it is imperative to comply with the requirements of certain norms and rules, such as:

SNiP 41-01-2003 on heating, ventilation and air conditioning.

SNiP 42-01-2002 about the gas distribution system.

SNiP 21-01-97 about fire safety.

SNiP 2.04.08-87 about the arrangement of boiler rooms.

The provisions of SNiP contain all the necessary information for the installation and start-up of a gas boiler. Source optolov.ru

With regard to these conditions, in order to install a gas boiler in a house, you must first obtain a regulatory act that gives permission to carry out work on connecting gas appliances. And in order to purchase technical specifications, it is necessary to submit an application to the local gas service, which must be answered within a month.

It's important to know! Specifications- this is an official permission to carry out work on the installation of a gas appliance. Unauthorized installation of a gas heater without specifications is illegal and unsafe for the homeowner.

Boiler installation

After the development of project documentation and receipt of an act with permission to install a gas boiler, it is installed, which is carried out in several stages:

Preparing a solid foundation. A concrete screed is poured onto the floor, or a sheet of metal is placed. The boiler must be installed strictly parallel to the floor.

Chimney connection and traction test.

Accession heating system pipes. The filter must be installed. fine cleaning, which is usually placed in the return pipe in front of the boiler. And on both sides of the filter element put ball valves.

When installing a double-circuit gas boiler in a private house, it is necessary connect it to the plumbing. It is desirable to insert the supply pipe from above, and the outgoing line - from below.

Connection to the gas pipeline. This can only be done by a gas service specialist.

The installation of a gas boiler is clearly shown in the video:

On this the most necessary work completed. Boilers with a closed combustion chamber are an exception. These devices are equipped electronic control, and their launch is carried out simultaneously with the filling of the system, since without creating a certain pressure in expansion tank the boiler will not work.

Operating rules

For the safe use of gas, the connection scheme for a gas boiler in a private house must be observed. In addition, the following must be conditions:

Perstart operation of the boiler only at normal humidity.

Control technical condition gas service specialists at least once a year.

Filter installation fine cleaning on the return pipeline of the heating system.

natural or artificial ventilation in the boiler room.

Conformity thrust in the chimney pipe requirements (10-20 m/s).

In the event of a leak, notify the emergency gas service promptly.

Maintenance

Preventive measures for routine inspection of gas boilers include the following types of jobs:

Faucet testing external and internal gas pipeline (disassembly, lubrication).

Inspection of thermostats on floor boilers.

Flushing or replacement filter elements.

Injector revision, checking the tightness of the door, the operation of the igniter on floor-standing appliances.

Traction control in the chimney.

Check in winter time ice at the coaxial pipe of wall-mounted boilers.

All components that have been worn out during operation must be replaced.

On a note! After the repair is completed and before starting the heating system, the gas service worker checks the tightness of all connections in the line. Usually a soapy solution is used for this.

A competent preventive inspection will not only increase the life of the equipment in operation, but also reduce gas consumption.

Conclusion

At first glance, the installation of gas boilers in a private house is not the most difficult, the requirements for compliance with standards and safety are high. Installation of a heating system with a gas boiler requires knowledge of the relevant rules and regulations, and the final check and connection should be carried out exclusively by gas service specialists. Trust the professionals and then the gas boiler will serve you faithfully and provide warmth and comfort in your home.
