Connecting heating and plumbing

The second stage is connecting heating and water pipes. Their number depends on how many circuits there are in the boiler. Before installation, do not forget to remove the plugs from the pipes. Filters should be installed on the pipes through which water from the heating main will flow to prevent the system from clogging with dirt or debris.

The quality of the water is important - if it is hard, you will have to install treatment equipment, for example, polyphosphate dispensers.

The boiler pipes are connected to the pipelines using a threaded coupling. For tight fixation, fum tape is used.

Connecting the boiler to gas

Only a gas service specialist or an organization licensed to carry out such work can complete the third stage - connecting the wall-mounted gas boiler to the general mains.

Connecting on your own is illegal and can also lead to an irreparable tragedy. Therefore, first of all, contact the gas service. There, technical connection conditions will be developed specifically for your equipment.

Gasification can be carried out underground and aboveground. For underground pipes, polyethylene pipes are used, which are very resistant to corrosion. The above-ground method involves the use steel pipes, which enter the structure next to the location of the gas boiler at a height of 1.5 m from the floor.

If there are several in the house heating devices, gas is supplied to each of them separately. It is prohibited to lay a highway indoors.

All pipeline connections are sealed using paint or tow. It is necessary to install on the tap gas filter, which protects the boiler from debris and condensation.

Electrical connection

The fourth stage is connecting the unit to electricity. Many modern models wall-mounted gas boilers are equipped with a complex automation system. It allows you to control the operation of the boiler without owner intervention, and also monitors safety.

Double-circuit units are produced in two versions: with a socket and with a cable for connecting to the machine.

If you purchased the unit with with a regular fork, then it should be placed closer to the outlet. According to safety requirements, it should be located next to the boiler, and not under it. This is necessary to avoid a short circuit, which could cause coolant leakage from the device.

The gas unit requires mandatory grounding. To do this, purchase a point grounding kit, which can be located in the basement of the house or next to it.

In order for the automation to serve for a long time and not fail, it is necessary to provide the unit with a stable voltage without significant drops. If this condition is not met, you will have to buy a stabilizer.

First start-up of a gas boiler

The first start-up of a wall-mounted gas unit must be carried out by a specialist. He will set the boiler to a certain mode and check that it is operating correctly.

Before starting, the unit is slowly filled with water until its pressure in the system reaches 2 atmospheres. The tightness of all existing connections is carefully checked. In progress commissioning works You can ask a specialist all your questions about the operation of the heating device.

If the boiler is working correctly and everything is in order, sign certificate of commissioning of the unit.

Most modern private houses have gas boilers. This device can be called affordable, safe and economical, but it belongs to the group of expensive and difficult to install products.

Gas boilers are divided into two groups: single-circuit and double-circuit. The first type is used to heat the room, the second type can simultaneously heat the room and heat water. Therefore, it is important to know the rule of how to install a double-circuit gas boiler in a house. The equipment also differs in power and type of installation.

How to choose a boiler

An important rule for installing a gas boiler in a private home is determining the required power. Low productivity does not allow obtaining the required effect. Too much power is not economically beneficial and is dangerous, since acidic condensate formed as a result of constant temperature changes negatively affects some parts of the device.

To determine the boiler power, it is necessary to divide the area of ​​the house by 10 and multiply by the appropriate coefficient, the value of which depends on the region of residence. For example, for central regions a value of 1.2-1.5 is used, for southern regions– from 0.7 to 0.9, in regions with a predominance of cold – 1.5-2. From this we can conclude that for a house of 120 m2, located in the south of the country, it is enough to purchase an apparatus with a capacity of 8-10 kW.

Using special devices you can change the boiler power value. At the same time, low-capacity devices have a single-stage regulator; middle-class heating devices are characterized by a two-stage regulation, boilers high performance have a modulated regulator.

Gas boilers can be wall-mounted or floor-mounted. Depending on this, the installation of the device has its own subtleties. In addition, the direct installation of gas equipment in a private home requires mandatory compliance with certain rules in accordance with Sanitary Standards and Rules.

In particular we're talking about about the following:

• SNiP 41-01-2003 “Heating, ventilation and air conditioning”.
• SNiP 31-01 from 2003 “Residential and multi-apartment buildings”.
• SNiP 42-01-2002 “Gas distribution systems”.

Rules for installing gas appliances

The following rules for installing a gas boiler are presented for the premises:

• To install the boiler, a separate room is required, which can be located on one of the floors of the house, in the basement or attic. Installation of equipment in residential premises and bathrooms is not allowed.
• The boiler room in which the gas boiler will be installed must have certain dimensions. For example, for boilers with a power of less than 30 kW, which are able to cover all the heating needs of a private house, a room with an area of ​​more than 4 m2 is required. Boilers with a power of over 30 kW, but not more than 60 kW, can be installed in a room with an area of ​​13.5 m2. Equipment with a power exceeding 60 kW requires an area of ​​up to 15 m2. Boilers with a closed combustion chamber can be installed in rooms of any size, starting from the established minimum value.
• The ceilings in the boiler room must be high enough, at least 2.5 meters.
• In a room with gas equipment prerequisite is the presence of a window, 30 cm of which falls on every 10 m2.
• The door to the boiler room must have a width of more than 0.8 meters (read also: “Installation of a gas boiler room in a private house - requirements, standards”).
• A gap of 2.5 cm should be provided between the top level of the door and the main opening.
• Combustible finishing materials must not be used in the boiler room.
• It is prohibited to install a false floor or false ceiling in a room with gas equipment.
• There must be a hole for natural air flow. Moreover, for one unit of boiler power, at least 8 cm 2 holes are required.
• It is necessary to supply water to the boiler room to install a double-circuit gas boiler.
• Maintenance optimal value humidity, since if there is excess moisture in the boiler room, the escape of gas vapor is difficult.
• Installation of ventilation in the upper part of the boiler room. Read also: "".

Parts and pieces of equipment must also comply with the standards for installing a gas boiler in a private house:

• Free access to the device from any side.
• Use only metal gas pipes.
• A gas meter is required.
• Electric boilers require mandatory grounding.
• Parallel installation of a gas analyzer and automatic valve. The first device will give a warning about a possible gas leak, the second will stop the gas supply if a leak is detected.

Chimney requirements

Installation of chimneys or gas outlets must be carried out in compliance with the installation parameters of a gas boiler in a private house:

• Gas combustion products must be discharged through a separate channel.
• The horizontal section of the chimney should be no more than 3 meters.
• The chimney structure cannot have more than 3 elbows.
• For a certain boiler power, a corresponding gas outlet diameter is required.
• The cross-section of the chimney must correspond to the diameter of the hole to which the flue is connected.
• The top point of the chimney should be located 0.5 meters above the level of the ridge.

Most modern boilers with a closed combustion chamber are sold complete with coaxial chimney. Such devices can be installed in a room of any size, since combustion air is taken from the street.

The listed requirements for the installation of gas equipment, including the installation of a double-circuit boiler in a private house, may have additions and clarifications in accordance with the region of use. In addition, the gas supply may not be central, but bottled. Also, the rules may be adjusted depending on the material used to build the house and floors.

Design

All this leads to the fact that before installing a gas boiler, it is better to consult with a specialist who will inspect the structure and identify relevant shortcomings.

To obtain permission to install a gas boiler, you must do the following:

• Write an application in the appropriate form to the organization that supplies gas. This document becomes a kind of permission to carry out preparatory construction work. In most cases, permission is issued no later than two weeks from the date of registration of the application.
• After this, it is necessary to make a project, its production is carried out by licensed specialists.
• The finished project is subject to mandatory approval from the gas supply organization. The full package includes an application, design documentation and documents for gas equipment. Approval may take up to 3 months.

Installation in a private house

Installation of floor and wall equipment is carried out according to different schemes.

The technology for installing a floor-standing boiler includes the following steps:

• Preparing a solid foundation that can withstand the weight of the boiler. Can be filled concrete screed or lay a sheet of galvanized iron.
• Level check installed equipment. The boiler must be positioned strictly parallel to the floor level.
• Connecting to the gas outlet and checking the draft.
• Connecting heating system pipes with mandatory installation hard water filter. In addition, the installation of ball valves on all pipes and shut-off equipment on both sides of the filter is required.
• When installing a double-circuit boiler in a private house, a connection is made to the water supply system. In this case, the supply pipe should be located at the top, the return pipe at the bottom.
• Connection to the gas pipeline. This item can only be carried out by a gas technician, independent work such plans are strictly prohibited.
• Connection to the power supply network.

There are certain rules installation of a wall-mounted gas boiler:

• Choose the strongest wall or partition and protect it with fireproof material.
• Fix the boiler, maintaining a distance from the wall plane of about 5 cm. You should also retreat from other walls and the ceiling by 50 cm, from the floor by 80 cm. The boiler should be located parallel to the floor level.
• Before installation, the walls of the inlet pipes should be cleared of debris by supplying water under pressure.
• Install the filter on the water supply pipe. Install locking mechanisms on both sides of the filter.
• Install a chimney, if provided for by the project, and check the draft.
• Connect the device to the gas pipeline, inviting a gas service technician for this purpose.
• Connect to the power supply.

Both options provide for filling the system with water before starting and first turning off the device. To avoid the formation of air bubbles, water must be introduced into the system very slowly.

In addition, the procedure for installing a gas boiler in a private house provides for temperature restrictions. Installation of a gas stake can be carried out at temperatures from +5 to +35 degrees.

Maintenance of gas boilers during operation

Gas equipment must be checked at least twice a year. Moreover, one of them falls on the period before heating season. Gas service specialists check the tightness of the chimney and its operability, condition ventilation system, perform maintenance and repair work.

Gas is considered the most cost-effective type of fuel in terms of efficiency. Even if there is no gas main line to the holiday village, many owners country houses They use gas tanks, which from an economic point of view is 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 the equipment.

Is it possible to install the equipment yourself?

In short, the installation of a gas boiler in a private house can be carried out by anyone, but commissioning of the equipment - acceptance and testing must 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 safest to entrust the installation of gas equipment to qualified representatives of a specialized organization. Only they can produce necessary work competently, in accordance with the requirements of SNiP, and will provide safe operation equipment. In addition, a competent specialist always works under a contract, which specifies who carried out what work, when and what.

Main types of gas boilers

Manufacturers of gas equipment offer customers different types of heating boilers running on blue fuel. They are designed for heating any area and, according to the type of installation, are divided into floor and wall.

The first of them are powerful, reliable and durable “flagship models”, designed for installation in houses with above-average square footage. There is only one general drawback of such models - they will have to be equipped with a separate room.

Wall-mounted gas boilers serve as excellent alternative option 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 - you just need a layer of non-combustible material between the boiler and the base.

Requirements for the boiler room in the house

If the boiler output 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 the arrangement of 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 separate room Houses. A mandatory requirement in this case is free passage into the room, sufficient illumination and the arrangement of a rigid base.

In addition, installing a gas boiler in a private house requires the following boiler room:

volume not less than 13.5 m³ for boilers with a power of 30-60 kW and over 15 m³ for models with higher productivity;

comfortable access to the equipment.

A properly designed boiler room for a private home Source teploknam.ru

within an hour ventilation should provide threefold air exchange;

walls and ceilings made of non-flammable material;

Important! Heating boilers located at a distance of at least 0.5 m from flammable surfaces. And the partitions comply with the fire resistance standard RE1 45, that is, they must resist open fire within 45 minutes.

Requirements for a boiler room in a separate building

The advantages of a separate boiler room are increased safety, reduced noise levels and the ability to use the freed-up space for other purposes. The disadvantage will be that the heating system will become more expensive, since it will be necessary to install an additional thermally insulated pipeline branch.

At the same time, such requirements to such boiler houses are the following:

separate foundation;

concrete boiler base;

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

fulfillment of requirements regarding sizes boiler room;

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

doors should open outwards to the street;

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

availability transom windows for daylighting and emergency ventilation - the area of ​​the window opening must be suitable for the volume of the room (0.03 m2 per 1 m³);

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

Also connected to the boiler sewer pipe so that water can be drained from the system when replacing it.

Basic requirements for smoke exhaust and ventilation ducts

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

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

The location of gas boilers corresponds to the installation conditions of the chimney. In this case, the parameters of the latter (height, channel area) in relation to the installed gas equipment must be strictly observed.

The size of the internal cross-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/sec, and such draft can be ensured with a chimney pipe height of about 5 meters.

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

Gas appliance in a private home: requirements and main installation steps

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

Whatever type of boiler would have to be installed, it is imperative to comply with the requirements of certain norms and rules, such as:

SNiP 41-01-2003 about 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 installation of boiler rooms.

SNiP provisions contain all the necessary information for installing and starting a gas boiler Source optolov.ru

In relation 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 to purchase specifications, you must submit an application to the local gas service, to which a response must be given within a month.

Important to know! Technical specifications are the official permission to carry out installation work gas appliance. Unauthorized installation 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, its installation is carried out, 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 checking traction.

Accession heating system pipes. In this case, a fine filter must be installed, which is usually placed in the return pipeline in front of the boiler. And on both sides of the filter element there are ball valves.

When installing a double-circuit gas boiler in a private house, it is necessary connect it to the water supply. It is advisable to insert the supply pipe from the top, and the exit pipe from the bottom.

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

Maintenance

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

Checking taps external and internal gas pipelines (disassembly, application of lubricant).

Inspection of thermostats on floor boilers.

Flushing or replacement filter elements.

Injector inspection, checking the tightness of the door, the operation of the igniter on floor-standing devices.

Traction control in the chimney.

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

All components that have been subject to wear during operation must be replaced.

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

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

Conclusion
