Wall-mounted gas boiler installation. Installation of gas heating boilers. Ventilation and chimney installation
The task is not easy. The boiler cannot be hung haphazardly, since the safety of the people living in the house often depends on how correctly the wall-mounted boiler is installed.
This means that the installation of this device is carried out in strict accordance with 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 labor-intensive and difficult process for a beginner.
Stages of preparation for boiler installation
Before the owner of the house starts, you will need to collect some documents:
- agreement on supplying the house with gas;
- technical specifications and installation diagram gas system, approved by the relevant authorities;
- written permission from the gas inspector to install the 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.
- The question of how to install a wall-mounted boiler begins with preparing the 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 toilets. However, when installing wall units, this requirement may be relaxed depending on the type of boiler. The volume of the room is from four square meters, the ceiling height is from two meters. The width of the doorway is at least 800 mm. Also in the room there should be natural lighting of the boiler through the window. In this case, the window size must correspond to 0.3 square meters. for every 10 sq.m. premises.
- Rules for installing wall gas boiler regulate the receipt of a certain volume fresh air using fresh air ventilation to the place where the boiler is used. An insufficient amount of incoming air may be due to the accumulation of a substance hazardous to health and life in the room.
- : the standards for its placement are such that there must be more than 10 cm from the wall to the surface of the boiler. If this distance is less than required, the wall must be protected with a fire-resistant coating.
- Gas pipes can be metal, but not plastic.
- The chimney opening must correspond to the power capabilities of the boiler. In this case, 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.
- When organizing a power supply system, it is necessary to provide for the presence of a machine with current protection and with thermal protection.
- In the room where the boiler will be located, there must be a gas sensor connected to a relay. In the event of a gas leak, the sensor must send a relay signal to block gas flow. In addition, an audible alarm should sound.
- Installation of a wall-mounted gas boiler; when starting it, regulations require that the device be provided with a gas meter.
- If there are other gas appliances near the boiler, then the distance between the appliances is set at at least 20 centimeters.
- When installing, the requirements even affect the completeness of the equipment. The boiler package must comply with the standards and contain: a manual, fasteners, a paper template for installation, special keys and fasteners.
- 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 system. gas heating. Please keep in mind that the heating system must be checked regularly maintenance by employees of the city gas service.

Choosing to stay private house, the owners solve several problems at once and free themselves from the need to put up with the difficulties that plague the inhabitants of city apartments. To reach high level autonomy and provide the house with an independent source of heating, homeowners install a gas boiler in a private house in accordance with the requirements of the heating scheme. The device creates comfortable temperature conditions in the house and allows residents to enjoy a cozy atmosphere even in the coldest winters.
Correct installation of a floor-standing gas boiler or a wall-mounted equivalent provides users with the following benefits:
Direct installation of a wall-mounted gas boiler in a private house is a responsible and labor-intensive process. It requires knowledge in the field of heating engineering, and also involves the use of special equipment and a whole list of auxiliary fittings. Since the device burns natural gas in the process of heating water into heat exchangers, certain rules must be followed during installation that will reduce the risk of accidents and provide the opportunity for a long time use a safe and reliable heating source.
Before you start active phase work, it is necessary to study the standards for installing a gas boiler in a private house, and also coordinate actions with representatives of the relevant utility offices.
The property owner must have the following papers in his hands:
The basic rules for installing a gas boiler in a private house are: general character. They require a number of preparatory actions on the part of the user. He will need to optimize the system and prepare it for installation.
To do this you need to do the following:
Choosing a location for installing the device in the house
Unlike apartment residents, who face some problems when installing a heater, owners of private houses have much greater freedom of action. For example, installation of a gas boiler in a private house, the requirements of which prohibit installation of the device in living rooms and bathrooms, can be produced in the furnace (boiler room). If a special room is not provided for by the design of a private house, then the owner can independently determine the place for drilling the brackets and mounting the wall-mounted boiler.
The current standards for installing a gas boiler in a private house, adopted on state level, allow the installation of a heater in the following rooms, which can be converted into a furnace room:
Requirements for room space and its layout may change, so each project is developed individually.
If the wall-mounted gas heating boiler has a sealed combustion chamber closed type, then it can be placed in a room of any size.
If the technical conditions for installing a gas boiler in a private house stipulate the location of the device in the room certain area and require windows, then the owner will have to re-equip the house in accordance with the requirements of the project.
The distance from the wall to the boiler can be from 3 mm to 4.5 cm. The choice of the exact location depends on the boiler model and the design features of the wall. Thus, the choice of location has many nuances, so the owner will not only have to find out how much it costs to install a gas boiler in the house, but also provide for all the features of its placement in the furnace room.
Installation of the device
As you can see, before installing a gas boiler in a private house, the property owner has to do a fairly large amount of work. During its implementation, an approved scheme for installing a gas boiler in a private house will be required, regulating all further actions on the part of the installers.
Home distinctive feature wall heaters are their compact dimensions.
If a regular floor-standing boiler needs to be installed on a special pad and at the same time care must be taken to allocate a sufficient amount of free space around the device, then a wall-mounted analogue can be installed above other household devices.
The main thing is to comply with some requirements. One of them stipulates the features of hanging the device - it is important that there is at least 200 mm of free space from the outer walls of the boiler body to other devices and interior items. In this case, there should be no flammable objects, doorways or windows nearby. You should also prepare a power source in advance - the outlet should be located near the heater, otherwise the owner will have to use a carrier.
When the installation location of the boiler has been approved, the owner must check the equipment included. IN standard version it is represented by the following elements:
Before gas boilers are installed in a private home, the price of which is approximately from 5 to 15 thousand rubles, the owner will have to flush all the tubes and hoses that became clogged during assembly and transportation of the boiler.
When starting in a private house, the price of which depends on many factors, it is important to choose the right height for drilling the brackets. It is recommended to raise the boiler from the floor to a height of 80 to 160 cm. When the slats are installed on the wall, the boiler is hung on them. The device cannot be skewed, so you need to take building level or laser pointer, and make sure that the boiler is hung level.
Next comes the connection of the pipelines to the corresponding boiler pipes. It is advisable to install a filter equipped with shut-off valves. You should also connect the pipeline to the boiler. You should definitely use a paronite gasket for this.
Direct start-up of the boiler is carried out by representatives of special services, who will verify the correct installation of the device and give the go-ahead for its full use.
Installation cost
Homeowners who are planning to sell autonomous system heating, I am often interested in the cost of installing a gas boiler in a private house, carried out by employees of certified companies. Their services are used by clients who do not have the time or skills to self-connection boiler
It is worth noting that the cost of services depends on various factors:
On average, installing a double-circuit gas boiler in a private house will cost the owners real estate in the amount of about 5000-6000 rubles. Specialists can install a single-circuit boiler for a slightly smaller amount.
Additional funds may be charged for project preparation, custom production brackets and grooves, laying pipes, piping the comb (manifold), etc. The presence in the house will lead to an increase in the cost of installation non-standard walls, the thickness of which does not allow the use of conventional equipment for drilling holes and requires powerful equipment.
Choosing a good, powerful boiler for your home is a difficult task for the homeowner. But proper installation of the device is of great importance and is no less responsible. By following the rules for installing heaters in private homes, the owner implements a reliable and effective system heating system that will work properly throughout its entire service life.
For heating a private house the best option, of course, is a gas boiler. This heating unit has high efficiency and allows you to quite smoothly and flexibly regulate the intensity of heating of residential premises, sometimes even without the use of additional thermostatic devices. Today, gas is considered the most profitable fuel in terms of efficiency, so the cost of such a boiler will quickly pay for its purchase and installation costs.
If you plan to install a gas boiler in a private house, the requirements for the premises and the heating device needs to be clarified in advance. Having received general information, you can be sure that you have to collect a lot of different documents and go through several authorities. Therefore, it is worth preparing not only theoretically and technically, but even psychologically for these rather unpleasant, but, alas, necessary events.
Sequence of preparatory activities
Basic regulatory documentation for boiler installation
All this data can be found in SNiP (Building Norms and Rules) 02/31/2001, “Gas supply country house. Requirements and rules for installing gas equipment.”
In addition to this document, you need to review additional ones containing information on the arrangement of boiler rooms and the rules for installing the boiler. They can also be found in the “Building Codes and Regulations”:
- SNiP 41-01-2003 “Heating, ventilation and air conditioning”.
- SNiP 21-01-97 " Fire safety buildings and structures."
- SNiP 2.04.01-85 “Internal water supply and sewerage of buildings.”
To install a boiler room in a private house, you should study SNiP 2.04.08-87.
How is a boiler room equipped in a private house?
IN own home for heating equipment is usually allocated separate room. What requirements must the boiler room meet? – detailed information about this is presented in a separate publication on our portal.
Coordination of gas boiler installation
In order to install a gas boiler in a private house or apartment, it will not be enough to study the SNiP documents. First you need to obtain technical conditions that will become the basis for organizing further work for connecting equipment to gas mains.
To do this, the home owner submits an application to the local gas supply service, which indicates the estimated gas consumption required for use in a particular building for heating and other needs. This parameter is calculated approximately on the basis of SNiP 31-02 standards, clause 9.1.3, which provides the average daily gas volume for a single-family house:
— gas stove(cooking) – 0.5 m³/day;
- hot water supply, that is, the use of running water gas water heater() - 0.5 m³/day;
- heating using a household gas unit with a connected water circuit (for central Russia) - from 7 to 12 m³/day.
IN local organization, which controls gas supply and installation of boiler equipment, the request is reviewed by specialists. A document with technical conditions or with a reasoned refusal is drawn up for the applicant. The review process can take from one week to a month, depending on the efficiency of the control service.
If the request is satisfied, then technical conditions are issued, which must be fully implemented when installing gas equipment. This document will simultaneously serve as a permit to carry out the relevant work.
You need to know for sure that installing gas equipment without obtaining technical specifications is illegal. Moreover, it is inconsistent self-installation boiler - very unsafe, especially in cases where such work will be carried out in multi-storey building. Unfortunately, there are plenty of sad examples of this.
Installation project development
Once the technical specifications are received, you can proceed to drawing up the installation project.
The project is developed taking into account all the requirements specified in the technical specifications. This also includes a wiring diagram. gas communications: for a private house - along the site to the entrance to the residential building, indicating this point in the drawing, and for an apartment - from the entrance to the gas supply pipe to the connection point to the heating boiler
The development of the project should be carried out only by design specialists who have a license to carry out work of this type. As a rule, an organization engaged in gas supply in a particular region (settlement) has a design department, where all such surveys, calculations and their graphic design are carried out.
Project approval
Next, finished project is sent for approval to the branch of the organization that controls the gas supply of the house where it will be installed. The period for approval of the submitted documents depends on the complexity of the project design, and can take from one week to three months.
The following documents with the characteristics of the boiler equipment must be attached to the boiler installation and gas mains project submitted for approval:
- Technical data sheet of the gas boiler.
- Instructions for its use.
- Certificates of compliance with technical and sanitary requirements.
- Examination data on the compliance of this unit with all applicable safety requirements.
These documents are issued to the buyer by the seller along with the boiler, and they are issued by the boiler equipment manufacturer.
If the project has not received approval, then in addition to a reasoned refusal, the applicant is given a list of actions that must be performed to obtain a positive conclusion.

If the project is approved, it is certified accordingly, which means that it is already possible to produce practical work for installation of gas heating equipment.
Basic requirements for the boiler room
A separate room must be provided for the installation of gas equipment with a power of 30 kW or more. It must comply with all existing standards and regulations. Quite often, for a boiler room, they try to choose one of the rooms in the basement or ground floor, but you need to know that such installation of a gas boiler is allowed only for single-apartment private residential buildings.
In a private house, a boiler of any power can be installed, since it is usually placed in a room attached to the house, thus having the opportunity to heat not only living quarters, but also utility rooms.
General requirements
The basic requirements for the boiler room are as follows:
- The area of the room for installing one boiler must be at least 4 m². In this case, the total number of boilers in one room can never be more than two.
- The ceiling height of the room is not less than 2200÷2500 mm.
- A window that is mandatory in a boiler room for natural light, should have a size based on 0.3 m² of window area for every 10 m³ of room volume, but in any case not less than 0.5 m².
- The width of the door opening must be at least 800 mm.
- The distance between the front door and the boiler cannot be less than 1000 mm, but it is better if this interval is 1300÷1500 mm.
- In order to be able to carry out maintenance and repair work, the necessary free space must be provided in front of the boiler, which must be at least 1300 mm.
- The boiler must be installed stably and in a strictly horizontal position - this will minimize possible vibrations and noise.
- The floor in the boiler room must be made of non-combustible material and be perfectly level.
- The walls must also be made of non-combustible materials, and the surfaces near the walls of the boiler can be additionally insulated with heat-resistant materials.
- The boiler room must be supplied cold water. The floor of the room must be equipped with a system for draining the coolant into the sewer system.
- Electrical sockets must have a grounding circuit, since some elements of the boiler, for example, the ignition or the pump, are connected to the electrical supply.
- It is necessary to provide access to the chimney - in particular to the inspection window - to control the patency of the channel and the possibility of cleaning.
Ventilation and chimney systems
Ventilation and exhaust systems for gas combustion products in the boiler room must be installed in compliance with the rules for installing gas equipment, since malfunction or ineffective operation of these systems can lead to either inoperability of the equipment, or, even worse, to an emergency and even explosive situation.
Prices for chimneys and pipes
chimneys
To ventilation and chimney regulatory documents the following requirements apply:
- Ventilation and chimney ducts must be separated.
- To allow fresh air to enter the boiler room, it is necessary to provide supply ventilation. The entrance window is made at the bottom outer wall or front door. The size of the ventilation window must be no less than 1/30 of the total area of the room, but no less than 80 mm² per 1 kW of installed power - for air inflow from the street, and no less than 300 mm² per 1 kW, if the influx air flows from another room.
- The ventilation ducts must always be open, as air must circulate constantly.
- It is recommended to install the boiler as close to the chimney as possible.
- A chimney installed in a wall must have two inlet channels:
— the main one, for installation of the chimney pipe;
- inspection channel, located no less than 250 mm below the first one - this channel is intended for technological cleaning.
- The exhaust vent of the chimney should not have a cross-section smaller than the outlet pipe of the boiler itself.
- The chimney should not have more than three bends or turns.
- The chimney pipe is made of stainless or carbon sheet steel. The use of asbestos concrete pipes or others made of layered materials is permissible only at a distance of at least 500 mm from the boiler chimney pipe.
- In order for the operation of the boiler to be safe and the heating system itself to be effective, it must be created favorable conditions to maintain normal traction. Therefore, it is very important to calculate and overall height chimney pipe, and its location above the roof surface, so that the head does not fall into the zone of the so-called wind support.
A house, by definition, should be warm. There are many ways to make it this way. However, every owner strives to do this in the most economical and practical way. One such option is installing a gas boiler. Gas heating is profitable and quite simple to install and operate. Connecting devices should only be carried out by specialists, but arrangement of the boiler room, installation of the boiler, etc. You can do it yourself, saving a decent amount.
Installation of gas equipment should begin with obtaining permitting documents and necessary approvals. It is necessary to order a project for gasification of premises and installation of gas equipment. The document is developed and approved by specialists from the gas supply company. Once you get acquainted with the project, you can start purchasing necessary equipment, the main characteristics of which must be present in the document. In addition, an agreement on the submission of natural gas. After this, you can directly install the system.
We will equip a suitable room for the boiler
Gas boiler – main element heating system. To install it, you will need to properly equip the room. It must comply with a number of strict requirements, violation of which entails significant penalties and provokes accidents with the most severe consequences. Gas is an explosive and flammable substance. You need to be extremely careful with him.
The room in which it is installed gas equipment, must meet a number of requirements. The main characteristics of the boiler room are presented in the form of a diagram
When choosing a place to install a heating gas boiler, you need to take into account the following requirements for the room:
- a channel must be equipped in one of the walls to remove combustion products;
- mandatory presence of natural light. The minimum window area is calculated using the formula: cubic meter room volume – 0.03 sq. meters of window surface;
- ceiling height at least 2.5 m;
- layout providing unobstructed access to the boiler and auxiliary equipment;
- availability ventilation grille located in the lower half of the wall or door. The area of the structure is calculated based on the ratio of 8 square meters. cm grates for every 1 kW of boiler;
- volume – minimum 15 sq. m;
- fire resistance wall structures– at least 0.75 hours;
- the presence of a gas analyzer and an automatic valve that responds to its signals, which will shut off the fuel supply in the event of a gas leak;
- a well-organized chimney, the cross-section of which must correspond to the power of the equipment;
- The door width should not be less than 80 cm.
It must be remembered that the installation of gas boilers with a power of less than 60 kW is permitted in any room except those intended for residential use. It is also not recommended to install gas equipment in a bathroom or toilet. Double-circuit appliances are prohibited from being installed in kitchens. If the total power of the equipment is not higher than 150 kW, it can be installed on any floor of the building. Devices of higher power can only be located on the ground floor or in the basement.
Many people prefer to place gas equipment in the kitchen. In this case, the standards regulating the installation of gas boilers require calculating the required minimum area based on the requirement that per 1 kW of power there is at least 0.2 m 2 of room. If the kitchen is combined with the living room, it becomes mandatory to have a gas analyzer that can detect a possible gas leak in time.
If the boiler power allows, gas equipment is often installed in the kitchen, even if it is a shared room with the living room. In this case, the presence of a gas analyzer becomes a mandatory precaution.
Gas equipment installation technology
In order for the installation of the boiler to proceed without complications, you should pay attention to the method of its fastening even when purchasing the equipment. You should check the equipment of the device and find out the presence of fasteners. If they are not available, you must immediately buy suitable ones. In addition, when purchasing equipment, be sure to check whether it has a certificate. If the document is missing, serious problems with registration may occur. The characteristics of the device and the serial number printed on the inner door of the device must match the information specified in the passport.
Option #1 - installing a floor-standing boiler
Before you install floor-standing device a place should be prepared for it. Let's start with the floor. Since the equipment is heavy, the base must be strong. You may need to fill the screed. The floor on which the boiler will be installed must be made of material with a fireproof coating. If this is not the case, hollow concrete blocks 100 mm high and covered on top with a sheet of metal 0.8 mm thick. As an option, you can consider using fireproof boards approved for such purposes.
The device must be placed at a distance of at least 0.1 m from the wall, provided that the coating is made of non-combustible materials. If it is necessary to move the device close, the wall must be fireproof. In this case, the base is insulated with roofing steel, which is applied to an asbestos sheet with a thickness of at least 0.3 cm. The insulation must overlap the perimeter dimensions of the device body by at least 0.1 m. All protruding parts of the boiler fittings or gas burners must be at least 1 m away from the walls.
The equipment is installed on the prepared base as level as possible. A building level is used for checking. If necessary, place solid non-combustible material under the legs of the device. The boiler is connected to the chimney and internal heating system. To prevent rapid clogging of the heat exchanger, a hard cleaning filter is installed in front of the return inlet. If the boiler is double-circuit, a connection is made to a pipeline with cold water.
A floor-standing gas boiler must be installed on a prepared base. If necessary, the floor is reinforced and a base made of non-combustible materials is installed. Most often these are hollow concrete blocks 100 mm high, covered with a sheet of metal
Experts recommend installing the boiler so that it can be easily dismantled. Shut-off valves are installed on all pipes connected to the device. They will make it possible, if necessary, to dismantle the equipment without unwanted discharge of water from the operating system.
You need to remember that with your own hands complete installation gas boilers cannot be produced. A certified specialist must be invited to check the correctness of the installation, perform the remaining necessary measures and start the system.
Option #2 - connecting attachments
Proper installation of gas wall-mounted boilers begins with flushing the internal tubes. During assembly, various small debris could easily have gotten into them and needed to be removed. To do this, remove the plugs necessary for transportation from the device and pass water through it under slight pressure. After washing, the equipment is ready for installation.
The wall where the device is planned to be mounted must be very level and strong enough to support the boiler and related devices. If the base is made of flammable materials, a non-flammable gasket with a width of at least 3 mm is attached to it. In this case, the boiler is fixed at a distance of at least 4.5 cm from the wall. Installed device must be kept at least 20 cm away from other equipment or flammable materials. It is not recommended to place the boiler close to a window or in a small wall opening. The power source must be located close to the device.
The device is mounted on strips that are mounted on the wall at the desired height. Typically it is located between 0.8 and 1.6 meters from the floor. After securing the device using a level, check the horizontal installation. All identified inconsistencies are corrected, otherwise this may negatively affect the operation of the equipment. Connection to water supply is being made. Before doing this, be sure to remove the plugs from the pipes. It is advisable to install filters at the water inlets, so the heat exchanger will become less clogged.
A wall-mounted gas boiler must be installed exactly horizontally; the accuracy of installation must be checked with a level. Otherwise, problems with the operation of the equipment may occur, even leading to emergency situations.
The gas pipeline is connected to the boiler only using metal pipe rigid connection or through a special drive. A paronite gasket is required. Direct connection of the system is carried out only by certified specialists who will check whether the boiler is installed correctly and start the equipment.
Gas heating is efficient and economical. However, do not forget that gas is potentially dangerous. No need to try to install it yourself gas appliances without special knowledge and skills. The cost of a mistake can be too high. Regardless of who installed the equipment, the connection is carried out only by gas company specialists. They also check the correctness of the installation. You should not save money on the services of professionals. Even though it may seem that the cost of their work is too high, believe me, the life and safety of everyone living in the house is worth much more.
