Today, gas can be called the best source for residential heating. The boiler is also an integral part. Its efficiency is high, while it does not require large maintenance costs. Everyone will be able to regulate the supply of heat in the room. But before you install a gas boiler, you need to create suitable conditions and take into account the requirements. This is what we will talk about in our today's article.
Documentation and boiler preparation
There are special rules for installing equipment in a house, cottage or country house. The necessary information can be obtained by examining the available regulatory documents. In order for the autonomous heating system to start working, it is worth considering every step during installation. When studying the laws on the installation and operation of gas equipment, you need to understand that if you do not follow the rules, you will be denied gas supply.
There is a whole list of documents:
- SNiP 41-01-2003 on ventilation, heating and air conditioning.
- SNiP 2.04.01-85 on the arrangement of internal water supply.
- SNiP 21-01-97 on fire safety.
- SNiP 2.04.08-87 on the arrangement of the boiler room.
Just because no one can connect to the central gas supply. To do this, you will have to collect the required documents and obtain permission. The installation of a gas boiler in a private house should take place sequentially. The first step to obtain specifications is to visit the local gas service. You also need to write an application for the rate of expenditure on residential premises. At the same time, there are average indicators for Russia.
As soon as the application is received, it is considered by specialists. After that, technical specifications are officially issued (where all the norms for installing a gas boiler are indicated) or they are refused, determining the reason. According to the rules, there is time (about 30 days) for consideration of such an application. But if necessary, this time can be reduced. It should be noted that without technical conditions it is impossible to connect equipment. This is against the law, and also entails accidents and danger to humans.
Once the first step is completed and the documents are in hand, it's time to make a project to install a gas boiler and connect. What it is? In a schematic view, a complete picture is drawn of how the installation will be carried out. It all starts from the main highway. The laying of pipes, the place of entry into the house and through the room itself to the boiler are also taken into account.
Again - no amateur performances! They do itaccredited professionals. Having received such a project, you need to pay some money. Usually it is three thousand rubles. Further, this project is given to the gas section at the place of residence for approval. To get an answer, the necessary signatures and seals on the project, you will have to wait 90 days. Such work begins on a personal request.
In addition, the package must be supplemented with the following documents:
- The registration certificate and other documents for the boiler that will be in the house.
- Certificates.
- Confirmation that the boiler is fully functional and safe.
Sometimes a rejection comes along with a full description of the reason. In addition, there are recommendations on what needs to be done so that gas appears in the house. It is important to understand that the collection of documents is a complex process that requires money, time and patience. Without this, no one has the right to introduce gas into a residential building and allow them to heat.
What should the room look like? Requirements
The installation of a gas boiler in a private house must be carried out in a specific and permissible place. But the site may be different, since each unit has its own power rating. If it is up to 30 kW, then it can be located anywhere. After this figure, you will have to organize a special room. The boiler room is the place for all the equipment. In any private house there are cellars, storerooms, a veranda, etc. It is there that you can arrange, according to the requirements, a place for heating equipment and units. Sometimes you need to add a new room to organize everything according to the rules.
How the boiler room should look like:
- The area of such a room is not less than four square meters, and the boiler - no more than two.
- Ceilings - more than two meters.
- At least one window is required.
- Door - with an opening of at least 75 centimeters.
- The boiler must stand at least one and a half meters from the entrance.
- In order to easily carry out repairs and maintenance of the unit, there is also a distance in front of it.
This equipment is mainly placed horizontally to reduce noise and vibration flows. Before placing it, the floor is leveled and a protective sheet is laid. Please note that it must be made of non-combustible materials. It is recommended to protect the walls in the boiler room with compounds with low flammability. It is these conditions that must be created before submitting documents and carrying out a full-fledged installation of heating equipment.
Next, a specialist from the gas department comes and checks everything, based on requirements. You will also have to make an extract in accordance with the norms and requirements. There are additional recommendations. This is the presence of cold water in the boiler room. Before the installation of a gas boiler in the house is completed, everyone performs such preparation.
Chimney and ventilation
It is clear that we will have to make a ventilation pipe and an exit for smoke. This is necessary not only according to the rules, but also in order for the equipment to function fully. Both additional outputs are mounted separately from each other. Ventilationnot only removes smoke, but also makes it possible to fill the room with oxygen. Sometimes they make a design with injection.
You can make such a hole both in the wall and on the door. The specific site and place depend on the boiler room itself and its capabilities. Before making such a hole, you need to know the minimum allowable dimensions. It also takes into account where the vent goes (to the next room or to the street). This distance is never closed so that the air can fully enter and exit.
The choice of the chimney must be made so that the boiler is next to it. Most often, he has two main channels:
- Basic - pipe installation.
- Auditor - service. It runs below the first one.
The hole is sawn in accordance with the nozzle of the gas equipment. In addition, it is necessary to perform it in such a way that turns and bends are fixed. What is this structure made of? Do not give preference to materials of low strength. It is better to make a stainless steel structure. Installation of a gas boiler in a house cannot be done without a branch structure - a chimney.
Since the conditions must be met, calculations and material selection are made before installation. This will help to take into account the rules and emphasize the safety of the design for people. In addition, the pipe has its own characteristics, so any option is not suitable:
- The distance above the roof is at least half a meter, provided there is no ridge.
- If such conditions failcreate, then the head is additionally fixed, which is 50 centimeters higher.
- If the roof is pitched, then the pipe should extend 150 centimeters from the ridge. The headband is also fixed.
When ventilation and a chimney are created independently, it is worth adhering to the regulations, otherwise they may not supply gas to the house.
Many today have a gas boiler in the kitchen, which is very convenient. But this room also has basic requirements:
- The volume of the room is at least 15 cubic meters.
- Ceilings must be at least two and a half meters high.
- A hood is required.
- There must be at least one window with a window in the room.
- When installing a floor gas boiler, ventilation is done in the door. It is needed for the outflow of combustion products in the event of a leak.
Without creating such conditions, gas equipment will not be allowed to connect. There are rules that are not fixed in the regulations, but sometimes they are required to be followed. It is the presence of a door. Some cannot change the existing interior, but otherwise the permit will not be signed. Before the installation of a gas boiler in a private house is completed, the premises are accepted and an act is signed, so that any violations are unacceptable.
It is believed that the connection process takes place according to regulatory documents. Employees of the gas section or accredited persons and organizations always participate in the work. Today there are enough such people. They know the rules and regulations for installing a gas boiler. Of course, this type of serviceavailable for a fee.
How to connect the boiler?
Going for the device itself, you need to understand that the choice is huge. It is based not only on personal preferences, but also on the requirements for the area of \u200b\u200bthe living space. They are divided most often by characteristics. Therefore, before choosing, you should know:
- Method of installation of equipment.
- What design is relevant and convenient.
- How much power is required per square meter of a house.
- How the igniter is ignited.
- Methods for removing combustion products and forcing oxygen.
There are single and double circuit units in stores. They have their own characteristics and features of operation. If this is the first option, then it is used only to supply heat to the house. If you want to have warm water, then this is the installation of additional equipment. The double-circuit design is the injection of heat into the house, as well as heating the water to the desired temperature. There is also a separation of the water supply. This is a flow system or a built-in boiler. A boiler with a double-circuit device is in demand more often, but its cost is also higher.
Types, power
Also, units are divided by location. Distinguish:
- wall-mounted boilers;
- floor units.
In terms of dimensions, outdoor devices are larger than their predecessors, so sometimes a special boiler room is made for them. But the wall began to be in demandmore often because of its neatness and small size. They are suitable for operation not only in private houses, but also in apartments of multi-storey buildings. They have a big plus - the lack of a full-fledged chimney. Since the coaxial removal of combustion products is performed, it is made in the wall.
In order for the work to be carried out fully, and there was enough heat supply, you need to correctly calculate the power of the device. Otherwise, the heat supply to the room will be incorrect. On average, ten square meters need at least 1 kW of the boiler power indicator. Do not forget about a small margin of five to seven percent, otherwise the equipment will operate at maximum strength, which can provoke rapid wear.
When calculating, do not forget about the temperature indicators of each region separately. In warm places, 1 kW is enough, but for the north you need to bring this figure to two. Therefore, the installation of a gas boiler in a private house should be carried out taking into account the requirements, as well as weather indicators throughout the year. Otherwise, it may happen that the room will always be cold.
What's next?
When the work and collection of documents are completed, you need to go to the gas industry to invite specialists for control. Some create conditions on their own - a boiler room, a place for a boiler, protective structures, etc. This saves time and money. It is believed that it is more difficult to install a gas boiler in an apartment, especially if the floor is not the first. Large footage of pipelines will be required, and these are additional costs.
Representatives in the gas industry will recommend that the work be carried out by a team of specialists with experience and knowledge. Today there are such representatives in the official Gazprom company, as well as individuals who have received accreditation. They have access to an official company, provide the necessary documents. Because today the state compensates part of the cost of installing and connecting gas equipment to certain groups of people.
Compliance with boiler installation rules
It is important that the entire system is installed safely and securely. This task can be easily and quickly handled by experienced professionals. They will definitely not violate the law, after which the acceptance will be carried out quickly, and the gas supply will be carried out in a short time. When a decision is made on independent work, it is worth first obtaining permission from the regulatory authorities. It is possible to carry out preparatory work, taking into account all regulatory indicators. But the start-up of gas and the testing of the boiler are still carried out by specialists.
The project and technical documentation should always be at hand in order to understand exactly what needs to be purchased. Only after the desired constituent element is obtained, work begins. If this is a floor unit, then the most even surface is prepared for it. This is a cement-sand screed. After that, a galvanized sheet is placed on it. Sometimes you can finish with tiles. In addition, such a surface should be not only under the boiler, but also nearhim. There should be a free distance of at least half a meter in front of him (on the sides - a little less). This data is also duplicated in the documentation.
Installation of a floor gas boiler will be carried out so that it stands firmly on all its legs. The slightest error and staggering is not allowed. In the course of work, it is better to use the building level. Any mistake will result in inconsistent and poor performance of the device.
Distance
Requirements for installing a gas boiler in a house have the following distance indicators:
- From the boiler to the ceiling - at least one and a half meters.
- To the wall, which will not have metal protection - at least half a meter.
- From the chimney to the wall without protection - at least 45 centimeters.
- If the wall is iron structure, keep a distance of about 30 centimeters.
From this it becomes clear what are the requirements for a room for installing a gas boiler.
How to fix the unit on the walls?
The first requirement is the availability of special brackets or retaining bars. They usually come with the device in the package. From the floor, the required footage of one meter or more is observed. A device is used that shows maximum evenness. As soon as the brackets are driven in, the boiler is fixed on them.
This is how a wall-mounted gas boiler is installed. When this is done, you need to connect the equipment and expose it to the chimney. It is worth fixing the pipe as tightly as possible, without errorand with additional sealing. After you can start the water. It is tough, so that the equipment does not fail, you cannot do without a filter. Do not forget about cut-off taps, so that if necessary, you can send the boiler for repair. A prerequisite is complete sealing. It is difficult to do it yourself, so the experience of specialists will be appropriate.
Summing up
Of course, when the main work is done, the premises are selected, you need to make a purchase and installation. The apartments will have to create the most comfortable conditions for this. In a private house, it is better to allocate a special room for this. It is convenient to do this in the kitchen, because there is water, a gas pipeline, an extractor hood and a window nearby (you don’t have to do anything extra). You just need to choose a convenient place and perform installation.
If you choose any other room, it will not fit according to the parameters and the law. Gas heating is by far the best option for everyone, as heat is supplied to a house of any size. There is no smoke and dirt from simple raw materials - firewood and coal. But you need to remember that after installation, the boiler will be checked every year by gas workers for safety and correct operation.
