Installation of a gas boiler: fulfillment of requirements and approval of documents

After conducting gas supply to a private house, the next task, as a rule, is the installation of gas equipment.

Requirements for installing a gas boiler

Many apartment owners also refuse central heating and prefer an autonomous option to it, wanting to save money and turn on/off space heating when they see fit. But to such heating was safe and efficient, it is necessary to comply with the requirements for installing a gas boiler.

In the organizations controlling gas supply, the necessary documents are drawn up and coordinated and on onleading the gas pipeline to the house, and by installation of heating units.

Boiler Installation Documentation

One of the rather unpleasant procedures when installing a gas-fired heating boiler — This is the collection and execution of a voluminous package of documents. Many, faced with this process, soon rush to abandon this idea.

Before proceeding with the installation, you will have to devote a lot of time to coordination

Main requirements and standards can be found from the document "Gas distribution systems", included in SNiP 42—01—2002. In addition to it, it would be nice to study a document that is no longer working, but contains a large amount of information that will also be useful. — This is gas supply SNiP 2.04.08—87. Extras have to familiarize yourself with the regulations given in related documents describing boiler installations, ventilation system, heating, sewerage, plumbing, safety during construction, sound insulation, fire safety, etc.

Boiler installation approval

You need to go through several instances to get approval for the installation of a gas-fired boiler. Independently, without approvals, the installation process will be illegal and unsafe, and not only for the homeowner, but also for others residents of the house, if boiler installed in high-rise building.

1. Technical terms

For connection to the gas supply of a private house or apartment have to obtain technical conditions from the gas supply organization that allow this procedure. For this, an application is written to the controlling organization. AT German you need to indicate the approximate demand volume hafor for hour. The registration process takes seven - fourteen days. Upon successful completion of this event, a document will be issued — technical conditions for the installation of equipment operating on gas fuel. This is the permit for preparatory construction and installation work.

2. Project

Having the technical conditions in hand, you can proceed to the second step by step - development project documentation. Proekt prgas supply management includes schemes for laying a gas supply pipe from the boiler installation site to the central gas pipeline.

The project will also indicate sections of the gas pipeline crossing the section

If the dwelling is in the private sector, and pipeline must cross the land, then it is compiled more and a diagram of the gas pipe in the area where the location is indicated her entrance to the wall of the house. The project is developed by engineers licensed for such activities, based on the provisions GOS.

3. Coordination with the gas supply organization

Ready proekt dlI agree to transfer to the organization that controls the gas supply in the area of ​​residence of the applicant. Approval of the project takes from seven to one hundred days — it depends on the volume and the complexity of the document. The following materials regarding the heating device are attached to the project:

• boiler conformity examination everyone requirements that are necessary for ensure normal operation and safety;
• technical passportrt prybora;
• certificates of compliance with technical and sanitary requirements;
• operating instructions.

All documents specified in the list are drawn up by the manufacturer and must accompany any product of this type without fail. They are transferred by the seller to the buyer at atgaining device, special attention should be paid to this.

If the project was rejected first time, applicant issued a document stating the reasons for the rejection and a list detailing all project issues that need to be corrected.

If the project is approved, it is certified by the signature and seal of the responsible person. This document is the final approval for the installation of the heater.

Installation Prohibitions

For safety reasons, gas-fired appliances must not be installed in the following rooms:

• in which there are no ventilation systems;
• in hostels (rooms);
• in bathrooms;
• in the corridors and on the balcony;
• in basements;
• on the ground floor;
• on combustible wall surfaces.

One important clarification on installation in the basement and basement: installation allowable only in private single-family house, those. if the house not divided to multiple owners.

Unit installation requirements

Installing boiler on gas, the homeowner must strictly comply with a number of regulatory rules:

• boiler it is installed in such a way that there is a free approach to it from any side;
• the size of the entrance door to the boiler room where the device is installed cannot have a width of less than 80 centimeters;
• area of ​​the boiler room or other room, cannot be less four square meters;
• the boiler room should have a window with an area least 30 cm² per 10 m³ volume - to provide lighting in any situation;
• the ceiling in this room must have a height of at least two and a half meters;
• water must be supplied to the boiler room;
• the ground loop is mandatory if the operation of the boiler is connected with the consumption of electricity;
• the walls of the boiler room must be plastered;
• the chimney must have a section corresponding to the power of the unit.

Having considered the requirements, we can conclude that a kitchen can become a good enough room for installing a hinged boiler, if it is not possible to arrange a boiler room. There it can be placed next to the gas stove.

Compact wall-mounted boiler can fit even in the kitchen

An additional advantage of installing the boiler in the kitchen is that it provides for all of the above requirements. — these are ventilation, gas supply, proper area of ​​​​the room, cold water supply. In addition, by setting boiler, you can save a lot on pipes and keep more than one wall intact.

Floor boiler, having massive dimensions and power from 150 kW, must be installed in a separate room — boiler room. In this case, it should be taken into account that a device with a power of up to 60 kW can be installed in a room with volume not less than 27 m³, and means, it can be installed in the kitchen.

For outdoor it is better to allocate a separate room

But you need to be aware that floor-standing boilers are quite noisy, so if you plan to install the unit in an apartment, then it is better to choose a wall-mounted option.

If a boiler hung or installed on a wall made of combustible material, her must be protected with a heat-resistant insulator, for example, fit special drywall or asbestos sheet.

Boiler installation

Installation of any gas equipment is carried out by a gas master, its independent installation is strictly prohibited. The manufacturer attaches the boiler installation diagram to the documentation of the heater, and it will be useful to the installation master.

The equipment of the boiler house will require the intervention of experienced professionals

1. When installing the unit in the boiler room, the floors must be properly arranged. They must be made of non-combustible material and have a drain for water. It is necessary for the selection of the coolant from the heating circuit in case of an emergency.
2. Installation of gas equipment is not carried out at sub-zero temperatures, it must be at least five degrees Celsius. But even at too high a temperature, it is unsafe to install equipment, so it should not exceed 35 degrees.
3. A mark is made on the wall according to the level for the bracket, on which it will then be hung boiler.
4. If a double-circuit gas appliance is installed, then on the pipe return lines strainer is installed. It is necessary to keep the heat exchanger clean for a long time. Ball valves are placed on both sides of the filter and on the boiler nozzles.
5. Connecting boiler to the gas supply line, in front of it is installed counter for gas, special gas cock, gas detector and thermal shut-off valve.
6. Outlet to be plugged into boiler, if it is volatile, necessarily must be grounded.
7. When the boiler pipes are connected to the water supply and gas supply, the system must be filled with water. This is done slowly so that air does not stagnate in the future coolant. — he will have the opportunity to leave the circuit by air outlet fixtures. For the period of filling the system boiler need disable from power supply.
8. Before as run boiler, be sure to check the gas pipe connections for gas leaks. This is very easy to do — you need to knock down a thick foam from any detergent funds and apply with a sponge her for connecting elements. If a there is a leak, then a soap bubble will surely inflate, and if the pipe is tightly connected, the foam will gradually settle. Only after all these manipulations can you start the system by connecting her to electricity supply.

Ventilation

It is very important to provide the room where the gas appliance is installed with good ventilation.

Supply and exhaust ventilation is a prerequisite for any boiler room

1. The kitchen in a multi-storey building is equipped with a common house ventilation system, so there will be no problems with it. When installing the device in a boiler room, the ventilation duct is arranged in the ceiling of the room and led out.
2. Supply ventilation can be arranged in the door by making a hole and installing a ventilation lattice.
3. Special norms are defined for ventilation inlet openings. So, for one kW of device power lattice must be at least 8—10 cm² (nretreat air outside the house) and not less than 30 sq. cm (air intake from the inside - from other rooms).

Chimney

Particular attention - the correct organization of the chimney

Proper installation of the chimney is just as important as the ventilation system. The chimney can be made of a metal sandwich pipe that exits through the roof of the boiler room (or through the wall) and rises along the wall from the outside to the roof.

Convenient and reliable sandwich pipes

Maybe and coaxial, coming out through the wall and having a small size. Each of them is installed certain rules.

1. Combustion products must not enter inside premises, and means, The flue duct must be gas-tight.
2. The diameter of the chimney must not be less than the diameter of the pipe coming out of the boiler. The ratios for the power of the boiler have been established - the homeowner will definitely be acquainted with these figures when drawing up project documentation.
3. The head of the metal pipe must rise above the roof at least her skate — this will ensure the normal removal of gas combustion products and prevent back draft.
4. When the chimney is led through the wall, a hole is made for it, the pipe is connected to the boiler and withdraw outside. If gaps have formed in the hole between the wall and the chimney, they must be hermetically sealed. Such a coaxial type flue duct fit for a boiler with a small or medium power, and is usually used for mounted models.
