Installing new and reinstalling existing gas appliances with laying additional supply paths, how to do it correctly and legally
Today, the use of gas equipment for various purposes remains relevant, both in their own homes and in urban apartments. To obtain heat, hot water, fire for cooking, you will need to install gas appliances for various purposes. Since natural gas is inherently not only combustible, but also explosive, its handling requires accuracy and compliance with the rules for use, gas equipment must also be installed in accordance with existing standards, by qualified specialists. Now consider the installation rules that apply to the most commonly used gas equipment in everyday life.

Gas boiler installation
Natural gas boilers are devices with a high fire and explosion hazard, therefore, compliance with the standards for their installation should be foreseen when designing a house. Compliance with the stipulated state standards is also mandatory if the room for the boiler room is selected in a house already in operation. The requirements for installing a gas boiler can be divided into several groups.
room requirements
Requirements for the boiler room: it must be separate, in no case be a living room; the height of the ceilings in it should be more than 2.2 m, area - 4 sq. m .; walls and floors should not have a fire hazard coating; the width of the doorway is 0.8 m, the size of the outer window is at least 0.3 sq. m for every 10 cubic meters of the room.
A prerequisite for the functioning of the boiler room is the supply of electric current (20 A, 220 V), the installation of an individual circuit breaker, grounding equipment. Water is supplied and it is possible to connect it to the hot and cold water supply system. A sewer system will also be required for emergency evacuation of effluents from the boiler and water supply system.
An important condition is compliance with the standards of communication parameters, such as the pressure of water in the system and gas in the pipeline.
The boiler room must be provided with a high-quality ventilation system and a chimney. In order for fresh air to enter the room, a ventilation grill is installed in the door. Detailed information about the requirements for the boiler room can be specified in SNiP.
chimney
The chimney must not be gas permeable - otherwise the products of gas combustion will enter the boiler room. The exhaust openings for the chimney must correspond in area to the chimneys of the boiler. To ensure complete removal of gas combustion products, the room is equipped with a chimney, the height of which exceeds the height of the roof.
where to install the heating unit
The rules for installing a gas boiler recommend placing it at the maximum possible distance from sources of open flame. Access to the boiler must be from either side. If the removal of flue gases in the boiler is forced, then it is not necessary to equip the forced draft system, it is sufficient to install a fan in the chimney, the pipe of which will exceed the height of the roof ridge in height.
To increase the efficiency of the boiler, they resort to the construction of a coaxial chimney, which helps to supply air from the outside through an external annular channel. The use of a double pipe allows you to heat the air supplied from the outside with the help of volatile gas combustion products, which ultimately has a positive effect on the efficiency of the boiler. Given the noisy operation of the boiler, especially in the case of equipment with a fan, it is recommended to install it in a basement or basement. In addition, the installation location of the unit is selected depending on its type (whether it is floor-mounted).
Design and installation work on the installation and connection of the boiler must be carried out by employees of companies that have licenses for the performance of this kind of work, often these services are offered by organizations involved in the retail sale of heating units.
Rules for installing a gas stove
A gas stove, without which a very insignificant part of city apartments and country houses can do today, is a rather dangerous device connected to the gas supply system. A gas leak can cause an explosion or poisoning of residents, therefore, the installation process of a gas stove should be taken seriously, when installing or replacing it, it is best to contact specialists from the gas service. Specialists working in it have relevant experience and qualifications, a license for installation work.
If, due to circumstances, the work is planned to be done with one's own hands, then one should strictly adhere to the instructions, be extremely attentive and accurate, observe safety rules.
After delivering the stove to the room, especially in the cold season, before proceeding with the installation, wait until all parts of the unit have acquired room temperature. The device should be unpacked, evaluate its technical condition. Particular attention must be paid to the nodes that will connect the stove to the gas network. You should also make sure that the gas regulators for the burners are in working condition.
If the stove is equipped with an electric oven, you will need to install an electrical circuit to supply voltage to the switchboard of the stove. Experts do not recommend using old wiring to connect the stove - the cross-section of wires in it is not designed to connect powerful devices, which include electric ovens. The new circuit being created for powering the stove must be equipped with a separate circuit breaker installed on the panel. Grounding should also be provided. The electric ignition of burners can be powered from a conventional outlet, but if it is grounded.
To connect the device to the gas network, you will need a special gas hose, it will need to be examined for leaks, during installation, carefully tighten all mounting connections with a wrench and check for gas leaks.
The plate should be installed on a flat surface, but if there are any flaws on the floor, then the correct installation of the equipment is achieved by adjusting the height of the legs - each of them should stand firmly on the surface. When mounting the hob, you will need to properly prepare and align the installation site.
After installation, a thorough check of the operation of the plate in different modes is required. If you identify even the most minor flaws in the operation of the unit, you should immediately contact specialists from the gas service. Operation of improperly installed or malfunctioning equipment can seriously damage the property and health of its owners.
Gas meter installation
If we are talking about the operation of all kinds of gas appliances, then it will not be out of place to recall a gas meter that will help to control the amount of actually consumed gas, and therefore get some savings, the averaged standard indicators of fuel consumption are often too high.
The gas meter installation rules prescribe the installation of gas to representatives of the organization that provides gas supply, and installation of the gas by unauthorized persons may be refused to owners of the house or apartment.
Measures for installing the meter should be as follows:
- The help desk of the gas supplier will need to find out the address of the office where they accept applications for installing the meter.
- If you are visiting the gas service office in person, after presenting your passport, title deed or rental agreement, receipts for payment of the consumed gas, write a statement.
- If this housing belongs to several apartment owners, then any of them can write a statement.
- Next, the employee’s arrival time is agreed with the company employee, who will perform all the necessary measurements.
- The installation location of the meter should be preliminarily considered - the distance from it to the nearest gas devices should not be less than 0.8 m, the height above the floor should be at least 1.2 m. The owner of the house has the right to choose a place for installation, of course, violate the standards it is not permitted. In order not to spoil the interior of the room, you can agree with the master about installing the control device in the kitchen cabinet or on the hanging shelf - so it will be less evident.
- At the agreed time, you will need to go to the office of the gas company and pay the cost of design and installation work.
- Immediately after this, the arrival time of the wizard to set the counter is specified.
- You can buy a meter in the gas service store or in any other, in the case of a more affordable price of the monitoring device. But at the same time, it should be agreed in advance with the master what type and what parameters the counter should have.
Laying additional conductive paths
If during the development of the project it becomes clear the need for laying additional gas supply paths, then you should know that this process is not simple and requires several stages of work:
- commissioning
- gas pipeline testing
- subsequent technical support.
Each of the work sites requires special knowledge and practical skills, all work must be performed by specialists - employees of the gas service. When performing work, all requirements of design documentation and regulations must be observed.
