click fraud protection

In principle, in his dwelling the owner is free to do anything, for that he and the owner. But if it comes to installing high-risk devices, then all the requirements of the main regulatory documents are mandatory for execution. About what needs to be taken into account and what rules and norms for installing gas equipment to comply with in relation to a private house will be the subject of consideration.

There are no major problems with the use of gas cylinders and the operation, for example, of burners, as a rule. The following is meant equipment that is connected to the central highway. In a private house it is, first of all, a heating boiler. Therefore, the emphasis is on gas devices of this type.

Individual requirements may not be liked by the owner because of the need for some alterations( reconstructions) or for some other reason. And, nevertheless, they will have to be carried out. Otherwise, the gas workers, on another inspection, having discovered "amateur performance", and even with a gross violation of the standards, will simply turn off the supply of "blue" fuel until the remarks are removed. And this is - at best.

Quite often there are disputable situations when the specialists of the resource-supplying organization require the owner of a private house to fulfill any requirements that seem unnecessary or inconvenient to him. Those who want to competently defend their case when installing gas equipment, the author recommends that you carefully study SNiP Nos. II-35 of 1976;41-104 of 2000;31-02 of 2001 and 42-01( 02) of 2002.

A simple example - the rules of 1987( for No. 2-04) prohibit the installation of gas( boiler) equipment( wall-mounted version) in the bathroom. And in replacing this document with the SNiPs of 2002, nothing is said about this. Consequently, there is no longer a ban as such, but some "comrades" from the gas industry continue to insist on moving the device to another room. Here to communicate with such "pros" and you should know all the requirements for installing gas / equipment.

It is understood that all the necessary documents have been prepared, an agreement with gas suppliers to supply "blue" fuel is concluded.




General rules for the installation of gas equipment

  • Gas equipment is installed only in rooms that are suitable for the area( in accordance with the specifications for the device) and the efficiency of ventilation.
  • If this is a private house, the mini-boiler house must have a window whose dimensions correspond to the requirement - the numerical expression of the area ˃ 0.02 "cubic" of the room in which the gas equipment is located( all requirements for the boiler room are described here).
  • The window frame should open and ensure the safety of households with a possible gas explosion. The shock wave should be directed outwards. For this purpose, the glazing of rooms with gas appliances is made "light", single, without installation in the heating( boiler) double-glazed windows or massive frames with 2 glasses.
  • Cylinders and other gas equipment, located outside a private house, is placed in a special stand near the wall. Access to it should be free( for ease of monitoring and maintenance).
  • All works on installation and connection of gas equipment are carried out by specialists of resource-supplying or other certified organization for this type of activity. Self-installing is fraught not only with problems with the normal operation of the product, but also the manufacturer's warranty is null and void.

Assembly requirements for

They are detailed in the instructions for each gas appliance. Their observance is a guarantee not only of safety, but also of the fact that in the event of a failure of the technique, the user will be able to count on a free replacement of both a separate node( component) and the entire installation in the specified period. Therefore, the specification for the boiler( stove or other gas equipment) is one of the basic documents on the order of installation.

Further, only general requirements for devices of different classes are noted. Before proceeding with the installation of equipment such as a gas boiler, it is necessary to clarify that it must be prepared for it - a furnace or mini boiler house. This is indicated in the product data sheet. In the latter case( for the boiler room) the requirements are somewhat more stringent.

demands

Gas floor boilers

  • The base for the equipment is fire-resistant.
  • Minimum distance from structures: combustible - 50 cm, non-combustible - 100 cm.
  • For convenience of inspection, maintenance and repair of gas equipment along its perimeterbe a free zone( within 1 m from each side).
  • The area of ​​a mini-boiler house in a private house is from 4 "squares" with a ceiling height of at least 2.5 m. At the same time, a minimum of 8 m³ of free space should be provided.
For gas boilers with a closed-type combustion chamber, many requirements are not relevant. The room volume in this case is not normalized, the presence of a window is not a mandatory requirement for the installation of gas equipment.
  • The width of the door leaf is from 80 cm and more.
  • The air intake is natural, based on the 8 cm2 product area per kW of the gas appliance.
  • Smoke extraction system with pipe outlet outside. The configuration of the channel, the cross-section of the elements are calculated individually for a particular private house, depending on the material of the walls, the wind rose and a number of other factors.

For the flue system it is advisable to give the general rules for the installation of gas equipment:

  • The minimum permissible elevation above the roof( skate): flat - 1.2 m, pitched - 0.5 m.
  • No pipe joints within the ceiling overlap.
  • The chimney must not be located closer than 100 cm along the length of the route in relation to materials of the category "flammable".

Wall boilers

Given that this equipment has a power limit, the requirements for its installation are not so numerous.

  • The minimum distance to other devices, combustible materials is 0.2 m.
  • Distance from the floor covering is from 0.8 to 1.5 m( at the bottom edge of the gas appliance).
  • For private houses made of wood, a non-combustible layer between the wall and the boiler( for example, an asbestos cloth) is mandatory. The minimum thickness of the "protection" is 3 mm.

Installation of such equipment is much easier. The stove is placed in the kitchen, hence the opening window flap, and the hood is by definition. Where the device to place, the owner decides, depending on the ease of use and overall design of the room. But the connection to the highway may only be carried out by a licensed specialist. It is only necessary to take into account that the ceiling height( maximum, minimum) is 2.20 m.

Do not use

  • Use combustible materials for furnish, arrange false floors and so on.
  • Produce welded joints for the installation of gas equipment - only on threads.
  • Route the internal gas line from pipes other than steel pipes. In some cases it is allowed to connect gas appliances with a special flexible hose.

Recommendations

  • Gas equipment operating from the power line / voltage network should be connected via stabilizers.
  • In order to simplify the installation of the smoke removal system and increase the efficiency of the boiler, it is advisable to install coaxial type chimneys.
