5.3 Internal gas equipment of a residential building

5.3.1 Characteristics of cold. premises of a residential building

In the choz. a meter and a gas wall thermal block are installed in the room. Room height 2.50m. The area of ​ ​ the choz. room is 11.06m 2. Volume - 27.65m 3

In the choz. the room has a window. Total glazing area complies with SNiP 31012003 standards and is 2.60 m2. Hoz. the room has the existing ventilation channel Ø130mm.

5.3.2 Characteristics of the kitchen room of a residential building

In the kitchen room there is a gas stove "Beko CG 41001" of the company "Arcelik A.S.." Kitchen height 2.75m. The kitchen area is 28.26m 2. Volume - 77.72m 3

There is a window in the kitchen room. Total glazing area complies with SNiP 31012003 standards and is 2.40 m2. Kitchen room has existing ventilation channel Ø130mm.

5.3.3. Gas flow metering unit.

To account for gas flow to the farm. BKG4 type counter is installed in the room

Apator Metrix S.A. (Poland). Measurement limits 0.046.0 m3/h

5.3.4 Equipment characteristics:

For heating and hot water supply in the farm. thermal block "Vitopend 100W" from "Viessmann" Germany is installed in the room. Thermal unit power 24kW, gas pressure 13 20 mbar, gas flow 2, 83 m3/h. Installation of gas heating boilers should be provided for walls lined with non-combustible or difficult-combustible materials (with insulation by roofing steel on asbestos sheet with thickness of at least 3 mm) at a distance of at least 10 cm from the wall and at least 1 m from the opposite wall.

The thermal block has a coaxial smoke removal system (chimney with air duct and chimney "pipe in pipe"). Air to burn comes directly from the street. Thermal block has closed combustion chamber.

For food preparation, a gas stove "Beko CG 41001" of the company "Arcelik A.S." is installed, with a capacity of 12.5 kW with a gas flow rate of 1.33 m3/h.

Walls of combustible materials in places of installation of gas plates should be insulated with non-combustible materials: plaster, roof steel on asbestos sheet with thickness of at least 3 mm, etc. The insulation shall extend beyond the plate dimensions by 10 cm on each side and not less than 80 cm on top. The distance from the slab to the non-combustible insulated walls of the room shall be not less than 7 cm; the distance between the plate and the opposite wall shall be not less than 1 m.

Supply to gas equipment is performed by flexible current-conducting hoses.

5.4 Smoke removal and ventilation

Combustion products and air supply for combustion are carried out through coaxial system of pipes (60/100) brought directly to the street. The hole of the smoke channel on the facade of the residential building when discharging combustion products through the external wall without a vertical channel device should be placed at a distance of at least:

2.0m from ground level.

0.5m - to windows, doors and open veins. holes.

0.5m above the top face of windows, doors and open ventilation grilles

1.0m - vertically to the windows when placing holes below them.

Since the thermal block has a closed combustion chamber and the combustion air is taken directly from the street, in order to ensure 3x air exchange, it is necessary to provide a gap with a living section of 0.02 m 2 in the lower part of the door opening to the neighboring room and the existing ventilation channel. The act of inspection of chimneys and ventilation channels shall be applied.

6 Construction organization

The development of this section by the contract for the performance of design works is not provided.

The construction is carried out in accordance with the PDP and the schedule developed by the contracting organization, agreed with the customer at the stage of signing the contract.

PPB0193, "Rules for devices and safety of pressure vessels operation."

Safety instructions for workers of each profession, taking into account the specifics of local conditions, must be developed in the construction organization and approved by the chief engineer.

8 Emergency Prevention Activities

Engineering and technical measures of the Ministry of Emergency Situations are carried out in accordance with the requirements of SNiP 2.01.5990, SNiP 110195, SP 11-107-98

"Engineering measures for emergency prevention." In accordance with the instruction on the categorization of facilities of the national economy, the gas pipeline refers to non-classified facilities and the development of special civil defense measures is not required, except for compliance with safety measures during its operation.

The Customer shall conclude a contract with the licensed operating organization for maintenance of the internal equipment of the building.

9 Occupational Safety Recommendations

Before commencing construction and installation works, workers are required to undergo safety and health training in their organization and obtain admission to work.

An entry must be made in the work log. The workplace should be safe for the employee, namely:

During operation, workers must be equipped with special clothes and sleeves;

metal welders shall have protective shields of appropriate light resistance;

You cannot be in the working area of the mechanism;

it is not possible for unauthorized persons and children to be on the construction site.

For more complex types of work, the contracting organization must fulfill the AKP and approve it with the chief engineer of the construction organization .

10 Recommendations on environmental protection

To reduce air pollution during construction, the project recommends the following activities:

Compliance with technology and quality assurance of works performed, including alterations.
