Reviews about the rules for installing a gas boiler
Many people like the products trademark"Beretta". A gas boiler from this manufacturer can be purchased at an affordable price. Before you begin installing the device in a private home, you will need to prepare some documentation and carry out certain actions. Thus, you will need a gas supply contract for the developer and an installation project. Specifications must be agreed upon with a gas service representative.
Project documentation is most often developed by specialists from institutes that operate under the appropriate license. Gas equipment must be installed by professionals from installation organizations.
According to users, an engineer from the district organization must visit the site in order to check whether gas is supplied correctly to the kitchen and furnace room, and whether the requirements are met. Quite often in Lately consumers choose Beretta brand products, and the gas boiler is no exception.
After the specialist is convinced that all standards are met, he will issue a conclusion, based on which it will be possible to open the valve that leads to the equipment. The heating system must be pressurized to P = 1.8 atm.
It will be important to de-air the heating system. Advanced users emphasize that the connections must be checked for leaks, it is necessary to install a voltage stabilizer for the equipment and a source that will be responsible for it. It is worth remembering that under no circumstances should antifreeze be added to the heating fluid.
Reviews on the rules for designing a boiler room
When to purchase wall gas boilers"Beretta", they must be installed in premises that have certain requirements. In a private single-apartment house, the boiler room or furnace room can be located on any floor, including the basement, roof, attic or basement. The restriction applies only to residential premises, as well as to the bathroom and bathroom, where it is prohibited to place the boiler. Consumers emphasize that it is important to determine the volume of the boiler room, taking into account thermal power equipment, capacity of water heaters, as well as flow tanks.
For reference
If you decide to install a Beretta gas boiler, then keep in mind that when installing it it is important to take into account some factors. So, if the device has a closed combustion chamber, then the volume of the boiler room is not standardized. It is not necessary to have a window. To remove and supply oxygen, it is important to ensure air flow in the required volume.
Thus, if you installed a boiler with a power of 23.3 kilowatts, then the gas will burn in a volume of 2.5 cubic meters per hour. In order to ensure complete combustion given volume, you need 30 cubic meters air per hour. If you do not guarantee sufficient air supply, the gas will not burn completely and will begin to concentrate as a result. harmful substance, its inhalation can negatively affect human health. If inhaled for just 15 minutes, death can occur. Oxygen must penetrate not only from outside, but also from other areas of the house. This can be ensured by having a gap that will be located between the door and the floor surface. It is also recommended to install a grille at the bottom of the door.
The Beretta gas boiler must be installed on the floor with a distance of ten centimeters from the wall, which should be made of non-flammable material. If there are no such surfaces, then you can install special protection, which will be made of fire-resistant material.
Installation instructions
If the listed requirements are not met, the gas service will not allow you to connect the boiler to the central line. However, the need to comply with these requirements is dictated not by bureaucracy, but by experience, as well as fire safety. The restrictions apply not only to equipment and installation work, but also the premises where the boiler is supposed to be installed.
It must be remembered that the area of the boiler room must be 4 square meters or more, and the ceilings must be at least 2.5 meters. When installing the door, keep in mind that its width should be 80 cm or more. If you decide to prefer the Beretta manufacturer, a gas boiler from this company will meet all safety requirements, but it is important to comply established rules. They require the equipment to be illuminated naturally through a window opening. On 10 square meters One room should have 0.3 meters of square window opening. It is very important to organize intensive ventilation, because gas combustion is ensured by the principle of influx fresh air. To ensure the entry of outside air, it is necessary to ensure the presence of an opening of 8 centimeters square per 1 kilowatt of device power.
Additional Instructions
The Beretta gas boiler, which has only positive reviews, must be connected to gas pipeline pipes that are made exclusively of metal. The use of flexible hoses is permissible only for connecting individual consumers. The chimney must have a cross-section that corresponds to the power parameters of the unit. If it is equal to 30 kilowatts, then the diameter of the chimney should be 130 millimeters. When the power increases to 40 kilowatts, the diameter increases to 170 millimeters. It is impossible to allow the cross-sectional area to be less area cross-section of the hole for connecting this element.
If you decide to choose a Beretta gas boiler, the installation instructions for which are presented in the article, then it is important to remember that the upper end of the chimney should be 0.5 meters above the ridge. This value is the minimum.
What else should you pay attention to?
Be sure to ensure the presence of a gas analyzer, which must be located in the boiler room. By using of this device you can prevent gas leaks. The device must be equipped with an electric valve. The latter is designed to shut off the gas supply if necessary.
The manufacturer "Beretta", whose gas boiler you can purchase at specialized sales points, indicates the possibility of placing the equipment in basement exclusively a single-family house. Concerning multi-storey buildings, then installing the device in the basement is prohibited.
