Features of installing wall-mounted gas equipment
It is worth noting that a wall-mounted double-circuit boiler is a self-sufficient system and the installation of such equipment and its connection to existing networks does not cause difficulties. In order to install and connect a gas boiler, the following components are used:
- ball valves for cutting off water lines and heating circuits;
- various surges;
- coaxial chimney that comes with the boiler.
To ensure the protection of the boiler from various impurities, it is necessary to install a number of filter elements: gas, magnetic and coarse filter. Gas wall-mounted boilers are installed in the following sequence:
- The Neva Lux boiler is installed on the wall using special strips that are included in the kit. To securely attach the mounting strips to the wall, it is best to use anchors.
- Ball valves are installed at the inlet and outlet of the boiler of the DHW and heating circuits. This will facilitate further preventive maintenance of the unit.
- Then comes the installation of all the necessary filters using suitable filters.
- After this, you can begin installing the heating circuit and DHW, or make a connection to existing pipeline systems.
All gas connections and filter installation must be carried out by gas company employees who have permission for this type of work.
Advice! It is best to install the Neva Lux boiler in the kitchen or in another room of a private house where there is a ventilation hole. This is due to the rules for using gas equipment and general safety. Also, when choosing an installation location, you should take into account the convenience of supplying communications: water and gas pipes, electrical wiring.
The simple design and reliability of Neva Lux gas boilers is confirmed by numerous consumer reviews. After proper installation, there is no need to worry about the safety of the equipment. Modern automation allows you to avoid emergency situations even in the event of emergency situations: a power outage or a drop in pressure in the gas line.

How to buy a gas boiler and not make a mistake?
A buyer, choosing, for example, a wall-mounted gas boiler Neva Lux 8224 reviews for which may be false and written to order, must understand that they cannot be relied on. After all, it often happens that the design is ideal, the equipment is the most modern, but poor-quality assembly worsens all the advantages. For example, in 2014, reviews characterized the wall-mounted gas boiler Neva Lux 8224 as a naturally raw product, which is called “finish it with a file.”
This review appeared due to poor quality assembly, as well as due to unstable operation of the boiler due to a defect in the coaxial chimney, which was not specified in the instructions. Of course, the Neva company has now taken certain measures and eliminated shortcomings in the assembly of the product. There are practically no complaints about the Lux 8618 model and you can buy a single-circuit wall-mounted gas boiler Neva Lux, with delivery to any region, in specialized stores.
Prices for mounted gas boilers depend on their power, type, configuration and demand for the device. For example, the Neva Lux gas double-circuit wall-mounted boiler offered by many online stores, the price of which with a power of 24 kW, but with different configurations, ranges from 31,800 to 35,600 rubles.
The most expensive boiler, Nevalux 8224, is equipped with a built-in storage boiler. When choosing a boiler for heating, if you are satisfied with the gas boiler Neva Lux 8224 price, it is best to get reviews from real owners or gas equipment specialists.

First aid after the release of the victim depends on his condition. If he's in
consciousness, then you need to provide him with complete rest for a while, not allowing him to move until the doctor arrives.
If the victim is breathing very rarely and spasmodically, but a pulse is palpable, you should immediately
perform artificial respiration using the “mouth to mouth” or “mouth to nose” method.
If there is no breathing, immediately take the victim to a warm room with fresh
air and perform artificial respiration until the doctor arrives.
