Error codes for the gas boiler Neva Lux - malfunctions and what to do in a specific situation

Description of the gas wall-mounted boiler Neva Lux 8224

Double-circuit gas wall-mounted boiler Neva Lux 8224 with a closed combustion chamber is intended for apartment heating and hot water supply in multi-storey buildings, as well as in private suburban areas up to 240 m².

Safety

Gas wall-mounted boiler Neva Lux 8224 absolutely safe to use. The manufacturers have provided for all possible emergency situations. The gas supply to the boiler is automatically stopped when the burner flame goes out, the heating medium heats up to a temperature of more than 90 ° C, irregularities and problems in the smoke exhaust system, a power outage, as well as when the pressure drops below the maximum permissible level.

Built-in functions of anti-freezing, automatic protection against blocking of the pump, "acidification" of the three-code valve. If the pressure in the heating system rises above 3 bar, the coolant is discharged.

In the event of a malfunction, an electronic self-diagnosis system displays error codes on the display.

Separate heat exchanger system

The gas boilers Neva Lux 8224 have two heat exchangers: a copper one for the heating circuit and a secondary stainless steel plate heat exchanger for hot water supply. In practice, this means that hot water supply and heating are less dependent on each other than when operating boilers with a bithermal heat exchanger. In addition, boilers with separate heat exchangers are less demanding on water quality.

The use of a system of two separate heat exchangers can significantly reduce the likelihood of scale formation in the primary heat exchanger, thereby reducing service costs and extending the life of the device.

By purchasing Neva Lux heating equipment, the consumer receives not only a comfortable atmosphere in his home, but also a durable "partner", as well as quality and reliability. Gas boilers Neva luxury, among other things, are still quite a democratic option for large country houses and small country houses. Which of the Navien gas boilers to choose, read on this page.

History of the company Neva

Russian users are well aware of the Neva Lux single-circuit and double-circuit wall-mounted gas boiler. But not everyone knows that a company that produces such equipment appeared on the market more than 50 years ago.

The original enterprise was called Gazapparat. It specialized in the production of any gas equipment, including columns, boilers, heaters. Currently, the company belongs to the largest concern Baltic Gas Company.

Thanks to such an alliance, such models as the Neva Lux and a new product on the market - the Turbo model, appeared. Deficiencies in the work of the first models were taken into account and were eliminated in subsequent ones. As a result, the consumer receives a product of European quality.

Lineup of gas boilers Neva

The units produced by Neva are subdivided into two series: Lux and Turbo. Devices belonging to the Lux series are divided into two categories:

1. Single-circuit wall-mounted gas boiler Neva Lux. Designed only to supply the house with heat. If you connect an indirect heating boiler, then such a unit will be able to provide the house with hot water supply. Due to the fact that the device includes a modulation burner, which can change the intensity of combustion based on a given temperature regime, the device is highly economical. Boiler operation can be converted to liquefied gas. Gas single-circuit wall-mounted boilers Neva have found wide demand from users also due to their low price, simple maintenance, as well as the absence of volatile nodes that are subject to voltage drops in the network.
2. Double-circuit wall gas boiler Neva Lux. These devices have open and closed combustion chambers, as well as a bithermal heat exchanger. The chimney can be either coaxial or traditional. The process of heating the coolant is controlled by highly accurate automation. The maximum distortion from a given temperature regime is no more than 1%. Another key difference between a double-circuit wall-mounted gas boiler is the ability to connect two heating systems at once. There are outlets for underfloor heating.

If you connect a thermostat, you will significantly reduce gas consumption and the automation will function completely independently. The control unit will automatically adjust the heating of the coolant based on how warm it is in the room.

The main technical characteristics and features of the equipment of the company Neva

Note that wall-mounted gas boilers on the market are presented with an open and closed combustion chamber. What does it mean? In the first case, the removal of combustion products is carried out in a natural way, through the chimney to which the device is connected. The air intake required for normal gas combustion is carried out from the room.

In the second case, the gas boiler is connected to a coaxial chimney, the device of which is made according to the "pipe in pipe" principle. The combustion products are forced out through the inner pipe, thanks to the built-in fan, and air is supplied through the outer pipe, which comes from outside the room.

Wall-mounted double-circuit gas equipment is capable of performing two tasks aimed at heating the coolant and sanitary water. Heat exchangers are installed separately, one is designed for heating the coolant, the second for heating sanitary water.

Household appliances of this type are distinguished by a wide power range, which allows you to choose a unit for installation in an autonomous heating system for a house of any size. When choosing a device, it is important to take into account that 1 kW is required for normal heating of 10 m 2. So, if a house, for example, has an area of ​​200 m 2, in which there is a need for hot water supply, then in order for the system to work stably, efficiently and economically, you will need to buy a Neva double-circuit gas boiler of any model with a capacity of 24 kW.

Design features of the "Neva" boiler

Despite the fact that the Neva wall-mounted boiler is small, its design contains everything necessary for the stable and high-quality operation of the equipment. Therefore, by opting for these heating boilers, you will not need to buy a separate circulation pump or expansion tank, the task of which is to remove air from the heating system in a timely manner. According to experts, the built-in expansion tank can significantly increase the safety, reliability and stability of the heating system.

The main advantage of the built-in expansion tank from the external tank is that there is no need to constantly check the coolant level, the equipment will do it for you. In addition, since the need to install the expansion tank has disappeared, it is possible to significantly save on the design of the heating system.

All models of gas boilers presented by Neva are equipped with pressure gauges installed on the equipment panel. It is important to know that as the temperature rises, the pressure in the system rises and vice versa. The system should be replenished if the pressure drops below 1.5 atmospheres. Note that Neva wall-mounted appliances are able to continue to work effectively at reduced gas and water pressure.

Let's return to the contours of the device, namely to the one that is responsible for heating the sanitary water intended for everyday needs. So, for its manufacture, stainless steel is used, the advantage of which is high resistance to corrosion, due to which the durability of the device increases.

If you want to extend the operating period of your equipment, it is recommended to install a filter on the water supply pipe through which water is supplied to the boiler, with which the water will be purified and softened. Cut-off valves should be installed in front of the filter and on the return line, which will allow you to easily perform equipment maintenance and filter replacement.

Only when you understand all the technical characteristics of the device, you can proceed to familiarize yourself with the control system of the unit. Immediately, we note that the Neva Lux double-circuit gas boiler in operation is very simple and convenient, despite its equipment and high efficiency in operation.

On the equipment panel, you can see two regulators, one regulates the heating of DHW, the second the temperature of the coolant with which the heating system is filled. If you set any regulator to zero, then the corresponding circuit is turned off, heating will not be carried out. This is convenient in the summer, since it is possible to quickly turn off the heating system, but leave the unit running to heat the sanitary water.

If you need to restart the equipment or reset the initially set parameters, just press the button located next to the temperature controls.

In order for the device to start working, it must be turned on and, with the help of the regulators, set the desired temperature for heating the DHW and the coolant. Note that as soon as the coolant heats up to the set temperature, the equipment will automatically turn off, which allows you to save a lot on heating due to low fuel consumption.

In case you do not live in the house for some time, a special program is provided that allows you to set the equipment to work at a minimum temperature, which will only be enough to keep the heating system from freezing. In addition, the equipment can be easily programmed to turn on at a specific moment, for example, three hours before you come home from work.

If for some reason the gas supply to the wall-mounted gas boiler Neva double-circuit is turned off, it can be set to a mode that will not allow the system to freeze. The essence of this function is that the burner is turned off, and the circulation pump continues to work, thereby circulating the coolant through the system. Of course, the temperature of the coolant will decrease, but on the other hand, in motion, the water will not freeze longer.

Boiler operation with air temperature sensor

In the event that such a sensor is not installed, the gas boiler will turn on only when the temperature of the coolant drops below a predetermined limit that operates in the heating system. If a decision is made to install the sensor, then it is recommended to place it in the farthest room of the house.

The main advantage that the Neva double-circuit wall-mounted gas boiler pleases is that it is possible to install an external temperature sensor. Such a sensor will allow you to regulate the heating of the coolant as accurately as possible, based on the outside air temperature.

The outdoor sensor should be installed only in a place where it will not be exposed to direct sunlight and wind, it should only respond to temperature changes.

If the installation is performed incorrectly, the boiler will turn on even at positive temperatures, if a cold wind blows on it, and at negative temperatures, it may not turn on if the sun's rays fall on it.

Neva Turbo boiler

On the quality and ease of use, users left various reviews: positive and negative. Over time, all the necessary adjustments resulted in the production of a separate series of heating devices. Neva Turbo units are, by and large, a modified version of the already familiar Lux series.

All the shortcomings were taken into account here. The technical characteristics of the models are as follows:

• closed combustion chamber - here there is a forced supply of air by means of a fan. Smoke removal is carried out using a special device through - a coaxial chimney;
• automatics - wall-mounted gas double-circuit boiler - Neva Turbo is fully adapted for operation. A multi-level system of sensors and valves is responsible for the safety of the equipment and the regulation of heating.The package includes an autodiagnostics system, which automatically checks, the results of which are displayed on the liquid crystal display;
• control - on the usual buttons. Using a conventional regulator, you can set the desired temperature regime, provided that the programmer is installed, select the conditions for operation for several days or a week. The optional kit includes a room thermostat. The sensor generates a signal to turn off the heating when the room heats up to the desired temperature.

Turbo boilers are volatile units. The electric power supply of the boiler is achieved by connecting it to a regular voltage network of 220 V.

Installation features

It is worth mentioning that a wall-mounted double-circuit gas boiler is a self-sufficient system and it is not difficult to install and connect it. In order to carry out the installation and piping of the gas boiler, you must use the following components:

• ball valves, they will be responsible for cutting off water;
• mains and heating circuit;
• all kinds of drives;
• coaxial chimney, which is included in the boiler package.

In order to protect the heater from all kinds of impurities, it is necessary to install some filtering parts: gas, magnetic and coarse filter.

The sequence of installation of a wall-mounted BaltGaz gas boiler is as follows:

1. The Neva Lux unit is mounted by means of special strips that are included in its package. In order to securely fix these planks to the wall, it is best to use anchors.
2. Ball valves are placed at the inlet and outlet of the boiler of the hot water supply and heating circuit. Subsequent maintenance of the unit will be much easier.
3. Next, you need to install all the required filters using suitable squeegees.
4. Then you can start installing the heating and DHW circuit or connect to existing piping systems.

All connections and installation of the filter must be carried out by specialists who have permission to do this.

It is better to choose a kitchen or other room in the house where there is a ventilation hole as the location of the unit. This is prescribed by the rules for the operation of gas equipment and general safety. In addition, when choosing an installation site, you need to take into account the convenience of supplying communications: water and gas pipes, electrical wiring.

User reviews confirm that Neva Lux gas boilers are efficient heating devices. If you make the correct installation, then you do not have to worry about the safety of the equipment. Thanks to modern automation, the risk of emergencies is reduced to zero.

Features of operation

Before starting to use Neva Lux, read the manufacturer's instructions. Yes, the boiler is easy to use, but compliance with basic rules will help to extend the service life and protect the home from unforeseen problems.

There are two regulators on the outer cover of the housing - for heating and DHW. Setting to zero means excluding the loop from operation. Nearby there is a button for resetting the set parameters.

The algorithm of Neva Lux is built on the "plug and forget" principle. It is enough to set the temperature once, and its parameters will not change under any circumstances.

If the electricity goes out, then after the appearance, the mode will be restored automatically.

The control program includes an economy mode that allows you not to turn off the heater during short-term departures. Programming for several days in advance is possible. The remote control panel provides additional convenience to the user.

When the flow of gas stops, to prevent defrosting of the heating system in winter, a mode is provided to prevent freezing of the coolant. In this case, water circulates through the system when the burner is not working.

Neva Lux control panel

Connecting external temperature sensors facilitates temperature control. The sensor is installed in the room farthest from the heater. If the air temperature in it drops below the programmed one, the boiler will turn on (burner) and restore the parameter. It is allowed to install 2-3 sensors at the same time in different places.

The outdoor temperature sensor also makes the task easier, but its inclusion in the circuit is not recommended due to various kinds of interference in the form of solar heating, wind or air with high / low humidity. Install such a sensor in proven places, excluding or minimizing the impact of "harmful" factors.

About the popular Neva Lux 8224

If you need a reliable double-circuit boiler, then it makes sense first of all to take a closer look at this particular model, because it can rightfully be considered one of the exclusive offers on the market for such modest money. What is the peculiarity of this technique?

It is no secret that domestic products at all times have been much cheaper than their European counterparts. And it is precisely the democratic price that is the main advantage of the Neva Lux 8224 model in comparison with imported competitors. In fact, a Russian can, for relatively little money, acquire a modern reliable unit with built-in automation, low fuel consumption and high performance.

It is obvious that the BaltGaz company, striving to satisfy the maximum wishes of the buyer for relatively little money, "presented" the Neva Lux 8224 units with a complete set that is quite extensive for its price segment. Note the following features of this design:

Russian engineers very seriously approached the creation of a universal heating unit, which is evident from the design of the Neva Lux 8224. If you, as a buyer, are looking for harmony between price and quality, then many market experts will advise you on this particular model, because reliability, ease of use and adaptability to Russian conditions are the fundamental advantages of this boiler.

Possible malfunctions

The more complex the technique, the more likely it will fail. This is especially true for the electronics included in the control system. Despite the fact that Neva Lux heating boilers are considered extremely reliable, some types of malfunctions cannot be avoided. More often for reasons other than the hardware itself. This includes:

• Low pressure of gas or water in the system;
• Flame breakage and extinction;
• Mechanical breakdowns.

The built-in self-diagnosis system displays an error code on the display, which is identified by the table on the last page of the manual. You can fix some simple malfunctions in the absence of a warranty yourself, but it is still better to contact the manufacturer's customer support service or directly to the service center.
