ATTENTION! Maintenance operations and repairs of geysers associated with dismantling its gas or water communications must be carried out by qualified craftsmen. Self-repair can have the opposite effect before purchasing a new device.
Error E1 - no flame
The ignition clicks for about a minute, the burner does not ignite. The electronic control unit does not see the presence of a flame and the column goes into emergency mode.
Reason #1. Presence of air in communications. If the column is idle for a long time, or after its installation, the pilot burner will operate only after air has been removed. The system should be purged by constantly turning on the column. Since ignition lasts no more than a minute, after completion you should reopen the water tap until ignition occurs.
Reason #2. There is no gas in the cylinders or the tap on the downstream side of the dispenser is closed. Open the shut-off valve completely. Check LPG gas cylinders. Replace them if necessary.
Reason #3. There is no contact between the block and the flame sensor. The contacts coming out of the electronic unit should be serviced, if necessary, cleaned, pressed for a good connection, and worn ones should be replaced.
Reason #4. Flame sensor outside the flame zone. Adjust the position of the flame sensor so that its electrode is in the gas combustion zone. Make sure that the electrode does not touch other metal components. Clean the electrode from carbon deposits.
Reason #5. The gap between the spark plug and the igniter is broken. Due to constant heating and cooling, the ignition burner nozzle is deformed, which increases the gap to the spark plug. Once every two years, or during regulated maintenance, the gap should be adjusted to 4...5 mm.
Model range of gas boilers Neva
The units produced by Neva are divided into two series: Lux and Turbo. Devices belonging to the Lux series are divided into two categories:
- Single-circuit wall-mounted gas boiler Neva Lux. Intended only for supplying the home 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 modulating burner, which can change the combustion intensity based on the specified temperature, the device is highly economical. The boiler operation can be switched to liquefied gas. Neva gas single-circuit wall-mounted boilers have gained wide user demand also due to their low price, simple maintenance, and the absence of volatile components that are subject to voltage drops in the network.
- Double-circuit wall-mounted gas boiler Neva Lux. Such devices have open and closed combustion chambers, as well as a bithermal heat exchanger. The chimney can be either coaxial or traditional. The heating process of the coolant is controlled by highly precise automation. The maximum distortion from the specified 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 heated floors.
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 the room is.
Error E7 - lack of gas
The speaker goes out after switching on. Unsuccessful ignition attempt. Process: the igniter lights up, then the main burner, then everything goes out and the process repeats again.
Reason #1. Low gas pressure. Open the gas valve on the downstream side of the column. Invite a specialist to your home to measure the gas pressure in the system and further configure the column. You should also blow out and clean the gas filter.
Reason #2. The flame ionization sensor is not located in the fire zone of the main burner. Adjust the sensor. Install the electrode so that the fire of the main burner washes on both sides. It is possible that carbon deposits have formed on the sensor, which makes heating weak - clean and adjust the sensor.
Reason #3. The mechanism in the water unit is stuck. Increased deposition of salts on moving mechanisms leads to jamming and stopping. A stuck rod of the water unit leads to a permanent short circuit of the flow sensor. In this case, you should dismantle the water part and carry out preventive work: lubricate the rod, replace rubber gaskets.

Error E8 - no traction
The column turns off after 2..5 minutes of operation. Restarting becomes possible only after cooling down - 2..3 minutes.
Reason #1. Lack of draft in the chimney. Clean the chimney.
Reason #2. Soot on the heat exchanger. Increased accumulation of soot on the heat exchanger, which prevents the passage of carbon monoxide into the chimney. To resolve the problem, the column must be serviced.
Reason #3. The traction sensor is faulty. The traction sensor works to break. Over time, the sensor becomes very sensitive to vibrations and may turn off the column during heating. Therefore, if this error occurs, the sensor will be checked for functionality.
History of the Neva company
Russian users are well aware of the single-circuit and double-circuit wall-mounted gas boiler Neva Lux. But not everyone knows that the company producing 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 water heaters, boilers, and heaters. Currently, the company belongs to the largest concern “Baltic Gas Company”.
Thanks to this alliance, models such as the Neva Lux and a new product on the market - the Turbo model - appeared. The shortcomings 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.
Error H1 - insufficient heating
The column does not heat the water to the set temperature.
Reason #1. The temperature is set to high and the pressure is high. The column cannot heat the amount of water that passes through the column. Reduce pressure.
Reason #2 . The burner is clogged with dust. If you notice that the gas is burning orange and the flame is sluggish and elongated, then it’s time to clean the burner. If you neglect cleaning, this error will appear constantly. The column efficiency will decrease by half. A lot of soot will appear.

Boiler Neva Turbo
Users left various reviews about the quality and ease of use: 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.
Boiler Neva TURBO 24
All shortcomings were taken into account here. The technical characteristics of the models are as follows:
- closed combustion chamber - here there is a forced air supply through a fan.
Smoke removal is carried out using a special device through a coaxial chimney; What are gas boiler fans needed for and what types they are, you can find out in this article - automation - 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 equipment operation and heating regulation. The package includes an autodiagnostic system, which automatically carries out a test, the results of which are displayed on the liquid crystal display;
- control is on regular buttons. Using a conventional regulator, you can set the desired temperature mode, provided that the programmer is installed, you can select operating conditions for several days or a week. The additional kit includes a room thermostat. The sensor issues a signal to turn off the heating when the room is heated to the desired temperature.
Turbo boilers are energy-dependent units. Electrical power to the boiler is achieved by connecting to a regular voltage network of 220 V.
Safety system
Any gas equipment must have a reliable safety system. The manufacturer of geysers Neva pays special attention to this. All modern models have several degrees of protection and are equipped with special sensors that monitor the operation of the water heater.
- Safety valve. If the pressure in the system increases, it stops the supply of gas and water.
- Flame or ionization sensor. Gas control, which, if the burner goes out, stops the gas supply to it.
- Thermal relay. Protects the device from overheating. In case of strong heating, it turns off the system.
- Water pressure sensor. It activates and stops automatic gas supply when the water is turned on.
- Temperature difference control sensor. If necessary, changes the water temperature when connecting and disconnecting several water intake points. This device is installed in geysers of updated models Neva Lux 4514, 4513.
Installation and connection
Installation and piping of the Neva Lux floor-standing boiler
Neva Lux boilers are installed as follows:
- The equipment is hung on the wall with special strips.
- Ball valves are installed at the inlet and outlet of the boiler to facilitate operation and repair.
- Filters are placed using squeegees.
- The hot water supply and heating system is supplied, or the boiler is connected to the existing water supply.
The boiler must be connected and configured by certified employees of the gas company. Neva Lux is usually located in the kitchen or utility room with a ventilation system. When choosing an installation location, you should take into account the locations of water and gas pipes.
Ignition methods
The following types of ignition are found in the model range of gas water heaters from this company.
- Ignition burner (for example, in the Neva 3208 model).
There are some features of its use indicated in the manual. So, before the first start, the igniter must be ignited manually. To do this, two buttons are pressed simultaneously: gas and piezoelectric device. At this moment, gas and a spark are supplied to the igniter, resulting in a flame that will burn continuously. After the user opens the tap, the main burner will light from the igniter, and after a short period of time warm water will flow. Geyser Neva 3208 - Electric ignition. The principle of operation is the same as in piezo ignition, only instead of an igniter, an electric source is used, which is powered by batteries. This method is economical (in terms of gas consumption) - it is a modern version of gas water heaters. Models with electronic automatic ignition include the gas water heater Neva 4511, as well as models 5011 and 5014;
Geyser Neva 4511
- Hydroturbine ignition. Its action is based on the pressure of the water flow. The main advantage of such geysers is automatic and safe operation, independent of batteries. But such models cost an order of magnitude higher.
The most popular are gas water heaters with electric ignition. They are easy to use and affordable.
Maintenance and operation
Regardless of which model you prefer, installation of a wall-mounted boiler is carried out in the shortest possible time without any additional costs.
The manufacturer places the main emphasis on ease of installation and subsequent operation of the unit. That is why the heating devices of the Neva Lux company are a completely ready-to-use station. All you need to do is connect the equipment to the heating system and power supply and start heating the room. As practice shows, all work takes 3-4 hours. After installation has been completed, there is no need to worry about the safe operation of the station. Consistent operation of the automation reduces to zero the risk of gas leaks and emergency situations, even in the event of an unplanned power outage.
Features of domestic geysers
Geysers of the domestic Neva brand are adapted for Russian water supply systems. As stated, the water heater continues to operate even if the pressure is less than 13 mBar. Following the data in the operating instructions, the Neva gas water heater will begin operating at a pressure of 0.2 atmospheres. However, continuous operation of the equipment under such conditions should be avoided.
In the Neva 4511 model, the instructions provide for normal operation of the device at a pressure of 0.10 bar.
Separately, it is worth mentioning about technical maintenance. In most cases, the service of imported geysers does not satisfy consumers. Even if the part needed for replacement is selected, its delivery may take a long time. And not many service centers undertake the repair of foreign speakers. The state of affairs is completely different for domestic gas instantaneous water heaters. For example, the Neva Transit gas water heater has a removable heat exchanger. The price of the component part is about 4000 rubles. It is this part in such devices that is most vulnerable.
Another advantageous feature of Russian systems is the price segment. The cost of such devices, unlike imported models, is cheaper. In addition, such systems can operate properly for 7-10 years.
Water heater power
This indicator is determined by the volume of warm water at the outlet. It is logical that the more liters of water the system produces, the more powerful it is.
All geysers can be divided into:
- small, their power is from 17 to 20 kW;
- medium, from 20 to 26 kW;
- large, from 26 to 28 kW.
Low-power equipment is suitable for only one water intake point. If you plan to install a water heater to supply several systems, then you should choose more powerful options. For example, for 2-3 water intake points, according to its technical characteristics, 5011 or 5014 geyser . These are systems with automatic piezo ignition, their power is 24 kW. Reliable equipment that can properly perform its assigned functions under long-term operating conditions.
