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 descent to the column is closed. Fully open the shut-off valve. 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.
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.
e1
Error e1. This malfunction indicates low fluid pressure in the heating circuit.
The reasons may be as follows:
- The heating circuit has become airy or the pressure has dropped to its minimum point. Increase the fluid pressure in the system, remove air from the heating circuit.
- The bypass valve is installed incorrectly or is faulty; to check, follow these steps: set the boiler to heating mode, then close the shut-off valve to the heating circuit.
The bypass should redirect the liquid not into the heating circuit, but pass it through the bypass line (at the same time it will heat up). And, if it is faulty, replace it with a new one, installing all the taps in the position in which they were before the check. - Pump failure. It is necessary to remove it from the device, disassemble it, wash it, and clean it of accumulated deposits. If this does not work, replace it.
- There is a breakdown in the electrical circuit of the pressure sensor.
Using a multimeter, test the circuit for an open; if found, repair it. DHW sensor Visually check all contacts and connectors. If this does not give the expected result, replace it with a working device. Occurs often in Neva Lux 2073. - A slow-moving rod or sticking of the measuring device rod in the heating circuit, the cause could be a failure of the membrane on the flow sensor.
To begin, remove this sensor from the device, turn the boiler (pump) on and off, in a similar way you can remove the boiled rod. If this does not work, check the condition of the membrane; if it is worn or deformed, replace it. - There is a malfunction in the flow sensor, or the integrity of the connecting wire is broken. Perform an electrical circuit check and also check the connections of the controller board connectors. If the problem persists, replace the flow sensor. Typical for the Neva Lux 2083 model.
- Failure in the electric motor of the three-way valve. Repair is not possible, complete replacement is necessary.

Design and principle of operation of Neva and NevaLux speakers
The BaltGaz line includes several instantaneous gas boilers, differing in their operating principles and internal design features. All manufactured equipment can be divided into several groups:
- Type of ignition - there are semi-automatic and automatic models. The first ones (4011, 5111) during operation use a constantly burning wick, ignited by a piezoelectric element. The second, with automatic ignition, runs on batteries. The gas is ignited by a spark supplied to the burner device.
Using modulation - gas instantaneous water heaters Neva and Neva Lux operate using hydraulic (5111, 5611) and electronic (6011,6014) changes in water heating power. There are models without automatic adjustment of combustion intensity.
The design of Neva and NevaLux geysers is constantly being modified and modified. New models are being produced, the design of which is adjusted taking into account the wishes of consumers.
The technical characteristics of water heaters manufactured by Baltgaz are described in detail in the following table:

This code means that the water temperature has exceeded the permissible value
It is strictly recommended to connect heating boilers through a stabilizer (for the boiler) or a UPS; this will save you from unnecessary costs for replacing the control board.
Checking the polarity in the plug-socket connection: turn the plug 90 degrees and insert it back into the socket or stabilizer.
Check grounding: the main cause of errors installed in apartments.
In the private sector, circuit testing is carried out with a device - a megger; when measuring resistance, R should show no more than 4 ohms.
The simplest testing of a pump is performed by turning its shaft manually and assessing the condition of the mechanical part based on how easily the shaft turns.
Low coolant pressure in the system: if the boiler pressure gauge needle leaves the green sector and turns to red), it is necessary to increase the pressure to the minimum threshold of 1 Bar
The make-up valve is located at the bottom of the heating installation, next to the connection pipe for the cold water pipe.
It opens counterclockwise until the characteristic noise of the incoming liquid appears; do not forget to close the tap in the reverse order, otherwise the pressure will creep into the reverse red zone and the relief valve will begin to operate (water will flow).
Leakage: easy to identify by walking around the house, looking at puddles on the floor
Focus on pipe connections, heating radiators, mounted appliances
The water supply tap in the system is closed: you need to check the position of the controls of the taps, valves on the main line and bypass. Most likely, the heating circuit pipe is blocked in some area.
The coarse filter on the main line is clogged: it gradually becomes clogged with sediment from the heating system, and if the mesh has not been washed for a long time, dirt can cause an error.
The pressure switch is faulty: the sensor is initially set to a value of 0.45 bar. and when the pressure in the heating circuit increases, its contacts close, a switch-on permission signal is sent to the board, a drop in pressure leads to a break in the circuit, and an error is generated - blocking the operation of the boiler in emergency mode.
The safety valve has failed.
Failures in the gas supply to the house: often the gas supply pressure on the main line decreases and the boiler does not return to operating mode. The check comes down to igniting all the burners on the stove at maximum mode. Flames with a characteristic shade will indicate the absence of problems with the fuel supply, and their intensity and stability will indicate the constancy of the pressure and its normal value.
You also need to check:
- The position of the shut-off valve controls: the gas supply valve to the house may have been accidentally turned off or the shut-off valve was activated during a power outage.
- Serviceability, condition of technical devices: meter, reducer (with autonomous gas supply), main filter, filling level of the tank (gas tank, cylinder group).
Resistance between pins 1 and 3 – 6.5; 1 and 4 – 7.4 (for SIT SIGMA 845048 block).
If there is a discrepancy, the gas valve is replaced (turn-to-turn short circuit). If R = ∞ – open circuit, R = 0 – short circuit.
The electronic board is faulty: a fault in the electronic circuit also causes an error to appear in the boiler.
Defects are identified by inspection for deformation, melting, breaks, condensation, etc.
The new board may not be configured correctly.
If the cause of equipment failure is the board, contact the service center indicating the alphanumeric marking of the node.
Typical faults
Boiler error codes can be found in the operating instructions
Any complex equipment fails after prolonged use. The main indicator of reliability is quick commissioning through repairs with the elimination of typical faults. A warranty card is issued for any heating equipment and installation work. Therefore, calling a technician during the warranty period will be free - the manufacturer’s warranty will cover equipment malfunctions, and the installer company will eliminate installation defects.
A list of major equipment errors can be found on a special display.
Error 01
In the Neva Lux boiler, this type of error means that the device cannot be ignited.
- Check valve opening and gas supply. If necessary, call the gas service.
- The gap between the spark plug and the burner should be 5 mm. Adjust.
- Isolate the breakdown site when the candle is broken.
- Clean the dirty spark plug.
- Ring the ignition transformer circuit.
Error 03
An uninsulated chimney allows condensation to accumulate, which impedes operation.
Accumulation of condensate in pipes causes error type 03.
- The chimney is clogged or its structure is damaged.
- Depressurization of the pressure switch tube or disruption of its electrical network.
- Fan failure.
Error 04
Error 4 indicates insufficient pressure in the heating circuit. This interferes with the functioning of the components and contributes to overheating of the boiler.
- Increase the pressure in the circuit.
- Remove the air lock using the air bleed valve.
- Check the pressure sensor.
- Clean the pump and inspect the connections.

The company's new product is the Turbo boiler
As the Lux models were used, both negative and positive consumer reviews accumulated. Over time, all the necessary adjustments resulted in the production of a separate series of heating equipment.
Neva Turbo boilers are, in fact, a modified version of the already familiar Lux modification, taking into account the shortcomings of previous versions. The models have the following technical characteristics:
- Closed combustion chamber - forced air supply is carried out using fans. Smoke removal occurs using a special device through a coaxial chimney.
Automation - gas double-circuit mounted boiler Neva Turbo, a station completely ready for operation. Heating control and safety are achieved using a multi-level system of sensors and valves. There is a self-diagnosis system that automatically performs tests and displays fault messages on the LCD display.
Controls: Simple push-button controls. Using a simple regulator, you can set the required temperature, provided that the programmer is installed, you can set operating conditions for several days or a week. A room thermostat is supplied as an additional package. The sensor sends a signal to turn off the heating when the room is heated to the required temperature.
Turbo boilers are energy-dependent. The boiler is powered by connecting to a regular 220 V mains voltage. For stable operation, you will need to install a UPS and a generator.
Ease of maintenance and operation
Regardless of the chosen model, installation of a mounted boiler is quick and without the need for additional costs. The manufacturer places the main emphasis on ease of installation and subsequent operation. Therefore, the company’s boilers, in fact, represent a station ready for operation.
It is enough to connect the installation to the heating and power supply system and start heating your house or apartment. In practice, provided the heating system is already ready, all work takes about 3-4 hours.
After installation, there is no need to worry about the safety of the station. The sequence of operation of the automation completely eliminates the possibility of gas leakage and the creation of an emergency situation, even if an unplanned power outage occurs.

The main differences between Neva boilers
Simple design and operation make it possible to distinguish Neva boilers among all domestic heating equipment. Today, in terms of their characteristics, boilers are in no way inferior to foreign equipment and have a more attractive price.
The Turbo modification provides economical gas consumption and, subject to proper operation, fully pays for itself within a few years.
Neva gas boilers: technical characteristics, range overview and maintenance
Currently, many people install gas boilers in their homes. These products are widely represented in heating equipment stores. Today we will talk about such devices from Neva.
Design features
Neva gas boilers are single-circuit or double-circuit equipment that has an open or closed combustion chamber. Each of these devices has a built-in thermostat. It controls the temperature of the coolant.
The operation of such units can be generated with a thermostat , which will make it possible to accurately set the temperature regime. The burner of this device has automatic equipment used to control the flame.
Such devices boast a multi-stage security system that increases the service life of heating equipment.
Each Neva boiler is equipped with a pressure gauge (a device for measuring gas and liquid pressure). Install it on the device panel. With a significant increase in temperature, the pressure in the system increases. Heating appliances from this company can operate stably even at low water and gas pressure.
These gas boilers have a screen with which you can set the required temperature. Thanks to the display, the operation of blocks and nodes is monitored. It comes with a special control panel. In one set with the device itself there is an expansion tank, a circulation pump and a detailed diagram that contains a complete description of how to install the device.
Other faults
If the device does not turn on:
- There is no power, contact the supply company.
- The fuse has burned out, you need to replace it, it is located on the board.
- A leak inside the boiler, which led to liquid getting onto the board and causing a short circuit. Dry the board on the battery or with a hairdryer and let it dry for two days.
Popping sounds during operation:
- Adjust gas pressure.
- Poor air flow in the room, clean the chimney duct, open the window or door while the boiler is operating.
- Accumulation of a large amount of soot in the burner group.
There is a smell of gas:
- If there is a gas leak, you must immediately contact the gas service.
- Low fluid pressure, contact water supply.
- If the heat exchanger is clogged, clean it using special chemicals.
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.
Air supply and flue gas removal (errors 6**)
The system for supplying air and removing flue gases generated during the operation of a gas boiler can be natural or forced. Therefore, some errors may not occur for different devices. But we'll look at them all.
Error No. 601. The draft thermostat is triggered when the contact is broken or the smoke exhaust thermostat is internally damaged. It is also possible that the air vent system is clogged.
Error No. 602. The same thing, only for VMC type combustion chambers.
Error No. 604. The Hall sensor is faulty (it needs to be replaced) or the speed of the fan blades is low (it needs to be cleaned or also replaced).
Error No. 607. The contacts of the controlling pneumatic relay were closed before the fan turned on. This detail confirms that there is sufficient draft before ignition. To eliminate early closure, you need to carefully remove the pneumatic relay and blow out its tubes, removing dirt or condensation. If this does not help, the part will have to be replaced.
The air relay is connected to the exhaust chamber with a silicone tube. Sometimes there is a condensate trap there. If the problem is with the pressure switch, then first you need to check the integrity of the tube
Error No. 610. Thermal fuse contacts are open. This part needs to be replaced.
Error No. 612. Same as error No. 604, but on early Ariston models.
Main technical characteristics and features of Neva company equipment
Please note that wall-mounted gas boilers on the market are available with open and closed combustion chambers. What does it mean? In the first case, combustion products are removed naturally, through the chimney to which the device is connected. The air required for normal gas combustion is taken from the room.
In the second case, the gas boiler is connected to a coaxial chimney, the design of which is made according to the “pipe-in-pipe” principle. Through the inner pipe, combustion products are forced out, 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 to heat the coolant, the second is designed to heat sanitary water.
Household appliances of this type are distinguished by a wide power range, which allows you to select a unit for installation in an autonomous heating system for a house of any size
When choosing a device, it is important to consider that 1 kW is needed to normally heat 10 m2. So, if a house, for example, has an area of 200 m2
in which there is a need for hot water supply, then for the system to operate stably, efficiently and economically, you will need to buy a Neva double-circuit gas boiler of any model with a capacity of 24 kW.
How to turn on the Neva column
Automatic water heaters turn on independently. When the water supply tap is opened, the ignition unit sends a signal to produce a spark. The gas supplied to the burner ignites. After closing the water consumption tap, the column turns off.
Semi-automatic instantaneous boilers are distinguished by the fact that a pilot burner is used for ignition. To bring the column into working condition, you need to light the wick. For this purpose, a piezoelectric element is provided in the internal device. After igniting the pilot burner, the water heater continues to operate in automatic mode.
You can adjust the Neva column using water flow and gas pressure regulators. If the device has a modulating burner, the consumer sets the heating temperature, after which the electronics changes the combustion intensity depending on the pressure in the pipeline and other operating parameters.
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.

Model range of boilers Neva Lux
The luxury series, well known to consumers, is divided into two categories:
- For heating an apartment or house, a wall-mounted single-circuit Neva boiler is best suited. Instead of a DHW circuit, you can install an indirect heating boiler. The modulation burner installed in such boilers, thanks to automatically changing combustion intensity, makes it possible to achieve high efficiency of the equipment. The 8618 single-circuit gas boiler attracts buyers with its low cost and simplicity of design, as well as the absence of complex energy-dependent automation.
- The double-circuit boiler 7218 luxury series from the Neva company has extremely positive reviews due to its practicality and efficiency. Modern automation allows you to accurately monitor the temperature of the coolant and water in the DHW circuit. In addition, some models provide additional outlets for the underfloor heating system. The installed automation is capable of controlling each circuit separately. The most popular models are 7218 and 8224.
Overview of the boiler line
Model 8224 Turbo is suitable for heating an apartment up to 250 sq. m.
m The Lux model line has been updated with a new Turbo modification. This is a separate series of equipment. It was made taking into account the advantages and disadvantages of the previous modification.
Widely used models:
- For heating an apartment or house, a single-circuit wall-mounted boiler is suitable. Instead of a water circuit, you can install an indirect heating boiler. The modulation burner allows you to effectively save fuel. The 8618 boiler is attractive due to its simplicity of design and low cost. It does not contain volatile, complex electronics. Compact dimensions allow installation in small spaces. The circulation pump in the boiler makes it possible to connect to existing heating systems. It is possible to connect an indirect heating boiler, a forced smoke removal fan, or a room thermostat.
- The 7218 and 8224 Lux series are very popular among dual-circuit models. Modern automation monitors the temperature in the hot water supply and at the same time energizes the heated floor outlets. To reduce heating costs, a separate thermostat is installed to monitor the room temperature - it turns on the boiler only when the set temperature drops. Neva Lux 7218 is suitable for heating an area of 180 sq.m. The bithermic heat exchanger reduces equipment costs while maintaining user-specific features. The efficiency is 90%. The device can be converted to liquefied gas. It has a closed combustion chamber. The coolant temperature is 30-85 degrees. An electronic safety unit with permanent flame monitoring constantly checks the burner.
- Neva Lux 8224 heats 250 sq. m. of residential premises. Water cooling of the combustion chamber doubles the operating life. The microprocessor maintains the temperature level of the working environment with an accuracy of 1 degree. A copper heat exchanger is used for the heating circuit; a stainless steel one is used for the hot water supply. The ability to connect a computer has been added to the control to simplify diagnostics and equipment configuration. The digital display displays self-diagnosis information with parameters and errors.
The operation of the boiler is based on the “set it and forget it” principle. Once you set the parameters, you don't have to worry even when you turn off the power. During a long business trip or trip, the equipment is set to minimum mode and saves gas. When the gas supply stops, the boiler switches to circulation mode and circulates water around the circuit, preventing it from freezing.
