How to light an electronic ignition device
Before turning on the column, it is necessary to ensure that there is an influx of fresh air in the room, since oxygen is burned during operation. All Neva devices are produced adjusted for a certain type and pressure of gas - natural G20, liquefied G30 with a corresponding pressure of 1.3 kPa and 2.9 kPa.
For example, let's consider how to light a Neva 4511 and Lux 5611 geyser with electronic ignition from LR20 batteries with a voltage of 1.5V (see the article in addition - why the Neva column does not light up). These devices have continuous hydraulic modulation of the flame. The front panel is equipped with a viewing window, gas and water adjustment knobs, and a digital display.
To turn on, install the batteries in the battery compartment, first make sure that the battery contacts of the battery compartment are not oxidized.
Open shut-off valves in front of the machine. Then turn the toggle switches to the minimum position. If ignition occurs for the first time, or after a long period of inactivity of the device, air must be removed from the system. This requires opening and closing the valve with water several times to continue ignition, since spark discharges last about seven seconds. After turning on, being careful not to get close to the viewing window, you need to make sure that the flame burns even, blue, without the yellow edges that appear if the burner is clogged.
The jet is adjusted using a knob, if the water supply has a low pressure, it should be set to the minimum position, while at the outlet of the device you will get a small, medium amount of water. If the pressure inside the line is high and you need to a large number of water, the regulator should be set to the maximum value. If, at a low pressure, set the maximum value, then the column will go out, it can also go out if the tap is opened to a small flow. To make it light up again, you need to turn the regulator to the minimum position or increase the jet pressure.
You can adjust the temperature with the gas adjustment knob - the maximum position increases its flow rate and the temperature of the outlet jet, the minimum - vice versa. In addition, you can adjust the temperature of the outlet jet by changing its flow rate with a hot water valve - opening it more, the temperature will decrease, screwing it on, it will increase.
But it should be remembered that the temperature obtained is limited by the power of the device, with a high flow rate, especially in winter, it may have insufficient temperature.
When the jet adjustment toggle switch is set to the minimum position, and the gas regulator to the maximum position, the heat exchanger will overheat, the column will go out, as the overheating sensor will work. To turn on the device again, you need to close the hot water tap, then open it again. Use the toggle switches to reduce the gas flow or increase the water flow. Overheating of the heat exchanger leads to the formation of scale, noise during operation. This reduces the productivity of the device, reduces the output flow, therefore it is not recommended to dilute the hot jet with a cold one, as the service life of the device decreases. From user experience, you should not set the temperature above 60 degrees.
To turn off the unit, it is enough to close the valve, make sure that the main burner is extinguished. If it is turned off for a long time, close the shut-off gas and water valves.
How to light a column with piezo ignition
Models of water heaters Neva 3208, 3212.4011 differ from models 4511.5611 in the type of ignition using a piezoelectric element.
To turn on the Neva 4011, you need to open the gas and water shut-off valves that are located in front of the device. Set the gas regulator knob (on the front panel) to the "Ignition" position, drown it to the limit. Holding with one hand, with the other hand press the piezo ignition button, which is located at the bottom of the device. At the same time, it should appear spark discharge between the spark plug and the pilot burner, which ignites the gas supplied to it.
The holding time is about 20 seconds, until the pilot burner lights up. Then the handle can be lowered. During initial start-up, bleed air from gas system. To do this, while holding the toggle switch, press and release the piezo ignition button several times.
Next, you need to switch the regulator to the “Turn on the main burner” mode. In this case, only the pilot burner is lit, the main one is ignited after the hot water valve is opened. If the tap is open, and the main one is not on, it is necessary to adjust the pressure with a water adjustment, or open it more strongly. You can turn off the column by turning off the water.
The inclusion of columns 3212, 3208 also begins by opening the shut-off valves. Next, fix the “Ignition” toggle switch opposite the risks, press the button of the solenoid valve. While holding the button (about 60 seconds), press the electric ignition button several times (or light it with a match if there is no button, as is the case with some models 3208) until a flame appears on the pilot burner.
After releasing the solenoid valve button, move the toggle switch all the way to the right, to the “Big flame” position, the pilot burner is working, the main burner has not yet ignited. When the tap is opened, the main one lights up. To turn off the device, you need to close the tap, turn the knob on the front panel counterclockwise until it stops, close the valves of the gas pipeline, water supply.
Video on ignition of the gas column Neva 3208:
The BaltGaz company produces: geysers Neva (Neva) and Neva Lux (NevaLux), shut-off and control valves, chimneys and all accessories necessary for connection. Water heaters operate in flow mode, designed for simultaneous connection of 1-3 points of water intake. Thanks to its compact dimensions, it is easy to install even in small spaces used for the boiler room.
The device and principle of operation of the columns Neva and NevaLux
The BaltGas line includes several flow-through gas boilers, differing in the principle of operation and features of the internal structure. All manufactured equipment can be divided into several groups:- Type of ignition - there are semi-automatic and automatic models. The first (4011, 5111) during operation use a constantly burning wick, ignited by a piezoelectric element. The second, with automatic ignition, are battery operated. The gas is ignited by a spark applied to the burner.
- 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 the intensity of combustion.

How to install a column Neva
When connecting the Neva gas water heater, you must follow the manufacturer's recommendations, which are detailed in the operating instructions. Mistakes made during installation will void the warranty.Installation of the Neva column is carried out exclusively by qualified personnel (representatives of the service center or gas service) who have access to work and the appropriate license.
When connecting the column, follow a few basic recommendations: 
The service life of the Neva gas flow boiler largely depends on compliance with the installation and operation rules, as well as regular maintenance. The period of use of the water heater is from 8-12 years.
How to turn on the Neva column
Automatic water heaters turn on by themselves. When the water supply tap is opened, the ignition unit gives a signal to produce a spark. The gas supplied to the burner ignites. After closing the water tap, the column is turned off.Semi-automatic flow boilers are distinguished by the fact that an ignition burner is used for ignition. To bring the column to a working state, you need to light the wick. To this end, in internal arrangement a piezoelectric element is provided. After ignition of 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 is provided with a modulating burner, the consumer sets the heating temperature, after which the electronics changes the intensity of combustion depending on the pressure in the pipeline and other operating parameters.

How to clean the Neva column at home
In order for the Neva boiler to continue to work properly, every 2-3 years it is necessary to flush the heat exchanger, eliminating accumulated scale and soot. It will be possible to clean the Neva gas column at home even with poor water quality. Maintenance is carried out in several stages:- Remove the radiator- to pull out the heat exchanger of the Neva column, unscrew the casing, disconnect the water and gas. Dismantle the smoke exhaust unit. Pull out the radiator.
- Rinse and clean the heat exchanger- remove soot from the plates with a stiff brush and soapy water. To remove scale, the inner cavity of the coil is washed with special "chemistry" or citric acid.
The gas water heater NEVA 3208 is convenient, simple and reliable. Despite the venerable age of most of the operated specimens, they quite regularly cope with their duties of heating water. But sometimes you want to clarify something in the instruction manual. And here comes the problem.
The original instructions are most often lost, and downloading the operating instructions on the Internet is Neva-3208 impossible. More modern columns Neva series 4000, 5000, Neva Lux 6000, boilers Neva Lux series 8000 - please, but there are no instructions for Neva 3208.
In the search, only fraudulent sites that require a cell phone number come across, but even there there is no instruction - only the name of the file. This is easy to check by trying to find a file on such a site with a name that obviously does not exist - for example, " qwerrasdfgfgh-$%# [email protected]$ ". He will find it, and even say that it has been downloaded several thousand times! I hope that you do not fall for such tricks and do not enter your phone number on suspicious sites.

5. DEVICE AND OPERATION OF THE DEVICE
5.1. Device device
5.1.1. The apparatus (Fig. 1) of the wall-mounted type has a rectangular shape formed by a removable lining 7.
5.1.2. All main elements of the device are mounted on a frame. On the front side of the cladding are: handle 2 for controlling the gas valve, button 3 for turning on the solenoid valve, viewing window 8 for observing the flame of the pilot and main burners.
5.1.3. The apparatus (Fig. 2) consists of a combustion chamber 1 (which includes a frame 3, a gas exhaust device 4 and a heat exchanger 2), a water-gas burner unit 5 (consisting of a main burner 6, an ignition burner 7, a gas cock 9, a water regulator 10, a valve electromagnetic 11) and tube 8, designed to turn off the water heater in the absence of draft in the chimney.
NOTE: Due to the fact that OJSC continues to work on further improvement of the design of the device, the purchased device may not fully match the description or image in the “Operation Manual” in individual elements.
5.2. Description of the device
5.2.1. The gas through pipe 4 (Fig. 1) enters the solenoid valve 11 (Fig. 2), the switch button 3 (Fig. 1) of which is located to the right of the switch handle gas cock.
5.2.2. When the solenoid valve button is pressed and open” (to the “Ignition” position) (Fig. 3), the tap gas flows to the pilot burner. The thermocouple, heated by the ignition burner flame, transmits the EMF to the valve solenoid, which automatically holds the valve disc open and provides gas access to the gas cock.
5.2.3. When turning handle 2 (Fig. 1) clockwise, the gas valve 9 (Fig. 2) performs the sequence of turning on the pilot burner to the “Ignition” position (see Fig. 3), gas supply to the main burner in the “Apparatus on” position ( see Fig. 3) and regulates the amount of gas supplied to the main burner within the "High flame" - "Small flame" positions (see Fig. 3) to obtain the desired water temperature. In this case, the main burner lights up only when water flows through the device (when a hot water tap is opened).
5.2.4 Turning off the apparatus is done by turning the control knob counterclockwise to the stop, while the main and pilot burners are instantly extinguished. The electromagnetic plug valve will remain open until the thermocouple cools down (10...15 s).
5.2.5. To ensure smooth ignition of the main burner, the water regulator is provided with an ignition retarder, which acts as a throttle when water flows out of the supra-membrane cavity and slows down the upward movement of the membrane, and, consequently, the ignition speed of the main burner.
The device is equipped with safety devices that provide:
- gas access to the main burner only in the presence of a pilot flame and water flow
- shutting off the gas valve to the main burner in case the pilot burner goes out or the water flow stops,
- shutdown of the main and pilot burners in the absence of draft in the chimney.

A gas water heater is a water heater that has excellent technical characteristics. Appliances this type of steel has become more in demand recently, however, in order to purchase and install a structure with your own hands, you will need to figure out how the device works and what advantages and disadvantages it has. The peculiarity of such columns is that they are needed in those houses and apartments where there is no hot water supply or it is often turned off.
Feature: Neva 4511
The gas column device is a device for heating water, and gas is required for its operation. The main criterion for choosing such installations is, of course, the characteristics of the product, as well as its cost and quality.
If you choose these settings for technical specifications, then you need to pay attention to such points as:
- Ignition type;
- Chimney type;
- Power;
- Safety;
- Dimensions;
- Additional functionality.
If we consider the quality of products, then it is worth considering the entire model range and it will be possible to find out that a huge number of such structures are on sale. most sought after and best model- this is Neva 4511, which has an unrealistic number of positive reviews, and also has all quality certificates and compliance with GOST standard.
Column Neva and its ignition
As already mentioned, there are an incredible number of models of gas water heaters and these can be: 3208, 4510, 4513, 3212, 5513, 3010 and more. The principle of operation and the connection diagram are almost the same. It is worth noting that the operation of a product called Neva requires ignition of the column, which means ignition of the gas.
There is equipment that differs in this criterion, and there are products with:
- Manual ignition;
- Piezo ignition;
- Electronic ignition;
- Microturbine ignition.
If the column is ignited manually, then this is an old model, since modern columns are automatic or Lux transit devices, which are not difficult to handle. The type of piezo ignition is similar to piezo electric stoves, in which to turn on the unit and ignite the gas, just press 1 button. This option can be found in modern devices, as it is very convenient and most importantly, it is safe to use products in residential premises. Electronic products are considered the most popular, but more expensive, but this does not affect their demand.
They have qualities such as:
- Reliability;
- Profitability;
- Ease of use.
Getting a spark is created in the same way as in cars, using a small battery, but batteries are most often used.
The Neva 4511 column is a model in which just such an ignition is installed.
There are also microturbine types of ignition, in which current is generated by means of a hydrodynamic generator, which is controlled by a water flow. In terms of cost, they are superior to all previous models, including HSV, Nomi, but they are the safest and provide good service.
Instructions for use of the geyser Neva 4511
Studying a document such as an instruction manual is the best opportunity to learn what actions are needed to avoid a problem in the operation of the device, and also not to harm yourself and the equipment. In other words, you need to read the rules safe operation. First of all, it is important to remember that gas water heaters are high-risk equipment and the likelihood of an accident is very high, which can harm sensors, in particular, an ionization sensor and human health. This element is responsible for shutting off the gas supply if the burner goes out.
In addition, each element that consists of geyser :
- Thermal sensors must be in good order, since they work at the moment when it stops, the ionization sensor is functioning.
- Thanks to the heating sensor, you can monitor the temperature in the flow heater, as well as regulate the temperature of all equipment.
- A water pressure sensor is required for the main task of the device, in particular to turn on and off the gas supply if automatic water intake occurs.
- It is imperative to monitor the health of the sensor that controls the temperature difference in order to stop the operation of the burner in time and avoid the boiler from exploding.
It is strictly forbidden to use a column without a gas and water pressure sensor. It is with its help that you can control the flow of water and gas into the cavity of the column. If the water tap is open and it is turned off, the gas will not be supplied automatically, which is facilitated by the safety valve.
Description of the Neva geyser
Why do many make decisions such as purchasing equipment such as a gas water heater? Regardless of whether the installation will be old or new, it must be: high-quality, wear-resistant and correctly installed. In addition, you need to pay attention to how much power the structure has and how quickly it can heat water to heat the room. Naturally, if the house or apartment is large, then you need a device that will be able to heat it.
speakers gas type divided by power:
- 17-20 kW (small columns);
- 20-26 kW (medium speakers);
- 26-28 kW (large speakers).
With regards to the Neva column, in particular model 4511, it has a power consumption of 21 kW, however, it is capable of producing up to 11 liters per minute. To approximately determine liters per minute, it is enough to pay attention to the instruction manual. It is worth noting that the Neva 4511 model is perfect for two drawdown points, and if you need to connect to more points, then a higher power installation is required.
Specifications: geyser Neva 3208
The service life of such a design as the Neva Lux is quite long, however, in order for it to serve properly and not require repairs, as malfunctions will appear, it is necessary that the owner knows how to use the product.
Typically, this equipment does not require:
- Traction adjustment;
- Elimination of fistulas due to which the tank flows;
- Clean the radiator.
It is worth noting that the heater will not work if there is low pressure water in the pipes, and it is completely difficult to find the gas source from which the device operates, and therefore these moments can be called negative sides designs.
A column called Neva 4511 can function even if the pressure is 0.2 atmospheres, but it is not advisable to use it for a long time.
If such an electric gas water heater does not work well, then the heat exchanger may need to be replaced. The heater has the peculiarity that you do not need to contact a service center to change this part.
How does a geyser work
The task of this type of water heater is to quickly respond to the opening of a tap with hot water, which turns on the burner. For detailed description the principle of operation of such a device, it is enough to pay attention to the sequence of actions.
Namely:
- Initially, it is required to set fire to the igniter, which is located in the cavity of the viewing window directed towards the burner.
- After the tap is opened, water begins to flow into the DHW system, which increases the pressure in the pipes.
- Thanks to the water unit, the membrane is activated and the stem moves, which is connected to the valve installed on the gas pipe.
- Since the membrane of the water unit presses on the valve, it opens and the fuel supply to the main burner begins, which is ignited automatically from the igniter or from the electrode, depending on the design model.
- It is possible to adjust the flame manually by means of a special tap, which is displayed on the front panel.
- Water enters the heat exchanger cavity in the gas column, after which heating begins in the coil, which goes around the copper casing.
Turning on the device is not too difficult, and if configuration is required, then simply use the instruction manual. As soon as the water has reached the consumer and the tap is closed, after the membrane tap is closed, the stem is pulled on the frog, the gas supply valve is closed, and the burner goes out.
Gas column repair Neva
Experts do not recommend doing maintenance yourself, especially if you need to not only configure the equipment, but also disassemble it. Flowing geysers are needed so that the water does not stagnate, but flows, and the fact that it flows would be enough for consumer needs.
In this device, the solenoid valve often fails.
When the tap is opened, you can hear the click of the machine, which contributes to the ignition of the burner, but the gas does not flow. It is through the solenoid valve that gas is supplied to the burner. It is not difficult to replace it, just like heat exchangers. The diameter of the valve is standard, and the connection is not difficult to make. To purchase a spare part, you just need to know the model of your geyser or take an old faulty valve with you.
To remove and install equipment for heating water, it is best to contact specialists with extensive experience who can not only carry out all necessary actions but also provide a guarantee.
For the installation of a geyser, a special permit is required, since it is necessary to carry out power supply from a gas pipe, and this is possible only with special equipment. After that, you need to register the geyser as an object of gas consumption, especially if you are connecting to a central highway.
With regards to operation, it is advisable not to heat it to the maximum level, as this will only accelerate the process of salt and scale formation on the cavity of the heating element. It is important to take into account the hardness of the water used and choose special agent that can soften it, which will significantly extend the life of all equipment.
Centralized hot water supply is certainly a convenient thing. But often, moving into a rented or purchased secondary market housing an apartment, we are faced with an outlandish unit - an old gas water heater. How is it safe to use?
A geyser, or, as it is officially called, a flowing gas water heater, appeared in our country with the beginning of mass housing construction in the 50s of the twentieth century. It was the installation of gas water heaters in apartments that made it possible to quickly solve the problem of hot water supply without the construction of expensive heating plants and pipeline networks.
How to determine the type of gas column?
First of all, let's define the terminology - we will call the old geyser, the design of which provides for a constantly burning ignition wick. The wick is lit with a match or, in more modern models, a spark from a manual piezoelectric igniter.
The gas water heaters installed in Stalinka and Khrushchev apartments overwhelmingly belong to two varieties - KGI-56 and similar in design L-1, L-2, L-3, GVA-1, GVA-3, early models of VPG. It is easy to distinguish them from each other by the control knobs.
The KGI-56 column (gas column of the Iskra plant, design of 1956) was widely used in the construction of multi-storey buildings in the 50-60s of the last century. It has a rectangular slightly rounded body with an oval opening for ignition and two levers in the lower part of the body - the ignition burner switch-on lever and the main burner power control lever. In later modifications, a solenoid gas valve button is also installed on the front panel.
Columns of the L (Leningrad), GVA (automatic gas water heater), VPG (flowing gas water heater) series are structurally similar and have one rotary knob in the center and (optionally) an electromagnetic gas valve button.
HSV columns have become perhaps the most common in Russia and were produced in huge batches under various names (Neva 3208, Neva 3210, Neva 3212, Neva 3216, Darina 3010 and others).
The era of mass installation of gas water heaters in our country was short-lived - after 20-25 years, almost all new buildings were connected to hot water supply networks. Speakers left hallmark"Stalinok" and "Khrushchev". But their owners do not complain - this is Russia. And while the “lucky ones” with centralized hot water supply heat water in a basin on the stove every summer for two or three weeks, they calmly use hot water. Yes, and the gas column is much cheaper than hot water from pipes.
And therefore, probably, the inhabitants of new buildings pass horror stories to each other about an unknown and terrible device - a gas water heater. And it breaks in a day, and it takes a long time to kindle it, and it is dangerous to use it. Is it really?
Is it safe to use an old gas water heater?
A person who is accustomed to centralized hot water supply usually judges the safety of a geyser based on rumors and speculation of friends and acquaintances. Often these people have a gas water heater, especially old design, and did not see in the eye. Hence, terrible legends about almost daily explosions of gas water heaters multiply. It comes to the point that some families, living on rented apartment and having a completely serviceable apparatus, they heat hot water in a basin on the stove.
All these horror stories are greatly exaggerated. Any geyser, even if it was made half a century ago, has safety devices in its design. These devices include a water regulator, a flame sensor, and a draft sensor.
The main burner burns with a non-smoking blue or light yellow flame;
When the taps are closed at the taps or on the inlet pipe, the column goes out immediately, without delay;
The column allows you to adjust the temperature of hot water from barely warm to scalding hot;
The column does not turn off spontaneously during use.
If any of the above is not true, then the column must repair or, if repair is not profitable, replace with a new one.
Please note that 5-10 seconds after turning on the column from the tap, a few seconds can go very hot water, gradually replaced by water of the set temperature. Out of habit, you can get burned, but this is not a malfunction, but a design feature.
Is it possible to use a faulty geyser?
There can only be one answer to this question: absolutely not! And do not be convinced by people who successfully operate a geyser with minor or not very minor malfunctions.
The point here is this. Finding an old gas water heater from the 50s-70s in full working order is quite difficult. Most often, the flame control system turns out to be out of order - it and the new one did not differ in good reliability. Therefore, very often the gas valves in the columns are stuck open. Even the gas workers themselves did this, as it was tight with spare parts. It is easy to determine this - the gas valve button is not pressed or is pressed very easily. With some care, such a column works without problems.
Sometimes the water regulator is faulty. The author himself used a column with such a problem for several years. I had to open the water, and then light the column manually. When turning off, it was necessary to close the gas supply to the main burner and only then turn off the water. It was customary, and even then more than once, due to forgetfulness, it turned out to boil the column.
But for a person who is accustomed to using centralized hot water supply, this is unacceptable! Habits developed over the years are very difficult to change. You can bet on anything that on the first day you will boil a column with a faulty water regulator. Therefore, the device must be in perfect working order.
