Geyser neva 3216 instruction. Gas water heaters Neva and Neva Lux (Neva and NevaLux). Is it safe to use an old gas water heater
The geyser NEVA 3208 is convenient, simple and reliable. Despite the venerable age of most of the exploited specimens, they quite regularly cope with their responsibilities for heating water. But sometimes you want to clarify something in the instruction manual. And this is where the problem comes in.
The original manual is most often lost, but the user manual is downloaded from the Internet. Neva-3208 impossible. More modern dispensers Neva 4000, 5000 series, Neva Lux 6000, boilers Neva Lux 8000 series - please, but there are no instructions for Neva 3208.
The search comes across only fraudulent sites requiring a cell phone number, but even there there is no instruction - one file name. It is easy to check this by trying to find a file on such a site with a deliberately non-existent name - 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. And the instruction manual for the Neva-3208 geyser can be found here.

5. STRUCTURE AND OPERATION OF THE APPARATUS
5.1. Device device
5.1.1. The apparatus (Fig. 1) of the wall type has a rectangular shape, formed by a removable cladding 7.
5.1.2. All the main elements of the apparatus are mounted on a frame. On the front side of the cladding are located: handle 2 for controlling the gas valve, button 3 for switching 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 outlet 4 and a heat exchanger 2), a water-gas burner unit 5 (consisting of a main burner 6, a pilot burner 7, a gas valve 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 device design, the purchased device may not completely coincide in some elements with the description or image in the "Operation Manual".
5.2. Description of the device
5.2.1. Gas through the branch 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 gas valve switch knob.
5.2.2. When you press the solenoid valve button and open "(to the" Ignition "position) (Fig. 3) the valve, the gas flows to the ignition burner. The thermocouple, heated by the flame of the pilot burner, transmits EMF to the valve solenoid, which automatically keeps the valve disc open and provides gas access to the gas cock.
5.2.3. When knob 2 (Fig. 1) is turned clockwise, gas valve 9 (Fig. 2) carries out the sequence of turning on the ignition burner to the "Ignition" position (see Fig. 3), gas supply to the main burner in the "Appliance on" position ( see fig. 3) and adjusts the amount of gas flowing to the main burner within the "high flame" - "low 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 the hot water tap is opened).
5.2.4 The device is turned off by turning the control knob counterclockwise to the stop, while the main and pilot burners are instantly extinguished. The valve of the electromagnetic plug will remain open until the thermocouple cools down (10 ... 15 s).
5.2.5. To ensure smooth ignition of the main burner, an ignition retarder is provided in the water regulator, which works as a choke when water flows out of the supra-membrane cavity and slows down the movement of the membrane upward, and, consequently, the ignition speed of the main burner.
The device is equipped with safety devices that ensure:
- gas access to the main burner only with a pilot flame and water flow
- shutting off the gas valve to the main burner in case of extinguishing of the pilot burner or cessation of water flow,
- shutdown of the main and pilot burners in the absence of draft in the chimney.

How to install the Neva column
When connecting a Neva gas water heater, it is required to follow the manufacturer's recommendations detailed in the operating instructions. Errors during installation will result in a denial of warranty service.Installation of the Neva column is carried out exclusively by qualified personnel (representatives of the service center or gas service) who have permission to perform work and the corresponding license.
When connecting a speaker, several basic recommendations are followed: 
The service life of the Neva gas flow boiler largely depends on compliance with the rules for installation and operation, 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 independently. 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 turns off.Semi-automatic flow-through boilers are distinguished by the fact that an ignition burner is used for ignition. To bring the column into working condition, you need to ignite the wick. For this purpose, a piezoelectric element is provided in the internal device. 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 a modulation burner is provided in the device, 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.
Columns Neva - malfunctions and their elimination
The water heaters of the Russian company BaltGaz generally operate without interruptions. In automatic speakers, you have to change the batteries every six months. Every 4-5 years, the membrane (rubber gasket) of the water unit fails. To repair the water unit, use a repair kit for the column, costing 80-200 rubles.Below are two tables. The first describes common error codes, their decoding and troubleshooting methods. The second table shows breakdowns and repair methods, without reference to digital signals.

How to clean the Neva column at home
In order for the Neva boiler to continue working properly, every 2-3 years it is required to flush the heat exchanger, removing the accumulated scale and soot. It will be possible to clean the Neva gas water heater 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. Take out the radiator.
- Flush and clean the heat exchanger- soot is removed from the plates using a stiff brush and soap solution. To remove scale, the internal cavity of the coil is washed with special "chemistry" or citric acid.
A gas water heater is a water heater that has excellent technical characteristics. Household appliances of this type have 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 where it is often turned off.
Feature: Neva 4511
The geyser 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 installations for technical characteristics, 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. The most popular and best model is the Neva 4511, which has an unrealistic number of positive reviews, and also has all the quality certificates and compliance with the GOST standard.
Column Neva and its ignition
As already mentioned, there are an incredible number of models of geysers, and these can be: 3208, 4510, 4513, 3212, 5513, 3010 and not only. The principle of operation and the connection diagram are almost the same. It is worth noting that the process of operating a product called Neva requires lighting the column, which means igniting the gas.
There is equipment that differs according to 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 speakers are automatic devices or Lux transit, which is not difficult to cope with. 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, since it is very convenient and most importantly safe to use products in residential premises. Electronic products are considered the most in demand, but more expensive, but this does not affect their demand in any way.
They have such qualities as:
- Reliability;
- Profitability;
- Ease of use.
The spark is generated in the same way as in cars, by means of a small battery, however, batteries are most often used.
Column Neva 4511 is a model in which just such a ignition is installed.
There are also microturbine types of ignition, in which current is generated by a hydrodynamic generator, which is controlled by a water flow. In terms of cost, they surpass all previous models, including the HSV, Nomi, but they are the safest and provide good service.
Operating instructions for the gas water heater Neva 4511
Studying such a document as the operating instructions is the best opportunity to learn what actions are needed to avoid problems in the operation of the device, as well as not to harm yourself and the equipment. In other words, you need to familiarize yourself with the rules for safe operation. First of all, it is important to remember that gas water heaters are equipment of increased danger and the likelihood of an accident is very high, which can harm the sensors, in particular, the 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 makes up the gas water heater must be in good working order.:
- The temperature sensors must be in good working order, since they are triggered at the moment when the ionization sensor stops 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 for turning on and off the gas supply if there is an automatic water intake.
- It is imperative to monitor the health of the sensor that controls the temperature difference in order to stop the burner operation in time and avoid the boiler explosion.
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 column cavity. If the tap with water is open and it is turned off, then the gas will not be supplied automatically, which is facilitated by the safety valve.
Description of the geyser Neva
Why do so many make decisions such as purchasing equipment such as a gas water heater? Regardless of whether the installation is old or new, it must be of high quality, wear-resistant and correctly installed. In addition, you need to pay attention to how powerful 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.
Columns of gas type are divided by power:
- 17-20 kW (small speakers);
- 20-26 kW (mid-range speakers);
- 26-28 kW (large speakers).
As for the Neva column, in particular the 4511 model, 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 tapping points, and if you need to connect to a larger number of points, then an installation with a higher power is required.
Specifications: gas water heater Neva 3208
The service life of such a structure as Neva Lux is long enough, however, in order for it to serve properly, and no repairs are required, since malfunctions will appear, it is necessary for the owner to know 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 a gas source from which the device operates, and therefore these moments can be called negative aspects of the structure.
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 the service center to change this part.
How does a gas water heater work
The task of this type of water heater is to respond quickly to the opening of the hot water tap, as a result of which the burner turns on. For a detailed description of 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 ignite the igniter, which is located in the cavity of the viewing window directed towards the burner.
- After the tap is open, water begins to flow in the DHW system, which increases the pressure in the pipes.
- Thanks to the water unit, the membrane is triggered 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 supply of fuel 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 cavity of the heat exchanger in the gas column, after which heating begins in the coil, which goes around the copper casing.
It is not too difficult to turn on the device, and if adjustment is required, then it is enough just to use the instruction manual. As soon as the water has entered the consumer and the tap is closed, after the membrane tap is closed, the stem is pulled back on the frog, the gas supply valve is closed, and the burner goes out.
Repair of the gas column Neva
Experts do not recommend that you carry out maintenance yourself, especially if you need to not only configure the equipment, but also disassemble it. Flowing gas water heaters 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 fails quite often.
When you open the tap, you can hear the machine click, which contributes to the ignition of the burner, but no gas is supplied. It is through the solenoid valve that gas is supplied to the burner. Replacing it is not difficult, just like the heat exchangers. The diameter of the valve is standard, and the connection is not difficult. To purchase a spare part, you just need to know the model of your gas water heater 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 the necessary actions, but also provide a guarantee.
For the installation of a gas water heater, a special permit is required, since it is necessary to supply power from a gas pipe, and this is possible only with special equipment. After that, you need to register the gas water heater as an object of gas consumption, especially if it is connected to the central highway.
With regard to operation, it is advisable not to heat it to the maximum level, since 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 select a special agent that can soften it, which will significantly extend the service life of all equipment.
Centralized hot water supply is, of course, a convenient thing. But often, moving into an apartment rented or purchased on the secondary housing market, we come across an outlandish unit - an old gas water heater. How is it safe to use it?
A gas water heater 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 with hot water supply without building expensive heating plants and pipelines.
How to determine the type of gas water heater?
First of all, let's define the terminology - we will call the old one a gas water heater, the design of which provides for a constantly burning ignition wick. The wick is ignited with a match or, in more modern models, with a spark from a hand-held piezoelectric igniter.
The overwhelming majority of gas water heaters installed in "stalinkas" and "Khrushchevs" belong to two varieties - KGI-56 and similar in design L-1, L-2, L-3, GVA-1, GVA-3, early VPG models. It is easy to distinguish them from each other by the control knobs.
Column KGI-56 (gas column of the Iskra plant, construction in 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 - a lever for starting the ignition burner and a lever for controlling the power of the main burner. In later versions, the front panel also has a gas solenoid valve button.
Columns of the L series (Leningrad), GVA (automatic gas water heater), VPG (gas flowing water heater) are structurally similar and have one rotary knob in the center and (optionally) a button for an electromagnetic gas valve.
HPG columns became, 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. Columns remained the hallmark of the "Stalin" and "Khrushchev" buildings. But their owners do not complain - this is Russia. And while the "lucky ones" with centralized hot water supply every summer for two or three weeks heat water in a basin on the stove, they calmly use hot water. And the gas water heater costs much cheaper than hot water from the pipes.
And that is why, probably, the residents of new buildings pass on horror stories to each other about an unknown and terrible apparatus - a gas water heater. And it breaks down every other 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 gas water heater according to rumors and speculations of friends and acquaintances. Often these people have not even seen a gas water heater, especially of an old design. Hence, terrible legends are multiplied about almost daily explosions of gas columns. It comes to the point that some families, living in a rented apartment and having a completely serviceable apparatus, heat hot water in a basin on the stove.
All these horror stories are greatly exaggerated. Any gas water heater, even if it was made half a century ago, has safety devices in its design. Such devices include a water regulator, a flame detector and a draft sensor.
The main burner burns with a non-smoky blue or light yellow flame;
When the taps are closed at the water points or on the inlet pipe, the column goes out immediately, without delay;
The column allows you to regulate the temperature of hot water from lukewarm to scalding hot;
The column does not turn off spontaneously during use.
If any of the above is not met, then the column needs to renovate or, if the repair is not profitable, replace with a new one.
Please note that 5-10 seconds after turning on the column, very hot water can flow from the tap for several seconds, gradually changing with water at the set temperature. You can get burned out of habit, but this is not a malfunction, but a design feature.
Can I use a faulty gas water heater?
There can be only one answer to this question: absolutely not! And do not be convinced by people who successfully operate a gas water heater with minor or not very minor malfunctions.
The point is this. It is quite difficult to find an old gas water heater from the 50-70s in complete serviceability. Most often, the flame control system turns out to be out of order - even the new one was not distinguished by good reliability. Therefore, quite often the gas valves in the columns are stuck open. Even the gas workers themselves did this, since it was tight with spare parts. It is easy to determine this - the button of the gas valve is not pressed, or it 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 this 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 accustomed to using centralized hot water supply, this is unacceptable! Habits developed over the years are not easy to change. You can argue on anything that on the very first day you will boil a column with a faulty water regulator. Therefore, the device must be in full working order.

How to ignite an electronic ignition device
Before turning on the column, it is necessary to ensure that there is an inflow of fresh air in the room, since oxygen is burned during operation. All Neva devices are manufactured regulated for a certain type and pressure of gas - natural G20, liquefied G30 with the corresponding pressure of 1.3 kPa and 2.9 kPa.
For example, consider how to light a Neva 4511 and Lux 5611 gas column with electronic ignition from 1.5V LR20 batteries (see also the article on why the Neva column does not light up). These devices have continuous hydraulic flame modulation. 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 contacts of the batteries and the battery compartment are not oxidized.
Open the shut-off valves upstream of the device. Then turn the tumblers to the minimum position. If the ignition occurs for the first time, or after a long period of inactivity of the device, it is necessary to remove air from the system. To do this, it is required to open and close the valve with water several times to continue ignition, since spark discharges last about seven seconds. After switching 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 with a handle, if the water supply system has a low pressure, it should be set to the minimum position, while at the outlet of the device you will receive a small, medium amount of water. If the pressure inside the line is high and you need a lot of water, the regulator should be set to the maximum value. If, at a low head, you set the maximum value, then the column will go out, it can also go out if the valve is opened for a small flow. In order for it to light up again, you need to turn the regulator to the minimum position or increase the pressure of the jet.
You can adjust the temperature with the gas control knob - the maximum position increases its flow rate and temperature of the outlet stream, the minimum - vice versa. In addition, the temperature of the outgoing jet can be adjusted by changing its flow rate with a hot water valve - opening it more strongly, the temperature will decrease, screwing it on, it will increase.
But it should be remembered that the resulting temperature is limited by the power of the device, with a high flow rate, especially in winter, it may have an insufficient temperature.
When the jet control 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 is triggered. To turn on the device again, you need to close the hot water tap, then open it again. Reduce gas consumption or increase water consumption using toggle switches. Overheating of the heat exchanger leads to the formation of scale, noise during operation. This reduces the productivity of the device, reduces the outflow flow; therefore, it is not recommended to dilute the hot stream with a cold one, as the service life of the device decreases. From user experience, the temperature should not be set higher than 60 degrees.
To turn off the unit, it is enough to close the tap, make sure that the main burner has gone out. If it turns off for a long time, close the shut-off gas, water valve.
How to light a piezo column
Models of water heaters Neva 3208, 3212,4011 differ from models 4511,5611 in the type of ignition with the help of a piezoelectric element.
To turn on the Neva 4011, you need to open the gas, water shut-off taps, which 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. While holding it with one hand, press the piezo ignition button with the other hand, which is located at the bottom of the device. In this case, a spark discharge should appear between the ignition plug and the ignition burner, which ignites the gas supplied to it.
The holding time is about 20 seconds, until the ignition burner ignites. Then the handle can be lowered. At initial start-up, bleed air from the gas system. To do this, while holding the toggle switch, press several times, release the piezo ignition button.
Next, you need to put the regulator in the mode "Turning on the main burner". In this case, only the pilot burner burns, the main burner ignites after opening the hot water valve. If the tap is open, and the main one does not light up, it is necessary to adjust the pressure with water regulation, 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 (for 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 3208 models) until a flame appears on the ignition 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 been ignited. When you open the tap, the main one lights up. To turn off the device, you need to close the tap, turn the handle on the front panel counterclockwise until it stops, close the valves of the gas pipeline, water supply.
