How to light a device with electronic ignition

Before turning on the column, you need to make sure that there is a flow of fresh air in the room, since oxygen is burned during operation. All Neva devices are produced adjusted to a specific 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 look at how to light a gas water heater Neva 4511 and Lux ​​5611 with electronic ignition from LR20 batteries with a voltage of 1.5 V (additionally, see the article - why the Neva water heater does not light up). These devices have continuous hydraulic flame modulation. The front panel is equipped with an observation window, gas and water adjustment knobs, and a digital display.

To turn it on, you must 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 in front of the device. Next, turn the toggle switches to the minimum position. If ignition occurs for the first time, or after long downtime device, air should be removed from the system. To do this, you need to open and close the water valve several times to continue ignition, since spark discharges last about seven seconds. After switching on, being careful not to get close to the inspection window, you need to make sure that the flame burns evenly, blue, without yellow edges that appear if the burner is clogged.

The jet is adjusted using a knob; if the water supply has low pressure, it should be set to the minimum position, and you will get a small, medium amount of water at the outlet of the device. If the pressure inside the line is high, and you need a large number of water, the regulator should be set to the maximum value. If you set the maximum value at low pressure, the column will go out, and it can also go out if the tap is opened to a small flow. In order for it to light up again, you need to turn the regulator to the minimum position or increase the jet pressure.

You can adjust the temperature using the gas control knob - the maximum position increases its flow rate and the temperature of the outlet stream, the minimum position - vice versa. In addition, you can adjust the temperature of the outgoing stream by changing its flow rate with the hot water valve - opening it more, the temperature will decrease, screwing it down, it will increase.

But it should be remembered that the resulting temperature is limited by the power of the device, with high consumption, especially in winter, may have insufficient temperature.

When you set the jet adjustment toggle switch to the minimum position and the gas regulator to the maximum, the heat exchanger will overheat and the column will go out, as the overheating sensor will trip. To turn the device on again, you need to close the hot water tap, then open it again. Use toggle switches to reduce gas flow or increase water flow. Overheating of the heat exchanger leads to scale formation and noise during operation. This reduces the productivity of the device and reduces the output flow, so it is not recommended to dilute a hot stream with a cold one, since the service life of the device is reduced. Based on user experience, the temperature should not be set above 60 degrees.

To turn off the unit, just close the tap and make sure that the main burner has gone out. If it turns off at long time, you should close the gas and water shut-off valves.

How to light a speaker 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, water supply shut-off valves, which are located in front of the device. Set the gas regulator knob (on the front panel) to the “Ignition” position, push it down to the limit. 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 it should appear spark discharge between the spark plug and the pilot burner, which ignites the gas entering it.

The holding time is about 20 seconds until the pilot burner lights up. The handle can then be lowered. When starting up for the first time, remove any air from the gas system. To do this, you need to hold the toggle switch, press and release the piezo ignition button several times.

Next, you need to switch the regulator to the “Turning on the main burner” mode. In this case, only the pilot burner lights up, the main burner lights up after opening the hot water valve. If the tap is open, but the main one is not on, you need to adjust the pressure using the water adjustment, or open it more. You can turn off the column by turning off the water.

The switching on of columns 3212, 3208 also begins by opening the shut-off valves. Next, fix the “Ignition” toggle switch opposite the risk, press the button 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 3208 models) until a flame appears on the pilot burner.

Having released 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 light comes on. 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 and water supply.

The NEVA 3208 geyser is convenient, simple and reliable. Despite the venerable age of most of the units in use, they cope with their duties of heating water quite well. But sometimes you want to clarify something in the instruction manual. And this is where the problem arises.

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.

The search only turns up fraudulent sites that require a number cell phone, but even there there are no instructions - just the name of the file. This can be easily checked by trying to find on such a site a file with a obviously non-existent name - for example, “ qwerrasdfgfgh-$%#$@$" He will find it, and even say that it has been downloaded several thousand times! I hope that you don’t fall for such tricks and don’t enter your phone number on suspicious sites. You can find the operating instructions for the Neva-3208 gas water heater here.

5. DEVICE AND OPERATION

5.1. Device structure

5.1.1. The wall-mounted device (Fig. 1) has rectangular shape, formed by removable lining 7.

5.1.2. All main elements of the device are mounted on the frame. On the front side of the cladding there are: handle 2 for controlling the gas tap, button 3 for turning on the solenoid valve, viewing window 8 for observing the flame of the ignition 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 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 to further improve the design of the device, the purchased device may not completely match the individual elements with a description or image in the “Operation Manual”.

5.2. Description of the device operation

5.2.1. Gas through pipe 4 (Fig. 1) enters the solenoid valve 11 (Fig. 2), the activation button 3 (Fig. 1) is located to the right of the switch handle gas tap.

5.2.2. When you press the solenoid valve button and open” (to the “Ignition” position) (Fig. 3), the gas flows to the pilot burner. The thermocouple, heated by the pilot burner flame, transmits the EMF to the valve electromagnet, which automatically holds the valve plate open and provides gas access to the gas valve.

5.2.3. When turning handle 2 (Fig. 1) clockwise, gas valve 9 (Fig. 2) carries out the sequence of turning on the ignition burner to the “Ignition” position (see Fig. 3), supplying gas 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 “Large 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 the hot water tap is opened).

5.2.4 The device is turned off by turning the control knob counterclockwise until it stops, and the main and ignition 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, the water regulator is equipped with an ignition retarder, which acts as a throttle when water flows out of the above-membrane cavity and slows down the upward movement of the membrane, and therefore 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
• closing the gas valve to the main burner in cases where the pilot burner goes out or the water flow stops,
• turning off the main and ignition burners in the absence of draft in the chimney.

Centralized hot water supply is certainly a convenient thing. But often, when moving into an apartment rented or purchased on the secondary housing market, we are faced with an outlandish unit - an old gas water heater. How can it be used safely?

A gas water heater, or, as it is officially called, a flow-through 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 geysers in apartments that made it possible to quickly solve the problem with hot water supply without the construction of expensive heating plants and pipeline networks.

How to determine the type of geyser?

First of all, let's define the terminology - we will call the old one a gas water heater, the design of which includes a constantly burning ignition wick. The wick is lit with a match or, more commonly, modern models, a spark from a manual piezoelectric igniter.

The geysers installed in Stalinka and Khrushchev buildings overwhelmingly 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 their control knobs.

Column KGI-56 (column gas plant"Iskra", designed in 1956) was widely used in construction multi-storey buildings in the 50-60s of the last century. It has a rectangular, slightly rounded body with an oval hole for ignition and two levers at the bottom of the body - the pilot burner activation lever and the main burner power control lever. In later versions, a solenoid gas valve button is also installed on the front panel.

Dispensers of the L (Leningrad), GVA (automatic gas water heater), VPG (instantaneous gas water heater) series are structurally similar and have one rotary knob in the center and (optional) a solenoid gas valve button.

HSV columns became, perhaps, the most common in Russia and were produced in huge quantities under different names(Neva 3208, Neva 3210, Neva 3212, Neva 3216, Darina 3010 and others).

The era of mass installation of geysers in our country was short-lived - after 20-25 years, almost all new buildings were connected to hot water supply networks. The speakers remain distinctive feature"Stalin" and "Khrushchev". But their owners don’t complain - this is Russia. And while the “lucky ones” with a centralized hot water supply heat the water in a basin on the stove every summer for two or three weeks, they calmly use hot water. Yes and it works geyser significantly cheaper than hot water from pipes.

And that’s probably why residents of new buildings tell each other horror stories about an unknown and terrible device - a gas water heater. And it breaks down every other day, and it takes a long time to light it, and it’s dangerous to use it. Is it really?

Is it safe to use an old gas water heater?

A person accustomed to centralized hot water supply usually judges the safety of a gas water heater based on rumors and speculation of friends and acquaintances. Often these people have never even seen a gas water heater, especially an older one. Hence, terrible legends about almost daily explosions of gas water pumps are multiplying. It gets 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. Such 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 you close the taps at the water collection 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 barely warm to scalding hot;

The speaker does not turn off spontaneously during use.

If any of the above is not true, then the column needs 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, several seconds can take a very long time. hot water, gradually giving way to water set temperature. If you're not used to it, you can get burned, but this is not a malfunction, but a design feature.

Is it possible to use a faulty gas water heater?

There can only be one answer to this question: absolutely not! And don’t let people who successfully operate a gas water heater with minor or not-so-minor defects convince you.

The point here is this. Finding an old gas water heater from the 50s-70s in perfect working order is quite difficult. Most often, it is the flame control system that fails - even the new one was not very reliable. Therefore, all the time gas valves the columns are stuck open. Even the gas workers themselves did this, since spare parts were tight. This is easy to determine - 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 this problem for several years. I had to turn on 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. This was common, and more than once I ended up boiling the column due to forgetfulness.

But for a person accustomed to using centralized hot water supply, this is unacceptable! Habits developed over the years are very difficult to change. You can bet 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.

A geyser is a water heater that has excellent technical characteristics. Appliances This type has become more in demand recently, however, in order to purchase and install a structure with your own hands, you will need to understand how the device works and what advantages and disadvantages it has. The peculiarity of such speakers is that they are needed in those houses and apartments where there is no hot water supply or where it is often turned off.

Characteristics: 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 select these settings according to 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 whole the lineup and it will be possible to find out that a huge number of such structures are going on sale. The most popular and best model– this is Neva 4511, which has an unrealistic number positive feedback, and also has all quality certificates and compliance with GOST standards.

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 more. The operating principle and connection diagram are almost the same. It is worth noting that the process of operating a product called Neva requires igniting 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 it is an old model, since modern speakers 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, you just need to press 1 button. This option can be found in modern devices, since it is very convenient and most importantly safe to use the products in residential areas. Electronic products are considered the most popular, but more expensive, but this does not affect their demand in any way.

They have qualities such as:

• Reliability;
• Economical;
• Ease of use.

The 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 through a hydrodynamic generator, which is controlled by water flow. In cost they exceed all previous models, including HSV, Nomi, but they are the safest and provide good service.

Operating instructions for the gas water heater Neva 4511

Studying a document such as an instruction manual is best opportunity learn what actions are needed to avoid problems with the device, and also not to harm yourself and the equipment. In other words, you need to familiarize yourself with the rules safe operation. First of all, it is important to remember that geysers are equipment increased danger and the probability of an accident is very high, which can harm the sensors, in particular the ionization sensor and human health. This item is responsible for shutting off the gas supply if the burner goes out.

In addition, every element that makes up the gas water heater must be in good working order.:

1. Thermal sensors must be in good working order, since they operate the moment the ionization sensor stops functioning.
2. Thanks to the heating sensor, you can monitor the temperature in flow heater, as well as regulate the temperature of all equipment.
3. 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.
4. It is imperative to monitor the serviceability of the sensor that controls the temperature difference in order to stop the operation of the burner in time and avoid a boiler explosion.

It is strictly forbidden to use the 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 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 people make decisions such as purchasing equipment such as gas water heating column? 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 much power the design 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 gas type divided by power:

• 17-20 kW (small speakers);
• 20-26 kW (medium speakers);
• 26-28 kW (large speakers).

As for the Neva column, in particular model 4511, it has a consumption power of 21 kW, however, it is capable of producing up to 11 liters per minute. To approximately determine liters per minute, just pay attention to the operating instructions. It is worth noting that the Neva 4511 model is perfect for two water points, and if you need to connect to more points, then a higher power installation is required.

Technical characteristics: 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, the owner must be able to use the product.

Typically this equipment is not required:

• Traction adjustment;
• Elimination of fistulas due to which the tank leaks;
• Clean the radiator.

It is worth noting that the heater will not work if there is water with low pressure in the pipes, and it is completely difficult to find a source of gas from which the device operates, and therefore these points can be called negative sides designs.

A column called Neva 4511 can function even at a pressure of 0.2 atmospheres, but it is not advisable to use it for a long time.

If such an electric geyser does not work well, then the heat exchanger may need to be replaced. The heater has the peculiarity that to change this part you do not need to contact a service center.

How does a gas water heater work?

The task of this type of water heater is to quickly respond to the opening of a hot water tap, as a result of which the burner turns on. For detailed description The principle of operation of such a device is enough to pay attention to the sequence of actions.

Namely:

1. Initially, you need to ignite the igniter, which is located in the cavity of the inspection window directed towards the burner.
2. After the tap is opened, DHW system Water begins to flow, which increases the pressure in the pipes.
3. Thanks to the water unit, the membrane is activated and the rod moves, which is connected to the valve installed on the gas pipe.
4. 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.
5. It is possible to adjust the flame manually using a special tap, which is displayed on the front panel.
6. Water enters the cavity of the heat exchanger in the gas column, after which heating begins in the coil, which runs around the copper casing.

Turning on the device is not too difficult, and if configuration is required, it is enough to simply use the operating instructions. As soon as the water reaches the consumer and the tap is closed, after the membrane tap is closed, the rod on the frog is pulled back, the gas supply valve is closed, and the burner goes out.

Repair of geyser Neva

Experts do not recommend carrying out maintenance yourself, especially if you need to not only set up the equipment, but also disassemble it. Flow-through geysers are needed so that 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 you open the tap, you can hear the click of the machine, which helps ignite the burner, but 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 purchase a spare part, you just need to know the model of your gas water heater or take with you an old faulty valve.

To remove and install water heating equipment, it is best to contact specialists with extensive experience who can not only carry out all the necessary actions, but also provide a guarantee.

To install a gas water heater, a special permit is required, since it is necessary to power it from gas pipe, and this is only possible if there is special equipment. After this, you need to register the geyser as an object of gas consumption, especially if you are connecting to the central pipeline.

As for operation, it is advisable not to heat it up to maximum level, since this will only speed up the process of formation of salt and scale on the cavity of the heating element. It is important to take into account the hardness of the water used and select special remedy, which can soften it, which will significantly extend the service life of all equipment.

The BaltGaz company produces: gas water heaters Neva (Neva) and Neva Lux (NevaLux), shut-off and control valves, chimneys and all the components necessary for connection. Water heaters operate in flow-through mode and are designed for simultaneous connection of 1-3 water supply points. Thanks to its compact dimensions, it is easy to install even in small spaces, used as a boiler room.

Design and principle of operation of Neva and NevaLux speakers

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:

• Ignition type - 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:

How to install the Neva column

When connected gas water heater Neva is required to follow the manufacturer's recommendations, detailed in the operating instructions. Mistakes made during installation will result in 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 the work and the appropriate license.

When connecting speakers, follow several basic recommendations:

The service life of a Neva gas instantaneous boiler largely depends on compliance with 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 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. To this end, in internal structure a piezoelectric element is provided. 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.

Neva speakers - malfunctions and their elimination

Water heaters Russian company BaltGas mostly operate without failures. 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.

How to clean the Neva column at home

In order for the Neva boiler to continue to function properly, the heat exchanger must be flushed every 2-3 years, removing accumulated scale and soot. You can clean the Neva gas water heater at home even if the water quality is poor. Maintenance is carried out in several stages:

• Removing the radiator- to remove the heat exchanger of the Neva column, unscrew the casing, disconnect the water and gas. The smoke exhaust unit is dismantled. They take out the radiator.
• Rinse 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 a special “chemistry” or citric acid.

In case of serious contamination, the column should be serviced in a specialized service center. Washing is carried out using pumping equipment.
