The OJSC Gazapparat company, founded in 1945, produces gas equipment under the well-known brand “Neva” (NEVA). The main product of this company is high-quality geysers "Neva Lux" for heating water. In this production line There are many models that differ in power and size. The Neva Lux geyser is most often used in dachas or apartments where a constant supply is required hot water.
Such water heating equipment is made of a metal body, a gas burner, and a heat exchanger made of copper.
The body is covered with enamel. The burner heats up copper heat exchanger, through which running water passes. The performance of the column depends on the size of the heat exchanger.
"Neva Lux" can be used to heat hard water. All of them are equipped with traction sensors and a safety system that prevents emergency situations.
The gas appliance begins instantly heating the water when the tap is turned on and ends when it is closed. The temperature of the water coming from the water heater, thanks to the built-in automation, does not change even with low pressure.
Let's look at the most popular models of the Neva Lux line:
Neva Lux 5513
This “comfort” class model is equipped with automatic ignition of the burner. This greatly simplifies the operation of the device. In the absence of draft or when the burner goes out automated system immediately cuts off the flow of gas into the unit.
In addition, the Neva Lux 5513 geyser is adapted to low water pressure up to 0.10 bar, which is also suitable for our water supply conditions. Its rated power is 25 kW. When the water is heated to + 25 degrees C, productivity hot water is 13 liters/min. The device weighs 13 kg.
Neva Lux 5514
This model has a similar structure as the Neva Lux 5513, but is distinguished by greater productivity and heat exchanger power. It is available in two colors: white and metallic.
Equipped with a flame control system that turns off geyser when the fire goes out. The power of the Neva Lux 5514 comfort class dispenser is 28 kW, and the hot water output is 14 liters/min. It also weighs 13 kg.
Neva Lux 5611
Model “5611” is an analogue of “5111”, but unlike the second one, it is additionally equipped with a self-ignition function. Innovative safety systems and control sensors prevent gas from entering the building, and a closed, water-cooled combustion chamber protects the building from fire. The disadvantage of the model is the mechanical regulation of water temperature. For example, the “6011” model has special temperature control buttons running water. Despite this, the “5611” model costs significantly less.
The minimum water pressure in the pipes, which is allowed for normal operation of the gas apparatus, is 0.15 bar. The column has a production power of 21 kW and productivity warm water 11 liters/min. (at 25 degrees C.) The model weighs 9.5 kg. The Neva Lux 5611 geyser is equipped with an electronic display on the body, which makes it easier to set up the water heating system.
In addition to comfort-class geysers, the OJSC Gazapparat company has been producing a line of premium-class devices since 2004. They are distinguished by advanced systems for monitoring and adjusting water temperature. The most popular models of this class are considered to be “Neva Lux 6011” and “Neva Lux 6014”. They differ in performance and, accordingly, in the size of the heat exchanger. Let's consider each model separately.
Neva Lux 6011
Technical characteristics are similar to the “5611” model. At the same time, Neva Lux 6011, as indicated above, is equipped with a push-button system with an electronic display instead of mechanical control.
This geyser is quite easy to operate. Has an automatic flame ignition system. Available in two colors (white and steel). The power of the gas heater is 21 kW. At a water temperature of +25 degrees. S. has a capacity of 11 liters/min.
The column is adapted to work with low water pressure in pipes (up to 0.15 bar). The device weighs 9.5 kg. Has small sizes 565x290x221 mm.
Neva Lux 6014
This model is the most powerful and advanced device. It is equipped with an electronic display, combustion sensors, a security system, water heating controls, as well as automatic system ignition of the burner when the tap is turned on.
The power of the Neva Lux 6014 geyser is 28 kW, which allows you to supply two points with hot water at once. The device produces 14 liters of water per minute and weighs 13 kg.
Thus, we can conclude that the most powerful and productive Neva Lux geysers are models “6014” and “5514”. The first one is more expensive, but it is more advanced.

How to light a device with electronic ignition
Before turning on the column, you need to make sure that there is an influx in the room fresh air, since oxygen is burned during operation. All Neva devices are produced adjusted to certain type and gas pressure - 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 using 1.5V LR20 batteries (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 a long period of inactivity of the 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 amount 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. 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 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; at high flow rates, especially in winter, it 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 for a long time, you should close the gas and water shut-off valves.
How to light a speaker with piezo ignition
You can find out complete information on the selection, operation and maintenance of geysers (instantaneous water heaters) from all manufacturers if you go.
In addition to specific information on the site, you can also study specific problems from other people on this topic who have already purchased a gas water heater or instantaneous water heater and thus avoid them. You will find a regularly updated list of such problems and their solutions.
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, 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, a spark discharge should appear 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 the hot water valve opens. 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.
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 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, and close the gas and water supply valves.

If you want to receive complete information on this problem, as well as find out other important nuances about the gas water heater from your manufacturer, .
But we also have information on this problem and more, which you will not find anywhere, first of all, because it is asked by specific people who could not get more support and advice anywhere (which they themselves tell us). And secondly, their problems are so complex that sometimes our expert Alexander Kholodov takes 10 days or more to deal with people.
And now EVERY question from the user and the answer to it, in order to avoid financial costs as a result of improper operation or repair of the flow-through heater. And here it doesn’t matter which manufacturer’s device is involved in the issue. The only thing that matters is the unique situation as a result of which this issue arose, because as one good saying goes: “forewarned is forearmed.”
