Gas dispenser Astra instruction. Geyser astra - malfunctions and their elimination. Repair of a geyser brand "Astra"

Unfortunately, the domestic housing and communal services system still leaves much to be desired and does not fully provide the consumer, so people have to rely on their own strength and install additional devices in heating and water supply systems. For example, purchase gas water heaters.

Peculiarities

JSC PKO "Teploobmennik", which produces gas water heaters "Astra", has existed for more than 50 years. Perhaps even our grandparents used his products. True, then this company was called differently.

The column "Astra" is designed to work with hot water. Only gas is used as fuel.

The device of such a column is quite simple and includes several components. The main part - a rectangular case - is mounted on the wall. On the front panel there are windows for ignition and combustion control, a power button, gas supply adjustment knobs. At the bottom there are fittings for supplying gas, hot and cold water, and at the top there is a chimney outlet.

All main nodes are located inside the case and fixed on the rear panel. It also has mounting holes. The combustion chamber is made of high quality refractory material, which has a long service life. The conciseness of execution is an advantage in the model market and provides the manufacturer with a high demand for their products.

The principle of operation is as follows: for gas to enter the gas block and the igniter, it is necessary to turn the pilot burner knob to the left and turn on the device by pressing the button - the burner will turn on sequentially. The temperature of the hot water at the outlet is set by the position of the control knobs. Turning from right to left increases the gas supply, thereby increasing the temperature of the water, and from left to right, on the contrary, it decreases.

According to the functionality, the components of the column are conditionally divided into water and gas parts. On the market, you can purchase repair kits and spare parts for each node separately, as well as the whole node.

The technical characteristics of Astra speakers make it easy to compete with other manufacturers. The main plus is the power of the device: for some models it equals and even exceeds 20 kW. A large combustion chamber and relatively low gas consumption distinguish this brand.

Of course, each model has its own nuances in the characteristics, but you can derive general values. For example, the hot water supply is approximately 10-12 l / min, the outlet water temperature range is 35-60 degrees, the operating pressure range is 0.5-6 bar.

The manufacturer also thought about the safety of their products. If the burner goes out, the water supply will stop.

Any model comes with a passport and an instruction manual, which details the rules of operation and safe operation, as well as a schematic diagram of the device.

Kinds

Currently, there are many geysers with unusual colors on the market. Consumers sometimes make the mistake of choosing color over performance. The Astra geyser does not seek to stand out due to its appearance, but relies on performance, has its own model range.

Model 8910-00.02

has a high power - up to 21 kW and a capacity of 12 l / min. Dimensions - 700x372x230 mm. The chimney has a diameter of 120 mm. Gas consumption per hour is 2.3 cubic meters. m. Ignition occurs manually.

Open type combustion chamber. Traction is easy to check. The gas connection pipe is 3⁄4 inches, the water pipes are 1⁄2 inches. The weight of the device is 15 kg.

Model 8910-08.02

has a slightly lower power (up to 18 kW) and productivity (10 l / min). However, fuel consumption is also lower - 2 cubic meters. m/h The weight of the unit is 14.7 kg. The rest of the device is very similar to the previous model. Ignition is also done manually

Model 8910-15

It has one fundamental difference - this system is with electronic ignition of the burner, which is very convenient. Now there is no need to worry about the availability of matches.

The power of the unit reaches 20 kW, the productivity is 10 liters of hot water per minute. Gas consumption is 2 cubic meters. m/h The column weight is 13.9 kg. The chimney diameter is 135 mm.

Model 8910-16

It is also equipped with an electronic automatic burner ignition system. This automatic device is a champion in power (up to 24 kW). The unit heats water at a rate of 12 liters per minute. Gas consumption - 2.3 cubic meters. m/hour. The weight of the device is 14.7 kg.

It is worth noting that spare parts for Astra speakers can be easily found at reasonable prices.

How to use?

The purchase has been made, and the connection has been made by the employees of the relevant service. To turn on the column, first of all, you need to check the draft by attaching a strip of paper (2-5 cm wide and 20 cm long) to the side holes on the case. If from a distance of 15 cm the paper is attracted to the holes, then everything is in order.

Then you need to open the taps - first the gas valve, then the water valve. After that, you need to act in accordance with the type of model. For devices with manual ignition, turn the pilot burner control knob to the left to the "Open" position. Then you need to light a match and bring it closer to the igniter located on the front panel of the device, while simultaneously pressing and holding the button of the solenoid valve.

The holding time of the button can be different and range from 3 to 60 seconds. You can set a specific duration of pressing for your device empirically.

After the manipulations done, you should slowly open the hot water, turn the gas supply adjustment knob to the main burner, setting the desired position with a certain outlet temperature. If everything is done correctly, the main burner will light up.

For models with electronic ignition, the switching on procedure is even simpler: you need to turn the taps of the gas pipeline and water supply in front of the device, and then just turn on the hot water - the column will start itself.

Adjustment is made by two handles. The gas flow control knob affects the outlet temperature, and the water flow control knob changes the water flow accordingly.

To turn off the device with manual ignition, first move the handles of the main burner, and then the pilot burner to the right to the “Closed” position. Then make sure both burners are off. Now you can close the hot water tap and, finally, the general gas pipeline tap.

For automatic models, it is enough to close the taps.

From the reviews on Astra gas water heaters, we can conclude that the units are quite reliable, easy to operate and repair. Breakdowns are rare and replacement parts are easy to find on the market. Ease of operation is very popular with the older generation, which does not pursue newfangled functionality. And the price looks very attractive compared to foreign counterparts. At the same time, a modest but nice design allows you to fit such a device into any interior.

Malfunctions and methods for their elimination

Despite the proven reliability of the equipment, breakdowns still happen.

The wick goes out. In this case, it is necessary to check the draft on the side of the device, if necessary, clean the chimney from combustion products. If the fault persists, then it may be in the electrical part. It is necessary to investigate the contacts of the electrical circuit with the help of special equipment and eliminate the violation.
Pilot and main burners do not light up. In this case, it is necessary to check whether the gas supply valve is in the correct position. It is also worth paying attention to the thermocouple fitting - when loosened, it should be tightened. It may be necessary to replace a water line diaphragm that is torn or stretched. The igniter nozzle is sometimes clogged - in this case, cleaning is necessary. It may be necessary to adjust the position of the thermocouple sensor so that it is bathed by the flame of the pilot burner. Another simple reason is that the inlet water pressure is below the operating range. If all of the above is not suitable, then the malfunction may be in the solenoid valve.

This element must be replaced by a specialist.

No outlet water pressure. It is necessary to check the pressure of the incoming cold water. Also a common cause is the accumulation of scale on the filters. This is where cleaning is required. It is recommended to entrust the removal of scale in the heat exchanger tubes to a specialist.
Weak main burner, because of which the water does not heat up to the desired temperature. This means that the gas filters and nozzles on the main burner are clogged - you need to clean them of debris.
Dripping water. In this case, you can try to replace the gaskets at the joints. But if the heat exchanger is worn out - corrosion and cracks have formed on it - either sealing the heat exchanger or buying a new one will be required. It is worth noting that applying solder to the leak site gives a temporary effect, and sooner or later it will be necessary to replace the element.
When you turn on the water, you hear the pop of the main burner. This is because the gas pressure is low, or the plug holes and pilot nozzle are clogged.

Main characteristics

Geysers of the Astra series are distinguished by their simplicity of design and reasonable price. They are produced in Russia. The company has established itself in the market on the positive side.

Geysers are installed to heat water. To set up the unit after purchase, just read the instructions. The speakers in this series have large
combustion chambers. The consumption of natural gas will depend on the model of the device. In general, it is moderate.

The column draft and pressure can be adjusted. The highest temperature is 60°-65°C. The thermostat is located at the bottom.

The regulator is located under the central fitting. The products of combustion are regularly removed.

The unit is safe to operate.

Troubleshooting

Astra geysers may have any malfunctions. Let's take a look at how to fix them.

If there is a breakdown of the device, then first you need to turn off the gas supply. You can remove the column from the wall, or you can not remove it. It will be enough to remove its front part. To do this, unscrew the side bolts with a screwdriver.

Geysers have good burners. Most often, the economizer breaks down. It needs to be checked first.

Unscrew the two screws located on the edges of the device. Check contacts. They may not perform well due to contamination. If the contacts do not work, they must be replaced. After that, the economizer should work or it will have to be replaced.

Try to unscrew everything carefully, without touching the pressure measurement fittings.

If the gas column does not light up, then there may be no draft in the ventilation passage. Turn off the unit and bring a burning match to the chimney. The flame must go into it.

Get your repair tools ready. You can remove scale with ordinary vinegar.

In the Astra column, the hydraulic group may break. It must be disconnected and inspect the valves. They must hold on tight. For small shifts, the parts must be replaced. When purchasing such parts, be sure to indicate the model of the geyser.

This is a general troubleshooting scheme for Astra gas water heaters. Watch the video of disassembly and assembly of the geyser.

Why you should choose Astra gas water heaters: reviews

Among the main advantages of the equipment described in the article, consumers distinguish:

lack of extra functionality;
reliability;
the ability to easily configure the operation of the equipment;
high performance;
simple device;
ease of operation.

The equipment, according to consumers, is maintainable. All spare parts can be found in service workshops. Yes, and the column itself is quite cheap. Customers especially like the large combustion chambers, so the power of some models reaches 20 kW.

Traction adjustment for model 8910 is carried out independently. The thermostat in this embodiment is located below. The smoke exhaust track is wide enough, but the column regulator is located under the central fitting. The construction frame, according to property owners who have purchased such equipment for themselves, is very strong, so it can withstand any load.

The power supply has a protection system. Using special screws, you can easily adjust the fitting. The Astra geyser, the instruction manual for which is supplied in the kit, has, according to consumers, economical fuel consumption. The design has a high-quality pressure regulator. Traction can be checked very simply. Removal of combustion products occurs quickly. In matters of safety, the column outperforms other models.

Repair of a geyser brand "Astra"

Repair of the gas column "Astra" begins with shutting off the gas. The column may or may not be removed. The front part is dismantled with a screwdriver, but first you need to unscrew the bolts located on the sides. The first thing to check is the economizer, it is located behind the electrode. Removing the latter will be quite difficult. It is fixed with 4 bolts. Do not touch the heat exchanger.

When you repair individual components, it is important not to touch the fitting, it is used to measure pressure. If this part is damaged, then you will have to change the head. In order to remove the economizer, it is necessary to unscrew only two side bolts. The consumer may well carry out repairs with his own hands. The Astra geyser has contacts in the design that are often contaminated. If they have become unusable, then they need to be replaced. If the economizer does not work after replacement, then it will also have to be changed. These malfunctions are one of the main ones for Astra speakers.

If you encounter a problem when the Astra geyser does not light up, then this may indicate a lack of draft in the ventilation passage. It is very easy to check the tension. The geyser is turned off, and a burning match should be brought to the chimney outlet. If the flame is drawn into the chimney, then everything is in order - you can connect the column. Otherwise, the chimney should be cleaned. However, it is better to entrust this matter to a special master.

The Astra geyser, the malfunctions of which you should consider when operating this equipment, sometimes goes out immediately after ignition. In this case, the supply of cold water to the column should be adjusted. Do not try to dilute hot and cold water, this can cause the flame to die out.

Spare parts for gas water heater brand "Astra"

If you purchased the Astra 8910 gas water heater, spare parts for it may be needed during operation. You need to know what their value is. For example, a water unit will cost 1,600 rubles. The gas part costs 1,500 rubles. The magnetic stopper has a lower price - 205 rubles. The membrane costs 25 rubles. The repair kit for the water part costs 155 rubles, and the adjusting unit - 55 rubles.

Conclusion

If you still do not know whether it is worth buying an Astra gas water heater, then you should consider its features in more detail. For example, the copper heat exchanger in all models has an increased wall thickness. This ensures good heat transfer from heated gases to water, which allows saving. For more convenient operation, the manufacturer has equipped the design with a display with which you can determine the temperature of the heated water.

To understand how to properly use a gas column, you should know its structure and principle of operation. Regardless of the manufacturer and model, the water heater also consists of six main parts: a casing, an exhaust gas collector, a heat exchanger, a burner, a gas fitting, a hydraulic fitting and an ignition device.

On the casing there are water pressure and flame level regulators, power and ignition buttons (if the device uses piezo ignition) and a display. The case closes the main components of the water heater and gives it a beautiful appearance.

The exhaust manifold is on top. A chimney is connected to it with the help of a pipe.

In a turbocharged column with a closed combustion chamber, the manifold is lower and equipped with a fan. These are all Bosch models with the WTD marking (for example, Therm 4000 S WTD 15 AM E), Neva Turbo, Neva Lux 8224, Neva-Transit HSV 10 EMT. Oasis and Astra columns come only with an open combustion chamber.

The heat exchanger is the main and most expensive part of the device. Here, heat is exchanged from the flame to the water. It consists of a shell and pipes through which a stream of hot air passes. Expensive heat exchangers are made of copper without impurities, which can be seen from the uniform color of the metal.

The burner is located under the heat exchanger. It is designed to distribute the flow of gas. The gas entering the column enters the burner, where it is split into several streams. This expands the flame and allows the heat exchanger and water to heat up quickly.

The gas valve of the water heater controls the on and off of the gas. It is connected to hydraulic fittings. In the old-style Neva and Astra columns, the water-gas system is located vertically - there is a gas valve on top. In the new models of columns Neva 5611, 4511 (read how to use columns of the Neva Trademark), Oasis is horizontal, the hydraulic fittings are located on the right.

The ignition device is located near the burner. It consists of two electrodes, when electricity is applied to them, a spark appears. It can be semi-automatic, which needs to be ignited with a button that is placed on the front side of the column. These are all Bosch models with the letter “P” at the end of the marking, for example WR 10-2P.

Also, the ignition can be automatic due to the installed batteries or connection to the mains. Installed in most new devices.

The electrical circuit of gas water heaters includes the following elements: batteries or power supply, control unit, screen, protection devices, ignition and flame control electrodes.

The batteries or power supply are connected to the control unit. From it there are wires to sensors for draft and overheating of water, a screen and electrodes.

If a piezo ignition is used in the column, then an igniter ignition button is additionally present.

In the video below, an overview of the device and other everyday nuances of the Vaillant geyser:

Principle of operation

When the faucet is opened, water flows into the water regulator. At the same time, pressure is created in it, from which the rubber membrane bends. It moves the stem, which in turn opens the gas valve in the gas valve. Then the water goes through the pipes of the heat exchanger to the faucet.

The gas enters the burner and is ignited by an igniter or a spark between the electrodes. The flame heats the heat exchanger and the water passing through it.

Terms of use

In a number of models of water heaters on the front side of the case there is a power button that you need to press. If it is not there, then most likely the column is already ready to go.

If you have a semi-automatic water heater with piezo ignition, then, first of all, you need to light the igniter. To do this, press the corresponding button on the case.

Columns with electric ignition turn on automatically when you open a tap with water. When the faucet is closed, the flame will automatically go out.

In order to properly use the gas column, it is important to follow a number of operating rules:

It is undesirable to heat the water too much - this leads to rapid wear of the device. Modern columns allow you to heat water up to 70 degrees. It is recommended to set the water heater to 35-40 degrees, which is enough for domestic use.
It is not recommended to mix cold tap water with hot tap water. This causes the pressure to drop and the heater to go out. You need to set a comfortable temperature in advance.
From time to time, preventive work should be carried out - checking the traction force, changing water filters, cleaning the chimney and burner from soot.

Answers for the maintenance and repair of geysers Astra VPG

Question: The igniter on the Astra gas column does not light up. With what can be connected?

Answer: Remove the igniter tube and clean it. You may need to change the rubber gasket.

Question: The gas water heater VPG-18 Astra does not ignite, since there is no pressure in the hot water tap, while the pressure in the cold water tap is excellent. What could be the reason?

Answer: There may be different reasons: the heat exchanger is clogged with scale, the column filter is clogged, a blockage in the hot water pipe or in the tap itself, etc. You can try this: disconnect the outlet pipeline from the column and look at the water pressure directly at the outlet of the column: if good, it means something is clogged after the column, if it's bad, then there is a problem with the column.

Question: Astra water heater installed. When the water is turned on, the main burner does not light up or lights up, but it burns very weakly and the flame is not regulated. There is a suspicion that it is time to change the membrane, but maybe the problem is something else?

Answer: Yes, most likely a membrane. It is not shaped, you can cut it yourself from sheet rubber up to 1 mm.

Question: Help me find the cause, Astra 8910 02 gas water heater, when hot water is turned on, the column goes out from time to time, I cleaned the thermocouple to a shine, the membrane is in good condition, but just in case I replaced it with a new one, the water pressure is less than that of a cold one, for which still pay attention?

Answer: Maybe the draft is bad, or the draft sensor is acting up. If there is no draft sensor, then there is a tube curved in a hook at the top of the water heater and going to the igniter. The air necessary for combustion is supplied through this tube to the igniter. If the draft is broken (and, accordingly, the removal of smoke), then not air, but smoke will go through the tube, and the igniter will go out, the thermocouple will cool down and the column will turn off.

So even without a draft sensor (it responds to an increase in temperature in the upper part of the column), but with such a system, the column reacts to deterioration / lack of draft. The igniter flame must hit the thermocouple. If for some reason this does not happen, then due to insufficient heating of the thermocouple, it gives less current and the solenoid valve shuts off the gas supply to the burner.

Question: Geyser Astra, model 8910, 1.5 years. From the very beginning of the connection, when gas is added to the hot water temperature rises (from warm to noticeably hot), when the gas supply control knob is turned to the left, when it is set against the right small red flame icon on the front cover of the column, the column starts to "sing" and crackle. The pressure of water, cold and hot at the outlet, is satisfactory, but the temperature of the water (for example, when filling into the bath) is low. I'm afraid to increase the gas supply. With a meager turn of the knob to the left, it continues to "sing" and crackle even more strongly. I don't think this is safe. Is it possible to somehow solve this issue?

Answer: if it’s like a kettle before boiling, then this is scale. Needs to be cleaned and washed.

Question: Who removed the heat exchanger from the gas column Astra HSV-18? Share your experience, I just can’t unscrew it, I’m already pulling with a gas wrench with all my might, but it doesn’t give in.

Answer: The inlet and outlet of the heat exchanger are screwed with union nuts with fittings. It is unscrewed with ordinary keys, but there should be two of them: the fitting is held with one key, and the nut is unscrewed with the second key (you can vice versa: hold the nut and unscrew the fitting). When using a gas wrench with force, the nut may crack. There are difficult cases when water seeps into this connection and over time the connection turns sour. Then it is better to remove the column, put it on the floor or on the table and unscrew it.

Question: Tell me, the gas water heater Astra HSV-18 stopped lighting up. I disassembled the frog, changed the stem with the mushroom and the membrane. After that, the column lights up only at maximum pressure and, accordingly, almost does not heat up. What can be done? there is an old frog without a disk.

Answer: If the membrane is black, so be it. If there is a 22-key plug on the front of the water block, unscrew it. A filter is installed there - remove it. The adjusting needle of the pressure regulator is screwed into the plug, try to unscrew it. It will break and then it will not be a pity to buy a new regulator with a disk, you can adjust the pressure without disassembly. With the plug turned out, clean the hole in the block with a D2 mm needle.

Question: A year and a half ago, we purchased and installed an Astra water heater (geyser). They called gas workers who looked at the water pressure and advised us to buy this model. After some time, the pressure of hot water in the bathroom decreased (private house, kitchen and bathroom nearby). The kitchen has remained the same. In the kitchen, the column turned on immediately, and in the bathroom only if water flowed in the kitchen. Today my pipes froze, for some time there was no water. Now the water pressure is the same as it was. But the column does not turn on. Even if I turn on hot water, both in the bathroom and in the kitchen. Prompt with what it can be connected?

Answer: There is one hot water outlet from the column. If the pressure of hot water in the kitchen was good, but in the bathroom it was bad, then the problem was not in the column, but in the pipe or faucet in the bathroom. Try adjusting the water flow with the appropriate adjusting screw. This is such a round piece in front of the water part (frog).

Question: The gas water heater Astra HSV-18 does not ignite at all, it goes out. We think that the membrane has burst, or there is no pressure (it's just that earlier the pressure from the tap in the kitchen was greater, now it is weaker, much, but it still seems enough to turn on the column). Let's see if it's clogged. The fact is that the pressure of water from a cold and hot tap is very different (hot goes much weaker). The igniter seems to be good, it does not bother, it is almost inaudible, it burns constantly. What can be done?

Answer: Try to disconnect the water outlet from the column and light it. If it lights up, then your pipes are clogged, if not, then either the membrane is torn or the filter screen is clogged. Unscrew the regulator wheel on the front of the water block, there is a nut for 8. Under it is a nut for 22. Unscrew it and pull out the filter mesh. I've had the same column for 5 years now. The igniter was noisy. I took a spring from an automatic ballpoint pen and inserted it into the igniter outlet. There's a notch that just fits. It is located under the guide petal of the flame. You don't need to parse anything. Got a splitter. Now the igniter is not audible at all.

Question: An Astra 8910 gas water heater was installed in the house. Once again, having dismantled the heat exchanger and poured an antiscale solution into it, I decided to check where I have strong pressure losses. What we have: water pressure 1.6 atm (3rd floor + water tower), 12.5 liters per minute from a cold tap. As if it is clear that the column reduces the pressure of water. After descaling, the water flow improves. So, the pressure of cold water is good - 12.5 liters per minute.

I connect the flexible inlet and outlet connections of their column with a nipple - the pressure is almost the same. Installed a flush heat exchanger. The pressure has decreased quite a bit. Thus, I found that the lion's share of the head loss occurs in the water block. 3.5 liters per minute comes out of the hot tap! Cold 12.5, and hot 3.5! There is a GOR-HOL regulator on the water block. It stands in the HOL position, providing maximum water passage through the column. Maybe this regulator inside is broken in the HOR position, and the column slows down the flow as much as possible because of this. How to check it?

Answer: There is nothing to break. Most likely the filter standing there (mesh in the form of a tube) is clogged. It is necessary to unscrew the nut, which is under the gore-hole adjusting handwheel, and look. I remember a similar case. And the heat exchanger was washed, and the water part was dismantled, and they didn’t do anything, but there was still not enough water at the outlet. It turned out that on the cold water pipe at the connection in front of the column, those who installed it pinched the gasket, and initially little water entered the column.

Question: I have an Astra VPG-21 water heater. 5 years worked well, but there was a malfunction. Symptoms: The wick goes out during ignition, when you release the handle. I press the left handle - gas is supplied to the wick. I turn it counterclockwise - the piezo works, the wick lights up, I stand waiting for the thermocouple to warm up. After any number of minutes of waiting, I release the handle - the wick goes out, but should continue to burn.

The last week, it often turned out that the column was turned off, for what reason the wick goes out, I did not have time to finally calculate it. Often had to go to light it. And here it turned out that sometimes it is quite difficult to kindle it, that is, it was necessary to heat the thermocouple for almost 2 minutes. And then she didn't want to fire at all. A few hours later, it ignited the first time in 30 seconds. But then it went out again and did not light up for a day. Then it lit up one last time and I have not been able to do it again until now. Can you tell me how to troubleshoot and troubleshoot?

Answer: It is necessary to check whether the tip of the thermocouple is smoky, if necessary, carefully clean it with fine sandpaper; whether the thermocouple is well washed by the igniter flame, if necessary, clean the nozzle (it is often called a jet) of the igniter with a very thin wire; a thin tube goes from the thermocouple to the electromagnetic valve (EMC), where it enters the EMC, unscrew the nut, pull out this tube and
clean the contact with a zero-pointer (or a matchbox scratcher), insert the tube into the solenoid valve and tighten the nut without excessive force. Is there a draft / overheating sensor in the column?

If there is, then clean the contacts on it. If all this does not help, then, most likely, it is necessary to change the thermocouple. Problems when turning on / off the column are possible due to the fact that it is time to replace the membrane in the water part (the water part is also called the frog). The draft sensor with a solenoid valve make up a series circuit in which a heated thermocouple gives current, if there is a bad contact, the water heater will not turn on. The thrust sensor is triggered by overheating - the contact opens in it from the heat, the current disappears in the circuit, and in the EMC the electromagnet "releases" the valve, which shuts off the gas. It is easy to check the serviceability / malfunction of the thrust sensor: it is enough to short it, if after that the column works, then it is faulty.

Question: The gas water heater Astra 8910-02 always lights up the igniter for a very long time, you have to press the button for about 30 seconds so that the igniter lights up and it has always been like this, since the installation of the column. And the second question, recently, already during the supply of hot water, both the burner and the igniter constantly began to go out, after this attenuation, it is even more difficult to light the igniter, you need to press the button much longer to ignite. The column is about 5 years old.

Answer: It might help. In columns of this type (that is Neva, that Astra) - the principle of operation is absolutely the same.

Question: Geyser Astra HSV 21-2. It crackles strongly when water is supplied, and it does not matter if it burns or not, what is the reason?

Answer: You probably have a recirculation pump installed in your plumbing system (in the entire system). If this is the case, then it is better to connect the home system to the general water supply with a soft or plastic connection.

Question: Tell me: they lit the Astra 8910 gas column, turned on the hot water, the column itself either goes out or lights up. I was told that it is either a membrane or the stem does not go well. He opened the block, lubricated the rod with graphite grease, changed the membrane upside down. Worked for several days. Then the same thing. I bought a new block with a bronze top mount with a spring, the old one didn’t have this, the store said that it should be so. The stem doesn't move at all. Well put and now even the wick does not light up. What can be done?

Answer: In the old block, replace the membrane (it has stretched) and everything will be fine. The wick does not light up because you have done something a little. It should light up, at least when the button is pressed. The mount with a spring is used to replace / stuff the stuffing box seal of the stem, before there was a rubber ring inside, but it was very inconvenient and, most importantly, it was not always possible to change it. There, the thrust ring on the cone did not hold well during removal and installation. Try to pull the rod out on a new dropsy with your hands, and then drive it back. Should walk with little resistance, but freely and without binding. Also try turning the venturi all the way on the front of the dropsy.
