Bosch geysers automatic and semi-automatic: operating instructions

Let's look at how to light a Bosch geyser using the example of Bosch gas instantaneous water heaters WR10.B, WR13.B, WR15.B, produced in Germany, for the markets of Russia, Ukraine, and Belarus. These models differ in the amount of heated water.

Bosch WR10.B, WR13.B, WR15.B

Before starting, check that the gas and water valves are open and that two 1.5 V type R batteries are inserted. These heater models are equipped with electric ignition, as indicated by the B index at the end of the name. Electric ignition occurs using batteries.

To turn on the device, you need to press the power button on the front panel of the device; the speaker is ready for operation and is in standby mode. In order for heated water to flow, you just need to open the tap. At this point the pilot flame ignites and four seconds later the main flame ignites, so the pilot flame goes out after approximately twenty seconds.

These devices do not have a constantly burning wick, which is economical since there is no constant gas consumption. If there is a long break in operation, air may accumulate in the gas system, which will prevent the igniter from working properly and, as a result, the main burner will not be able to ignite.

To fix this problem, you need to open and close the hot water tap several times. Adjustment of water heating occurs by reducing its flow; by turning the valve clockwise, it decreases; counterclockwise, respectively, vice versa, the flow increases and the temperature decreases. At a low water temperature, gas costs are reduced and less scale is formed in the heat exchanger.

Installation and connection

The choice of this type of device must be taken extremely seriously, since placing such a device in a home in the kitchen of which there is no chimney duct (this should not be confused with a ventilation duct) is prohibited according to the standards.
The best way out of this situation is to purchase a product with a closed combustion chamber. A similar device like a chimney uses a coaxial pipe that will be led through the wall directly to the street. The specialist designing the circuit should warn about such a solution to the problem. The installation location of the product is usually determined by an existing and approved project, so those who want to have a high-quality water heater in their kitchen should be clearly familiar with the rules for locating the unit in a residential building. Such products can only be placed in the kitchen or in any other non-residential space, with the exception of the bathroom, since according to updated standards, the presence of this type of device is not allowed in it. To connect the outlet needed to remove the remaining burnt fuel from the device and to enter the chimney, which is located in the wall, you can choose a steel pipe with a wall thickness of 1 mm. Its diameter is from 1.2 cm. The use of a pipe made of aluminum sheet or corrugated type is not recommended. The section of such a pipe when exiting the product should have parameters of approximately 30–50 cm.

The device is installed at such a height that children cannot reach it, but adults should be able to easily reach all available controls. The distance from the wall closest to the device is at least 0.15 m. There should also be no obstacles in front of the product itself at a distance of 0.6 m. The pipe, which is intended for the removal of fuel combustion products, should only go to the chimney, if it is a separate building, or to a special chimney channel, which is usually built into the walls. Connecting the product to ventilation is strictly prohibited, since combustion products can enter the neighbors’ home, which is not very good.

A good solution is to mount the purchased device on the wall according to an existing special design and connect only the water supply hose to the unit’s branch pipe. Only an experienced specialist should connect the product to a gas hose and carry out other work with flammable fuel.

The procedure for installing the device is not original. Where the device is mounted on the wall, you need to make markings for future fasteners. The entire height of the fastenings is calculated so that the chimney pipe that exits the device vertically has parameters of at least 30 cm. The pipe to the chimney is installed at a predetermined angle. Its parameters can be calculated using the installation diagram.

After determining the hanging height of the device, you need to take the following steps:

measure how many centimeters are between the fasteners on the product, transfer these parameters to the wall using a level and ruler;
make small holes in the wall for dowels or hooks;
after installing the hooks, you need to hang the device on them;
Next, water hoses are installed, they are screwed to the water heater inlet pipe and to the drain pipe;
to check the tightness of the connection, you need to open the taps with cold and hot water;
the chimney pipe is secured to the placed unit using a diagram; the use of corrugation is permitted;
to connect the gas pipe, you will have to invite a professional who will do it as correctly as possible and give you documents on the registration of the device; at this stage, the connection of the water heating device can be considered complete, the boiler can be started for operation.

Design and principle of operation

The Bosch company produces several types of geysers.

Battery powered design. The burner will need to be turned on using electric ignition, and a special electrode will supply the spark.
Bosch device with piezo ignition. You need to light the igniter by simply pressing a button. The heater will begin to heat water only after the owner of the house opens the tap, from which hot water should flow.
Column that can work with a hydrogen generator. This unit works in the same way as with batteries, only the spark is obtained using a hydrogenerator.

Gas devices have a rather complex structure. Before you start searching for the desired model of this type of equipment, it is first better to know the features of its design.

It is worth highlighting several main working components of the products.

Frame. It is produced using stamping from durable sheet steel. The case has an enamel layer of protection, which helps the unit withstand elevated temperatures for a long time, and also provides resistance to various damages. Heating elements and casing parts are fixed behind the housing wall, which covers the “insides” of the column. The boiler control elements are also located on the body.
Viewing window. It looks like a regular hole, which is located on the front side of the product and is made in order to visually control the burner fire.
Control system. This unit has two separate regulators - for pressure and for liquid temperature. Boilers are manufactured with regulation of water pressure, which is produced by turning the knob - you can increase the readings by turning clockwise, and decrease them counterclockwise. The flame level can be set using the slider.

Entrance and exit routes. Both water and fuel will be supplied using fittings with threaded connections.
Chimney. The gas that has already been exhausted goes through the pipe, which is located at the top of the product. The diameter of the pipe will directly depend on the performance of the device and has parameters from 10 to 15 cm.
Traction control unit. This element looks like a sensor. It will monitor the level of available traction. If it drops, the machine will immediately turn off the unit.
Gas unit. This includes a burner and igniter, a special combustion chamber, a special gearbox and all the necessary elements for ignition.
Water node. There is a heat exchanger released from a pipe in the form of a coil, and durable pipes for transferring and exiting liquid.

Products must have means of monitoring the level of fluid pressure in the system. When it drops to critical parameters, the heating element should automatically turn off.

The principle of operation of the gas device follows the following scheme:

as soon as the hot water taps are opened, the necessary coolant enters the heat exchanger;
at the same time, the heating burner is ignited from the igniter;
passing through the coil, the water warms up due to the heat that is released in huge quantities during the combustion of fuel;
rapid heating occurs through heat transfer at high speed due to the high level of thermal conductivity of the materials used;
exhaust gases will escape under the influence of chimney draft.

The Bosch concern offers a choice of water heating products with various subtypes of ignition.

That is why flow-through products are divided into 2 classes.

Ignition the machine. The combustion of fuel in the burner occurs at the same time as the opening of the taps with hot liquid.
Semi-automatic ignition. Ignition of the fuel in the combustion chamber comes from the igniter, which must first be ignited.

The markings of Bosch brand units contain letter indices that indicate the type of ignition system, namely:

“P” – piezo ignition;
“B” – electric ignition;
“H” or “G” – ignition from a hydrogenerator.

Peculiarities

Electrolux water heaters are equipment that can heat water and maintain its temperature for a long time without interruption. The design can perform its functions in any conditions. The technical features of the devices provide the speakers with reliability and safety. The water heating equipment of this company is capable of working not only at one or several water intake points. It has found wide use both in the domestic sphere and in offices.

Each model has its own characteristics and performance, so when choosing a product, the buyer should be guided by personal taste and needs. Let's look at the main characteristics of Electrolux speakers.

Power.
The manufacturing company sells a product that can be of three types and differ from each other in performance and power: low-power equipment - 17-19 kilowatts; medium power - 20-24 kilowatts; powerful - 25-31 kilowatts. Each presented option can work at a certain number of water intake points.
Control method.
The manual control method has long been outdated; it has been replaced by a new, more improved one. Modern models of Electrolux geysers have a built-in burner with independent power modeling. Thanks to this, the equipment is able to control the temperature regime and maintain it at the required level, even with insufficient pressure. The automatic system independently selects and regulates the temperature.
Type of ignition.
The manufacturer sells several models of geysers: with manual, automatic and piezo ignition. Equipment of the first option is now practically not found. Automatic ignition is the most convenient option to use.
Safety.
Electrolux speakers are equipped with three-level and four-level security. When unexpected interruptions occur in the system, for example, pressure changes, a gas or water leak occurs, the device turns off automatically.

Electrolux water heating equipment is characterized not only by improved technical parameters, but also by an attractive design. Everyone will be able to choose the ideal option that will fit perfectly into the interior. Gas water heaters are presented both in a minimalist style and with an improved external panel.

Instructions: how to turn on the gas water heater (video)

Today many people use gas water heaters. They ensure the availability of hot water even when it is turned off. But many consumers have a preconception that geysers pose a great danger. Modern geysers debunk this myth. If you ignite the column correctly, it will work properly and completely safely. Gas water heaters Vaillant, Junkers, Bosch, Ariston have good reviews.

If you took care of the arrangement of your country house in advance and installed a gas water heater, you have the last step left on the path to a warm and cozy life. And this step is setting up and correctly turning on the column. In order for the gas water heater to work, you will have to do a few simple steps. First, make sure that the gas valve that supplies gas to the column is open. Then open the tap responsible for supplying water to the tank of the water heating unit. Switching on or ignition can be done in only three ways, which depend on the design features of the column.

Model range and customer reviews

Therm 2000 Series

This model is considered the most budget-friendly. It can heat 10 liters of liquid in one minute. It has a built-in electric ignition (battery-powered), a burner made of stainless steel, a copper heat exchanger, and an original design. The device is protected from accidents by special sensors for measuring coolant temperature and draft level, and there is also a system that controls the fuel supply.

The Bosch W10 KB model, which belongs to this series, is small in size and low in cost, and therefore is in particular demand among buyers.

Termo 4000 series

Bosch products of this modification are presented in two models - Termo 4000 and Termo 4000 S. They can be with electric ignition and piezo ignition. They can produce 10–15 L in 1 minute. The heat exchanger has a fairly long service life - up to 15 years. The models have a system that guarantees smooth adjustment of the flame and ensures the desired liquid temperature when the pressure level in the water circuit increases or decreases.

A distinctive feature of the Termo 4000 S model is the installed fan, which forcibly removes exhaust gases from the combustion chamber and forces air into this chamber.

In addition, you can buy a coaxial type chimney in order to easily remove combustion products from the house. Opportunities of this kind help to install these products in rooms where there is no ventilation system or a chimney is completely absent. There are three types of products of different power and performance from 10 to 15 liters per minute.

Instantaneous water heaters of this series have the following designations:

Bosch device with automatic ignition (article “B”): WR 10-2B and WR 13-2B, as well as WR 15-2B;
Bosch semi-automatic unit with piezo ignition (symbol “P”): WR 10-2P and WR 13-2P, in addition – WR 15-2P.

Termo 6000 Series

Products in this series are equipped with hydrogenerators to automatically ignite the burner. There is an LCD monitor on the front panel, where the set temperature values are displayed. The heater can be controlled mechanically, and the existing settings are supported in automatic mode. The model is presented in three power options, with performance from 12 liters to 18 liters per minute. However, it is worth remembering that this series of devices is energy dependent. There is a fan here that needs to be connected to the electrical network. The products are marked, which depends on the specific power of the device - WTD 12 AM E23, WTD 15 AM E23 and WTD 18 AM E23.

Thermo 6000 S and 8000 S series

These are mostly industrial-type units from a well-known German brand. The performance of these products will be 24 and 27 liters per minute. These products can supply heated water to 4 to 5 points. Bosch water heaters have electric ignition and an LCD display on the front of the product. The 6000 S series model has 2 fans that remove fuel combustion products necessary to suck in oxygen. The Bosch 8000 S product has a special condensation technology, it is designed for more efficient water heating. In addition, the water valve of this model is supplemented with an electric drive.

Important: all models of gas devices are produced in Portugal, but there is an exception - this is the inexpensive Termo 2000 series, which is assembled in China.

Is it worth extinguishing the wick at night?

Here the choice depends on the type of water heater. In columns with a wick that is regularly on, this is necessary. By turning it off, gas costs are significantly saved.

There is no point in worrying about an accident occurring at night. The device operates safely. The manual for using a gas automatic heater does not say anything about turning off the burner at night. The device has degrees of protection against burner fire.

It is worth turning off the wick in a gas water heater only if there are visible signs of a malfunction, namely: malfunctions, the presence of pops, and also if the burner goes out on its own during operation. If you have such problems, you should turn off the gas and call the emergency gas service.

Operational nuances

Consider frequently asked questions when using geysers.

Why does the geyser itself turn on or off?

Spontaneous activation of the column can occur if there is a hot water supply system flowing to the column. Accordingly, solving the plumbing problem also solves the column problem.

This situation occurs much more often: the column continues to work even when the tap is turned off. This happens because the aperture (loses elasticity) that is installed in the water regulator is incorrect. Once the user turns off the hot water, he will not be able to take the desired position; he presses the gas sensor for a while. In this case, only replacing the worn part will help.

If the membrane loses elasticity, the column may not close

Is it possible to turn on cold water when the water heater is on?

Many users are lazy, do not know how or do not want to set convenient settings for your column, and adjust the water temperature by adding cold to it. You can't do this, here's why:

This is prohibited in the user manual;
When water is mixed, scale forms on the heat exchanger, which ruins it.

Should I turn off my speaker at night?

In older speaker models and those with piezo ignition, the wick is constantly burning. This, on the one hand, is uneconomical, since gas is constantly consumed, and on the other hand, it is potentially dangerous. It's best to turn off those speakers at night and sleep soundly.

A modern gas water heater does not need to be turned off

Modern geysers have an automatic ignition system. A whole set of equipment is responsible for safety:

Traction sensor;
Flame sensor (monitors its presence);
The temperature sensor allows you to keep it up to 90 degrees.

An alarm from any of them will immediately turn off the speaker. This column cannot be disabled. Usually this point is not even written down in the manual.

Common Questions

Why doesn't the gas water heater turn off?

If a gas water heater turns on spontaneously, the cause is often a leak in the hot water pipeline. After fixing it, the problem will disappear. However, this situation occurs extremely rarely; much more often, the user is faced with the fact that the column continues to work even after the tap is closed. This is due to the diaphragm located inside the water regulator or “frog” becoming hardened and losing its elasticity. After turning off the hot water supply, the membrane does not rush to return to its place and continues to press on the rod, which opens the fuel supply. The problem is eliminated if you replace the faulty membrane.

Is it possible to turn on cold water while the gas water heater is running?

Experts categorically do not recommend turning on cold water while the gas water heater is running. There are a number of reasons for this:

The operating instructions prohibit turning on cold and hot water at the same time. You should set the heating temperature, which will allow you to obtain comfortable water without adding cold water.
The main reason is the rapid build-up of scale in the heat exchanger.

The “winter-summer” mode will allow you to quickly change the heating temperature. This function makes using the instantaneous water heater easier.

Do I need to turn off the device at night?

First of all, this issue is relevant for users who have old-style speakers or those with piezo ignition. They have a constantly burning wick, this process increases gas consumption and poses a certain danger. Therefore, it is better to turn off such models at night. This will not only reduce the risk of an emergency, but also save money.

It is not necessary to turn off a device with automatic ignition. The instruction manual doesn't say anything about this. The automatic dispenser has several levels of protection against emergency situations. Therefore, there is no need to worry about any danger.

Any instantaneous water heater has the following sensors to ensure safety:

traction sensor – checks the presence of traction;
ionization sensor – monitors the presence of flame;
thermostat – prevents the temperature from exceeding 90°C.

If one of the sensors is triggered, the device will turn off. The presented sensors provide the necessary minimum safety for the device.

Preparatory work before turning on the Bosch instantaneous water heater

Before turning it on for the first time, you need to remove air from the water heater tubes; this can be done by turning on the hot water tap and waiting for a stable flow of water from the tap; this will be indicated by the absence of any extraneous sounds when the hot water tap is open.

Important! This action can protect the metal parts of the water heater from excessive overheating in places where this is not desirable, namely at the joints of the tubes. You may also have to bleed off excess air in the gas pipes; this is done differently on different water heaters.

This usually happens by pressing the gas supply button or unscrewing the screw from the gas adjustment tube; of course, how to do this on a specific heater is written in the instructions for that same water heater. Also, if the water heater is installed after repair, it is necessary to remove air from the pipes, to do this, open the free valve, or do this using the water heater.

Before turning on, make sure there is draft - this may be the reason why the Bosch gas water heater does not ignite, this is stated in most instructions for instantaneous water heaters, to do this, simply bring a lit match to the window on the control panel and by the behavior of the flame you can understand the presence of air draft: case when the flame deviates towards the window on the control panel, it indicates the presence of sufficient air draft, and this means that the operation of the device will be stable.

For full operation of the device, a large amount of air is needed, since the burner of the water heater consumes a large amount of oxygen, and it takes this oxygen from the room where it is installed, to do this, ensure normal air flow, for this, the door to the room with the instantaneous water heater should not be tightly closed, also in An apartment or house must have a constant supply of fresh air from the atmosphere, otherwise there is a high risk of poisoning by the products of the instantaneous water heater burner.

Important! It is not recommended to use a fan or air conditioner while the instantaneous water heater is operating, as this disrupts the normal removal of gas oxidation products through the collector. It is also not recommended to approach the window while the burner is operating, as there is a risk of burns.

Basic rules of use

Do not use the gas water heater before reading the operating instructions supplied with it. Here is a general list of rules that are relevant for any instantaneous water heaters:

Only specialists from the gas supply company can connect the device to the gas main;
changes cannot be made to the design;
ventilation should be maintained in good condition;
for speakers with an open firebox, the chimney must have good draft force;
During operation, the device should not touch the front panel of the water heater and the smoke exhaust elements.

Note! If you smell gas in the room, you must immediately turn off the water heater and ventilate the room. Gas workers should be called to determine the location of the gas leak.

Do not operate such a device until the malfunction is eliminated.

The following recommendations will help extend the life of your gas water heater:

It is undesirable to set the heating temperature above 55°C to avoid increased scale formation;
it is risky to use a water heater without a water filter if the water in the water supply is hard;
The heat exchanger should be cleaned of scale as it appears.

Compliance with all operating rules will save fuel and increase the service life of the device.

Mandatory Precautions

Instructions for proper operation of the gas water heater are included with any purchased equipment. The principle of operation of most of them is identical to the above, but here the red line should highlight the mandatory compliance with safety rules.

Mandatory preventive cleaning of the gas water heater to avoid compromising its efficiency (you can read how to do this in the document that comes with the gas water heater. Instructions).
It is important to check the condition of the chimneys. This will help avoid clogging.
If the device fails, contact your gas service. Independent attempts to solve the problem are prohibited.

Turning on the device is shown in more detail in the video:

It is enough to understand once how to light the device to ensure comfortable and instant heating of running water. And then you can simply enjoy the operation of this convenient heater.

The knobs are too sensitive, so there are some difficulties when setting the temperature.

Brief introduction to the device

One of the most common myths that scares away potential buyers is that using such equipment is dangerous. However, this superstition is true when using old style models. Today, the devices are advanced and safe, many of them (for example, offers from Bosch) are equipped with automatic protection, in which fuel consumption is blocked in an emergency.

To know the rules of use, you need to make their internal organization. Any company's models include all of the following elements:

Unit with gas equipment;
Water connection block;
Exhaust gas connection system;
Sensors

The case itself looks like a cabinet connected to water and gas. The heating elements are located in its lower part and are represented by the main burner and igniter.

The device works according to the following principle:

Cold water under pressure enters the heat exchanger. It automatically opens the fuel valve;
The ignition device lights up;
The gas will go to the main burner, where it will be ignited by a lighter;
The heat warms the water;
Combustion products are removed through a system of chimneys and hoods.

Therm 4000 S WTD 12/15/18 AM E23/31.

Before starting, you must make sure that, on the plate installed on the device by the manufacturer, the gas marking corresponds to the gas connected to the device. The device has the ability to connect a remote control panel, which completely duplicates the operation of the display on the column.

Open the gas valve and water valves. Connect the device to the power supply.

The water temperature set by the manufacturer is 42 degrees, this is the optimal temperature.

To turn on the device, you just need to press the turn on button and open the hot water tap. To regulate the temperature, you need to press the “+” or “-” button and select the temperature you need. Until your selected temperature is reached, the display will flash.

If it does not reach this value within thirty seconds, a water tap icon is displayed on the monitor, which indicates the need to increase or decrease water flow. If you press the P button, the programmed constant temperature of 42 degrees will appear. Setting the minimum temperature reduces energy consumption and makes it possible to reduce the formation of limescale in the heat exchanger.

But if you know how to turn on the column, but are faced with malfunctions (the flame goes out, does not ignite), then read this article, which describes the reasons and methods for eliminating them.

Suspected breakdowns

If you bought a Bosch gas water heater a long time ago and you know how to light it, but for some reason nothing happens, then in this case you need to look for a solution to the problem in acceptable breakdowns. What could it be?

If the wick in a dispenser running on Bosch gas does not light or it goes out when the tap on the mixer is opened, then in this case you need to examine the gas pressure reducer, provided that it does not stop working on liquefied gas.

When the outlet water is not cool or hot enough, in this case the problem can be eliminated by correctly setting the temperature regulator on the column.

If your Bosch gas water heater does not turn on, you should first check the condition of the batteries and, if necessary, replace them with new ones. Also, many people encounter the fact that after a certain period of time, poor water pressure passes through the column. This can be explained by the fact that the heat exchanger, water unit or water tap is dirty. To get rid of the problem, you need to detect the blockage and remove it.

If you are unable to detect a breakdown and remove it on your own, then in this case you need to contact the warranty service, which will carry out warranty repairs.

How to light a bosch Therm 4000 O WR 10/13/15 -2 P gas water heater.

The difference between these models is the amount of water heated per minute. A device equipped with piezo ignition is designated by the letter P at the end of the name. It has the ability to regulate two parameters, water and combustion power. To turn on the column, you need to move the slider to the ignition position and press it down.

Press the piezo ignition button several times until a flame appears on the pilot burner. Wait ten seconds, release the slider and move it to the desired power position. Moving the slider to the right increases the power and to the left decreases it. The column is in standby mode all the time; if you need to get hot water, you just need to open the hot water valve.

When you need to turn it off, move the slider all the way to the left. After a couple of seconds, the pilot flame will go out. Turn off the gas valve and water taps.

Watch the video below for instructions on how to turn it on:

Why does the speaker turn on by itself?

If a gas water heater turns on spontaneously without water, the problem may be that there is a leak somewhere in the hot water pipeline, possibly running in the wall. Once the leak is fixed, the problem will disappear.

Much more often, users are faced not with the fact that the column turns on by itself without water, but with the fact that after turning off the tap it continues to work. The reason lies in the diaphragm located inside the water regulator, hardened by hard water. After turning off the hot water, the membrane is in no hurry to return to its place, continuing to press the rod that opens the gas supply. The problem can be corrected by replacing the diaphragm.

Frame country house: advantages

Such buildings are popular all over the world.
What did they do to deserve the love of consumers? An important advantage is the absolute safety of buildings: the quality of building materials for them undergoes strict control before sale. Another undoubted advantage is the low cost of the project, associated with the comparative cheapness of the materials used. An additional benefit will come from savings on heating the building, which usually costs much more money.

A special technology for constructing a frame country house allows work to be carried out at an accelerated pace.

Even one worker, without heavy equipment and the help of specialists, is able to erect a small one-story building during the warm season, in about 6 months. Experienced builders joke that the only thing easier can be constructing a home out of Lego.

How to choose a unit?

If you need to choose a geyser, then first of all you need to give preference to the one that is most comfortable and meets all safety standards.

In order to make the right choice, you need to pay attention to the following indicators:

productivity;
the water pressure for which the column is designed;
nature of ignition and heat exchanger;
Availability of safety devices and power modulation.

A specialist will tell you all these points when purchasing the speaker. You should also be sure to familiarize yourself with the dimensions of the Bosch gas water heater and how to light it.

Installation standards for Bosch speakers

The existing SP and SNiP stipulate that the connection of Bosch gas instantaneous water heaters is carried out in strict accordance with the rules described by the manufacturer in the operating instructions. When installing, follow the restrictions and recommendations provided by the manufacturer. In addition to the standards associated with choosing a room for a boiler room, the following requirements must be met:

installing a Bosch geyser with your own hands is prohibited; connection is carried out only by a qualified specialist who has the appropriate work permit and license;

the water heater cannot be installed in rooms with high humidity (toilet, bathroom), or hung above the refrigerator;

the distance from the bottom edge of the column to the floor should not be less than 80 cm; if connected correctly, the inspection window will be at eye level;

connection to the gas pipeline, chimney and water supply system is made with pipes, the use of which is permitted by current standards;

The speaker body is mounted on walls made of dense, solid materials that can provide reliable fixation.

After installing the water heating equipment, the Gas Service inspector will check the connection and give permission for operation.

Common causes of unstable operation of Bosch speakers

If your Bosch gas heater does not light up, you can try to solve the problem yourself. You can find out why the speaker is unstable very easily.

Doesn't light up

The reason may be insufficient water pressure; to do this, clean all filters or check the pressure in the main line, in which case install an additional pump.

The pilot flame goes out

It is necessary to check the safety sensors, if necessary, connect them, or replace them.

Goes off when mixing

The mixer filter may be clogged; if so, clean it. Also, the flow of cold water can simply reduce the pressure of hot water; to do this, you need to set the appropriate temperature of the hot water on the column.

Goes off during operation

It may be a matter of insufficient draft, solve the problem with oxygen access to the burner, and also seal the burner manifold.

Possible other reasons

The main reasons why a Bosch dispenser does not ignite is due to incorrect gas pressure settings. To do this, you need to make the necessary adjustments, and then the burner will burn stably.

Features of operation

There are a number of provisions and rules according to which the use of gas equipment is permitted. Let's consider the basic requirements for open-type speakers:

Do not start work in the absence of draft in the chimney or in the presence of reverse draft;
It is not allowed to turn on and ignite without studying the operating instructions;
For normal operation, natural ventilation is necessary (window, vent);
It is prohibited to independently change the design of the equipment.

Dispensers with an open combustion chamber are most at risk of gas leakage. If you smell it, then:

Close the valve;
Open the windows and ventilate the room;
Do not light a fire until the room is completely ventilated;
Contact the repair service.

Before starting the appliance, check the presence of draft in the chimney.

How to properly check

There are two “folk” ways of checking:

Take a piece of paper and hold it near the chimney or ventilation. If the leaf tightens, it means the shaft is working properly. If it falls, you need to clean the hole.
Light a match and bring it to the viewing window. Does the flame deviate to the side? Then you can start the column. If it burns smoothly, check the chimney.

It also happens that everything is in order with the mine, but there is no traction. The room may not be ventilated, so there is no air flow for combustion.

How to turn on the water heater

Before turning on any equipment, there must be water in the heat exchanger. Therefore, you should first open the water valve.

Electric models:

Insert batteries into the battery compartment;
In some cases, you need to turn the power or temperature switch;
Open the gas valve;
Turn on the mixer on the hot position, which will ignite.

Semi-automatic devices:

Start the fuel supply;
Set the power and hold the piezo ignition button until the wick ignites;
When you turn on the water, the burner will light up.

It is not difficult to launch modern technology. What about an old-style product?

Ignition of an obsolete type column

A device with manual ignition is considered obsolete. The design provides for constant burning of the wick and manual shutdown. Ignition occurs from a burning match, less often - using piezo ignition. These include: “Iskra KGI-56”, series L, GVA, VPG. They are equipped with a turn signal or lever to regulate the temperature.

The operating principle is the same as that of modern models. The only difference is in the features of turning on the heating. If this is your first time launching, then you should know that:

There must be a constant flow of air in the room with the column

This is important to keep the flame burning. Therefore, in kitchen doors there is a gap of 5 cm at the bottom

If plastic windows are installed, a ventilation valve is required; It is necessary to regularly check for traction; Check the condition of the gas valve. Open it and coat the joints with soapy water. If bubbles appear, there is a leak.

For ignition, it is more convenient to use long matches that can easily reach the igniter.

Launch of KGI-56

Turn the fuel and water valves. Now turn the left control all the way to the left. Hold down the solenoid valve button if the product has one. Continuing to press the button, ignite the igniter with a match. After that:

Open the hot water faucet;
To light the burner, turn the other knob to the left.

Done, you can go take a shower.

Switching on devices of type L, GVA, VPG

Start as with other types by supplying gas and water. Move the knob on the panel to the first position. Press the valve release button and hold a match to the igniter. Hold the button for another 10 seconds. Just as in the first case, turn on the tap and quickly turn the regulator to the maximum level. After ignition, you can start using it.

You can turn off the equipment by turning the lever until the wick goes out. It is advisable to do this at night and before leaving home.

Use your water heater correctly for long service life and your own safety. Once a year, carry out preventive inspections of the product, clean the parts from scale.

How to use an Electrolux speaker

A permit to operate an Electrolux gas water heater is not required. When preparing documents for connection, it is enough to provide a passport for the speaker or indicate the exact name of the model.

How to turn on an Electrolux speaker

DIY connection is prohibited

According to current regulations, the connection can be made by:

representatives of the company that sold the water heater;
gas service specialists.

There are several basic connection rules:

installation is carried out in accordance with the rules described in SNiP and SP;
the first launch is carried out in the presence of a Gas Service inspector;
be sure to withstand gaps between the stove, refrigerator, and sink;
installation is carried out in strict accordance with the gas supply project;
the room used as a boiler room must meet the minimum requirements: height 2.2 m, area of at least 12 m², presence of a vent or opening window.

How to set up an Electrolux speaker

To change the power, increase or decrease the gas supply, changing the intensity of the flame, focusing on the digital indicators displayed on the screen.

In the Electrolux gas water heater with flame modulation, adjustments are made according to a different principle. The user sets the required water heating temperature. The programmer independently changes the burner power, adapting to the actual pressure in the water supply system.

It is prohibited to regulate the temperature by mixing cold water with hot water.

How to clean an Electrolux speaker

heat exchanger of the Electrolux column - inside the tubes become overgrown with scale, outside the radiator is covered with soot;
burner - the jets become clogged with soot.

During the repair, the technician will remove the column casing, disconnect the heat exchanger and remove the burner. The coil is washed using special chemicals under pressure. The radiator fins are washed with ordinary soapy water. The burner is cleaned with a metal awl. The work is carried out by a qualified specialist who has access and the appropriate license.

Distinctive features of the units

Bosch has a very large range of speakers compared to its competitors. Each model differs in ignition type, performance, design and dimensions. As for colors, the German company produces units in white and gray shades.

Almost all geysers are designed in Germany, with the exception of inexpensive modifications, which are assembled in China. Currently, there are certain series of Bosch . When choosing, it is first of all advisable to rely on the required performance and financial capabilities.

How to light a bosch Therm 4000 O WR 10/13/15 -2 P gas water heater.

When you need to turn it off, move the slider all the way to the left. After a couple of seconds, the pilot flame will go out. Turn off the gas valve and water taps.

Watch the video below for instructions on how to turn it on:

Disadvantages

Despite the huge number of advantages and worldwide recognition, Bosch geysers also have certain disadvantages, which are as follows:

high cost of devices and their spare parts;
in the lack of service centers.

In order to make the right decision and decide whether this or that geyser is needed, you first need to read the reviews about it left by real people and analyze all the advantages and disadvantages.

How to ignite the device

Before starting work, you must open the gas and water taps.

There are three ways to light a gas water heater.

Manually

The manual method was used in older models

. In this case, you have to light it with matches. Here it was necessary to perform a number of such preliminary manipulations:

open the water supply connected to the device;
open the main valve to allow fuel to flow to the igniter;
light the wick with matches;
turn on the valve (main) for gas supply.

Using piezo ignition

We can say that this column is semi-automatic. How to use a gas water heater of this type? All you have to do is press a button

to ignite the wick in the combustion chamber. With the help of mechanical force, the spark is transformed - it is enough to ignite the ignition filter. With this method, a number of mandatory requirements must also be met:

in order to light the main burner, you will need to turn on the main regulator in the fuel supply;
The ignition filter will remain lit when the regulator is returned to the main position and the water is turned off.

Automatically

The ability to automatically turn on is provided by fully improved modifications that are easy and safe to use even for beginners. Hydropower system

are offered by most modern manufacturers (Bosch, its direct competitor Electrolux and many others). The process of starting work is simplified to the limit.

For example, in the Bosch Therm 6000 O, water pressure drives a turbine. It triggers an automatic igniter system inside the device for both the wick and the main burner.
The manufacturer Bosch has the Therm 2000 O and Therm 4000 O lines, which carry out electric ignition from batteries (you will need to monitor their service life).
The Bosch AM1E series speakers already have a digital control panel that will immediately show all possible switching errors.

The fully automated process has one drawback: many homes have low pressure in the water supply, and this may not be enough for the turbine to operate properly. In addition, such devices are significantly more expensive than their less advanced counterparts.

Design and principle of operation of Bosch speakers

Semi-automatic columns - the device contains two burners: main and ignition. The wick burns continuously. When the DHW tap is opened, the igniter ignites the gas on the main burner. The igniter is ignited using a piezoelectric element.
Automatic water heaters - turn on independently when you open the hot water tap. The ignition unit produces a spark to the burner device, igniting the gas. Bosch automatic gas water heaters, in turn, are divided into two subgroups:
battery operated;
using a hydrogen generator to produce sparks.

In addition to being divided according to the principle of ignition, Bosch speakers are divided into two classes according to their internal structure. There are water heaters with a closed (turbo) and open (atmospheric) combustion chamber. Turbocharged ones have built-in fans that force air onto the burner. Atmospheric boilers use natural convection of air masses.

The service life of Bosch speakers is 8-12 years. The service life is affected by the quality of the heated water, compliance with the rules of connection and use established by the manufacturer.
