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

Open the gas cock and water valves. Connect the machine to the mains.

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

To turn on the device, you just need to press the power button and open the hot water tap. To control the temperature, you must press the "+" or "-" button and select the temperature you need. Until the temperature you have selected is reached, the reading on the monitor will flash.

If it does not reach this value within thirty seconds, the water faucet icon is displayed on the monitor, which indicates the need to increase or decrease the 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 encounter malfunctions (the flame goes out, does not ignite), then where the causes and methods for their elimination are described.

Gas-consuming equipment is potentially dangerous

To avoid emergency situations, it is important to learn how to use gas water heating equipment. To properly turn on the gas column, you need to follow certain rules developed by the manufacturer and described in detail in the instruction manual

Instructions on how to turn on the geyser video

Today, many people use gas water heaters. They provide hot water even when it is turned off. But many consumers have a prejudice that gas water heaters are a great danger. Modern geysers debunk this myth. If you set fire to the column correctly, it will work properly and is completely safe. Geysers Vaillant, Junkers, Bosch, Ariston enjoy good reviews.

If you have taken care of the arrangement of your country house in advance and installed a gas water heater, you have the last step on the way to a warm and comfortable life. And this step is setting up and properly turning on the column. To make the gas water heater work, you have to do a few simple steps. First make sure that the gas supply valve that supplies gas to the column is open. Then open the valve responsible for supplying water to the tank of the water heater. Turning on or ignition can be carried out in only three ways, which depend on the design features of the column.

Modern gas boilers are absolutely safe, unlike their early predecessors. Most of the key processes associated with their correct operation are simplified and do not require additional training from the user. But despite this, do not forget that any gas appliance is a source of potential danger.

Consider the example of Bosch WR10.B, WR13.B, WR15.B gas instantaneous water heater models made in Germany, for the markets of Russia, Ukraine, Belarus. These models differ in the amount of heated water.

Before starting, check if the gas and water valves are open, if two 1.5 V R batteries are inserted. These models of heaters are equipped with electric ignition, as evidenced by the index B at the end of the name. Electric ignition takes place using batteries.

To turn on the device, you need to press the power button on the front panel of the device, the column is prepared for operation, is in standby mode. In order for the heated water to go, you just need to open the tap. At this point, the pilot flame is ignited and after four seconds the main flame is ignited, so that the pilot flame is extinguished after approximately twenty seconds.

These devices do not have a constantly burning wick, which is economical as there is no constant gas flow. During a long break in operation, air can accumulate in the gas system, which will prevent the correct operation of the igniter 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. Water heating is regulated 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.

On the video, in addition to the startup procedure, you can also learn about setting up the column:

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

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 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 off, move the slider to the left until it stops. After a couple of seconds, the pilot flame will go out. Close the gas valve and water valves.

An easy way to ignite how to turn on a Bosch gas water heater

The use of modern gas water heaters usually does not cause difficulties

When buying speakers, you should pay attention to the presence of a passport and a guarantee for the goods.

It is also very important that, along with the column, the seller issues instructions for its operation.

How to fire up a Bosch speaker:

Move the knob to the right if it is in the off position.
The regulator should move to the "Piezo ignition" position. This means that the spark icon and the vertical buttons will connect.
The start button should be “drowned” with your finger, while pressing the piezo power button

The characteristic clicks will notify that the piezoelectric element has worked.
It is important to ensure that the flame does not go out for the first ten seconds. Then you can translate the power to the desired level.

After the power is transferred to the desired one, the flame constantly burns in the mode that was set. But when hot water is turned on, the column starts automatic heating of water. Turning off the column is simple - you need to move the slider all the way.

Why does the column turn on by itself

If spontaneous switching on of the geyser without water is observed, the problem may be that somewhere in the hot water pipeline, possibly passing through the wall, a leak has occurred. After 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 the tap is turned off, it continues to work. The reason lies in the diaphragm, hardened from hard water, located inside the water regulator.After turning off the hot water, the membrane is in no hurry to return to its place, continuing to press on the stem that opens the gas supply. You can fix the problem by replacing the diaphragm.

The device and principle of operation of Bosch speakers

• Semi-automatic columns - the device has two burners: the main and the ignition. The wick burns continuously. When the DHW tap is opened, the igniter ignites the gas on the main burner. The ignition of the igniter is carried out using a piezoelectric element.
• Automatic columns - turn on independently when the DHW tap is opened. The ignition unit produces a spark on the burner, igniting the gas. Bosch automatic gas water heaters, in turn, are divided into two subgroups:
• battery powered;
• using a hydrogenerator to produce sparks.

In addition to the separation according to the principle of ignition, Bosch speakers are divided into two classes according to the internal structure. There are water heaters with closed (turbo) and open (atmospheric) combustion chamber. Turbocharged have built-in fans that blow air to 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 connection and use rules established by the manufacturer.

More information about the technical characteristics of water heaters can be found in the table:

Technical characteristics of geysers Bosch

The Bosch concern can be called one of the recognized leaders in the production of high-quality water heating equipment. The excellent reliability of this product is confirmed by its demand and only positive feedback from professionals and buyers from all over the world. A distinctive feature of products from Bosch has become a set of simplified functions.

Open type how to start a geyser

Flowing geysers installed in residential premises cause a lot of controversy. It should be noted that modern gas water heaters are not dangerous if you follow all the rules for their use. The rules for handling the column should be known to everyone who lives in an apartment or house and uses such a column to heat water.

If there is a large accumulation of gas in the room, it is necessary to open the windows to reduce the concentration of gas

It is important to know that in the presence of gas in the room it is strictly forbidden to turn on electrical appliances and fire. If the column is malfunctioning, you should call the gas service

How to kindle an open type column:

It is strictly forbidden to kindle a column if there is no reverse draft in the chimney.
Do not turn on the device without understanding the instructions.
It is important that the room is equipped with a constant supply of air.
You can not independently repair or make changes to the operation of the gas column.

When kindling, do not touch the front of the panel. When you turn on the column, it is better to set it to low power. It should be noted that modern models of columns are equipped with safety devices that stop the operation of the column if there is no traction.

Device and principle of operation

Bosch produces several types of gas water heaters.

• 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 with a simple push of a button. The column will heat water only after the owner of the house opens the tap, from which hot water will have to flow.
• A column that can work with a hydrogenerator. This unit works in the same way as on batteries, only a spark is obtained using the operation of a hydrogenerator.

Gas devices have a rather complex device. Before you start looking for the right model of this type of equipment, it is first better to find out the features of its design.

It is worth highlighting several main working components of products.

• Frame. It is made by stamping from durable sheet steel. The case has an enamel layer of protection, which helps the unit withstand high temperatures for a long time, and also gives resistance to various damages. Behind the wall of the case, heating elements and casing parts are fixed, which closes the "insides" of the column. And also on the body are the boiler controls.
• Observation window. It looks like an ordinary hole, which is located on the front side of the product and is made in order to visually control the fire of the burner.
• Control system. This unit has two separate regulators - for pressure and for fluid temperature. The boilers are manufactured with regulation of the water pressure, which is produced by turning the handle - you can increase the readings by turning clockwise, and decrease it - against it. The level of flame burning can be set using the slide control.

• Entry and exit highways. The supply of both water and fuel will be carried out using threaded fittings.
• Chimney. The outlet of the gas that has already worked out 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.
• Node for traction control. This element looks like a sensor. It will monitor the level of available traction. In case of its decrease, the machine will immediately turn off the unit.
• Gas node. This includes a burner and igniter, a special combustion chamber, a special gearbox and all the necessary elements for ignition.
• Water node. Here there is a heat exchanger, released from the pipe in the form of a coil, and strong pipes for transferring and exiting liquid.

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

The principle of operation of the gas device is as follows:

• 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 large quantities during the combustion of fuel;
• rapid heating occurs by means of heat transfer at high speed due to the high level of thermal conductivity of the materials used;
• exhausted gases will be released under the influence of chimney draft.

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

That is why flow products are divided into 2 classes.

• Ignition machine. The ignition of the fuel in the burner occurs at the same time as the valves with hot liquid are opened.
• Ignition semiautomatic. The ignition of the fuel in the combustion chamber comes from the igniter, which must first be ignited.

In the markings of the Bosch brand units there are indices of letters, which indicate a type of ignition system, namely:

• "P" - piezo ignition;
• "B" - electric ignition;
• "H" or "G" - ignition from the hydro generator.

Advantages and disadvantages

Gas devices from the Bosch concern have the following advantages:

• long service life - devices of this manufacturer work smoothly for many years;
• excellent simplified functionality that pleases consumers;
• a huge range of models - among the range you can find both simple and advanced models; a considerable number of options and subspecies of Bosch devices allows you to choose the most suitable model for home use, installation in an office or installation in a production room;
• excellent security system, in addition, competent control of the removal of fuel combustion products;
• temperature control, as well as an automatic system for the operation of the entire device.

Bosch units have such disadvantages as:

• a small number of domestic service workshops;
• high cost of production;
• high prices for spare parts.

Installation and connection

The choice of this kind of device should be taken very seriously, since the placement of such a device in a dwelling in the kitchen of which there is no chimney channel (it should not be confused with a ventilation channel) is impossible according to the norms. The best way out of this situation is to buy a product with a closed combustion chamber. In such a device, a coaxial pipe is used as a chimney, which will be led through the wall directly to the street. The circuit designer should warn of 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 placing 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 such a device in it is not allowed. To connect the outlet needed to remove the remains of 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 at the exit from the product should have parameters of approximately 30–50 cm.

The installation of the device is carried out at such a height that children cannot reach it, but adults should easily reach all available regulators. 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 to remove the products of combustion of fuel, 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 get into the home to the neighbors, which is not very good.

A good way out is to install the purchased device on the wall according to the existing special project and connect only the water supply hose to the unit's nozzle. Only an experienced specialist may connect the product to a gas hose and carry out other work with combustible fuel.

The procedure for installing the device is not original. Where the apparatus is fixed on the wall, it is necessary to make markings for future fasteners. The entire height of the fixtures is calculated in such a way that the chimney that exits the appliance vertically has parameters of at least 30 cm. The pipe to the chimney is installed at a predetermined angle. Its parameters can be calculated by applying the installation scheme.

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

• measure how many centimeters between the fasteners on the product, transfer these parameters to the wall using a level and a ruler;
• make small holes in the wall for dowels or hooks;
• after mounting the hooks, you need to hang the device on them;
• further, the installation of water hoses is carried out, they are screwed to the inlet pipe of the water heater and to the drain;
• to check the tightness of the connection, you need to open the taps with cold and hot water;
• the chimney pipe is fixed on the placed unit using the scheme; the use of corrugations is allowed;
• to connect the gas pipe, you will have to invite a professional who will do it as accurately as possible and give you the documents on the registration of the device; at this stage, the connection of the water heater can be considered complete, the boiler can be put into operation.
