How to set up a gas water heater: adjust gas, water temperature

The need to install a column may arise for many reasons. However, every owner of the device faces a typical problem: incorrect settings of the gas water heater at the connection stage leads to incorrect operation. As a result, the expected results are not met, and further use of the device leads to malfunctions. Appliance manufacturers try to get around this problem by providing an automatic adjustment system. The obvious solution had no effect: not every buyer is willing to overpay for complex equipment with an unclear operating principle. Many people prefer to spend some time learning how to set up a gas water heater themselves.

Preparing to set up a water heater

Although there are instructions for the Bosch, Selena and Neva gas water heaters on how to set them up correctly, not everyone understands how to do this. Having made a mistake at the very beginning, the device begins to work not as it should. You should start by regulating the water supply.

First of all, adjust the water regulation. If you do it at the last moment, then all the settings will be incorrect. The flow must be the smallest . The values ​​can be found in the documentation, they are usually 6, 10 and 12 liters.

The main thing is that there is only one tap for work.

Starting the device and adjusting the temperature

To correctly set up hot water in the device, you must:

• Open the hot water mixer fully;
• Using the water switch, select the required temperature value;
• Close the tap.

According to the advice of professionals:

• Wait for the moment when the pressure in the line drops, but the column will still work;
• Turn the water toggle handle to the maximum;
• Turn the gas regulator to the minimum value until the temperature is as desired.

For final preparation, it is worth adjusting the gas supply. To do this, you need to look at the technical data sheet and find out the minimum value for this brand. The toggle switch is turned to the minimum value.

Turn on the gas supply valve. At the gas water heater, Electrolux and Ariston do this after connecting to the network. The Oasis, Junkers and Bosch gas water heaters are connected when the batteries are installed.

The hot valve is turned on and the device starts working.

How to adjust the water temperature

Turn on the mixer and check the water heating temperature. It must be twenty-five degrees more than the original one. It is worth noting that the water in a gas boiler heats up gradually. The geyser is adjusted using the gas lever.

Reference! You can also adjust the temperature using the water toggle switch. If the flow force increases, the heating temperature will decrease.

Professionals do not recommend heating water above fifty-five degrees. This has a bad effect on the device, as scale forms.

Blood pressure problems

Setting up a geyser requires some time. Accordingly, the result will be visible later. After each stage, it is worth pouring out the water and letting it heat up again so that the values ​​are correct. Low pressure in the device may interfere with normal operation.

If you have problems with blood pressure, you should perform the following manipulations:

• Remove the casing from the device;
• Loosen the locking bolt, use a pressure gauge to check;
• Remove the seal from the adjusting screw;
• Turn on the boiler;
• Set the values ​​to maximum, unscrew the hot water supply taps;
• Adjust the desired pressure.

The Bosch gas water heater, namely its pressure in the nozzles, is regulated in the following way:

• Remove the casing;
• Attach a pressure gauge;
• Loosen the locking screw;
• Attach a pressure gauge to check the pressure in the injectors to the nozzle.

Next, the Bosch gas water heater with maximum thermal power is regulated:

• Remove the seal from the screw;
• Turn on the device;
• Hot water taps are turned on;
• The adjusting screw adjusts the pressure in the nozzles;
• Put the seal in place.

There are brands that have a special “Winter-Summer” mode with temperature adjustment. This handle was made at the bottom of the Ariston gas water heater. Adjustment of the Oasis gas water heater is located on the front panel. The peculiarity of the mode is that in winter the power is higher than in summer. The heating power of the liquid in the column is directly related to the temperature of the inlet stream. In winter, the regulator is set to “maximum”, the heating will be at its highest. In summer, the temperature of the inlet flow is higher and is set to the minimum position. This saves resources. It is easy to remove bad pressure when checking.

To do this, you must perform the following manipulations if the device has already been used:

1. Pay attention to the rubber membrane. The performance of this part is directly related to the pressure in the line. At the moment the integrity of the membrane is broken, namely when it is exhausted, gas does not flow and the burner does not turn on. The problem is solved by replacing the part.
2. Pay attention to the mesh filter. It is located at the entrance to the water block. The water pressure becomes lower due to debris clogging the part. The problem is solved by cleaning.

Popular models for apartments and country houses

A review of efficient Oasis instantaneous water heaters with an affordable price will help you make the best choice for arranging comfortable living in city apartments and the private sector.

Model “Glass 20VG”

Glass 20VG has a low cost, energy-saving function, an anti-freeze system and sufficient performance to supply hot water to two points. Disadvantage: battery operation and the need for a chimney.

The TUR 24 consumes a little more power, but has forced ventilation, an electrical connection and greater performance, which makes this model more affordable. Installation and connection methods

Installing a gas water heater for the first time or when replacing a faulty one that has failed requires various preparatory operations.

When installing a gas device, the project must be agreed upon and the gas wiring to the installation site of the column must be correctly completed. The document indicates the characteristics of the room, installation location, and type of device. It is better to entrust these works only to specialized organizations licensed for this type of activity. The connection is made in accordance with the instructions and SNiP.

Before connecting, turn off the gas. Using a gas wrench, unscrew the hose nut. It is difficult to damage a flexible connection using a hose, but if the connection was made using metal pipes, it will have to be dismantled by sawing. It is better to replace old hoses.

Then turn off the cold water supply. Begin installing the water heater according to the attached diagram. The distance from the outlet of the exhaust gas column to the chimney must be at least 50 cm, but in rooms with a height of 2.70 m, installation with a height of 25 cm is allowed.

At the next stage, connect the water supply, connecting to the input and output of the column. Modern flexible hoses allow you to avoid leaks by tightening the fixing nuts. When using pipes, it is necessary to eliminate leaks with tow or FUM (tape sealant).

Then connect the gas. It is better to use the services of a specialist.

How to adjust the flame of a gas water heater

Another way to set up a gas water heater is to adjust the flame. On the body of semi-automatic and automatic machines there is a handle designed to adjust the gas. With its help, the supply of blue fuel increases and decreases. The power of the device is directly related to this part.

As soon as the flame becomes larger, the gas consumption will be higher and the water will heat up better. Professionals advise changing the gas transmission speed to properly set the burner. As soon as the burning intensity is selected, the knob for changing the water pressure is applied. In order to change the combustion temperature, it is worth changing the “Winter-Summer” mode.

Adjusting the igniter of the gas water heater will help reduce gas costs in semi-automatic machines. The wick is adjusted using the bolt on the pilot burner. You should be careful when making settings. If you reduce the flame of the gas water heater's igniter too much, the device will stop working. If the flame increases excessively, excess gas consumption will occur.

Setting details

These devices have only one geyser temperature regulator. Thanks to it, the heating temperature and power are adjusted. The self-diagnosis system evaluates the operation of the components when turned on. If there are problems, the red light comes on and the device is blocked from starting. Then it is necessary to adjust the water pressure.

Then you need:

• Remove batteries from the compartment;
• Turn off the microswitch;
• Provide a source of electricity;
• Turn on the hot tap and turn on the microswitch;
• The pressure on the burner should be maximum;
• After saving the settings, the orange lamp will turn on.

In other columns, the water temperature is adjusted by turning the toggle switch and controlling the strength of the water flow.

Important! When adjusting, it is prohibited to exceed the maximum temperature specified in the instructions.

Unfortunately, it is impossible to easily set the settings according to the instructions. Each system has different meanings. If you have difficulties setting up the gas water heater temperature regulator with your own hands, you should turn to professionals.

Poor pressure

Let's look at what affects the water pressure in a gas water heater:

1. Presence of blockages. Every pipe through which water moves tends to become clogged with debris. If we take an Electrolux geyser as an example, the blockage occurs in the mesh filter filled with lime and rust. If the water flow is low, the pressure will be minimal.
2. Engineering works. In this case, scale appears inside the heat exchanger. When the water is shut off and the water unit of the gas water heater resumes operation, a “water hammer” occurs, after which some of the scale penetrates into the mixer and forms a blockage.
3. Device power. For Bosch geysers and other models, the power of the device is important. It will create good pressure in the system. If the power of the device is less than eight, then the pressure will be minimal. For good operation of the geyser water unit, it is worth purchasing a device with a power of eight to ten kilowatts.
4. Scale. It usually occurs in metal containers in which water is brought to a boil. In a gas water heater, the heat exchanger is considered a tank. With hard water, scale forms on its walls, which subsequently moves into the tubes, due to which the pressure decreases.
5. Preventive actions. Any device, including a geyser, needs regular maintenance, namely the prevention of blockages. In most cases, a decrease in water pressure occurs due to careless use of the device.

General description of the model range

Italian technologies used in the production of Zanussi gas water heaters are distinguished by their reliability and quality. The body is made of metal, but some models have glass lining. It contains knobs for controlling temperature, power, and a display that displays the set parameters.

Gas water heater from Zanussi

Through the window on the front, the flame on the gas burner is monitored. The Zanussi column is connected to 2 water intake points. But the manufacturer recommends installing on one, it’s more comfortable to use.

All Zanussi water heaters are available with a multi-stage safety system. Working units are equipped with built-in sensors. Zanussi models are activated when the hot water tap is opened. When it closes, the system shuts off the water and gas flow and turns off.

How to solve a problem

If the filter is clogged, you should remove this part from the device. Clean it with a stiff brush and water. If, during cleaning, a violation of the integrity of the filter is noticed, it is worth replacing the part with a similar one.

If the hot water pipe is clogged, you should run cold water in the opposite direction. The plug is removed, a container is placed under the device under water and both taps are turned out. The spout is closed with your finger. It is considered possible that cold water will push the clog forward. It is not recommended to use chemicals that remove scale from the column. Their composition can easily destroy the metal surface. The best option is to use citric acid, which is dissolved in hot water.

If the blockage has advanced further than the pipes, it can easily penetrate into the faucet. The most “vulnerable” places where blockages mainly appear are considered to be a thin rubber hose, a filter and a faucet. The problem can be solved by disassembling the mixer and performing a thorough inspection. Dirt is removed using running water.

Breakage Prevention

To avoid problems with the operation of the geyser, it is necessary to carry out its maintenance at least once a year . It is recommended to call professionals for these procedures, but if you want to save money and perform these steps yourself, you need to disassemble the device, first turning off the gas supply, and thoroughly clean the inside with a brush or rag. To improve the effect, you can use a vacuum cleaner.

Advice! In addition to the water heater, you need to inspect and clean the chimney, since if it is clogged, even a clean water heater will not work. In addition to removing soot and soot, you need to periodically clean the heat exchanger from scale, especially if the pilot light is regularly lit during the day.

So, if a geyser does not heat water well or does not heat it at all, it is necessary to diagnose the device to identify the cause of the malfunction. This problem can cause many breakdowns of this type of water heater, many of which occur due to the lack of regular preventive maintenance of the device. Once a malfunction is detected, you can try to fix it yourself or seek help from specialists if you are not confident in your own abilities.

What malfunctions do the Neva Lux dispenser have?

The display of the Neva Lux geyser indicates an error code when problems occur.

Common fault codes that also occur at the Neva Transit gas water heater:

E7. After seven attempts to turn on the device, it goes out or does not work at all. The problem lies in the failure of the electric valves, the accumulation of soot on the electrode, the mixing of the ionization sensor, or the gas block boiling. The solution is to replace faulty parts or clean the soot with a brush.

L0. Insufficient fuel supply.

Causes:

• Poor water pressure;
• Decrease in temperature;
• Exceeding the pressure of the gas water heater Neva Lux.

The problem can be solved by adjusting the temperature, installing a reduction gear and descaling the radiator.

E0. The device turned off on its own. Fuel does not move into the device. The solution is to check the gas valve of the Neva Lux gas water heater. In most cases, the gas supply stopped for some time.

E8. Malfunction related to the traction sensor. It is usually associated with a clogged chimney or a broken sensor. The solution is to clean the chimney from soot yourself or with the help of utility services, or replace the sensor with a new one, as well as check the tightness of its contacts.

Possible difficulties

When setting up a gas water heater, the following problems often arise:

• changes in water pressure in the water supply;
• water pressure too low.

The first problem can only be solved by replacing the valve or installing a pressure regulator. Otherwise, pressure drops will lead to increased wear of the device and its failure.

In the second option, the water heater will not even turn on. If the water pressure drops suddenly, you should call the city water utility and find out the reason. Perhaps this problem will be quickly resolved. If there is always low water pressure in your locality, you will have to purchase a pump that will help increase it.

Other device problems

In addition to error codes, there are other malfunctions that are also typical for the Neva Transit gas water heater:

1. The appliance is too noisy. In this case, you should start turning the water regulator and reduce the pressure.
2. The gaskets “stick out” in the pipe connection areas. The problem is solved by replacing the element.
3. The display has stopped working. The problem lies in faulty contacts, a broken display and a faulty temperature sensor. The solution is to replace the parts and the display itself.
4. The device stopped lighting up. This problem is also typical for the Zanussi gas water heater. The malfunction lies in membrane stretching, overheating and a broken device element. Solved by replacing the part with a new one.

When repairing with your own hands, it will take a long time to study the repair material and actually set up the gas water heater. The result the first time may not be the same as in the repair instructions in the literature and may even be disastrous. The best option would be to entrust the matter to professionals.
