Algorithm for setting the gas column
Setting up a gas water heater, especially for the first time, is a rather painstaking, but short-lived process. Moreover, next time it will be much easier and faster to repeat the steps.
You need to set up a gas water heater as follows:
- First, it is necessary to bring the water supply to a minimum, which is prescribed in the instructions for each column, for example, 6, 8 or 10 l / min. In this case, one should not forget that you only need to open the hot water tap. After setting the indicators, the tap is closed.
- The second stage is setting the minimum gas position. This will help you to make fine adjustments exactly for the characteristics of this device. At this stage, an electrician is connected. Modern electronic models have a display and are automatically adjusted.
- The column can now be launched. Open the hot tap and measure the outlet water temperature. It should be 25 ° C higher on average than the inlet temperature. If the difference is significantly less or more, you should adjust the gas knob or toggle switch to the state in which the specified result will be obtained.
- The handle (toggle switch) of hot water supply will also help to adjust the temperature. If its flow is increased, the outlet temperature will decrease. If the water pressure is reduced, it will become warmer.
When setting up, it is important to remember that water cannot heat up instantly, so there is no need to rush. After each parameter change, wait and allow the liquid to warm up or cool down.
Note! Experts do not recommend heating water above 55 ° C. This is because scale builds up faster at too high temperatures. Subsequently, it will clog the heat exchanger and the components of the device.
In order to minimize wear on the water heater, it is recommended to close the hot water tap gradually. This will prevent overloading the device's heat exchanger.

How to adjust the gas water heater
The need to install a column can arise for a variety of reasons. However, every owner of the device is faced with a typical problem: incorrect setting of the gas water heater during 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 are trying to work around this problem by providing an auto-tuning system. The obvious solution did not have an effect: not every buyer is ready to overpay for complex equipment with an incomprehensible principle of operation.Many people prefer to spend some time learning how to set up a gas water heater on their own.

Preparation for setting up a water heater
Adjusting the gas column does not take much time, but it requires a careful approach and attention. A painstaking process can cause a lot of questions in an unprepared person. Before adjusting a household appliance, you need to shut off the water flow to a minimum, because it is precisely such indicators that are provided for by the operating instructions. Neglect of these prescriptions leads to the fact that all subsequent settings will not be accepted by the system or will lead to a result that is far from the expected result.
In most cases, the required flow rate is equal to eight, ten or twelve liters, but there are some deviations, both upward and downward. After completing the described procedure, turn off the supply valve and proceed to the next step. As with liquid, it is necessary to set the minimum gas value. These settings are necessary to bring the water heater to the nominal values prescribed for it.
At this step, it is recommended to connect the electronic equipment necessary for the gas water heater. Contrary to expectations, this is one of the simplest operations. It includes: connection of several wires; installation of batteries or consumable batteries used to ignite fuel.
Newer models can be supplied with sophisticated equipment with screens and sensors. Such a system independently performs all the settings and does not require user intervention.
Starting up the appliance and adjusting the temperature
Having prepared the equipment properly, the first start-up can be carried out. The first step is to open the hot water tap and examine its outlet temperature. The values obtained should exceed the input value by twenty-four to twenty-six degrees. If the liquid heats up for too long, or the heating does not reach the required temperature at all, adjust the gas knob by turning it to a satisfactory state.
You can achieve the same results by adjusting the amount of water supplied. The higher the level, the colder the liquid, and vice versa. This is due to an elementary law of physics - the larger the water flow, the slower it heats up. Relying on this method, it is necessary to take into account that the temperature of the stagnant water may differ from the expected one, since the liquid will have time to warm up. Subtleties of customization
When setting up a gas water heater, you need to remember that the liquid cannot reach a comfortable temperature instantly. Don't try to make all the settings for a few minutes - it will take quite a long time. After each stage, you will have to start all over again, namely, drain the waste water, and let it warm up or cool down fresh. In general, such manipulations can take half an hour, and sometimes even longer. It will take an experienced professional much less time.
When setting up equipment from different companies, for example, the Neva gas water heater, you may encounter two difficulties: fluid pressure; weak water pressure, which does not cause a reaction of the device;
Pressure problems
Pressure fluctuations can be triggered by a variety of conditions. Faced with this, there is no need to panic, the situation can be easily solved by replacing a worn valve or purchasing a special pressure regulator. This malfunction can cause serious damage and accelerate equipment wear.
Poor pressure
To eliminate the malfunction, it is enough to replace the leaking membrane. In general, this breakdown does not cause problems, but if the owner needs a lot of hot water, for example, for washing dishes, the column may not cope with heating a large flow.
Self-adjusting the heater may take a long time, and the result may not always be satisfactory. It is best to entrust this procedure to a professional.
Possible difficulties
When setting up a gas water heater, the following problems often arise:
- water pressure drops in the water supply system;
- too low water head.
The first problem is solved only by replacing the valve or installing a pressure regulator. Otherwise, pressure drops will lead to increased wear of the device and its failure.
With 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 fixed. If water pressure is always low in your village, then you will have to purchase a pump that will help increase it.

Signs of a clogged gas water heater
The need for cleaning the Bosch gas flow heater is determined by the decrease in the performance of the device.
Cleaning is required if:
- the water heater simply does not start;
- it turns on, but does not work for long and turns off on its own, while there was no lack of water and gas;
- the column heats up regularly, but the water heats up noticeably worse than it was before;
- the water pressure at the outlet of the heating device is weaker than at the inlet to the heat exchanger;
- frequent triggering of the overheating sensor, although the water heater is operating under medium load.
Clogged pilot jet... It is impossible or difficult to ignite the column if the pilot jet is clogged, due to which the device ignites the fuel with a delay - with a characteristic pop. A faint yellow wick flame, although it should be blue, is a sign of fouling in the pilot.
Chimney soot. If the burner ignites, but dies out almost immediately after ignition, the flue duct of the water heater is dirty. The chimney passability is significantly reduced due to deposits of soot and soot accumulated over the years of using the column. However, the chimney of columns in apartments is more often contaminated with volatile debris.
Preventive cleaning of a gas water heater must be carried out regularly, the recommended frequency is every two years. Otherwise, the column will work worse and worse, aimlessly consuming natural gas and water
Weak air flow. For natural draft, even a small gas water heater requires supply air. And modern dwellings are equipped with airtight window and interior door blocks.
The problem of insufficient draft will be solved by ventilation valves built into window frames, wall inlets, as well as ventilation grilles in interior doors.
Scale in the heat exchanger. Insufficient heating of water in a gas flow heater causes a reduced flow area of the heat exchanger tube, caused by a layer of scale.And the more scale builds up, the lower the water pressure after warming up in the column against the background of normal pressure at the inlet to the heating device.
Soot build-up of the heat exchanger. The greatest amount of soot accumulates in the central part of the finned heat exchanger, transferring heat to running water and contributing to overheating of the side sections of the heat exchanger block.
Uneven heating of the heat exchanger causes a quick response of the overheating sensor. Most often, contamination of the fins with soot develops together with the clogging of the chimney.
Features of setting up different models of water heaters
Gas water heaters with different characteristics and features are on sale.
Some models are equipped with the "Winter-Summer" mode In winter, the temperature regulator is set to the maximum position. In summer, the incoming water is warmer, so the handle is shifted to a minimum.
The automatic dispensers are equipped with a self-diagnosis system. If there is not enough pressure or a malfunction occurs, the device is blocked.
Note! If you were unable to independently adjust the optimal operating mode of the device, call a service center specialist.
Setting up the Neva water heater
The control panel of the domestic gas water heater Neva is very simple. The right knob is used to adjust the water flow, and the left knob is for gas. You can adjust the water temperature with both knobs.
If the left knob is set to “maximum flow”, the device will consume a lot of gas and the water will become hot. The right handle works in a similar way - if you set it to the maximum, the water flow will increase, but it will not have time to get very hot.
Adjust both knobs as needed. Adjust the pressure with the right handle, and adjust the temperature with the left.
Note! The Neva water heater has a peculiarity: if you set the water supply to the maximum, and the gas to the minimum, and vice versa, the device will turn off. To turn it back on, you need to close the hot water tap, and then open it again.
The Neva geyser is quite common and is considered optimal in terms of price and quality.
Correct setting of any water heater will not only significantly save money, but also allow you to use it with comfort. The water heater will last for many years and will not turn off at the most inopportune moment.
disadvantages
It is obvious that any domestic water heating equipment has a number of disadvantages. In this regard, the NEVA 4511 model is also far from ideal. With a rated power of 21 kW, it produces up to 11 liters of hot coolant per minute.
Experts are sure that the equipment "will not cope" with its work if water is taken from two points at the same time. For example, washing the dishes while someone in the household is taking a bath can be difficult. The capacity of the unit is not enough to provide two points of water intake with sufficient hot water. In addition, the design does not provide for a smooth flame modulation system, which cannot be said about more modern speakers.
If you do not need such a powerful unit, and operational know-how is not so important to you, the NEVA 4511 gas water heater will be the best choice for you in terms of price, quality and performance parameters.
