Why the gas column goes off and off

The reasons why the gas column goes out may be several. It is necessary to engage in the repair of such a water heating system with the assistance of qualified specialists. However, there are a number of simple reasons why the water heater can also be turned off. Install and fix their user is able to independently.

Principle of operation

In such a wall-type water heater there is no storage tank for storing and heating water. The device has a compact size. The temperature of the water rises instantaneously as it passes through the heat exchanger. The main advantage - the provision of warm water several water points at the same time. The source of energy of such water-heating systems is natural or bottled gas. That is what explains their popularity of installation in those houses where the installation of gas equipment is possible.

All models are equipped with protective functions, in case of a problem or leakage, the geyser will shut off automatically.

Gas is cheaper than electricity, and although the cost of such units is several times more expensive, they pay for themselves during operation. In turn, the quality of this raw material must be up to standard, otherwise, the service life of the equipment will not be long. Besides the constant clogged filtration system due to the poor composition of the gas mixture, will lead to the fact that the device is constantly turned off.

The main causes of failure

It is not always necessary to call masters. There are a number of faults in the gas column, which the user is able to repair independently.

Lack of traction in the hood

As a rule, this leads to a polluted chimney. In the course of operation, combustion products fall into it, which are deposited in the form of soot on the walls. Therefore, the ventilation duct needs systematic (once a year) technicalservice. It is easy to check for the presence of traction: it is necessary to bring a lit match to the hood. In case of its adequate functioning, the flame should shy away towards the exhaust path.

Often the lack of normal traction occurs when the room is tight plastic windows are closed - they impede the flow of air. During operation, the protective relay overheats, the safety system is activated and the device is turned off.

Insufficient head

The automation system blocks the gas supply in case of insufficient water pressure. You can estimate the pressure simply by opening the taps. If it is small or completely absent, it means that an emergency shutdown in the gas column is not due to a breakdown of the device.

In the case of normal pressure in the faucet, it is worth looking for the reasons in the water heating system. As a rule, the reduction in pressure is due to filter pollution or membrane abnormalities.

Some models in the process of connection are equipped with special filters for coarse cleaning, which, clogging up, also significantly affect the strength of the fluid flow.

Coarse Filter

To correct the sources of damage, due to which the gas column wick goes out, the owner will have to:

• clean or change the filtration system;
• put a new membrane partition for the water node;
• clean the pipeline.

Ignition and instant extinction

This situation most often occurs due to improper operation of the device by users. When such a water heater is in working condition, it is strictly forbidden to open cold water to dilute hot water. This action is the most dangerous violation of its use. It can cause serious damage to the device. The temperature of the liquid is regulated solely by the gas supply.

Faulty ignition system

Depending on the models, there are three types of ignition: electric ignition (in modern versions), a pilot light, which has a small constant flame, water turbine - from pressure.

Electric ignition is powered by built-in batteries. According to the manufacturers, they are enough for about a year. But as practice shows, the service life of such batteries is less.For example, in the Bosch gas column of models W 10 KB or WR 10-2 B on the front panel there is an LED that indicates the state of the batteries. Also this type of ignition is equipped with a model range of gas columns Neva Lux. If necessary, old batteries are replaced with new ones.

If the cause of the problem becomes a wick, then it is best to seek the help of qualified professionals. They will test the functions of the thermocouple and gas control systems, clean and adjust the igniter. Often the problem, when the gas column igniter is extinguished, is solved complete cleaning of the water heater.

In the case of hydroturbine firing, for example, as in Bosch WRD 13-2 G or WRD 10-2 G, a malfunction may occur due to lack of water pressureon which it is based.

Ignition microexplosions

These unpleasant processes are only a consequence of low thrust, unsuitable for battery operation, pollution of the apparatus itself, or a very large amount of gas that is fed to the column. For self-repair, the owner can only clean the exhaust duct or replace batteries. If the problem has not been solved, then only employees of gas services can understand why the column is going out.

Contaminated Vent

How to prevent breakage

To extend the life of the equipment and ensure its smooth operation, you should systematically perform preventive actions:

• clean the chimney;
• replace ignition batteries;
• remove scale and soot from the nodes of the instantaneous water heater;
• to provide good air ventilation in the room - this is important not only for the normal functioning of the device, but also for the safety of people.

Timely cleaning and replacement of old filters will help avoid trouble associated with the operation of the water-heating unit.

These are the most common problems for which the gas column is turned off and off. As can be seen, in most cases, their owner of the device can eliminate them. If repairs are not possible, or special equipment or knowledge is required for maintenance, you should call in a qualified technician.
