Cleaning the gas column with your own hands. The device of a gas column

The gas column is relatively affordable and simple to construct. It helps to gain independence from the central water supply. After all, quite often central networks sin by interruptions and planned outages of water for a long time. In order for the column to last as long as possible, it must be serviced from time to time, periodically subjecting it to cleaning.

Reasons for the need to clean the column

Cleaning the gas column is required due to the fact that some important structural components of the equipment are covered with scum. The task of the column is to heat water by burning gas. The device can be attributed directly to two types of household appliances - water and gas.

If it is a question of the gas part of the device, then soot accumulates there, a deposit is formed, from which the unit must be periodically released. Need to clean up more and joker, which are the holes of the ignitor and the burner. But scum is salts that are insoluble in hard water. They fall out as a deposit when the water evaporates and are on the walls of the pipes of the column.

As a rather important problem is the scum, which prevents the heating of water. If the elements of insoluble salt are found in the channels of thin tubes, this will reduce the efficiency of the equipment, sometimes making this function impossible.

Symptoms indicating the need to clean the column

Cleaning of the gas column should be carried out if:

• Equipment does not turn on or off;
• The thermal protection sensor is constantly activated;
• Decreased the efficiency of the device;
• The output head is rather weak.

The need for cleaning is indicated by the fact that if the column is disconnected after some time after starting work. At the same time, you should make sure that water and gas are ingested. If you notice that the thermal protection sensor is constantly working, you can be sure that a thick layer of scale has accumulated inside it, which has a porous structure and has heat-insulating characteristics, this fact interferes with normal cooling.

Cleaning the gas column is required in the case when the efficiency of the device has decreased. At the same time, the water began to heat up more weakly. This is true for the case when the water pressure at the outlet became sufficiently weak, which indicates that water simply can not break through channels blocked by scum. Before starting any operations with the equipment, shut off the gas and water supply valves.

Cleaning the water intake unit

Cleaning of the gas column should be carried out in the area of the water intake unit. It is located at the entrance, has a screen filter to prevent clogging of the tubes of the heat exchanger by coarse-fractional elements of sediment and rust. Before cleaning the gas column, it is necessary to remove the water intake unit from the housing, and then unscrew the connecting screws, which will open the housing.

It is necessary to clean the filter, and then rinse it well under a strong head of water. The membrane should be checked, it should be flat. If this is not the case, and the element has concavities, this indicates that the node has exhausted its resource and is subject to replacement. To do this, you can use a modern silicone model, which has a much longer period of operation. After the gas column has been cleaned, it is necessary to close the cover of the water intake unit, tighten the screws and tighten them one at a time.

Carrying out cleaning of the gas burner

Cleaning of the gas cylinder burner can only be carried out in the area of the nozzles. If you compare the burner to the water main, the latter you can disassemble yourself, but the first one should be entrusted to the specialists of the gas service. To remove soot from the nozzle of the burner, it is necessary to clean it with copper wire.

You can remove the soot with a metal brush. The column is checked for gas leakage, for which a soap solution is prepared, applied to the junction of the pipes and the unit. If bubbles begin to form at the junction, this indicates a leak. The crane should be shut down and called for service specialists 104. Cleaning of the gas column from the scale is not necessary if timely preventive measures are taken. To do this, use filters during operation and try to reduce the hardness of the water used.

Possible reasons for the ignition in the column to go out

If you notice that the fuse of the gas column is extinguished, then a possible cause should be identified, this may be due to the fact that:

• There was a blockage of debris and dust;
• There is no draft in the chimney;
• Burned or worn thermocouple;
• Smoking occurs due to lack of air;
• External air flows predominate;
• There was a malfunction of the traction control;
• The solenoid valve has failed.

One of the most common causes of the above problem is the malfunction of the thermocouple. It has the form of an element of a safety device, which is used to shut off the flow of fuel when the equipment is unstable.

If the fuse goes out, the thermocouple detects a lack of heat and turns off the gas. But if the thermocouple has a burnt tip and is loose from the effects of fire, this too can cause the above problem. Sometimes it happens that the holes of the gas nozzle on the ignitor have a small diameter, which is why they are clogged with dust and debris, preventing normal combustion.

The device of a gas column

If you want to clean the equipment, you should be aware of the device of the gas column. Usually it consists of a metal case that looks like a kitchen cabinet. The pipes for the water supply and fuel supply are fed to the column. The design assumes the presence of:

• Heat exchanger;
• A pilot burner;
• Main burner.

Depending on which type of ignition is used, after the opening of the water tap the column valve starts running, which passes the flow of fuel into the pilot burner, and it ignites the main one. A sufficiently large amount of heat is released when the gas burns.

Heat passes through a heat exchanger made in the form of a spiral. Once the water has heated to the desired temperature, it is fed through the outlet pipe and goes to the open faucet. Studying the device of the gas column, you will understand that it also has a chimney, which is necessary to remove the products of gas combustion from the room.

More about the device

Depending on which igniter is used, the column may have electronic, manual or piezo-ignition. The second option is obsolete, because it involves the use of matches to ignite the ignitor. The main column in this case is used only after it is possible to turn the special handle. Models of modern gas columns almost always have an electronic ignition, because it is easy to use, practical and safe. Such systems are able to operate in an automatic mode and do not assume the need for human intervention.

Conclusion

Cleaning the gas column with your own hands can be carried out also in the area of the heat exchanger. To do this, disconnect the water outlet and water inlet pipes into the heat exchanger. If the cleaning has not been carried out so regularly, the nuts may be clogged with scum. In this case, you should use a special liquid, which you can buy at the car store.

The oil is inserted into the fastener connection points. After 30 minutes, the nut can easily be turned off. Once the heat exchanger has been disconnected, a descaling agent must be poured into it using a funnel. Sometimes the cleaning is carried out with a stem 9% vinegar, which is previously diluted with water in a proportion of 1 to 3.
