Why does not turn on the gas column

In many apartments there are gas water heaters with which you can heat water for different needs at any time - this is very convenient in all respects. Therefore, if the gas column suddenly for some reason does not ignite - this causes a certain discomfort. Why is this happening and how can I fix the situation?

Violation of thrust

If there is no stable thrust, the product simply cannot function normally - there is no ventilation, the flame is extinguished due to lack of oxygen. New models are equipped with special thrust sensorwhich controls the exhaust of combustion products - if it is absent, the gas does not ignite. This method protects the product.

When the chimney is not working, it is necessary to inspect the chimney, but the user will be able to check only the collector going to the wall - then the scope of specialists in the maintenance of ventilation and chimneys, you need to call the city service.

No head

Domestic products are very popular among Russians today: the Neva Transit or Neva Lux gas column. These appliances can run on natural or liquefied gas, so they are used in rural areas where there is no main connection yet. The lack of proper water pressure leads to the fact that electric ignition does not take place, and even such a reliable product as the Neva Transit will not work. If water flows from other taps under normal pressure, clogged filterinstalled at the entrance - so the gas column Neva sometimes does not turn on. Clogging can also occur in the supply pipes, especially if the user lives in an old house.

Important! You can clean the filter yourself, for this you need to unscrew the nut at the top of its body and clean the mesh.

When the pressure is weak in the entire water supply system, then you need to call Gorvodokanal to resolve the situation. With constantly poor pressure, for example, when staying on the upper floors in a high-rise building, it is necessary to put pressure boosting pump.

Gas pressure

The product may not turn on due to poor pressure in the pipeline. It is easy to check it - turn on any hotplate on the stove, if the pressure is low, then immediately call gas serviceperhaps there is a leak somewhere that is fraught with an explosion. Independent repair is out of the question - these problems are solved only by gas equipment specialists who have a special permit.

Attention! If you have a Vector gas column installed, in case of any refusal, call the service, the experts do not recommend independently resolving even minor problems, because there is a real danger of fire and even an explosion.

Problems with ignition

If piezoelectric ignition is installed in the gas column, then a frequent problem is insufficient power of the batteries. Better to use alkaline batteries, they have a greater charge and longer exploited.

We must remember! The unit for installing batteries is located at the bottom of the product; replacement is easy, which is easy for users.

When an electronic type ignition is installed in the gas column, its serviceability is checked by the presence of a crackling triggering device. If there is no spark, then check the contacts or replace the batteries, because with a weak discharge, the gas-air mixture in the burner will not ignite. For users with a igniter and a piezo element, the product should ignite immediately after opening the burner valve and pressing a special button. When the pilot light cannot turn on, it is necessary clean the jet hole using fine steel wire.

Ignition system based on work electric generatorwhich runs the water flowing through the pipe. The whole system consists of a microgenerator and an electrical circuit: water starts a device located in the water inlet pipe, current is generated, the system is triggered, creating a discharge for the spark - the column is lit. If the generator for some reason does not work, the gas will not be able to catch fire, because there is no spark for its ignition,but it’s better not to interfere in such a complex system yourself - invite a professional master to repair it.

Blockages and their elimination.

We have already written how to clean the filter installed at the entrance to the product, we only note that with a strong deformation of the grid due to the abundance of hard foreign particles in tap water, it is simply changed. With long-term operation, given the rigidity of our water, the heat exchanger of the product and its pipes often become clogged, and then the gas column does not ignite when all other elements work properly.

When cleaning is required due to the fact that water does not pass through the pipes of the product, it is necessary to disassemble the device, disconnect the heat exchanger and place it in a large container filled with a special composition of hot water and chemical ingredients that neutralize various deposits.

On a note! When cleaning the heat exchanger from carbon, in the pipe system, carefully pour citric acid to the top - in 40 minutes all internal deposits are eliminated.

If the water supply is very hard water with an abundance of impurities, then a special filter is used to protect the column, which not only detains the particles, but also softens the water.

There may be a blockage in the burner - this can also be the answer to the question why the gas water heater does not light up. More often the burners are clogged burning waste - accumulation of soot. They are cleaned during cleaning of the heat exchanger so as not to disassemble the product again, but to do everything at once. While the heat exchanger "accepts hot water procedures", it is possible to clean the burners with improvised means, but it is better to do this outdoors - soot has the property to pollute the whole surrounding space.

Gas block diaphragm

Turning on the gas column is not possible if membrane rush made of elastic and durable rubber: depending on the pressure of the water, it directs the flow of gas into the product.

Repair is difficult - to find a spare diaphragm, which is made of durable and elastic rubber, is very problematic in retail, and the cost of it from dealers is very high.

In addition to the diaphragm, you should check the entire gas block of the working column, there are a lot of parts, and each can break.For disassembly and subsequent repair there are many recommendations that can be found on the Internet.

Electronics Failures

All models of modern devices have a lot of electronics: various sensors and blocks that control not only the thrust and stability of combustion - they can regulate the temperature of water heating. If the product is malfunctioning, then this is a sure sign that there are malfunctions in the electronics, but the professionals must do the repairs.

Most of the faults can be resolved on their own, but in difficult cases, the help of specialists is needed. Whenever you work with gas equipment, you need to remember the safety rules and strictly follow them. To help home masters in carrying out minor repairs, here is a video:
