Why does the gas in the column burn with an orange or red flame

Repair and installation of the gas water heater, as well as other equipment working with gas, is carried out only by a specialist. But there are a number of problems that the owner can cope with on their own, for example, if the gas water heater does not ignite.

Does not light up, the gas column slams

Boiler design simple enough. The burner of the device is supplied with natural gas and oxygen from the air in the room. At the same time, when turned on, the gas mixture is ignited, the gas ignites and gives off heat to the water.

But even with such a simple mechanism of work, the most different breakdowns... The most common are the following:

  • the device does not light up, clicks;
  • does not turn on when opening the tap;
  • ignition is performed, a flame appears in the burner, but after a short time the burner spontaneously goes out;
  • the column claps during operation, hums strongly, sometimes even vibrates;
  • the device works, but the water does not heat up enough;
  • water drips from the column while maintaining the integrity of the case;
  • when turned on, there is a smell of gas.

The consumer can cope with some malfunctions himself. But it is important to distinguish what can do it yourself, and in what cases is it necessary invite a specialist.

Most of the breakdowns of the gas water heater should be corrected by a specialist.

Even if the owner of the apartment has carefully studied the instructions by virtue of the profession and has a good idea of ​​how such a device works, he has no right to overhaul and replace elements.

What can you do / check yourself

Most often, problems arise when the gas water heater does not light up. The reasons:

  • Poor cravings - this difficulty is not related to the column, but with chimney... The latter is a mechanical device; special permission is not required for its repair. Most often, traction is lost if an object is stuck in the chimney or it is clogged with soot. To check its operation, you need to open a window and light a match near the opening of the chimney. If the flame deviates towards the exit, there is a thrust. If not, you need to call the chimney sweeps, because you will not be able to clean the pipe yourself.

    Checking draft with an anemometer
  • If the appliance is equipped with automatic ignition, it is possible batteries fell into disrepair. Check the operation of the power key. If everything is in order with it, replace the worn-out batteries with new ones.

    Battery compartment
  • The burner goes out when weak water pressure Is the security element of the system. Compare the pressure of cold and hot water from the tap. If the cold one flows weakly, the reason is in the water supply system, if not, in the water heater. The reason may be clogging of filters, water lines, deformation of the membrane. You need to solve the problem in stages. First, they call the utility service to find out how the water is supplied to the line. If it is within the standard, they try to clean it: replace the filter in the mixer, wash the filtering device, clean the boiler from soot. If the malfunction persists, invite a specialist to flush the pipes.
  • When the gas water heater slams when the water is turned on, this issign of normal operation... In the short time required for ignition, the gas accumulates in a small volume. If there is no sound, this indicates that there is no gas.First, they call Gorgaz to find out if the line is being repaired. If not, they turn here for help.

The second most common problem is turning off the water heater after a short work or insufficient water heating.

  1. If the device works for some time, then goes out and turns on again only after 15–20 minutes, most likely the case is in the heating sensor... It is overly sensitive or the unit is in an overly warm and stuffy room. In the first case, a new sensor is installed; in the second, it is enough to ventilate the kitchen well.
  2. If the speaker works well, but suddenly turns off for no reason, it may be in isolation... The boiler can be repaired by the service department.
  3. If the water does not heat up well, the reason is insufficient power apparatus. You need to buy a new one or supply hot water to the kitchen and bathroom alternately.

It so happens that a newly installed column does not provide hot water. One of the options - swapped hoses during installation... It is necessary to switch the hoses by carefully studying the instructions for the device.

When and where to go

The specialist must have permission to work with gas equipment

In certain situations independent actions are excluded.

  • If during piezo ignition there is a strong gas smell and does not disappear after starting the fire, you should immediately turn off the device, turn off the blue fuel supply and open the windows. Gas leaks are extremely dangerous. You need to call the emergency service.
  • If the ignition is not felt no smell, but the burner does not light up, this indicates the absence of gas. Contact the gas utility for advice.
  • The speaker claps, clicks and whistles when operating for two opposite reasons - excessive pressure in the gas pipeline and insufficient... More often this is due not to the pressure in the gas supply, but with burner malfunction... It needs to be cleaned and configured. To do this, call the service center.
  • The column may not heat well due to rupture or wear of the diaphragm... It does not hold cold water, and the latter mixes with hot water. As a result, the water at the outlet turns out to be warm or cool. Only a specialist can fix this breakdown.
  • The column is leaking most often due to loose connections of hoses or wear of the water part... In the first case, replace the rubber gaskets, choosing better ones. Damage to the heat exchanger can be so serious that it will be more profitable to buy a new unit than to repair an old one.

Ask a Question
It is necessary to invite a service worker or Gorgaz in all cases related to breakage and replacement of parts. During installation, the device is sealed, which serves as a confirmation of the warranty. If you repair yourself, the seal is damaged and then the warranty is invalid.

Column gas color

For methane or propane to ignite, it must mix with oxygen in a certain proportion. Depending on this, the color of the flame will change. By its shade, one can understand whether the device is working normally or intermittently.

  1. Blue the color of the fire indicates that the mixing of the gas from the pipeline and the oxygen is in the correct proportion, the gas pressure is sufficient and the burner is functioning normally.
  2. Yellow - says that the fire burns not only gas, but also particles of soot and soot. Dust adheres to the surface of the igniter and burner. It does not interfere with the passage of gas, but it creates an obstacle for the air. The burner mixes gas with air in the wrong proportion. Often, a yellow flame is observed in a new column in the first 3-4 months of operation. This is due to the fact that factory grease remained on the ignition group. It forms an oil film to which dust adheres.
  3. If the gas burns orange flame, this means that the contamination of the nozzles has reached critical values. The burner needs to be cleaned urgently.Orange flames are often accompanied by smoking, and the lights can bounce off. But if such a phenomenon is observed for the first time, you first need to check the position of the damper. If it falls off or closes, the air supply is interrupted.
  4. Red color indicates danger. When methane burns, a certain amount of carbon monoxide is always released. As long as his concentration is low, there is nothing to worry about. But if the tongues of flame become red, this is an indication that the fuel does not burn completely, too much carbon monoxide is formed. The column should be turned off immediately and the room should be ventilated.

You can only clean the burners yourself. All other work must be performed by a specialist.

How to prevent malfunctions

Each model has its own operating characteristics, they need to be studied

To prevent damage to equipment, you must perform rules for its operation... It is important to observe both the general recommendations for handling gas appliances and the manufacturer's instructions.

Study instructions

A detailed study of the instructions in most cases guarantees the normal operation of the column. The document details rules for handling a specific device taking into account its type, design and purpose.

For example, columns with a constantly burning wick should be turned on long before using hot water. This is usually done in the morning so that the tank has time to warm up a large volume of water. Automatic units start immediately after opening the hot water tap.

Column firing is performed using different methods: piezo ignition, electric ignition, matches... And in each case, the algorithm of actions is different.

Setting up the gas column

IN old storage boilers the water temperature is regulated only by changing the intensity of combustion. To do this, you need to disassemble the housing and tighten the nuts on the back of the gearbox.

IN flow devices the temperature is changed by changing the rate of passage of the water.

If the device is controlled manually, the parameter can be adjusted using the levers. The left one is usually responsible for gas, the right one is for water speed. It is used to determine the temperature of the liquid and the burner response limit.

Set the required heating on the column with electronic display much easier: just select a mode from the list.

The setup of the automatic device is carried out by a specialist during installation.

How to take care of your equipment

There are a number of general provisions that should be followed when using speakers of any type and design. The rules are as follows:

  • in the absence of draft in the chimney or in case of reverse draft, it is prohibited to start the device;
  • good ventilation is required for normal operation of the boiler;
  • you cannot turn on and light up the device without studying the instructions;
  • it is strictly forbidden to change the design of the column;
  • you should independently monitor the cleanliness of the chimney, ventilation, mixing filters and other devices;
  • in case of malfunctions, contact the service center or gas service.
