Installation of gas columns: rules, approval, guarantees

Water heaters are distinguished according to consumed energy resources. In everyday life, only gas columns and electric boilers are used. If the water heater is replaced, a device with the same energy resource as the previous one is installed. Installation of gas columns, as well as any devices with such a power source, requires the intervention of the relevant services. The operating costs are much cheaper, because the use of electrical appliances is more expensive.

Storage water heaters

The household gas column of storage type copes with water heating in the best way. There are floor, flat and horizontal devices. Thanks to several available options, you can select an installation that fits into the interior and dimensions of the room. In the process of designing a water heating system, it is necessary to take into account the methods of air inflow. Forced draft is created when the devices are connected to a pipe that has been put out on the street. The natural draft requires a continuous supply of air and connection to a common ventilation outlet.

Flowing water heaters

Installation of gas flow type columns is carried out in Russia most often. The average price of such units on the domestic market is 15-20 thousand rubles. Once with the work of these devices there were small difficulties. It was necessary to monitor the flame, so as not to fade, and to regulate the supply of gas manually. Modern analogues are much easier to manage and less dangerous.

Mounting rules

Each installation of such devices must be coordinated with the gas services. For installation of the speakers with an open camera, there are technical conditions that must be observed. Install the unit yourself will be very difficult, if it was not previously. It will be necessary to link to the main gas and water mains. For this reason, the installation of water heaters of the flow type is carried out in the kitchen. But at the same time it can not be installed above the gas stove. The main requirement for installation is the availability of special hoods. Previously, such columns were installed in the bathrooms.

Replacement

You can always change an obsolete copy to a new one. For the installation of flow-through gas water heaters in apartments and private houses, it is necessary to observe the basic positions: connection to the water supply and gas pipeline, installation of the hood. If the column has already been installed, then all the above rules have been respected previously. It remains to simply mount another new unit.

Disconnect from gas and water

To dismantle the obsolete unit, access to gas and water is blocked by means of valves. First unscrew the nut of the gas hose using the adjustable wrench. A metal tube can be installed instead. After that, the hose is unscrewed from the column. If the hose is full, you can use it again. At the same time, you should not save on buying a new one. A poor-quality hose can cost much more. After access to water is blocked, the column can be disconnected from the water supply.

Dismantling of the chimney

After the pipe connecting the unit to the chimney is removed, the water heater can be removed from the chimney. Before installation, make sure that the old attachments are suitable for the new device.

We hang the unit

Installation of gas columns requires certain proportions. In the room, the height of ceilings should be more than 2 m. The vertical of the pipe in the chimney must not be less than 50 cm. When the ceiling height is 2.7 m, the pipe may be larger by 25 cm.

Connectivity

After the column has been fixed by means of hoses or PVC pipes, it is possible to connect it to the water supply system. Next, you need to check the unit for leaks. If necessary, tighten all nuts. The column is connected to the gas pipeline with a quality new or old hose. After crimping all the piping must be treated with soapy solution in order to detect bubbles and determine the reliability of the connection.

The first installation of a gas column in a private house

If the installation has not been done before, you will need to do some more complicated work. In addition to the usual rules, it is necessary to take into account that the wall on which the unit is to be hung should be made of non-flammable material. The minimum water pressure in the pipes is 0.1 atmosphere.

Extractor hood

The rules for installing a gas column require the selection of a suitable location for the hood. If a chimney or fireplace is installed in the room, you can use this ventilation space. Otherwise, it is possible to make a hole in the lid and insert an asbestos tube approximately 2 m in length. The installation is best done near the inner wall. In the absence of a landing channel, a hose pipe is used for gas water heaters.

We fix the unit on the wall

The gas column in the apartment is installed directly under the pipe. The unit must be installed at a height inaccessible to children. At an appropriate level, holes are drilled into which the fastening elements are inserted, and then the column is screwed to the wall. With the help of flexible corrugation the unit is connected to the chimney pipes. One end of the corrugation is fixed in the previously prepared hole, and the other end is attached to the column.

Connecting the device

To connect to the gas in the pipe cuts the tee. This can be done with gas welding. If there is a threaded connection, the tee can simply be screwed. Then you need to attach a gas shield. Now, note the distance between the pipe and the column. At the place of passage of the liner, fixings are cut into the wall. With their help, the pipe will stay more reliable. For this purpose, special clips with snaps are used. The pipe is connected to the column using a union nut and fitting.

Water connection

The installation of the gas columns provides for a similar insertion of the tee into the water pipe. In the same way, holes are drilled in the wall for fastenings. The Maevsky crane can be installed and used when adjusting the water pressure. Magnesium and salt filters are mounted next to the column.

First start

It is possible to carry out a test run after the gas column has been installed. The price for heating with electricity is much higher, so boilers are used less often. The gas cock opens and the fuel enters the column. Joints of gas pipes must be checked with a solution of water and soap. The leak will need to be eliminated if bubbles are blown somewhere.

Then the water is launched, the Maevsky crane opens, and all the air is discharged from the pipe. After that, the batteries are inserted into the column, feeding the display and electronic ignition. To check the operation of the system for the presence of hot water, you need to open the nearest tap. First the flow will be cold, then the heating will turn on and the head will be warm. At first, the water will not have a very pleasant smell of fuel oil. The column needs to be worked for a while, so that the grease from the pipes is washed.

Necessary tools and accessories

Installation and repair of the columns is always carried out with the use of fittings for metal-plastic, the water heater, pipe cutter, salt filter, all necessary cranes, including the Mayevsky device, spanners, drills, PVC water pins, special soldering iron for pipes, gas hoses, magnetic filter, Corrugations, screws and dowels.

Who is allowed to work with gas equipment?

Independent intervention in the system is extremely undesirable. Repair of the speakers should always be carried out only by a gas service employee who has the appropriate approval. Only in this way can you be sure of the normal operation of the entire system.

How to connect the gas stove?

This requires a special bellows hose. Wiring must not be carried out by the oven in a hot place. The hose must also not be tightened to avoid the possibility of damage. Sealing material is often used for threaded joints. To check the piping for a gas leak, you need to lubricate it with soap foam.

The insulating joint is neatly wrapped around the thread, and then a rubber gasket is inserted into the hose. After that, you can screw the pipeline to the gas pipeline. Strongly tighten the thread is not necessary. The stove is placed in place of the old one, the legs are adjusted in height so that the cooking surface is level.

For the technique you need to remove the wallpaper or put a metal sheet, if the wall is wooden. This will prevent possible fire during oven operation. The gas hose is connected to the plate using a lining. After that, we check all the connections with soap bubbles. To learn how to connect a gas cooker, it is better to consult an experienced employee of the relevant service.

Proper use of liquefied gas

If the gas stove is connected to a liquefied gas, you need to make sure that there are special nozzles on the burners. The appliances for natural gas have a significantly larger diameter of the holes. Often during installation, this feature is not taken into account, and the flame periodically extinguishes. Before purchasing hoses, it is necessary to take into account the peculiarities of the outlet of gas pipes on the plate.

Guarantee for the operation of devices

The reliability and quality of the connection can only be provided by the employees of the gas services. Self-assembly of columns and plates is prohibited by law. Unqualified interference in the operation of gas supply systems can cause explosion, fire, harm to others.

Conclusion

The technology of installing gas columns, in fact, is not anything complicated. When replacing equipment for a new part of the preparatory work can not be performed. After dismantling the old unit, it is not necessary to re-measure the pressure in the pipes, and also to remove the gas and water mains to the connection point. If the old line is still in use, it can be used when connecting new devices. Work with gas equipment can only be trusted by qualified specialists who have the appropriate approval.
