How much is the installation of a gas column?Removing and replacing the geyser hands of experts will cost an average of 3,000 to 4,500 rubles.It is in Moscow, in the regions will be cheaper.The amount is not astronomical, but, nevertheless, still it is a pity to give it for the work that you can easily do yourself.And all would do, but in this matter there are so many nuances, if ignored, could swipe at the user's pocket.
What are the nuances?What are the general rules and regulations govern these types of jobs?And you know the basic provisions are obliged to, because it is not water, with which you can experiment.Gas gas, negligence and carelessness against him end very badly.In this article we consider the order of works to replace and install a gas water heater.Consider the steps, as well as what you can do yourself, and what is better left to the representative of the gas industry.

norms and requirements governing the installation of gasSpeakers
Note!Outset that all kinds of work related to the gas supply, ie,supply of gas pipe installation tees, stopcocks on the gas pipe, etc.carry only organization with the special license.Ignoring this situation in the best case, would lead to substantial fines and severe headache.
All installation of the gas column can be divided into two categories:
- installation with "zero", ieit was not, but you decided to put;
- replacement of the old to the new column.
In the first case the project needs and the supply of the gas pipe to the location of the future of the water heater.All these works are the inheritance of gas facilities in your area, or company that is licensed for a specific activity.Without this we can not do.Do not try to do in this case is that - either alone.It's not smart, becauseown risk life and property, and when a gas column in the apartment, and others at risk.And with state-of these games to play not with your hands, not the weight category.Therefore let these people work authorized by law for this type of activity.
If the project is ready, all in unison while doing part of the work properly, you can save a considerable amount.Any work that decide to implement their own, should be carried out accurately according to the requirements of the approved project, if this is not done - gas economy will not take into operation the gas water heater.
Note.All installation gas units will be made only when the project will get all the necessary permits and approvals.
All regulations setting geyser subject to the following acts:
- SP 42-101-2003 "General provisions for the design and construction of the gas distribution systems of metal and plastic pipes"
- SNIP 42-01-2002 distribution system
Whatever weary the reader with a number of clever verbiage, we present the basic rules of installation of a column that apply to the intended installation site:
- room in which the heater is installed should be of not less than 7.5 m3.
- room must have ventilation (ventilator, window, etc.).
- ceiling height in such a room should be at least 2m.
- room must have a chimney with a diameter of at least 120mm (the "Duszniki" to those in the apartments do not apply).
- pressure in the water should be at least 0.1 atmospheres.
- not install geysers in the bathrooms.
- column is mounted on the wall of noncombustible materials is prohibited installation of a gas cooker and at a distance closer than 10 cm to it.
Thus those speakers that are installed in bathrooms in accordance with the technical standards in force at the time of installation, it is allowed to operate in the future.That is, the law clearly does not prohibit its further operation.So the new and replacement does not prohibit.And it does not require the transfer by the user.
If all these requirements for the installation of the gas column feasible, then you can order the project.The exact location of installation and other data will be displayed in the project.
Dismantling of old column
Since the basic requirements and standards in general considered if all the matches - you can begin to replace the water heater.And should start with the dismantling.This can be done by hand, saving it from 300 to 800 rubles.
start with overlapping access to the gas column, closing the valve at the end of the gas pipe.Using an adjustable wrench or open-end of the appropriate size unscrew the locking nut of the hose (rare, but found a way to supply gas with a metal pipe).Unscrewing the hose gas pipe damage is difficult, but when "ancient" method of connection, ie,a segment of metal pipe, is quite real.Especially if the connection over the years to paint over paint.In this case, do not use excessive force to remove the paint, use a modern solvent specifically for this work.Spinning, hold a second gas pipe wrench, so less chance of damage.
Once disconnected from the gas supply pipe must be removed hose (pipe) from the place of entry into the column.If the hose is not so long ago changed his condition is satisfactory, it can be reused when you connect a new speaker.If there are suspicions about the reliability of the hose - buy a new one.When buying take sertefitsirovany and proven hose still a gas and buying cheaper hose reputable manufacturer is not appropriate.
next action to dismantle - disconnect the water supply system.If the air valves are provided to disable the column, overlying.If this is not possible, shut off the apartment.In the case of the latter option, before installing the new faucet speakers acquire two entry and exit from the water column and replace the pipe at the point where it will be connected.In the future, this will facilitate its maintenance.
Once disconnected from the water column remove the connecting pipe from the output of the column and remove it from the chimney.The column is disabled, it can now be removed from the wall mounting.The site is free for the installation, you can install the new unit.
installation and commissioning of the gas water heater
During initial installation and connection checks, with the act of registration of the gas water heater is better to entrust gasman.If you have an old column - you can make all the work himself.But there are two pitfalls, if in doubt about its ability to properly install the gas column - trust specialists purse will be somewhat thinner - but the nervous system remains unaffected and, ultimately, the benefit will be for you.
If decided to do everything yourself, you will succeed, most importantly do everything slowly and steadily.But even if no representative of the gas industry can not do, he must register the column.The best option is probably a situation where all the work on the connection you made yourself, except for work connected with the gas.In this case, save a considerable amount of gas and service problems should arise becauseconnection to the gas pipeline will carry out their representative.This option consider.
Tools and materials
Before starting work, you must purchase and have the following materials:
- or corrugated galvanized pipe, not thinner than 1 mm.When it comes to the column - is remarkable.If not, to measure the diameter of the outlet boiler column or look in the manual and get proper pipe.
- Purchase ring - socket arrangement for entry into the chimney, as to the size of the corrugations.
- If you plan to install a gas column in the house, and the necessary equipment chimney need to asbestos or metal pipe with a diameter of at least 120 mm possible.The length is not less than 2 meters, you can more - will be better traction.
- gas sample hose, hose size will depend on your environment, ie,distance from the end of the gas pipe prior to entry into the column.Pay attention to the type of thread on entering the column must fit the hose must match the type of threading the outer / inner diameter and ½ »or ¾».The diameter of the fixing nut on the hose ½ »and if the input to the column ¾» need an adapter (coupling).
- Supply Pipe Fitting better prepare in advance, so you will need only two connecting hoses, the desired length.You can make connections using plastic pipes as you will be more comfortable.In the latter case, determine whether it is necessary to agree on the size of the sleeve and the pipe connection points and threads (internal / external).
- Plugs for mounting speakers on the wall.
- If the house is not set pre-filter, we recommend you install.The quality of water will directly depend on the life of the new unit.
tools you'll need:
- Depending on the complexity of the work and material - with a set of hammer drills and chisels, a drill with a drill on a ceramic tile.
- wrench (2 pcs.).
- wrench 27/30 and 32/36.
- Tow and sealant such as "Unipack".
Installation and testing of the new unit
As used herein, is meant that the supply of water and the presence of the chimney is already implemented.The installation location of the gas column, mark the point to install the mount.You need to calculate the height of the column of accommodation so that would be the connecting pipe (flute) had a vertical length from the exit of the column to the outlet at least 50 cm if the ceiling height exceeds 2.7 m - 25 cm. At the same time, the mounting height of the gas column is notIt should give children access to the device.Just to measure the distance between the holes for mounting on the body of the column.After the calculated location of the dowels using a punch or drill, depends on your environment, make the holes and set the hooks.The column can be hung on the wall.
Now, with connecting hoses or PVC pipes are connected to the input of the release of water column.Using a hose handy in that the joints do not need to tow or tape FUM.Consistently connect the cold water tap with the introduction of the gas column is indicated in blue.In the same way we connect the output of the hot water tap (marked in red).Open the faucet hot and cold water and observe - whether we have all sealed.If you do find a leak, carefully locking nuts booster hose.Without further diligence, since it is possible to crush the rubber gasket - sealing.Connecting via the pipe will need to roll out in the spill area and twist tow with a sealant or tape FUM.
Once achieve water pipe leak can go two ways: either call gasman, or installing a gas column with his hands in full.You decide.
If the second option, then take the gas hose and screwed to the gas valve.Thereafter, the other end of the hose connects to the input of a column.Hold effortlessly whatever crush asbestos fabric gaskets.Take the soap solution, smear "from the heart" the joints around the perimeter, open the gas valve and carefully observe whether the bubbles.If there is a - a little booster nut, and then smear.So until then, until we achieve a complete seal.
So, we have a tight connection of plumbing and gas.The next step is to install the sleeve.Here all much easier to dress the one hand to the output column, inserted into the other outlet of the chimney.
Insert the batteries in the column, open the hot water tap and adjust the water temperature according to the instruction manual of the column.We use.
Finally.Usually in large stores organized and service connections.Take an interest in buying, how much it will cost to connect them to a specialist.It will be cheaper, or even free, and the issues with the warranty on the column does not arise.Yes, and registration will take place in the gas sector without unnecessary friction.
If this is not available, still recommend connecting the gas hose to entrust gasman (the cost of installation of the gas column in such a connection is several times less than the complete dismantling and installation), and he was pleased (the coin will work) and you no complaints.Plus warranty intact.But to solve certainly to you.
