Installing gas stoves: regulatory requirements
According to the current legislation, gas systems are considered to be a zone of increased danger and interference with their functionality is allowed only employees of regional and local gas services, distribution companies or firms that have an official license to carry out such work. plan.
Among the activities requiring the participation of a gas service representative are: primary equipment connection, reconnection, scheduled and unscheduled repairs, gas meter installation, replacement of parts, etc.
The primary connection of the gas stove to the communications of the central system is always carried out only by an official representative of the gas service - a qualified installer who has permission
Even if the owners have done all the work in person, gas can be started to the burner only after the specialist has examined all connecting nodes for possible leakage and will officially give the go-ahead to activate the equipment and its further correct operation.
The owners will be able to carry out the subsequent replacement of the stove with another model independently, but they still have to notify the gas company.
Gas units prepared for installation must be registered with the appropriate service. Its staff comes to the client every six months and conducts a routine inspection of the equipment for compliance with all norms and rules for safe operation.
For unauthorized network connection or gas pipe transfer a penalty is provided.
After the initial official connection of the plate to the central communications, the owner gets his hands an agreement on the rules for the provision of gas supply services and a subscription book indicating the price of supply resource
However, if after connecting the host did not use the stove, but first he invited the master to inspect the correctness and quality of the connections, no punishment will follow. The unit will be inspected, registered as a new gas consumption point, and it can be used as usual.
Choosing a place for kitchen equipment
Before you connect a home gas stove to the central communications, choose a suitable place for it. It is desirable that the floor in the installation area was absolutely even, otherwise the cooking surface will skew and dishes will not be able to cook evenly.
The majority of modern units are equipped with adjusting legs, which make it possible to evenly set the equipment even on the floor with noticeable defects and height differences.
In order to perfectly align the slab with the floor surface, you should use the construction level. This simple tool will allow determining the best position for home appliances with millimeter accuracy.
If the model does not have an adjustment, under the edges of the lower part they simply enclose thick cardboard, a piece of chipboard or wooden plank, aligning in this way the hob relative to the level floor.
The gas stove should be installed in an apartment so that no objects or structural elements touch it.
It is necessary to provide free access to all connecting nodes so that in case of a leak or any other malfunctions, problems can be fixed as quickly as possible.
The plate is not pulled up tightly to the wall, but, on the contrary, leaves behind a small gap. Its size is usually indicated in the accompanying instructions by the manufacturer, and professionals recommend that these data always be strictly adhered to.
Preparation of tools and parts
For correct connection of the gas stove use the following tools and parts:
- flexible hose required length - universal - about 1.5 m, or individual rubber - from 1 m or more;
- ball valve from brass with nickel coating, designed to work in systems that provide subscribers with low and medium pressure natural and liquefied hydrocarbon gas;
- keys - gas and adjustable wrench;
- pad - usually sold with a stove;
- screwdrivers different type;
- sealing tape or a thread - for example, a FUM tape or a Loktayl 55 thread;
- soap solution medium concentration and a brush to check the accuracy and accuracy of the connection for leakage.
As soon as all the necessary components are at hand, proceed directly to work.
The method of connecting the plate to the system
For independent connection of the gas stove to the communication nodes use special hoses with special physical characteristics.
Upon purchase, these parts are checked for durability and flexibility, and they also look at the quality certificate in order to understand whether the proposed product meets the requirements for gas components equipment.
Connect the stove to the central gas system only directly. No extra nodes and connections are provided by the rules. If gasmen find them, the owner will immediately receive an order to reconnect
In some particular cases, the plate is connected using a metal connecting pipe, but this method is used very rarely, as it is labor intensive and has a number of inconveniences.
Types of modern gas hoses
Hose for connecting a gas stove is not purchased at the market or a remote point, but only in specialized stores or company points of sale of installation equipment.
The sellers, in addition to the product itself, provide the customer with technical specifications and issue a receipt for which the product can be replaced in the event of a malfunction.
Buying a connecting hose for the stove, it is necessary to pay attention to the labeling. The elements intended for use in gas systems, identification marks are always yellow
Water hoses are marked in red and blue. They have much lower strength and burn through gas systems 15-30 days after installation.
Today, 3 types of gas hoses are the most popular on the related equipment market. There are distinctive features between them, thanks to which the owner has the opportunity to choose the most successful option for himself.
Combining products such parameters as flexibility and strength. Due to this, the stove connected to the system can be moved without fear of breaking or somehow damaging the gas pipeline and causing a leak.
Before installing the slab, you need to inspect and determine whether it has an exit - angular (folded down) or straight. A standard hose with a standard edge is suitable for a corner, and for a straight one, a piece with a square is required.
Rubber hose belongs to the category of the most popular connecting elements. It has a high level of durability, demonstrates excellent flexibility and costs quite reasonable money.
It is made of vulcanized rubber reinforced with textile thread. It functions well in the temperature range from -35 ° C to + 50 ° C and can easily withstand a serious operational load for a long time.
The thread on the outlet of the plate should cross-section with the parameters of the connecting hose. Usually this figure is 1/2 ′
If the thread is 3/8 ′ on the unit, then for correct connection to the system you will need to use a special adapter. Almost always it comes complete with a stove. In the absence of the item is purchased in a hardware store
Rubber hose with metal braid is an improved version of the above option. The metal casing provides even greater strength of the product and almost completely eliminates the occurrence of leakage.
The product is offered on the market in the widest range and has a different length. This allows the use of this type of hose in any kitchen premises and even where the stove is used with maximum intensity.
A gas hose with metal braid can work in aggressive conditions (heat, cold, sudden changes in temperature). The metal protecting rubber from damages, possesses high anticorrosive properties, does not rust and is not afraid of moisture
Bellows hose - it is a flexible piece of metal-plastic corrugated tube with excellent physical characteristics. It is produced according to modern technologies, it is resistant to intense pressure and its drops, it is well stretched and has a surface protective shell of high strength.
The bellows hose has an unprecedented level of reliability and ensures the safe transfer of gas from the central system to home appliances. Its service life without loss of efficiency is 25 years.
In rebuke bellows products put only a fairly high price compared with similar products made from cheaper materials.
However, despite this, representatives of gas distribution companies strongly advise owners to connect slabs through a bellows hose in order to increase the level of safety in the operation of household gas aggregates.
Additional information on gas hose classification and selection is presented in this article.
Basic requirements for hoses
The connecting hose used to connect the cooker to the central gas system must meet certain requirements ^
- limited length - no more than 1.5 meters;
- evenness - the surface of the part without extensions or narrowed areas;
- no curvatureknots and twists;
- durability - The service life can be obtained from the seller or from the quality certificates confirming the compliance of the hose with the standards generally accepted for gas equipment;
- no cracks, cuts, rust and other visible damage.
Another important point to consider is that the hose should under no circumstances touch hard, sharp corners and materials subject to burning.
It is better if it is positioned loosely behind the slab, without adjoining to any surface. Then the owners will be able to easily control his condition and will not miss the moment when it is required. hose replacement.
Connecting the plate to a centralized system using a metal pipe is a very reliable, but already outdated method. Today it is rarely used because of the laboriousness and the need in some cases to use specific professional equipment.
At pipe connection of the plate to the centralized communications supplying the gas resource, copper or steel pipes are used. They have a high level of durability and guarantee a clear, reliable connection.
The main disadvantage of connection with pipes is that in the future the stove cannot be moved away for cleaning or moved to another place without resorting to disconnection from central communications.
Types of seals for gas systems
So that the nodes connecting the stove to the distribution gas system did not leak and for years provided tightness of all communications, use special seals, for example, Loctite 55 or FUM tape.
Gas service elements are not recommended by gas services personnel. Their performance is too weak for such an impressive daily load.
Thread Loktayt 55 - practical, modern material designed specifically for reliable fixation of connecting sections in communication networks of varying degrees of complexity.
It is a sealing fiber made from complex threads of high strength, is supplied in plastic containers and has a different length (from 12 to 160 m, depending on the package).
Thread Loktayt 55 - the universal element providing to threaded connections reliable instant sealing even with a strong pressure. The certificate allows you to use the product in gas systems without restriction
To create a tight joint, I manually wind the thread onto a threaded section of pipeline fittings. It is instantly fixed in place and no longer changes its position.
The second reliable sealing element is tape FUMmade from fluoroplastic 4D.
There are three types of FUM tapes on the market:
- Mark 1 it is supplied with additional greasing on the basis of vaseline oil. It is used in industrial systems and communication networks with caustic, aggressive media.
- Mark 2 does not have a lubricant and best of all manifests itself in complexes operating on various oxidizing agents.
- Mark 3 It is produced using edge fragments of the first two types and is suitable for both industrial and domestic purposes.
It represents the thin threads laid in a film.
FUM tape demonstrates high anti-corrosion properties, shows good heat resistance and does not emit toxins during active use
Tape FUM allows you to make a strong connection of pipe elements, which for many years will provide the system with complete tightness. The warranty period for storing the tape in a container is 13 years.
Phased gas stove connection process
Before you connect a gas stove in a house or apartment, they find the most convenient place for it. Then remove the original packaging, screw adjusting legs to the bottom of the unit and place the module in the selected area.
Between the equipment and the wall leave a gap corresponding to the dimensions specified in the accompanying instructions for household appliances.
Near one of the sides lay the construction level, and then, using the adjusting legs, expose the slab as smoothly as possible. First, gently twist the legs on one side, and then on the other.
After all these events, the unit takes a tough position, does not swing and does not roll either to the right or to the left.
Next, connect the equipment with a flexible hose. To do this, from the outside, a layer of a special sealant is carefully wound onto the threads of the hose fitting. (Loktayt 55 thread or FUM tape, designed to fix individual sections in communication systems).
This will ensure further reliability and complete tightness of the complex.
Linen gasket elements are not used for compaction in gas systems, since their physical characteristics are much lower than those of FUM tape and Loktait yarn 55
The hose fitting with a seal is screwed into the gas valve on the lowering, and the second open edge of the hose is screwed into the outlet thread of the gas stove.
When home appliances are connected for the first time, they turn to a specialized service and invite a specialized wizard with relevant knowledge and the right to activate the equipment.
While working with gas systems in the room, the windows are kept open and closely monitored so that there is no open flame nearby.
In the presence of a gas service officer, all connection points are treated with a medium-density soap emulsion, the valve is opened and the system is tested for possible leakage. If the gasman does not detect any problems, they start using the stove in standard mode.
Safety rules and tips
Self-installation of a gas stove is carried out in strict accordance with the safety rules governing actions in contact with gas networks.
- The flexible hose connecting the unit to the gas supply system is placed in sight in an easily accessible place and by no means overlap. This item should always be available for inspection or scheduled replacement.
- The gas hose is made in strict accordance with generally accepted regulatory documents, not exceeding the allowed size of an inch.
- The connecting sleeve itself is not painted as the paint damages the surface and contributes to its premature cracking. If the appearance of the sleeve is not too aesthetic, it is masked under self-adhesive paper.
- Directly connect the hose only to the supply valve and gas stove. The adapter is used only in the case of non-standard threaded connection of one of the outlets.
- Prior to the installation of the gas stove, they shut off, turning the shut-off valve on the branch pipe from the supply riser up to the stop, and notify everyone in the room about the work being done.
- When installing, use only special tools, consumables and components designed to work with gas fittings.
- All pipes that are open during the connection are immediately plugged. For lowering as a gag use a thick wet cloth. Water, absorbed into the fabric, gives the material a high level of gas tightness.
- For the temporary closure of the flow pipe with 1/2 ”threads, take a cork from the wine bottle. Its narrowed edge is cut in the shape of a cone, treated with sandpaper and tightly "screwed" into the tube hole. If the part is stuck, remove it with a corkscrew.
Upon completion of the work, the coupled areas are coated with a medium-concentration soap solution, the gas shut-off valve is opened and the system is tested for leaks.
If the soapy liquid starts to bubble, the gas is closed again and the joint areas are brought to full tightness.
When a hiss is heard during a test run or there is a smell of gas, the valve is immediately closed, the windows and doors open and the emergency gas service team is called.
Sometimes when connecting or transferring a plate it may be necessary gas valve replacement. This work is carried out only by representatives of the gas service with a preliminary gas shutdown throughout the riser.
