Which gearbox for a gas cylinder is better. Types, device and adjustment of the gas reducer

The installation of a gas cylinder must comply with the requirements of the "Labor Protection" and "Rules against fire safety».

Installation of a gas cylinder in the house

Gasification of basement floors and cellars is prohibited. When installing a gas tank in a house, you must follow the rules:

• the gas vessel must be installed strictly vertically
• it must be available for inspection and replacement,
• it must be flush with the stove at a distance of at least 0.5 m from it and 1 m from the stove or heating radiator,
• when located opposite the furnace door - at a distance of at least 2 m.

In residential premises it is allowed to store no more than 10 liters of combustible flammable liquid in a closed container. No more than 3 liters of such liquid can be stored in containers made of non-flammable and unbreakable materials. It is highly recommended not to store containers with flammable gases in kitchens, residential buildings, apartments and rooms, escape routes, attics, basements, balconies and loggias.

Rules for installing gas cylinders

The basic rule says that self-installation gas containers is prohibited. Repair, replacement, rearrangement must be carried out by a qualified specialist. According to the rules, the installation of gas vessels must be carried out in a pre-ventilated room. On the street, the tightness of the valve seals is checked, for which the stem exit from the valve is treated with soap, then the transport plug is removed and the fitting hole is soaped with the valve closed. The operation of gas vessels is prohibited if the bubbles come out through the soapy solution. If no leaks are observed along the stem and fitting, you can bring a vessel with gas into the room and connect it through a reducer to a gas appliance. The stem seal must then be checked for leaks and threaded connection with the valve open and the taps closed after connection. To do this, also apply a soap solution. If bubbles do not come out, the gas appliance can be used. If a gas leak is observed, close the valve, take the gas container outside and call the gas emergency dispatch service.

Installation of a gas cylinder in the country

This procedure must be carried out in compliance with the requirements of the operating and safety regulations. Gas tanks should be located outside buildings in outbuildings made of non-combustible material near a blank wall section (under casings covering upper part with gearboxes, or in cabinets), no closer than 5 meters from the entrances to the building, basement and basement floors. Cabinets and outbuildings must be locked, ventilated and labeled “Flammable. Gas". At the entrance there should be a sign “Flammable. Cylinders with gas. Installation must be carried out by qualified specialists from the gas services, in accordance with the regulations of the gas industry.

Installation of household gas cylinders

Installation of gas tanks should be carried out by specialists of gas services. It is necessary to place and operate such installations, which have in their composition gas containers in an amount of more than two pieces, in accordance with all the requirements and standards specified in the laws in force. this moment normative documents regarding safety in the existing gas facilities.

Norms for installing a gas cylinder

The gas supply system must comply with fire safety and explosion safety standards during operation. Outside the house, gas vessels should be located in a metal cabinet near outer wall Houses. W The cafe must stand on a base of non-combustible material, the top must be at least 0.1 m above the planned ground level. The distance between the cabinet and the windows and doors of the first floor must be at least 0.5 m, from the doors, windows of the basement and basement rooms, well, cellar, cesspool- not less than 0.3 m. The gas pipeline from the gas tanks to the house must be introduced directly into the room where the gas equipment is installed. Gas containers placed inside the house should be installed in the premises where gas-consuming appliances are located. Installation is not allowed in the basement and basements, rooms without ventilation and natural light.

Installation of a reducer on a gas cylinder

The most reliable are considered gas containers equipped with valves. The valve connection looks like union nuts. Reducers for gas tanks are designed to reduce the pressure entering the vessel with gas and maintain it at a constant level automatically. They are also used in gas-plasma processing. The reducer fitting is connected to the main gas pipeline hose, the hose is fastened with a clamp tightened with a screw. The valve is connected to the reducer by tightening the threaded connection of the valve fitting and the union nut of the reducer. The nuts must be tightened with an open end wrench. A disposable gasket is installed between the nut and the fitting. This device is connected to gas containers equipped with valves by putting it on the neck of the gas vessel. A special sealing ring is installed between them. When the gearbox is put on the valve neck, the ring of the locking mechanism is tightened on it. The ring is released after the gearbox is seated in place. union nuts made of bronze, since when this material strikes the metal, sparking does not occur.

Installation of a gas cylinder on the street

With this installation, the gas tank must be located in special outbuildings made of special non-combustible materials and located near blind walls. You can use special cabinets and casings that cover the gearbox and the upper part of the gas tank. These extensions should be located at a distance of at least 5 meters from the basement and basement floors and from the entrance to the building. Special cabinets and extensions must have shutters for ventilation and a lock for locking. Be sure to have the inscription “Flammable. Gas". The installation must be carried out by a qualified gas worker. At the entrance to the courtyard there should be a sign “Flammable. Cylinders with gas.

The use of bottled gas requires a thorough approach to ensure safety and ease of use. We propose to consider the simplest example connecting a propane cylinder to a gas stove: a connection diagram, shut-off and control valves, organization of storage conditions.

Where to install the balloon

The main generalized requirement for the use of gas-cylinder equipment can be called ensuring the safety of people. For this reason, gas cylinders are not recommended for installation in habitable rooms and technical rooms associated with residential building directly or through ventilation.

A distinctive feature of propane gas is its high density. Bottled gas is heavier than air and can accumulate in the lower floors of buildings. Therefore, it is strictly not allowed to install cylinders in the underground or technical rooms below ground level. If in the usual case small leaks do not pose a danger due to constant air exchange, then in the lowlands the gas is capable of long time accumulate to explosive concentrations. It is possible to install gas cylinders in accordance with SNIP 42-01-2002 only inside buildings no higher than 2 floors, in the amount of no more than one and at a distance of 0.5 m from gas stoves and 1 m from heating appliances.

To make the installation safer and exclude unauthorized persons from accessing the gas equipment, the cylinders are placed either in a room with a separate entrance or in an outdoor metal cabinet. It is especially important when outdoor installation take account of temperature regime operation. Bottled gas consists of a mixture of propane and butane, each of which different temperature boiling. When the cylinder is cooled below 0 ° C, only propane will evaporate from the mixture, while the remaining butane in the cylinder cannot be rationally used. With more low temperatures it is possible to completely stop the flow of gas to the stove.

The main way to achieve normal operation at low temperatures is the use of so-called winter gas mixtures that can evaporate at temperatures down to -40 ° C. However, the problem is that such gas may be in short supply seasonally, and besides, the possibility of refueling a mixture of mediocre quality cannot be ruled out. There are two ways to resolve the issue with the guarantee: either insulate the attached metal cabinet, counting on the penetration of heat from the building, or additionally heat the cylinders using a self-regulating cable.

The height of the cabinet should be at least 20-30 cm higher than the height of the cylinders so that they are not installed on the floor, but with a gap, for example, on two metal rails or a high pallet. In this case, the cabinet must be protected from the penetration of melt, rain water and heating from sunlight above 40 ° C.

Which gearbox to choose

Gas stoves have built-in jets designed for a constant gas pressure, while the pressure in the cylinder decreases with consumption. To normalize combustion, the cylinder is connected to the stove not directly, but through a gearbox. Reducers for liquefied domestic gas are called propane and, as a rule, have a red or metallic body color.

The main characteristics of the reducer - outlet pressure and throughput - must be selected for the parameters of a single plate. If it is not possible to set the passport pressure value, you should purchase an adjustable type reducer and manually adjust it. Also, adjustable reducers are directly shown when using cylinders with a capacity of 20 liters or more, where the pressure drop is more pronounced.

For domestic use of propane, reverse gears are recommended. Due to the low pressure values ​​​​of liquefied gas and the low difference between the inlet and outlet, the use of multistage gearboxes is not economically justified. The only requirement is to use the reducers specified in their technical standard in conjunction with composite cylinders.

A separate nuance in the choice of the gearbox may be the temperature regime of operation of the cylinders. The fact is that during the evaporation of liquid gas, an intensive decrease in its temperature is observed. So, if initially the propane-butane mixture is at a temperature of -5 ... -10 ° C, in the gearbox itself its temperature can drop to the level of condensation, due to which the gas becomes liquid again, and the gearbox stops working. One way out of such a specific situation is to use gearboxes with a built-in heating system.

What hoses and tubes to use for connections

According to the rules safe operation gas equipment, it is not allowed to use oxygen and hydraulic hoses for laying gas pipelines. This is due to the high temperature difference between the transported gas and external environment, which leads to accelerated degradation of the hose material and the appearance of microscopic leaks. With the properties of liquefied gas to accumulate in rooms, such phenomena pose an increased danger.

To connect gas bottle There are three options for the stovetop. The first is to use special flexible rubber hoses for combustible hydrocarbons. In this case, they are connected to the gearbox through a standard fitting with a screw clamp. The same fitting is installed on the inlet pipe gas stove, the hose is also connected to it with a compression clamp. If it is necessary to connect two pieces of hose, it is not allowed to use double-sided fittings, instead of them, threaded connectors with double crimping of the shank with clamps should be used. Distinctive feature such connections for gas pipelines are conical threads and the absence of elastic seals.

Connecting the plate to the cylinder using flexible hoses has a number of limitations. The length of the hose must not exceed 150 cm, its gasket must remain visible to constantly monitor the condition of the sheath and avoid damage. Some of the restrictions can be partially circumvented by using metal bellows hoses. They form a semi-rigid frame, which can have an almost unlimited length, while maintaining resistance to temperature effects and mechanical damage.

At the same time, safety rules prohibit the passage of flexible and semi-flexible ducts through walls where their condition cannot be visually assessed. Link if necessary cooker with a cylinder installed outdoors, into the hole in the wall should be on cement mortar case from steel pipe. Inside the case is a steel tube of smaller diameter with threads at both ends, the space between the walls is filled with a plastic sealant, for example, mounting foam or silicone. The connection of bellows or flexible hoses must only be carried out through threaded adapters of the appropriate type.

Cranes and other fittings

A gas cock must be installed at the point where the gas pipeline is connected to the stove, blocking the gas supply in the event of a stove failure. It could be either ball valve with a yellow flywheel, or a plug gas valve. The disadvantage of the latter is the need for periodic maintenance.

Another useful addition to the gas pipeline can be a flow meter. Its inclusion in the transportation chain will help to respond in a timely manner to the exhaustion of the mixture in the cylinder and replace it. The metering device should not have the outstanding accuracy required to control gas consumption in main networks, a device worth up to 2 thousand rubles will be enough.

When connecting several cylinders at the same time, a connecting ramp can be used. Its installation helps to reduce the rate of gas evaporation from each cylinder and make the risk of freezing of the mixture in the reducer less likely. The installation of the ramp can be done independently with any material for the manufacture of the gas pipeline.

Refinement of the stove for bottled gas

Not every stove can initially run on liquefied gas. The main obstacle is the higher working pressure, due to which there is a lack of oxygen in the burners, which is expressed in yellow combustion and the appearance of soot.

You can correct the situation by replacing the jets for methane with nozzles for LPG. They have exactly the same form factor, but the hole diameter is slightly smaller. If you plan to connect a new stove, it should most likely come with a set of jets for liquefied gas. If replacement jets are not available, they can be purchased at a reasonable price.

The diameter of the holes in the jets for liquefied gas depends on the pressure in the outgoing chamber of the reducer and the power of the burner. Thus, diameters of 0.43-0.6 mm for a pressure of 50 mbar and 0.5-0.75 for a pressure of 30 mbar are considered standard values ​​​​for liquefied gas stoves. Individual slab manufacturers may set their own diameters and the use of nozzles with different orifice diameters may void the warranty.

Replacing jets can be done in two ways, depending on the design of the plate. In the simplest version, it is enough to remove the burner body and look inside the seat sleeve. If a jet is visible at the bottom - a hex head with a hole in the center - it is unscrewed socket wrench 7 or 8 mm and screw in the replacement nozzle. If a cone with a hole is visible inside, you will have to remove the top panel by unscrewing several bolts on the sides from different sides. The jet itself in this version of the design does not get out, it is pressed into the stuffing box seals. It is necessary to unclench the mustache of the compression coupling, move the nozzle down along with the inlet pipe, and then pull the jet from the landing fitting and install a new one.

Commissioning of the plant

The entire installation of the gas pipeline is carried out without connecting it to the cylinder. When the tubes or hoses are connected to the plate and interconnected, the reducer nut is screwed onto the cylinder valve and tightened. Then, if a flexible hose is used, it is put on the fitting and crimped with a clamp. If bellows tubes are selected, the nipple must be unscrewed from the gearbox housing and screwed into it with a threaded adapter of the appropriate size.

When the unit is assembled, you need to open the valve on the cylinder and, by turning the reducer regulator, set the required outlet pressure. When the gas has entered the pipe and hose system, each connection is thickly coated with soapy foam and checked for leaks. After the integrity of the gas pipeline is confirmed, you can open the stove tap and try to sequentially ignite the burners.

If each of them smokes or the flame burns in a color other than blue or greenish, it is necessary to reduce the pressure with a valve on the reducer. If the malfunction is typical only for some burners, then the jets for them are selected incorrectly. If the burner goes out in the minimum fire position, adjust the low flow screw on the stove tap or try to slightly increase the pressure with the reducer screw.

The gas reducer in the gas supply system performs an important stabilizing function. Due to it, variable and high pressure is smoothed out to more or less constant, which ensures the normal and safe operation of the equipment.

Reducer "Frog" for a gas cylinder

Gearboxes are used almost everywhere we are talking about gas equipment, whether it be devices operating on combustible (methane, hydrogen, etc.) or inert (nitrogen, helium, etc.) gases. A typical household example is the gas cylinder reducer, also known as the "frog".

It is familiar to almost all owners of individual (autonomous) sources, who are forced to purchase them due to their remoteness from highways and the lack of connection to a centralized gas supply for this reason. must remain at a pressure of about 15 bar, while for consumer devices it is normal from 10 to 36 mbar.

If you do not first pass propane through the reducer, then the results of a direct connection may come as a complete surprise to you. This is especially true for compressed gas cylinders (eg methane at a pressure of 250 bar). "Frog" is inexpensive, and it's easier to get it than to spend money on eliminating the consequences of the disaster.

Motorists who have equipped their cars with economical gas-balloon equipment are also familiar with this device. Liquefied (or compressed) gas in such systems is also first sent to the propane-butane mixture (or methane) reducer, and only then enters the carburetor or injector.

The gas reducer finds application also in the industry. At transition points from major highways to local networks a significant reduction in pressure is required. Powerful and dimensional products are used here. Another example is the gearboxes for gas tanks involved in the supply industrial facilities or human settlements.

Classification

Legalizes the requirements for products GOST 13861-89. It, in particular, establishes the classification of these devices, given in Table. one.

As can be seen from the table, each device is designed not only to work for a specific purpose, but also for a specific gas. And if propane is indicated as a reduced gas in the labeling and documentation of the product, then such a reducer gas propane only allowed to flow, and attempting to pass another gas (e.g. methane) through it may be unsafe for health.

To avoid misuse, already in itself appearance Devices are manufactured with additional precautions. For example, reducers for combustible gases (eg methane) have left-hand threaded fittings, while non-combustible gases (eg nitrogen gases) have right-hand threads. For differences, color highlighting is also used.

Attention should also be paid to throughput, which determines the gas flow provided by the device. Before choosing a specific model, you should make sure that this indicator is sufficient for the consuming equipment used.

Device and scheme of work

The basic arrangement of all gearboxes is similar. Dimensions may vary constituent parts, them design features etc. The scheme of operation is similar to that observed in the float chamber.

In the cavity of the housing, which has inlet and outlet pipes, between two washers there is a membrane balanced from above by a spring resting against the plane of the housing, and from below by a rocker arm pivotally connected to the inlet valve. At low pressure, the spring exerts enough force on the diaphragm to keep the inlet valve open, allowing the gas to flow through the device with little or no resistance.

Gas reducer diagram high pressure

When the pressure rises to a certain threshold value, the membrane begins to compress the spring, while simultaneously covering the inlet valve with a rocker. The pressure level required for these actions is mainly determined by the following parameters:

• membrane dimensions;
• spring characteristics;
• the force required to complete the work of closing the valve.

At the same time, the propane reducer can be equipped with a mechanism for adjusting the working pressure within certain limits, or manufactured without it (“frog” is an example of an unregulated option). Products designed to work as part of an automotive system are also configurable (methane usually has one regulator, propane has one or two).

The supra-membrane part of the body may have an opening at the top and thus be in communication with environment. There are also sealed models. They do not have a hole and a spring, and instead of the latter, the cavity is filled with gas, which provides balance with its pressure. Combinations are also available.

Here, the pressure of the methane going through the reducer (for example) is simultaneously regulated by the action of both the spring and the gas. The top hole in such gas trains performs the function feedback. It connects the product to the volume into which the gas is directed, thus establishing the dependence of the pressure in the reducer on the pressure in the volume (i.e., the supply is proportional).

Adjustment and repair

You can do it yourself with the help of available tools and a repair kit, but only if you know exactly what you are doing. Insufficiently qualified adjustment and assembly can lead to disastrous consequences. The main signs of abnormal operation of the product are as follows:

• deviation of the output pressure from the permissible limits;
• gas leak.

The pressure deviation is usually caused by a breakage or displacement of the spring, or the escape of the compensating gas that performs its function due to depressurization of a part of the housing. But if the spring malfunction is still to be eliminated with the help of a repair kit, then the gas version belongs to the category of non-repairable ones (the device is completely changed).

A gas leak can be caused by a broken diaphragm, a leak in the housing, or a malfunctioning float valve. If the latter begins to pass gas, this can also manifest itself in the consumer product (for example, in gas water heater). Since the pressure at the outlet of the reducer is approximately equal to the input, then in the absence of flow (the consuming device is temporarily turned off), leakage will be inevitable.

Such a malfunction is difficult to diagnose for the reason that turning on the consuming device normalizes the situation. It can be determined only by measuring the gas pressure at the outlet of the reducer in the absence of consumption (as a rule, it should not exceed the nominal value by more than 20%).

Most problems can be eliminated by adjusting (improving) the product or replacing some of its components with new ones taken from the repair kit.

But it is worth noting that the gearboxes are collapsible and non-collapsible (sealed) design. The latter are subject to replacement only in their entirety.

So, having stocked up with an appropriate repair kit, the product must first be disassembled. After visually inspecting the spring and membrane removed from the housing, it should be established which of them caused the malfunction. A broken spring must be replaced with a new one from the repair kit.

If the spring has not broken, but simply tightened up, having lost elasticity from time to time, you can not change it, but simply pick up and put a gasket of the required thickness from the body side without closing the existing hole with it.

If the membrane breaks, it should be replaced using a similar one from the repair kit, but, as a rule, it is not easy to make a tight connection with the washers surrounding it. Therefore, if you are unsure of your skill, think about the advisability of purchasing a new gearbox.

With the integrity of the spring and the membrane, you should pay attention to the bypass valve.

This is a tube with a small hole, from the end of which a rocker is pressed through a rubber gasket. There are several typical problems regarding valve operation:

• the normal course of the rocker is disturbed;
• worn or damaged rubber gasket;
• the end of the tube is deformed.

Valve adjustment is a simple process. The mobility of the rocker arm can be restored by turning or replacing its hinges. The damaged gasket should be cut off and glued in place of the same size from the repair kit. The roughness and evenness of the end of the tube, which ensures a snug fit of the gasket, is achieved by grinding it.

If the failure of the reducer is a gas leak due to leaks in the places where the membrane fits on the housing, then the broken integrity can be restored using silicone sealant. When making adjustments or repairs, and for any other reason not initially related to depressurization, it will not be superfluous to also apply sealant in these places, which will prevent a similar problem in the future.

Upon completion repair work it is necessary to immediately check the tightness of the product with a soap solution. If there are no bubbles that indicate leaks, the gearbox should be re-tested after one day, then after a few more days. Subsequently, periodic monitoring (eg monthly) is recommended.

Like any other gas-related equipment, the reducer will serve well if right choice models and the adoption of simple measures that contribute to safe operation. Periodic maintenance and timely detection of faults will save you from trouble.

The reducer for a household gas cylinder is an intermediate link in the gas source-gas consumer chain. It performs the function of stabilizing the working pressure of the propane-butane gas mixture, which is in the cylinder in a liquefied state, and therefore under high overpressure.

Reducers for household gas cylinders

The stabilization function involves maintaining the gas pressure in the range of operating values ​​for the safe operation of gas stoves. They can be classified according to the following features:

• along the gas mixture - direct, reverse;
• if possible, regulation - regulated, unregulated;
• according to the control range - input - 2-3 MPa, output - 0.3-1.5 MPa;
• according to the method of connection - fitting, nipple;
• throughput;
• according to the presence of indication - with a pressure gauge, without a pressure gauge.

Also, due to the design features, they have a variety of shapes, the material from which they are made, the mass, the color of the color.

How does a gas reducer work?

Direct drive gearbox

high pressure gas from the cylinder enters the chamber, equipped with a shut-off valve. valve under pressure overpressure opens and begins to rest against the saddle. After that, the gas stops flowing to the outlet.

The diaphragm responsible for pressure regulation, under the action of the spring, begins to displace the valve from the seat surface. The pressure is reduced due to a small passage and reaches a safe, serviceable.

Further, the straightened spring allows the valve to open access to the flow of a new volume of gas from the cylinder, and the regulation process is repeated. On non-adjustable gearboxes, the spring force is set at the factory, acting as a pressure regulator.

Reverse gear

Here the principle is somewhat different. Incoming gas from the source presses the valve against the seat, preventing it from escaping. The design contains a screw, with the help of which the spring compression force is adjusted.

By compressing the spring with a screw (regulator), the safety diaphragm is bent, passing a certain amount of gas. The support disc actuates the return spring, after which the valve rises, freeing the way for the fuel.

The working chamber has the same pressure as in the cylinder. The membrane under the action of the spring returns to its original state, and the support disk moves downward, while pressing on the return spring. As a result, the valve is pressed against the body seat.

It is worth saying that many note the great popularity of reverse action gearboxes. They are safer to use.

How and why gearboxes are used

The gas ones look no different from each other. It is customary to manufacture them, depending on the type of gas. All gases used are divided into two groups:

• combustible;
• non-combustible.

Storage cylinders are fitted with a right hand (normal) thread for non-flammable gases. Accordingly, cylinders with combustible gases are equipped with a left-hand thread. The same principles apply to gearboxes.

Many gardeners have noticed that if you need to replace an empty container to power the stove, the nut is unscrewed in the opposite direction.

Gas reducers are found in almost all spheres of our life. From industry to medicine. For welding work used: oxygen, acetylene, argon, carbon dioxide and others.

Builders other than welding equipment when installing a roof, use propane. All household cylinders are also equipped with propane reducers.

Medical institutions, in addition to oxygen, use nitrogen and the recently popular “laughing gas”.

We are used to seeing that gas storage tanks are made of metal. They are of considerable size and weight. But they are being replaced by containers made of composite materials.

Unlike metal cylinders, they are safer and lighter. Manufacturers claim that in case of an emergency, it does not scatter to the sides, forming a large number of traumatic fragments.

Accordingly for composite cylinders a dedicated gearbox is required. Among their characteristics it is worth noting:

• the nut is screwed on with ease;
• for the gasket, a service life of 10 years is declared;
• the design ensures complete sealing.

At the moment, reducers for household gas equipment have entered our lives so tightly that we treat them with some disdain. And they are responsible for the integrity of the living space and you can buy them at a low price.

Before buying, you should pay attention to the following:

• type of gas used;
• type of gas cylinder;
• connecting dimensions;
• is there a regulator to change the pressure;
• price.

For safety reasons, a gas reducer designed for one type of gas cannot be used with another type of gas. For household cylinders the gearbox must be selected according to the inscription on it. Cylinders filled with propane or methane. And their density and flammability are completely different.

Reducers for gas bottles

Hardly even one modern man can imagine his life without a stove. But there are situations when gasification of the house is impractical or impossible. The reasons are different, but the result is the same: people have to use liquefied propane in cylinders. At independent equipment point, many questions can arise, from choosing a location for the device to connecting to a power source. Mistakes and mistakes made during the installation and connection of the gas stove to the cylinder can lead to irreversible tragic consequences.

Important! Gas equipment that will be used for cooking must be in good condition.

Materials and tools necessary for work

When connecting a gas cylinder to the stove, you will need:

• 2 clamps;
• fitting having a spout to connect the hose and internal thread(should be included with the gas appliance);
• the stove is new or old, but in good condition;
• reducer with inlet pressure 30 mbar;
• gas cylinder made of metal-composite, polymer-composite or other special materials with a capacity of 5–50 l;
• rubber or rubber-polymer connecting hose, which can support room temperature and does not heat up above 30 degrees;
• sealing tape;
• special gas key.

Important! To connect the gas model of the stove, you must use only keys with a brass or copper coating, which, upon impact, will not knock out a spark.

Jets for bottled gas

One must take into account important point: slabs originally designed to work on the main natural gas, have jets (nozzles) that are not suitable for operation on bottled propane.

The jet is similar to a bolt with a hole in the upper part through which fuel enters the burner. Bottled gas nozzles have a smaller orifice because LPG pressure is higher than that of natural fuels. Therefore, to connect such a plate to a cylinder with liquefied gas you will need to purchase and replace the entire set of jets.

• . It is purchased at specialized points of sale, it must be designed specifically for gas. Its length must exceed the distance between the connected equipment by 150 cm, since it must not be used in a taut state.

Important! Do not use old hoses, as their integrity inner surface may be broken.

Choosing a place to install the cylinder

Before connecting the gas stove to the cylinder, you need to choose the place where the devices will be installed, since the distance between them must be at least 100 cm. The safety instructions prescribe in a room with a connected gas equipment have a window.

When using a shielded cylinder, the distance between it and the stove can be reduced to 50 cm.

• If the gas container is located in the same room with kitchen appliance, it is advisable to place it in a metal cabinet or make a wooden mount.
• The cylinder can be in the pantry, located behind the wall of the kitchen. In this case, you will need to make a hole for the hose.
• The best option in terms of security is to install the cylinder in a special metal box located on the street and locked with a padlock.

Important! You can place a balloon in an apartment only if the building has no more than 2 floors.

Sequencing

After finishing installation work you need to make sure the tightness of the connections and the safe functioning of the elements. The simplest way is to apply a high foam soap solution to the joints before supplying the propane from the tank to the stove. Problems with gas leakage in places of poor-quality fastening will manifest themselves as the appearance of soap bubbles.
