How to properly connect a gas burner to a cylinder. Gas burner. The main tool for built-up waterproofing. Difference in slabs

Hardly even one modern man will be able to imagine his life without a stove. But there are situations when gasification of a home 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 points, many questions may arise, from choosing a location for the device to connecting to an energy source. Mistakes and mistakes made during installation and connection 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 required for work

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

2 clamps;
a fitting having a spout for attaching a hose and internal thread(must 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 liters;
rubber or rubber-polymer connecting hose that can support room temperature and does not heat above 30 degrees;
sealing tape;
special gas key.

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

Jets for bottled gas

. Purchased at specialized sales points, it must be intended specifically for gas. Its length must exceed the distance between the connected equipment by 150 cm, since it is prohibited to use it in a tense state.

Important! Do not use old hoses, as the integrity of their internal surface may be damaged.

Choosing a place to install the cylinder

Before connecting the gas stove to the cylinder, you need to select the place where the devices will be installed, since the distance between them must be at least 100 cm. Safety instructions require that there be a window in the room with connected gas equipment.

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

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

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

To correctly reconfigure the stove to use bottled gas, you only need to replace the nozzles supplying the gas mixture to the burners.

We will tell you how to do it correctly and safely with your own hands, without resorting to outside help.

Features of connecting a kitchen stove to a gas cylinder

Jets - important detail any slab. Each jet has a special hole of a specific diameter through which the gas mixture is supplied to the burner. As is known, pressure natural gas, which enters our houses and apartments through central highways, is much lower than the pressure of bottled gas. Therefore, the size of the holes in the nozzles of gas stoves operating on bottled gas should be smaller than in conventional stoves. Some manufacturers of gas stoves pre-equip them with jets for different types gas mixtures(propane-butane, natural gas, etc.). However, if your stove does not have such jets, you can purchase them separately and replace them yourself.

List of required tools

Before you start changing the stove to use liquefied gas and connecting it to a gas cylinder, it is worth preparing in advance all the necessary tools and spare parts for this. First of all, you will need:

new jets;
flexible hose for a gas cylinder more than one and a half meters long. It must be new without any cracks or damage, since the safety of others depends on this;
gas reducer with outlet pressure 30 mBar (frog);
wrenches (7 mm wrench, open-end);
seal;
soapy water.

How to choose the right jets

Jets for a gas stove are sold in any specialized store. Outwardly, they resemble ordinary threaded bolts. In the center they have a special hole of a specific diameter through which gas flows. As a rule, for ease of selection, manufacturers mark their products by knocking out the diameter of the outlet hole at the end of the nozzle.

When purchasing such a device, you should not save money, much less try to change the diameter of its hole yourself. This can cause disastrous consequences. In the instructions for the stove, you need to look at the specific diameter of the nozzle hole for each burner. It is not permissible to use jets with a hole diameter larger than the recommended one. This will not allow you to regulate the flame normally; it will be larger than permissible. When using jets with a smaller diameter, the flame will be insufficient.

Replacing jets and connecting a gas cylinder

All work to reconfigure the stove to use bottled gas must be carried out in compliance with basic safety rules. Replacement work must be carried out before connecting the stove to gas. It is necessary to remove the burners, and on some stoves the top cover of the stove, unscrew it using wrench old jets and, observing the required dimensions for each of the burners, screw in new jets. Then collect everything in the reverse order of parsing. To replace the jets in the oven, you must dismantle the surfaces that hide the oven and grill burner according to the instructions for the stove, then replace the jets and reassemble the oven.

After this, you can connect the gas cylinder to the stove. To do this, we screw a fitting onto the inlet pipe of the kitchen stove, put a hose on it and tighten it with a worm clamp. We connect the other end of the hose to the gearbox and secure it with a clamp. We connect the reducer to the cylinder using an open-end wrench. The gearbox must be in a strictly horizontal position. To seal all threaded connections, it is necessary to use special paronite gaskets. They can be purchased both in specialized stores and at gas filling stations.

Secrets of a secure connection

Installation of any gas equipment one way or another associated with a certain risk to the health and life of others. Therefore, it is important to strictly adhere to certain rules during installation work:

The gas stove must not be installed in rooms with poor ventilation;
The gas cylinder must be placed at a distance of at least 1.5 meters from the gas stove. A special metal box located outside is ideal for this;
the hose, reducer, all connections of gas equipment must be constantly accessible for visual inspection;
If you detect the smell of gas, you must immediately ventilate the room and do not use electrical appliances.

Checking the operation of the stove

First, it is important to check the tightness of all connections. To do this, you will need a regular soap solution, which is applied to the connections to check their reliability and the absence of gas leaks. If a leak is detected, it is recommended to tighten the clamps on the hose and replace the gaskets on the gearbox and recheck.

Now you can check the operation of the stove itself. If the burners light up easily, and the flame has a bluish tint without so-called yellow tongues, burns with good intensity and evenly, then we can confidently say that everything was done correctly.

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

Where to install the cylinder

The main general requirement for the use of gas 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 connected to a 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 forbidden to install cylinders in underground or technical rooms below ground level. If in the normal case small leaks do not pose a danger due to constant air exchange, then in the lowlands the gas can accumulate for a long time to explosive concentrations. Gas cylinders in accordance with SNIP 42-01-2002 can only be installed inside buildings no higher than 2 floors, in quantities 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 prevent access to gas equipment by unauthorized persons, the cylinders are placed either in a room with a separate entrance or in an outdoor metal cabinet. Particularly important when outdoor installation consider temperature regime operation. Bottled gas is a mixture of propane and butane, each of which has a different boiling point. When the cylinder is cooled below 0 °C, only propane will evaporate from the mixture, while the remaining butane in the cylinder cannot be efficiently 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 seasonal shortage, and the possibility of filling with a mixture of mediocre quality cannot be ruled out. The warranty issue can be resolved in two ways: either insulate the attached metal cabinet, relying on heat penetration 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 greater than the height of the cylinders, so that they are not installed on the floor, but with a gap, for example, on two metal slats or a high pallet. In this case, the cabinet must be protected from the penetration of melt and rain water and heating from sun rays over 40 °C.

Which gearbox to choose?

Gas stoves have built-in jets designed for 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 reducer. Reducers for liquefied household gas are called propane and, as a rule, have a red or metallic color housings.

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

Reducers are recommended for the use of propane for domestic purposes. reverse principle actions. Due to the low pressure values of liquefied gas and the low difference at the inlet and outlet, the use of multi-stage gearboxes is economically unjustified. The only requirement is to use reducers provided for by their technical standard in conjunction with composite cylinders.

A separate nuance in choosing a reducer may be the temperature regime of the cylinders’ operation. The fact is that when liquid gas evaporates, an intense decrease in its temperature is observed. So, if initially the propane-butane mixture is at a temperature of -5...-10 °C, in the reducer itself its temperature can drop to the condensation mark, due to which the gas becomes liquid again and the reducer stops working. One way out of this 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, oxygen and hydraulic hoses are not allowed to be used 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. Given the properties of liquefied gas to accumulate in rooms, such phenomena pose an increased danger.

There are three options for connecting a gas cylinder to a stove. The first is to use special flexible rubber hoses for flammable hydrocarbons. In this case, their connection to the gearbox is made through a standard fitting reinforced with a screw clamp. The same fitting is installed on the inlet pipe of the gas stove, the hose is connected to it also with a clamp. If it is necessary to connect two sections of hose, the use of double-sided fittings is not allowed; instead, threaded connectors with double crimping of the shank with clamps should be used. Distinctive feature Such connections for gas pipelines are tapered threads and lack elastic seals.

Connecting the plate to the cylinder using flexible hoses has a number of limitations. The length of the hose should not exceed 150 cm, its gasket must remain visible to constantly monitor the condition of the sheath and avoid damage. Some of the prohibitions can be partially circumvented by using metal bellows hoses. They form a semi-rigid structure, which can have an almost unlimited extent, while maintaining resistance to temperature influences 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 assessed visually. If it is necessary to connect a kitchen stove with a cylinder installed outdoors, the hole in the wall should be at cement mortar a case made of steel pipe. Inside the case there 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, polyurethane foam or silicone. Connection of bellows or flexible hoses must only be made through threaded adapters of the appropriate type.

Cranes and other fittings

At the point where the gas pipeline is connected to the stove, a gas tap, blocking the gas supply in the event of a malfunction of the stove. It could be either ball valve with a yellow flywheel, or a gas plug valve. The disadvantage of the latter is the need for periodic maintenance.

Another useful addition to a gas pipeline can be a flow meter. Its inclusion in the transportation chain will help to respond in a timely manner to the depletion of the mixture in the cylinder and replace it. The metering device does not have to have the outstanding accuracy necessary to monitor gas consumption in main networks; a device costing up to 2 thousand rubles will be sufficient.

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

Modification of the slab for bottled gas

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

The situation can be corrected by replacing the methane nozzles 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 will most likely come with a set of liquefied gas nozzles. If there are no replacement jets, they can be purchased at a reasonable price.

The diameter of the holes in the liquefied gas nozzles depends on the pressure in the outgoing chamber of the reducer and the power of the burner. So, standard values for liquefied gas stoves, diameters are considered to be 0.43-0.6 mm for a pressure of 50 mbar and 0.5-0.75 for a pressure of 30 mbar. Individual slab manufacturers may install eigenvalues diameters, and the use of nozzles with different hole 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 hexagonal head with a hole in the center - unscrew it socket wrench by 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 nozzle itself in this version of the design cannot be unscrewed; it is pressed onto the stuffing box seals. You need to unclench the whiskers of the crimp coupling, move the nozzle down along with the supply tube, and then pull the nozzle out of the 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 stove 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 fitting must be unscrewed from the gearbox housing and a threaded adapter of the appropriate size must be screwed into it.

When the installation is assembled, you need to open the valve on the cylinder and, by rotating the gear regulator, set the required outlet pressure. When the gas has entered the system of pipes and hoses, each connection is thickly coated with a foam-soap solution and checked for leaks. Once the integrity of the gas pipeline has been confirmed, you can open the stove tap and try to ignite the burners sequentially.

If each of them smokes or the flame burns in a color other than blue or greenish, it is necessary to reduce the pressure using the valve on the reducer. If the malfunction is typical only for some burners, it means that 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.

To correctly reconfigure the stove to use bottled gas, you only need to replace the nozzles supplying the gas mixture to the burners. We will tell you how to do it correctly and safely with your own hands, without resorting to outside help.
