Absence gas pipe in a private house turned into a headache for Russian residents. Many settlements still not gasified. And supplying a pipe to the site where a residential building is located costs from 150 to 300 thousand rubles. Not everyone can afford such an amount. Installing a gas cylinder will help solve the problem. Despite the fact that refilling and replacing it requires attention and caution, this task is accessible to everyone.

Gas cylinder for the dacha: advantages and disadvantages

When a person enters a private house who is not connected to the gas pipeline, he is faced with a choice: to use an electric stove, or whether it is possible to connect gas stove to the cylinder? Both solutions have both advantages and disadvantages. The benefits are as follows:

1. Gas-burner heats up much faster. Cooking time is shorter, which means more free time.
2. The cost of refueling is lower than the price of electricity. The exception is the use of electricity at a reduced rate. For example, for village residents. There is also a discount on payment utilities to the poor population.
3. In some regions, the rate of electricity consumption per person is limited to 50 kW per month. Once the limit is reached, the price increases significantly.

The disadvantages include:

1. Fare. Gas stations are less common than gasoline ones.
2. Inability to accurately determine how much fuel was filled into the cylinder.
3. Installing a gas stove in a room not equipped with ventilation is prohibited.

Where to place

First you need to decide where to install the tank. If you connect a gas cylinder to the stove in the country, you can place it in the kitchen not far from the stove. However, in the house for permanent residence It is better to place it in a separate room or outside in a metal cabinet. It's more secure.

If gas is stored at temperatures below 0 °C, then the propane-butane mixture must be winter-grade, otherwise it will not be completely consumed. Another advantage of installing cylinders on the street will be the absence of gas in residential premises (in case of a possible leak).

They are also not allowed to be installed in an unventilated area or below ground level (for example, in a basement or cellar). Propane is heavier than air, so it will pool if there is a leak. At a ratio to air of 2.3 to 9.5%, propane forms an explosive mixture. Distance from gas cylinder to kitchen stove should not be less than 1 m. And also not less than 1 meter to heating devices.

Installation diagram

To connect a permanent structure and country house applies different scheme. cylinder to the stove in a residential building? In this case, it is more rational to have a supply of several cylinders stored in a steel cabinet. It installs on concrete foundation with a base 0.25 m above ground level. The distance from the cabinet to the wall of the building should be 0.45 m, from the slab to the pipe passing through the wall - at least 0.2 m.

Cabinets with cylinders must not be placed on the side of the building façade, or on the side of transport passages.

Gas supply for summer kitchen

To connect a gas cylinder to a stove in the country, use the following diagram:

All detachable connections must be within reach to monitor their condition and check for leaks. Spare cylinders are prohibited from being kept in a residential area, even for a short period of time. According to safety regulations, they cannot block escape routes.

What are there

There are several options for gas delivery standard sizes containers. For frequent use, it is better to choose a tank big size. Whereas a gas cylinder for the dacha can be taken in a smaller size. It is more convenient to transport and easier to find a place in limited space. The cylinders have the following characteristics:

Please note that the volume of propane poured is less than the volume of the container itself. This is due to the safety of the gas cylinder. Tucked in winter time gas expands significantly in a warm room and can rupture the cylinder if filled in excess.

Rules of circulation

To protect yourself from the consequences associated with damage to the cylinder, you need to understand the operating rules:

1. Conduct scheduled certification. It consists of conducting a leak test under pressure and maintenance valve After that, a stamp is stamped on the upper skirt of the gas cylinder indicating the date of inspection and the expiration date of the certification. In addition, gas stations refuse to fill containers that have not passed inspection.
2. Private individuals are prohibited from transporting more than 5 cylinders at a time.
3. If defects in the housing or leakage through the valve are detected, the container must be sent for repair and maintenance.
4. Avoid overheating in direct sunlight.
5. During transportation, the valve must be closed with a protective cap.
6. Do not completely bleed gas from the tank. Sometimes this can lead to air being sucked in and forming an explosive mixture.

The operating gas pressure is 1.6 MPa. During periodic testing of the container, the pressure is raised to 3 MPa. For safe work the proportion of propane in the propane-butane mixture must be at least 60%

Difference in slabs

Kitchen stoves sold in stores use natural gas - methane - for combustion. The nozzle, which is located inside the burner, is designed to operate on this type of fuel. If such a stove is correctly connected to a gas cylinder, as many try to do, it will not work effectively. The flame will not create desired temperature and will smoke. This happens because the propane-butane mixture is in a liquefied state, while methane is in a gaseous state under pressure. More liquefied gas flows per unit of time, so the jets must be smaller. Therefore, before connecting the gas cylinder to the stove, the nozzles should be replaced. They come complete with the stove.

To change them, you need to remove the top surface of the kitchen appliance. To do this, remove the burners. Then release the side clamps and remove the top cover of the stove.

Changing the nozzle in the oven is also not difficult. To do this, you need to remove the back wall of the oven, after which access to the inside of the oven will open. The nozzle is connected to a gas supply tube, which is fixed with a metal bracket on the body. There is a rubber gasket between the tube and the nozzle, which must be installed when replacing the nozzle. It is very small and may not be noticed. It must be removed carefully so as not to damage it.

How long will one bottle last?

The 50 liter capacity is enough for several months of regular use. Cooking for a family of 3-4 people will use up gas within 3 months. If you regularly close the gas valve, the cylinder will last for more than long term. It is difficult to determine how much gas was added during refueling. Even a pressure gauge connected to the cylinder will only show pressure. You can accurately determine the amount by weighing the container before and after refilling. Knowing the density liquefied gas, you can understand how much was filled. To avoid deception associated with underfilling, you need to refuel at proven gas stations that have meters.

Camping gas stoves

Fans of long-distance travel often take with them travel stoves, on which they can quickly cook or heat up food. These are miniature devices weighing no more than 2.5 kg, easily fitting into a backpack or bag. The power of the burners of these devices is comparable to the power of the burners of household stoves - about 2.5 kW.

Their difference lies not only in their low weight, but also in the fact that they use gas in aerosol cans, which weigh from 200 to 500 g. Tourist stoves are equipped with wind protection for the burner. Expensive models have closed ceramic burners, which protect people from burns and protect the fire from bad weather.

How to connect a camping gas stove to a cylinder? The portable device has an adapter with a lock. You need to carefully insert the nozzle of the can into this adapter, lightly press on it and, aligning the grooves, turn it. When you press, you will hear a slight hissing sound, indicating that the valve has opened and gas is entering the device. After fixing the canister, you need to listen carefully. If the hissing does not stop, it means there is some kind of imbalance in the installation. You need to disconnect and do the operation again.

How to connect large format gas cylinders to a portable stove? To do this, some devices include a propane hose and a miniature reducer. The 5-liter cylinder does not take up much space and can be taken with you on a car trip.

Two in one

In order to reduce the number of calls to gas stations and reduce transportation costs for gas delivery, you can connect several cylinders into a single system. Such a connection is called a ramp. How to connect two gas cylinders to a stove? To do this, you need to add several devices to the connection diagram:

In this way, you can connect as many cylinders as you like. Such schemes are also used for heating houses.

How to connect a cylinder to a stove with your own hands

For self-connection you need to choose the right gas fittings:

1. Hoses. They must be designed for a propane mixture and can withstand operating pressure. They need to be checked for cracks. If the cylinder is installed outdoors, then it is more advisable to install a pipe from the gas source into the room.
2. Gas reducer for propane for domestic use. It differs from the industrial one in its narrow range of pressure adjustment, the absence of a pressure gauge and its low price. His throughput- 1.2 cu. m/hour. On one side it has a nut for connecting to the cylinder, on the other there is a fitting for the hose.
3. Clamps for fixing hoses to the fitting.

In addition, you will need a gas wrench and a screwdriver to tighten the clamps. When changing cylinders, it is imperative to monitor the condition of the gasket under the gearbox nut. Its malfunction will lead to excessive fuel consumption. You can use the top of a plastic bottle cap as a gasket by making a hole in the center and cutting it to required diameter.

How to avoid accidents

Usage gas equipment refers to dangerous species activities. To prevent trouble, you must follow several rules:

1. Do not leave the burners on long time unattended, especially at night.
2. Do not place cookware on burners without grates.
3. You cannot bring fully filled cylinders from a cold place into a warm room. Expanded gas can rupture the container.
4. Do not illuminate the meter with a lit match when checking.
5. Do not tie ropes to clothes drying pipes.
6. Do not allow young children to turn the stove on and off.

After connecting the gas cylinder to the stove, you need to check the system for leaks. Connections may leak gas. To ensure serviceability, you need to treat the connections of the hoses with the valve, reducer, or stove fitting with a soapy solution. If bubbles appear, the leak must be repaired.

The connection between the cylinder and the reducer must be checked after each refueling. Over time, non-volatile residues accumulate inside the container, and the useful volume of the reservoir decreases. Therefore, the condensate must be drained periodically. Fittings and nuts must be brass or bronze. Unlike steel ones, they do not produce a spark if accidentally struck.

The coupling nut on the propane reducer has a left-hand thread. This must be taken into account and unscrew it clockwise. Otherwise, the thread may be stripped.

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 normal cases small leaks do not pose a danger due to constant air exchange, then in the lowlands gas can for a long time accumulate until 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 consists of a mixture of propane and butane, each of which different temperatures 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 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, it is considered to use 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. There are two ways to resolve the warranty issue: 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 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. Gearboxes for liquefied domestic gas They are called propane and, as a rule, have a red or metallic body color.

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.

For the use of propane for domestic purposes, gearboxes of the reverse operating principle are recommended. 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 the 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. This can be either a ball valve with a yellow handwheel 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 the higher operating 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 nozzle is visible at the bottom - a hexagonal head with a hole in the center - unscrew it with a 7 or 8 mm socket wrench and screw in the nozzle to replace it. If a cone with a hole is visible inside, you will have to remove top panel by unscrewing several bolts on the sides from different sides. The nozzle itself in this design option 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 used flexible hose, 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 reducer 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.

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 you know, the pressure of natural gas that enters our houses and apartments is central highways, 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 reconfiguring the stove to use liquefied gas and connecting it to a gas cylinder, you should prepare in advance all the necessary tools and spare parts. 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);
• screwdrivers;
• 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 elementary rules security. 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 reverse order. 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, and 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 everyone 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

The installation of any gas equipment is in 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.
