To correctly reconfigure the stove to use bottled gas, it is only necessary to replace the jets for 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 stove to a gas cylinder
Jets - important detail any plate. 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, which enters our houses and apartments through the central highways, is much lower than the pressure of bottled gas. Therefore, the size of the holes in the jets 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, then you can purchase them separately and replace them yourself.
List of required tools
Before proceeding with the conversion of the stove to the use of liquefied gas and connecting it to gas cylinder, it is worthwhile to prepare in advance all the tools and spare parts necessary for this. First of all, you will need:
- new jets;
- flexible hose for a gas cylinder with a length of more than one and a half meters. It must be new without any cracks and damage, since the safety of others depends on it;
- gas reducer with outlet pressure 30 mBar (frog);
- wrenches (wrench 7 mm, open-end);
- screwdrivers;
- sealant;
- soapy water.
How to choose the right jets
Jets for gas stove 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 enters. As a rule, for convenience of choice, manufacturers mark their products by knocking out the diameter of the outlet at the end of the jet.
When buying such a device, you should not save money, and even more so try to change the diameter of its hole yourself. This can lead to disastrous consequences. In the instructions for the stove, you need to look at the specific diameter of the jet hole for each burner. It is not permissible to use jets with a hole diameter larger than recommended. This will not allow you to properly regulate the flame, it will be more than acceptable. When using nozzles with a smaller diameter, the flame will be insufficient.
Replacing jets and connecting a gas cylinder
All work on reconfiguring 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 and the top cover of the stove, unscrew with wrench old jets and, observing the required dimensions for each of the burners, screw in new jets. Then put everything back together in reverse order. To replace the jets in the oven, it is necessary to dismantle the surfaces hiding the burner of the oven and grill according to the instructions for the stove, then replace the jets and assemble the oven.
After that, you can connect the gas cylinder to the stove. To do this, we wind the fitting onto the inlet pipe of the 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 fix 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 stations.
Secrets of a secure connection
The installation of any gas equipment is somehow 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 located at a distance of at least 1.5 meters from the gas stove. A special metal box located on the street is ideal for this;
- hose, reducer, all gas equipment connections must be constantly accessible for visual control;
- if you smell gas, you must immediately ventilate the room and do not use electrical appliances.
Checking the operation of the hob
First, it is important to check the tightness of all connections. This will require a common soap solution, which is applied to the joints to check their reliability and the absence of gas leakage. If a leak is detected, it is recommended to tighten the hose clamps and replace the gaskets on the gearbox and re-check.
Now you can check the operation of the stove itself. If the burners light up easily, and the flame has a bluish tint without the so-called yellow tongues, burns with good power and evenly, then we can say with confidence that everything is done correctly.
Currently natural gas is the most optimal fuel for heating the house. The only negative is that it is not always possible to connect the heating system to the main gas pipeline. In this case, you can pay attention to an alternative in the form of liquefied gas - boilers using bottled gas in our country are not uncommon.
Classification
Boilers running on liquefied gas, are single-circuit and double-circuit. A single-circuit boiler is intended only for heating, while a double-circuit boiler is capable of both heating the house and providing hot water in it.
Consumers are offered wall, floor gas boilers with open and closed combustion chambers. In addition, attention should be paid to the power of this heater. A variety of modifications often makes it difficult for the user to choose, so it is worth dwelling in more detail on the most important characteristics.
For boilers operating on liquefied gas, the ability to operate at low pressure is of fundamental importance.
The constant supply of bottled gas will be carried out at a pressure of 3-4 Mbar. Therefore, when choosing a boiler, you should pay attention to this parameter.
efficiency
Efficiency is one of the most important parameters heating system. Liquefied gas is more expensive than trunk gas, and transportation costs must be added to its cost.
The efficiency of modern serviceable equipment can reach 90-95%. To calculate the gas consumption for heating, you need to know the total area of \u200b\u200bthe room: approximately 1 kW of power is consumed per 10 sq.m.
For heating and hot water country house 100 square meters will require about 2 cylinders per week and 8-9 cylinders per month. You can connect the cylinders in a group: according to the rules, the use of a system of cylinders up to 15 pcs is allowed. In this case, gas containers must be in a closed metal cabinet.
Mounting hardware
To install the heating system you will need:
- a gas boiler;
- burner for liquefied (balloon) gas and gas cylinders themselves;
- valves and reducers.
Bottled gas burners differ in their configuration from conventional ones, and are usually included as standard with gas boilers. If necessary, they can be purchased separately. Shut-off valves and the necessary gearboxes can be purchased from the company or directly at cylinder filling stations.
Connection
A cylinder or a group of cylinders is connected to the boiler through a reducer with a throughput of about 2 m3 / hour. Reducers for domestic stoves are designed for lower throughput - they are not suitable for the heating system. The gas tank system can have one common gear or a separate regulator for each cylinder. The second option is more expensive, but it is recommended by the masters - separate gearboxes provide maximum safety.
Cylinders of liquefied gas cannot be installed outdoors: the cold will provoke a decrease in pressure, and the heating pad may refuse to work. The perfect place for installation is a warm, ventilated room. It is important to remember that bottled gas is heavier than air, and in the event of a leak, it will accumulate at the bottom, increasing the likelihood of an explosion. Therefore, the room should be chosen separately from living rooms. It should not have basements and subfloors!
Gas cylinders are connected to the boiler burner using a metal corrugated pipe- this reduces the likelihood of gas leaks due to system vibrations.
With automatic sensors and correct settings it is possible to reduce propane consumption rates by 3-4 times. If a we are talking about country house, then the gas consumption will be even lower: for the period of absence of people, the automation will maintain the temperature at the level of 6-9 ° C, which will reduce the propane consumption to 0.7-0.8 cylinders per week. Heating a building with liquefied gas is not the best cheap option, but in some cases it is the most optimal if there is no problem in the delivery of cylinders.
The gas boiler perfectly performs its functions when connected to the main gas pipeline. In this case, it is quite easy to switch the equipment to a constant source of fuel supply - just change the burner.
But if there are no prospects for connecting the building to the gas pipeline, the feasibility of installing gas boiler. For home with total area more than 100 m2 and maintaining a temperature of about 25 ° C, it is worth considering installing solid fuel boiler or another generator of heat and water heating.
Refueling
Cylinders undergo mandatory certification every 3 years - this is necessary for the user's own safety. Such containers can serve for about 10 years. standard house consumes about 10-12 cylinders per month, so they will have to be refueled weekly - it is impossible to transport more than 3 cylinders at a time without special permission.
Before refueling, the vessels must be prepared. To do this, you need to remove the condensate, which artificially reduces the usable volume and harms the steel walls. Removing condensate is the prerogative of specialists; doing such work with your own hands is always a risk. If for some reason it is difficult to find a master, then you will have to carry out the procedure yourself. The cylinder is taken out to an open space without sources of fire, grounded and then the gearbox is removed. Leave for 2 hours so that the remaining gas disappears. After two hours of inactivity, the vessel turns over, and the water flows into the ground. You can take it to a gas station.
It is worth choosing a refueller who organizes both transportation and a guarantee for work. It is better not to go to car stations, because their equipment does not have a special cut-off valve that regulates gas filling household cylinders. They also do not have a special connector for connecting the cylinder to the station equipment.
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 connected to the residential building directly or through ventilation.
The hallmark 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 consider temperature regime operation. Bottled gas is a mixture of propane and butane, each with 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 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, it is considered to use the 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. You can solve the issue with a guarantee in two ways: 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 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 color corps.
The main characteristics of the reducer are the outlet pressure and throughput- must be selected according to 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.
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, they are connected to the gearbox through a standard fitting with a screw clamp. The same fitting is installed on the inlet pipe of the gas stove, the hose is also connected to it with a 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 higher operating 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.
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. With self-equipping a 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 that can maintain 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
- . 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 the integrity of their inner surface may be compromised.
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.
