How to determine the correct operation of a gas stove
When igniting the burner, there should be no extraneous sounds in the form of pops. The flame should burn evenly, its tongues should be bluish-white, it is not for nothing that gas is otherwise called "blue fuel".
If, during the combustion of an air-gas mixture, yellowish impurities are observed, and the tongues of flame acquire a red tint, then this clearly indicates that the jets are not working properly.
Yellow and red flames indicate malfunctioning injectors.
When converting a stove from main gas to cylinder gas, all the disadvantages described above are very characteristic. And plus to this, due to the wrong pressure, soot will be released. So it is difficult to notice it immediately with the naked eye, however, it will manifest itself in the form of black spots on the dishes after 1-2 days of operation.
Avoiding all these troubles is pretty easy. It is necessary to choose the right nozzles for the gas stove when changing operating conditions and converting to cylinder gas. It should be borne in mind that due to the difference in pressure of the incoming fuel, the diameter of the holes in the nozzles (jets) will also be different.
What is a jet (nozzle)
Almost all gas stoves equipped in such a way that they are capable of operating on both natural gas and propane (from a replaceable cylinder). It should be borne in mind that when switching to liquefied gas, not only the replacement of the nozzles is required, but also the installation of a reducer, which is responsible for equalizing the pressure of the incoming fuel.
The reducer stabilizes the pressure of the cylinder gas, ensuring the normal operation of the stove. It automatically maintains the pressure parameters necessary for the operation of the equipment and prevents the reverse flow of the medium
The nozzle (jet) is a bolt, in the head of which there is a hole for supplying gas to the burner. After entering the burner, the gas is mixed with air, and the gas-air mixture is ignited.
The nozzle ensures that gas is supplied to the burner in the required volume and at the appropriate pressure. Its size determines the volume of gas required for a normal combustion process.
Depending on the fuel used, there are two types of injectors: for supplying blue fuel from the main pipeline and for supplying gas from a gas holder or cylinder.
Jets (nozzles) for natural gas in comparison with jets for liquefied fuel are characterized by:
- Shortened bolt body;
- Fewer threads;
- Larger hole diameter.
In the case when incorrect operation of the stove is observed, it is best to replace not one jet, but the entire set at once, and when switching to cylinder gas, this is generally a necessity.
Why and why you need to change the jet
Nozzles for different types of gas vary greatly, therefore, when changing the type of gas-air mixture, replacing the nozzles is simply necessary. If you pay attention to the diameter of the hole, it becomes obvious that they are not the same. In this case, the diameter of the hole depends not only on the type of gas used, but also on the size of the burner itself.
After a while after replacement, negative factors may appear, indicating that the stove is not working properly. Do not rush to immediately change the jet, it may be possible to limit yourself to cleaning it
Each of the burners of the gas stove differs in power and size, therefore, for stable operation, it is equipped with a separate nozzle.
The diameter of the outlet of each nozzle is calculated for a specific volume of gas supplied from the main or gas reservoir
The more powerful the burner, the more gas it needs to work, therefore, the diameter of the nozzle requires a larger one.
Choosing a canned gas jet
As already mentioned, the propane jet has a shortened body and a smaller outlet diameter. It is not recommended to independently try to reduce the hole on your own, since even fractions of millimeters are important here. By eye, you can only improve the performance of the stove, but not achieve its ideal operation.
It is important to understand that standard jets simply do not exist. They are designed for each specific model. Modern cookers are equipped with a set of jets designed to work on propane. Some models are even produced specifically for bottled gas.
A set of nozzles for a specific model can be purchased from a specialized gas supply store or directly from a representative of an authorized supplier.
If you do not have such a set, then the issue of purchasing them is very simple. It is very easy to find the necessary product for popular models in any specialized store selling gas equipment. As a last resort, they can always be ordered by visiting the manufacturer's official website.
The procedure for performing work on replacing jets
Before transferring the gas stove to work on bottled gas, you should study the instructions attached by the manufacturer to the equipment. The manual supplied with the package contains detailed information on how to change and which injectors will be required for replacement.
It should be taken into account that at all stages of work on rearrangement of jets must be done very carefully. The use of force is not at all permissible here, since an unnecessary careless movement can lead to a breakdown, followed by a major overhaul of the equipment.
The key to a successful replacement is compliance with safety standards and a simple set of tools:
- The required number of nozzles, depending on the design of the burner;
- A set of open-end or spanner wrenches;
- Several Phillips screwdrivers of a suitable size;
- Flexible hose for connecting the cylinder
The work begins with shutting off the gas supply valve and preparing the surface for storing the removed parts and supports. Next, raise the metal grate, remove the dividers from the burners and remove them from the burner sockets.
Dismantling the burner table
To gain access to the jets, it is necessary to remove the burner table cover, which is usually secured with screws. The number of fixing screws may differ from model to model.
In any case, you just need to unscrew the screws, after which the cover can be easily dismantled. In most modern models, the nozzles are screwed directly into the body, in this case dismantling the table is not required. Consider a more complex option, where it is impossible to get to the injectors without removing the cover.
The internal structure of a gas stove
Burner bodies are attached to traverses, which are metal strips. The design of all burners is the same, the only difference is in the length of the aluminum pipe through which the fuel is supplied.
Dismantling the top panel is a great opportunity to examine the technical condition of the gas equipment. It is immediately clear what needs to be changed, where to “tighten” the loosened contacts and clean off the rust
The outlet from the tube is called a nozzle, from which the gas enters the nozzle, then enters the burner leg, mixes with air and enters the divider.
The jet provides the required amount of gas entering the burner, where the fuel is mixed with air and fed to the splitter
The latter must be carefully examined even during operation - an uneven dissection of the flame indicates that the divider is clogged, which is why the gas burner does not burn well. It is required to purge or clean it.
Methods for replacing jets
The easiest way to replace it is to simply unscrew the jet with a wrench, and install a new one in its place. But this method is not always suitable, since the tips very often stick to the nozzle, and excessive force can damage them.
It is best to first release the tips of each of the nozzles. To do this, you need to find a retainer, which is a plate with a slot. If you gently squeeze the latch with your fingers, you can easily remove it from the socket, after which, by simply pressing on the tube, the nozzle with the tip is lowered down from the mounting ring.
After removing the jet with the tip, the task of dismantling and replacing the jet itself is greatly simplified.
Trying to remove a nozzle stuck to the tip, you can simply break the tip itself. If the nozzle does not turn out without effort, then the released tip must be clamped in a vice or try to use an adjustable wrench.
Pulling off the tip will leave the O-ring inside. When installing a new jet, it must be put back on the pipe. O-ring lubrication is not required, as is the nozzle thread seal. After installing the nozzle in place, it remains to carry out the assembly of the burner table, if it was dismantled.
Replacing the nozzles in the oven
When solving the problem of how to correctly transfer a gas stove to bottled gas, do not forget about the oven, because with a change in the pressure and composition of the fuel, it can also work incorrectly. Usually the nozzle is located in a special housing behind the oven wall on the left side. The arched torch is connected to the nozzle.
In order to gain access to the burner, you need to remove the floor. For this, a specially cut hole is provided, just pull it towards you and the floor will come out. After that, you need to unscrew the burner mounting bolts, remove it and gain access to the hole where the gas comes from. This is where the nozzle is located.
During operation, the nozzle could become very attached to the nozzle body. In this case, you should not try to unscrew it with excessive force. Since if the thread is torn off, the entire body will need to be replaced. It is better, as is the case with the burners, to remove the nozzle together with the nozzle.
To easily unscrew the nozzle from the nozzle to replace it, you can process it with special tools. It remains to screw a new jet into the nozzle and carry out the assembly work in the reverse order.

Nozzles or jets are an important part of any gas stove. Only a clear correspondence of the diameter of the outlet can guarantee high-quality and stable operation of the equipment.
It is not at all difficult to purchase and replace nozzles with your own hands. The main thing is to take into account that all work must be done carefully without the use of unnecessary effort. Each of the jets has its own markings, if you look closely, it is impossible to confuse them, both when buying and when replacing.
