Remaking a gas stove for bottled gas: how to rearrange nozzles for working on liquefied fuel

I really want to see a gas stove in the kitchen, but there is no gas main next to the house? This is not a problem at all, alteration of a gas stove for bottled gas is quite possible, and it can be done without any problems with your own hands.

We will tell you in detail about the features of the operation of gas stoves connected to LPG cylinders. Consider the types of nozzles, the reasons for which their replacement is required. Having familiarized with the material, it will be possible to choose the right nozzles and easily perform work on the conversion of a gas stove.

How to determine the correct operation of a gas stove

When igniting a burner there should be no extraneous sounds in the form of claps. The flame should burn evenly, its tongues should be bluish-white, and it is not for nothing that gas is otherwise called “blue fuel”.

If, during the combustion of the air-gas mixture, yellowish impurities are observed, and the tongues of the flame acquire a red tint, then this clearly indicates the incorrect operation of the nozzles.

Yellow and red flames are evidence of malfunctioning nozzles

When transferring the stove from the main gas to the tank, all the stated disadvantages are very characteristic. And plus to this, because of improper pressure, soot emission will be observed. So immediately with the naked eye it is difficult to notice, but 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 conversion for bottled 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 nozzle (nozzle)?

Almost all gas stoves equipped in such a way that they are capable of working both on natural gas and on propane (from a replaceable cylinder). It should be noted that when switching to liquefied gas, not only the replacement of the nozzles is required, but also the installation of a gearbox, which is responsible for equalizing the pressure of the incoming fuel.

The reducer stabilizes the pressure of the bottled gas, ensuring the normal operation of the stove. It automatically maintains the pressure parameters necessary for the functioning of the equipment and prevents the reverse flow of the medium.

The nozzle (nozzle) 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 the gas enters the burner in the right volume and at the appropriate pressure. Its size determines the amount of gas required for a normal combustion process

Depending on the fuel used, there are two types of nozzles: for the supply of blue fuel from the main pipeline and for the supply of gas from a gas tank or cylinder.

The nozzles (nozzles) for natural gas in comparison with the nozzles for liquefied fuels are characterized by:

• The shortened body of the bolt;
• Fewer threads;
• The increased diameter of the hole.

In the case when incorrect operation of the stove is observed, it is best to replace not one nozzle, but the whole set at once, but when switching to bottled gas, this is generally a necessity.

Why and why you need to change the nozzle

The nozzles for different types of gas vary significantly, so when changing the type of gas-air mixture, nozzle replacement is simply necessary. If you pay attention to the diameter of the hole, it will become obvious that they are not the same. Moreover, the diameter of the hole depends not only on the type of gas used, but also on the size of the burner itself.

Some time after the replacement, negative factors may appear that indicate that the plate is not working properly. Do not rush to immediately change the nozzle, it may be possible to limit it to cleaning

Each of the gas stove burners is distinguished by its 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 certain amount of gas supplied from the main or gas tank

The more powerful the burner, the greater the volume of gas it needs to operate, therefore, the diameter of the nozzle requires a larger one.

Selection of a nozzle for bottled gas

As already mentioned, the propane nozzle has a shortened body and a smaller outlet diameter. It is not recommended to try to independently 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 perfect operation.

It is important to understand that standard jets simply do not exist. They are intended for each specific model. Modern stoves are equipped with a set of jets designed to work on propane. Some models are produced specifically for bottled gas.

A set of nozzles for a specific model can be purchased at a specialized gas equipment store or directly from a representative of an official supplier

If you did not have such a set, then the question of their acquisition is solved very simply. Finding the right product for popular models is very easy in any specialized store selling gas equipment. In extreme cases, they can always be ordered by visiting the official website of the manufacturer.

Procedure for replacing jets

Before moving the gas stove to work on bottled gas, you should study the instructions attached by the manufacturer to the equipment. The complete manual describes in detail how to change and which nozzles will be required for replacement.

It should be noted that at all stages of work on rearrangement of jets must be performed very carefully. The use of force here is completely unacceptable, since excessive careless movement can lead to damage, followed by major repairs of the equipment.

The key to a successful replacement is compliance with safety standards and the availability of a simple set of tools:

• The required number of nozzles, depending on the design of the burner;
• Set of open-end wrenches or ring spanners;
• A few Phillips screwdrivers of a suitable size;
• Flexible hose for connecting the cylinder

The work begins with the shut-off of the gas supply valve and surface preparation for storing the removed parts and supports. Next, raise the metal grill, remove the dividers from the burners and remove the burners from the nests.

Hob removal

To gain access to the nozzles, it is necessary to remove the cover of the burner table, which is usually fastened with screws. The number of mounting screws in different models may vary.

In any case, you just need to remove the screws, after which the cover can be easily removed. In most modern models, nozzles are screwed directly into the housing, in this case, the dismantling of the table is not required. Consider a more complex option, where it is impossible to get to the nozzles without removing the cap.

The internal structure of the gas stove

Burner housings are attached to traverses, which are metal strips. The design of all burners is the same, the only difference is the length of the aluminum pipe through which the fuel is supplied.

Dismantling the top panel is a great opportunity to study the technical condition of gas equipment. You can immediately see what needs to be changed, where to “tighten” the weakened contacts and clean the rust

The exit from the tube is called a nozzle, from which gas enters the nozzle, then enters the burner leg, mixes with air and enters the divider.

The nozzle provides the required amount of incoming gas to the burner, where the fuel is mixed with air and fed to the divider

The latter must be carefully examined even during operation - uneven cross-section of the flame indicates that the divider is clogged, which is why gas burner burns poorly. It is required to purge or clean it.

Ways to replace jets

The easiest way to replace it is to use a wrench to simply unscrew the nozzle 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 lead to damage.

It is best to pre-release the tips of each of the jets. To do this, find the latch, which is a plate with a slot. If you gently squeeze the latch with your fingers, you can easily remove it from the slot, after which by simply pressing the tube the nozzle with the tip is lowered down from the mounting ring.

After removing the nozzle with the nozzle, the task of dismantling and replacing the nozzle itself is greatly simplified

Trying to remove the nozzle attached 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 using an adjustable wrench.

If you remove the tip, the o-ring will remain inside. When installing a new nozzle, it must again be put on the pipe. Lubrication of the ring is not required, as is the seal on the nozzle thread. After installing the nozzle in place, it remains to complete the work on assembling 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 it can also work incorrectly with a change in pressure and fuel composition.Usually the nozzle is located in a special housing behind the wall of the oven on the left side. The arc curved burner is connected to the nozzle.

In order to access the burner, you need to remove the floor. A specially cut hole is provided for this, just pull it towards you and the floor will come out. After that, you need to unscrew the bolts of the burner, remove it and gain access to the hole where the gas comes from. It is here that the nozzle is located.

During operation, the nozzle could very stick to the nozzle body. In this case, do not try to unscrew it with excessive force. Since if the thread is broken, then the entire housing will need to be replaced. It is better, as in the case of burners, to remove the nozzle with the nozzle.

To easily unscrew the nozzle from the nozzle to replace it, it is possible to carry out processing by special means. It remains to screw a new nozzle into the nozzle and perform assembly work in the reverse order.

Nozzles or jets are an important component of any gas stove. Only a clear correspondence to 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 carried out carefully without the use of unnecessary efforts. Each of the nozzles has its own marking, if you look closely, it is impossible to confuse them, both when buying or when replacing.
