Troubleshooting due to which the geyser does not ignite

There is a turbocharged geyser with electric ignition. When hot water is turned on, the column clicks, but does not light up. An electric discharge is heard, the fan turns on.

The first step is to inspect, for this we remove the column cover. It is mounted on four bolts: two from the bottom, two from the top. We also remove the knobs for the flame regulator, temperature, winter-summer mode. On examination, everything seems to be intact, the wires have not burned out anywhere, water does not leak anywhere.

The principle of operation is that when a water flow appears, the gas valve is activated, an electric discharge is created, the gas is ignited, and at the same time the fan is turned on to pull the spent combustion products out into the street. If the water pressure is insufficient or the hood does not work, the gas goes out, the column turns off.

So, open the faucet and see what happens. Water rustled through the tubes of the heat exchanger, the electrodes gave a discharge, the fan turned on, but the gas did not ignite. Let's check if the relay (microswitch) is working, which works with sufficient water pressure and opens the gas supply valve. To do this, turn the tap again, the relay tongue should move away.

It works, which means that the pressure is sufficient for the operation of the gas column. Now let's check the operation of the gas valve. To do this, use a screwdriver to move the same tongue without opening the water. If there is a spark on the electrodes and the fan starts, then the gas valve is working.

The fault was found quite quickly, the ignition electrode did not spark. There are two of them: extreme. The one in the center is the control one, in the absence of a flame, it turns off the gas supply.

Oasis geyser device (with diagram)

The inside of a standard hot water gas equipment is represented by:

• plate heat exchanger with water tube;
• gas burners;
• waste gas collector;
• piezoelectric element or automatic electric ignition.

The electronics are powered by batteries, from the mains or using a built-in miniature turbogenerator. Adjustment of the temperature regime of water in budget models is carried out by a water reducer or the so-called frog, and in more complex and modern ones - in automatic mode via electronics.

Gas boilers are characterized by the presence of an open or closed combustion chamber, and the difference between the models of the first type is represented by the intake of air masses directly from the room.

Exhaust gases are removed naturally through the chimney system, or using forced ventilation and a coaxial chimney.

The components and main components of flow gas equipment that require competent maintenance and explain the principle of operation are listed in the diagram.

Modern gas water heating equipment Oasis is equipped with protective automatic shutoff of the gas supply

Modern water-heating equipment is characterized by the presence of protective automation, represented by flame control and a traction sensor, which allows you to shut off the gas supply in automatic mode.

How to connect and set up

Gas water heating equipment is installed in a kitchen or any other non-residential, but heated room in accordance with the gasification project and in accordance with the basic requirements of gas supply organizations:

• hot water equipment is connected to a chimney system with good and stable draft;
• it is forbidden to mount the equipment above any sources of open flame or heating devices;
• before installation, permission from the gas service specialists to install the equipment must be obtained;
• the installation of the unit is carried out by the gas operating organization or other licensed companies;
• installation is carried out on flame-retardant surfaces, including brick, concrete and ceramic tiles with mandatory insulation with galvanized sheet and BTK;
• the protective layer of insulation must protrude beyond the housing at least 10 cm along the entire perimeter;
• the column is suspended using brackets fixed in the wall, attached to the gas equipment;
• all shut-off valves in the form of water supply to the gas supply to the unit are located in an easily accessible place;
• a filtering system is installed in front of the water-heating equipment to purify the water supplied for heating;
• for connection to the water supply, pipes or flexible hoses with an internal diameter of 13-14 mm or more are used.

Below is a standard gas boiler connection diagram.

Connected gas equipment must be registered

After installation and until commissioning, the water heater must be registered with the gas service.

Sources of the accident

There are several reasons for the failure of the burner, the main ones are the following factors:

1. Lack of traction.

For any model, be it the Neva, Oasis or Vector, the flame goes out or does not light up due to the fact that the chimney is often clogged with dust, dirt and foreign objects. In modern equipment, in this case, a protective valve is activated, which automatically shuts off the fuel supply to the gas column. This is because the products of combustion are not discharged in full and in accordance with the technical requirements.

To verify the malfunction, you need to check the traction. To do this, open a window and bring a lighted match or a sheet of paper to the pipe. If the chimney is clogged, the wind will not be felt, so the geyser does not light up. The cleaning of the combustion waste disposal system is carried out by specialists

It is important not to miss this moment, as the exhaust gas enters the room, which can lead to serious consequences.

An ingenious way to almost NOT PAY for electricity! A clever meter that saves electricity Pays for itself in 2 months!

Sometimes the automation works when the hood is turned on, located nearby, the flame goes out or does not appear. If the device has a large power, it interferes with the removal of waste, so you should never install two units in one place, especially in small rooms.

2. Malfunction of sensors.

If the igniter flame goes out, it is necessary to inspect the device that controls the exhaust of gases. To do this, disconnect the wires and check the resistance using a special device. The indicator must be indicated in the passport, if it does not reach the optimal value, the sensor will have to be replaced. The burner goes out when the thermocouple breaks. In this case, the gas column does not ignite due to low voltage, the optimal parameter of which is 10 mV.

3. Discharged batteries.

The main function of the batteries is to keep the valve open during operation. The service life of the elements is no more than a year, therefore, manufacturers of such gas units as the Neva recommend changing batteries on time. In addition, the reason that the burner does not ignite may be a malfunction of the piezoelectric element or the power cable. It is necessary to disconnect the wires and check them for internal and external breaks. If there is still no spark, the column does not turn on, then the source of the problem is different.

4. Blockage of the inside.

If dirt and soot get into the gas supply tunnel from the fittings to the burner, the flame goes out or does not ignite. The injectors need to be cleaned. If the fuel pressure is not adjusted, a characteristic whistle will be heard, flame separation appears, then it disappears.Also, a burner of the wrong diameter can create such a malfunction. In this case, you need to correct the gas supply or replace the elements. When airing, the gas column ignites, but immediately goes out. To eliminate the defect, you need to unscrew the nut on the fitting and bleed the air, then return the mount to its place, fix it and check if the burner goes out.

5. Deformation of elements.

If the water is too hard, scale appears in the pipes, which gradually clogs the filters, so the gas unit goes out or does not turn on. The grate is taken out, thoroughly cleaned. If it has been damaged by deposits, it is better to replace it.

The membrane of the water supply unit often breaks, so the column does not turn on. To determine its condition, remove the top cover of the case. The plate should not be in cracks and gaps, has the correct shape, smooth and even. In case of the slightest deformation, it will have to be replaced. It is better to choose a part made of a durable and elastic material that is resistant to temperature fluctuations and the influence of scale. Install the membrane carefully, crimping the fasteners around the perimeter.

6. Water pressure.

As in the draft situation, the automation blocks the gas supply; if the supply is poor, the burner immediately goes out. It is worth contacting the utilities to find out the reasons, turn off the unit until then. You can use the column only if the water pressure is normal. In private homes, the pressure is increased using a compact station and a regulator. If the column turns on and works normally, and the water is still cold, the device may not have enough power, the parameters are noted in the passport.

Scale on the heat exchanger - how to fix

The need to clean the heat exchanger is usually caused by the following reasons.

• The water takes a long time to heat up.
• Bad water pressure.
• The overheating sensor is triggered and the column turns off.

If the above happens with the column, this means that it is necessary to clean the heat exchanger, since a large amount of scale has formed in it.

Step-by-step instruction

Cleaning the heat exchanger consists of the following steps.

1. It is necessary to shut off the water supply to the heater with a valve, and dismantle the heat exchanger by disconnecting it from the water pipes. If cleaning is done infrequently, it is recommended to use a lubricating spray for dismantling, which makes it easier to unscrew the oxidized nuts. After processing the nuts with a spray, you must wait 15-20 minutes and start unscrewing them.
2. After dismantling the heat exchanger, you can start cleaning it. To clean the scale, you can use a solution prepared at the rate of 100 grams. citric acid in half a liter of hot water. Using a watering can, the solution is poured into the heat exchanger, and it remains there for 12 hours.
3. After that, it is necessary to drain the solution and rinse the part thoroughly with clean water. It is necessary to thoroughly clean the heat exchanger from scale residues, as it can clog the pipes, blocking the flow of water. This can be done with pressurized water or compressed air.
4. The final stage, at which it is necessary to install the heat exchanger in place in the heater after changing the sealing washers.

Geyser flame adjustment

Another way to adjust the water heater is to change the gas supply to the burner.This is done by adjusting the flame. On the body of automatic and semi-automatic hot water boilers there is a gas adjustment knob that reduces and increases the supply of blue fuel. The power of the column depends on this lever.

With an increase in the flame, the heating occurs more intensively, the gas consumption increases. Experts recommend changing the gas flow rate to fine-tune the burner flame. After choosing the intensity of combustion, for additional adjustments, use the knob for changing the water pressure. Another way to change the combustion temperature is to change the winter-summer mode.

To reduce gas costs in semi-automatic models, you can adjust the igniter. The adjustment of the wick is carried out by means of a special bolt on the pilot burner. Changes must be made carefully. If the pilot flame is reduced too much, this will cause the water heater to refuse to work. A strong increase in the intensity of the flame will lead to a significant waste of gas.

The column refers to complex gas equipment. Fine-tuning and maintenance must be performed by a licensed wizard. You can independently change the intensity of the water flow and gas pressure by adjusting the operating mode of the water heater for yourself.

Do-it-yourself troubleshooting and troubleshooting

Even with proper installation and proper maintenance of water heating equipment, the owner of a gas burner may encounter some malfunctions that most often occur after a long operation of the unit.

The activities of Forte Home GmbH, representing gas water heaters under the Oasis brand, are based on absolute financial transparency and complete loyalty regarding the relationship between customers and partners, taking into account the accumulated unique experience. Thanks to such features of activity, the water-heating equipment "Oasis" becomes more popular every year.

The lineup

The range of the company is quite wide. Consumers are presented with classic, chimneyless and turbocharged models, different in their power, principle of operation and appearance.The most popular are the columns of the middle price category, which allow for uninterrupted supply of hot water for quite little money. Among them, a number of models can be distinguished, customer reviews of which are most common.

Oasis Glass 20 VG is a flow-through appliance that requires a chimney and has a unique design. Due to its small dimensions, which are 34x59x14.5 cm, the column harmoniously fits into small rooms, does not clutter up the space and does not spoil the interior. The model is powered by batteries, which ensures complete energy independence of the unit and makes its operation independent of power outages. The column starts automatically immediately after opening the DHW tap at a pressure in the water pipes of at least 0.02 MPa. The column is equipped with an RCD, a thermostat and an anti-freeze function, and the presence of the Winter-Summer mode allows you to save up to 70 cubic meters of gas per year. The performance of the model is 10 l / min, which, with an optimal power of 20 kW, is enough for the bathroom and kitchen. The efficiency of the device is 90%, and the cost varies from 4 to 4.8 thousand rubles.

"Oasis TUR-24" is a device from the "Turbo" series, powered by the mains and does not require regular battery replacement. The ignition of the gas burner occurs synchronously with the opening of the tap. The model does not require the arrangement of a chimney: the removal of combustion products occurs forcibly with the help of an electric fan built into the housing. Exhaust gases are discharged to the street through a corrugated pipe.

The column capacity is 12 l/min.The turbocharged model is equipped with a liquid crystal display that allows you to monitor the temperature, and an overheating protection that turns off the device automatically if the permissible temperature is exceeded. The dimensions of the column are 33x62x18.5 cm, the cost is 9 thousand rubles.

"Oasis B-12W" is a miniature flow-through chimneyless model with dimensions of 29x37x12 cm and a capacity of 5 l / min. It is usually installed on one of the intake points, which is due to the rather low power, not exceeding 11 kW. Ignition is made from replaceable batteries. The device is equipped with a copper heat exchanger, overheating protection and a display. The cost of the column is 4 thousand rubles.

"Oasis 20-OG" is an economical non-volatile device designed to operate on liquefied gas from cylinders and is used in homes that do not have a connection to central networks. The model is equipped with the "Winter-Summer" function, gas control, thermometer and ionization sensor. The performance of the heater is 10 l / min, the power is 20 kW, and the cost does not exceed 5 thousand rubles.

Not enough charge

When you open the water, you observe a normal flow, when you turn it on, there is a characteristic click, a spark is formed and everything in general is visually good. But there is one noticeable point: the burner itself in the gas column does not ignite. If you look out the window, there is no flame. This is the reason why there is no hot water. The owner does not have hot water, because of this fact there is a lot of inconvenience. This cause must be eliminated as soon as possible.

The reason for the malfunction and lack of hot water lies in a completely simple phenomenon. When the batteries stop working, the column stops functioning.It does not heat up and therefore the hot water supply stops.

The charge of the battery in the last stages is only enough for the formation of a spark. Therefore, visually you observe a spark, there is also a noticeable click. But the energy of the battery is not enough to ignite the burner itself.

Replacing the batteries yourself is not difficult. To do this, open the box with batteries and pull them out. Next, you should replace with new high-quality powerful batteries.

More about batteries

Battery polarity matters. If you insert batteries without taking into account their polarity, the column will not light up. Batteries can sometimes get stuck in the box, so keep an eye on them.

Batteries are replaced with new functioning batteries subject to two main criteria:

• the polarity of the batteries must be taken into account;
• the closing of the box, which is intended for batteries, should be done until a characteristic click.

Batteries used in gas water heaters must be standard D (in other words, barrel batteries). Salt options are not suitable because they have the ability to quickly fail. In most cases, alkaline batteries are used for gas water heaters. In another way they are called alkaline batteries.

Often there are cases when a person purchases batteries, but they do not light the column. Here, too, several questions arise, why even new batteries cannot cope with their functions. At this stage, the owner may also be embarrassed and look for the cause in a completely different way. In order not to find yourself in such an unpleasant situation, you need to wisely approach the choice of batteries for the functioning of the gas column. A few tips to keep in mind..

Battery Tips

It is not advisable to choose too cheap. In this case, it is recommended to choose more expensive batteries (normal ones cost about 200 rubles). If you buy cheap ones, then they most likely will not work normally, which means that in the future you will need to overpay

Therefore, purchase initially good quality expensive batteries;
Pay attention to the expiration date of the batteries;
As for brands, Duracell and Energizer brands are preferred.
The battery must be alkaline or lithium.

It will be more informative to use a specific multimeter tester that accurately determines the charge. Everyone can use such a tester, it will not be difficult. This method is convenient and practical to use, and you can buy a battery tester at any store.

Independent repair of gas boilers

Before you start repairing a gas boiler with your own hands, it is necessary to identify the cause of the breakdown. Various elements of heating equipment can fail. Most often, the causes of breakdowns are: violation of operating requirements, poor quality of parts, shocks.

Volatile boilers often fail due to reset. Therefore, the repair of the heat unit must begin with checking the settings and the presence of open contacts. Performing troubleshooting, the device is turned on at full power in the "Winter" mode. Repair of heating gas boilers begins with this step.

Repairing gas heating on your own is far from always possible, and only if the malfunctions are simple and noticeable.Only specialists can deal with complex breakdowns

Also, do not forget that gas boilers are dangerous equipment, so you need to handle them carefully, and in no case try to repair the gas pipe and safety elements yourself.

Video about repairing a gas boiler with your own hands:

An indispensable attribute of any heating system is a boiler, which acts as a heat generator for heating a home.

The modern market for heating equipment is saturated with a very wide range of boilers of various types. But a special place in this assortment is occupied by gas boilers, which are gaining more and more popularity every day.

This trend is due to the fact that units of this type are very efficient and economical devices for heating a country house and even an apartment. In order for the gas boiler to function smoothly and stably, it is necessary to properly care for it.

One of the types of such maintenance is cleaning the gas boiler from soot and other contaminants. Let's talk in more detail about why cleaning a gas unit, as well as in what ways this can be done.

1 What are the types of Oasis speakers?

Oasis water heaters are divided into two types according to the principle of operation:

1. Flowing water heaters.
2. Storage water heaters.

The mechanism of action and heating of water depending on the type of device will be different. Another type should also be distinguished - this is the Oasis Turbo gas water heater, as well as the Oasis turbocharged gas water heater. Most often they are installed in large organizations, apartments and large private houses.

Geyser in the kitchen

All of the above devices should be installed where there are no stationary chimneys. All these devices work from the mains and do not require additional batteries. The operation of such a column is carried out in the forced emission of combustion products. Turn on and off the Oasis turbocharged geyser by opening the tap. It can also be installed standalone.

Advantages of gas water heaters Turbo:

• Modern compact design;
• Forcibly throws combustion products out;
• The security system is built into the column itself;
• The presence of a control panel and a liquid crystal block on all models of gas water heaters Oasis;
• High efficiency;
• Simple and uncomplicated adjustment of the Oasis geyser.

flow columns

Now we will analyze the popular flow column. If you decide to put such a column in your house, then you don’t have to worry about the fact that you will be left without hot water, even despite the slight pressure.

Geyser manufacturer

It should be noted that Oasis water heaters are made in such a way that they have different boiling water capacities. In addition, we can say that the device is gas Oasis columns are made according to the flow type. Such a column can produce from 5-15 liters of hot water within 1-2 minutes.

But the positive aspects of the Oasis flow columns:

1. Structures are enabled automatically.
2. This column does not depend on electricity, but works due to replaceable batteries.
3. Reasonable price for a gas water heater Oasis.
4. Clear and legible instructions for the Oasis geyser.
5. The presence of a regulator in the column that controls the heating process depending on the external temperature and what time of the year it is at this stage.
6. It is economic that allows to minimize costs of the consumer.

One of the Oasis views

It should also be mentioned from consumer reviews that the manufacturer of the gas column Oasis constantly thinks and improves the quality of its products for the better.

The disadvantages of the Oasis instantaneous water heater is its high cost. Although the device is durable and quickly pays off from the consumer.

storage columns

The storage and flow devices mentioned above differ greatly from each other in terms of the principle of operation. If we talk about a storage heater, then the principle of operation is that the water in it is heated in a large tank. It should be noted that flow columns do not have such a storage tank.

Oasis column device

If we talk about the positive points, then they are as follows:

• A simple repair of the Oasis geyser can be done by a person who does not have special skills.
• There is always plenty of hot water available.
• Economy at work.

If we talk about the negative aspects of the Oasis storage columns, then naturally it has a large size and high cost.

Also, among customer reviews, they constantly notice that the Oasis column is problematic to place in a small apartment. It is better to buy it for those people who have private houses. It has a huge tank that can provide hot water to the whole family, especially the presence of such a device is necessary where there are small children.
