How to adjust the gas column

Gas column

People who recently bought a water heater may encounter some issues with incorrect adjustment during installation. However, companies have come up with a solution by creating devices with automatic adjustment. Today, we will discuss how to adjust the gas column.

Preparing for the adjustment of the water heater

Even though there are instructions on how to properly adjust the gas columns Bosch, Selena, and Neva, not everyone comprehends the process. Making an error right from the start can cause the device to not function as intended. It is crucial to begin the work by regulating the water supply.

To begin with, the water regulation needs to be adjusted. Making the adjustments at the last moment will result in incorrect settings. The water flow should be set to the smallest level, which is typically indicated as 6, 10, or 12 liters. You can find the specific values in the documentation.

It is important to note that only one tap should be in use.

Starting the device and adjusting the temperature

To properly regulate the hot water temperature in the device, follow these steps:

1. Fully open the hot water mixer.
2. Use the water switch to select the desired temperature.
3. Close the faucet.

According to experts, you should also take the following steps:

1. Wait until the pressure in the water mains has decreased, but the hot water is still running.
2. Rotate the water switch knob to the maximum position.
3. Adjust the gas regulator to the minimum setting until the desired temperature is reached.

For the final preparation, it is important to adjust the gas supply. Refer to the data sheet for the minimum value required for your specific brand.

Make sure to set the toggle switch to the minimum position.

Make sure to open the gas supply valve. For the "Electrolux" and "Ariston" gas columns, this should be done after connecting to the power source. However, for the "Oasis", "Junkers", and "Bosch" gas columns, you should connect them after installing the batteries.

Once the gas supply is on, turn on the hot valve and the device will begin functioning.

How to adjust the water temperature

Make sure to turn on the faucet and verify the temperature of the water heater. It needs to be increased by twenty-five degrees from its initial setting. It’s important to keep in mind that the water in the gas boiler takes some time to heat up. The adjustment of the gas column can be done using the gas lever.

Assist please! There is also an option to control the water temperature by using a toggle switch. In case the flow intensity goes up, the heating temperature will go down.

Experts strongly advise against raising the water temperature above fifty-five degrees. This has a negative impact on the equipment, as it leads to the formation of scale.

Problems with pressure

The installation process of a gas column takes a certain amount of time. Consequently, the outcome will not be immediate. It is recommended to drain the water and let it heat up again after each step to ensure accurate readings. Insufficient pressure in the device can impede normal operation.

If you encounter pressure issues, you can try the following steps:

• Take off the casing of the device;
• Loosen the locking bolt and use a pressure gauge to check;
• Remove the seal from the adjusting screw;
• Turn on the boiler;
• Set the values to maximum and unscrew the hot water taps;
• Adjust the pressure to the desired level.

For the Bosch gas column, specifically, the pressure in the nozzles can be adjusted in the following manner:

• Remove the casing;
• Loosen the locking screw;
• Attach the pressure gauge to the nozzle connection to check the pressure in the nozzles.

After that, you need to adjust the Bosch gas heater with the highest heat output:

• Remove the screw seal;
• Turn on the device;
• Open the hot water taps;
• Adjust the pressure in the nozzles using the adjustment screw;
• Put the seal back in place.

Getting rid of the faulty pressure is a simple task that can be easily checked.

To accomplish this, a few steps must be taken if the device has already been used:

1. Inspect the rubber membrane. The functionality of this component is directly linked to the pressure in the main line. When the diaphragm gets damaged or worn out, gas will not flow, and the burner will not ignite. To solve this issue, the part needs to be replaced.
2. Take a look at the strainer. It is located at the entrance to the water block. The pressure of the water decreases due to debris blocking the component. The solution to this problem is to clean the strainer.

To adjust the gas heater, one can make adjustments to the flame. The semi-automatic and automatic devices have a knob on their body that is specifically designed for regulating the gas. Using this knob, one can increase or decrease the supply of blue fuel. The overall power of the device is directly influenced by this particular component.

When the flame is increased, the gas consumption will be higher, which will result in better heating of the water. Experts recommend adjusting the burner by altering the gas transfer rate. Once the desired burner intensity is achieved, the water pressure knob can be utilized. To modify the combustion temperature, it is advisable to switch between the "Winter-Summer" modes.

Fine tuning

These devices are equipped with a single gas heater temperature regulator. The regulator allows adjustment of both the heating temperature and power. The device is also equipped with a self-diagnostic system that evaluates the operation of its components when it is turned on. In case of any problems, a red light will illuminate and the device will be blocked from starting. To resolve this issue, it is necessary to adjust the water pressure.

• First, remove the batteries from the compartment;
• Then, switch off the microswitch;
• Next, connect a power source;
• After that, turn on the hot tap and activate the microswitch;
• Ensure that the pressure on the burner is at its maximum;
• Once the settings are saved, an orange lamp will illuminate indicating that the adjustment is complete.

In other models, the water temperature can be regulated by using a toggle switch and adjusting the water flow force.

Important: It is strictly prohibited to exceed the maximum temperature indicated in the instructions.

Regrettably, adjusting the settings as per the instructions is not a straightforward task. Each system has its own unique values. If you encounter difficulties in manually adjusting the temperature regulator of the gas heater during its operation, it is advisable to seek professional assistance.

Poor pressure

Let’s discuss the factors that influence the water pressure in the gas heater:

1. Potential blockages. Each water pipe has the tendency to become obstructed by debris. For instance, in the case of an Electrolux gas heater, the blockage typically occurs in the mesh filter, which can be filled with lime and rust. When the water flow is restricted, the pressure will be significantly reduced.
2. Technical issues. In this scenario, limescale can accumulate inside the heat exchanger. When the water is shut off and then turned back on in the gas column’s water unit, a "hydrostroke" can occur, allowing some of the scale to enter the mixer and cause a blockage.
3. The importance of device power. The power of the Bosch gas column and other models is a crucial factor. It ensures a strong pressure within the system. Insufficient power (below eight) will result in minimal pressure. To ensure efficient operation of the gas column’s water unit, it is recommended to purchase a device with a capacity of eight to ten kilowatts.
4. Scale build-up. Scale typically forms in metallic containers that heat water, such as the heat exchanger in a gas column. When hard water is involved, scale accumulates on the heat exchanger’s walls and eventually transfers to the tubes, leading to decreased pressure.
5. Preventive measures. Regular maintenance is essential for all devices, including gas columns, to prevent clogs and maintain optimal water pressure. Neglecting proper care can often result in decreased water pressure.

If the filter becomes blocked, it is advisable to remove this component from the device. Clean it using a firm brush and water. In the event that the filter gets damaged during the cleaning process, it is recommended to replace it with a similar one.

If the hot water pipe gets clogged, you should run cold water in the opposite direction. Remove the plug and place a container under the device to collect water. Unscrew both taps and close the spout with your finger. It is believed that the force of the cold water can push the blockage forward.

Using chemicals that remove limescale in the water column is not advisable. Their composition can easily damage the metal surface. The optimal solution is to use citric acid, which can be dissolved in hot water.

What malfunctions can occur in the column Neva Lux

The Neva Lux gas column will display an error code if there are any problems.

Here are some common error codes that can also occur with the Neva Transit gas heater:

E7. If the appliance fails to turn on after seven attempts, it may be due to faulty electric valves, soot buildup on the electrode, a malfunctioning ionization sensor, or a blocked gas supply. To solve this issue, you will need to replace the defective parts or clean the soot using a brush.

L0. This error code indicates that there is insufficient fuel supply. Possible causes include poor water pressure, a drop in temperature, or excess gas column pressure in the Neva Lux. To resolve this problem, you can adjust the temperature, install a reducing reducer, and clean the radiator to remove any scale buildup.

E0. The device shut down automatically. There seems to be a problem with the fuel flow into the device. The recommended solution is to inspect the gas valve of the Neva Lux gas column. It is likely that the gas supply temporarily ceased.

E8. This issue is connected to the draught sensor. Typically, it occurs when the chimney is obstructed or the sensor is damaged. To resolve this, you can clean the chimney yourself or seek assistance from professionals. Another option is to replace the sensor with a new one and ensure that its contacts are securely connected.

Other device problems

Aside from error codes, there are also other issues that are commonly associated with the Neva transit gas column:

1. The device operates noisily. To address this, adjust the water regulator and lower the pressure.
2. Gaskets in the pipe connection areas protrude. This problem can be resolved by replacing the affected gaskets.
3. The display ceases to function. This can be caused by faulty contacts, a broken display, or a defective temperature sensor. To fix this, replace the necessary parts and the display itself.
4. The appliance no longer illuminates. This problem is also typical of the Zanussi gas column. The malfunction may be due to a stretched membrane, overheating, or a broken component of the device. Replace the faulty part with a new one to resolve the issue.

If you decide to tackle the repair yourself, be prepared to invest a significant amount of time studying the repair material and figuring out how to properly set up the gas column. It’s important to note that the end result may not match the instructions in the repair literature and could even be a disaster. It’s highly recommended to leave this task to professionals for the best outcome.
