Master Gas Seoul Gas Boiler Trouble shooting

Malfunction of the boiler Master Gas Seoul 14, in the work of two and a half years. All this time he worked without problems. The only thing that sometimes needed to restore the pressure in the system, as it slightly dropped. Last week, after turning on the NTC mode, he stopped by mistake A4. A complete disconnection from the network helped to remove the error. In the morning the problem repeated. At the same time, I heard that the instrument changed its sound, and the pressure in the manometer became unstable. I'm advised to clean the heat exchangers, and since I've never done this, I do not know in what order what to implement. And can I do it myself? By the way, the heating system works perfectly.

To solve your problem, you should contact the specialists and the service department.

I have a Master Gas Seoul boiler. When I turn on the water supply for household needs, the temperature values on the display are constantly changing. And the water itself is then cold, then hot. The burner is working, then no. It seems to me that the problem is in the three-way valve, and its replacement is required. When I turn on the parsing in hot water from the tap, it becomes warm only after about 1 minute. At the same time, the heating works as it should, pipes and batteries are heated almost immediately. The boiler has been running for 6 months, but in summer mode, the water in the boiler is served very well.

This problem can be found on many models. Especially often this happens if the water tap is installed far enough from the apparatus itself. It's not even a malfunction, just the system responds slowly enough to changing the situation. In your case, additional heat insulation of pipes through which water enters the cranes will help. To check if you really have problems with the boiler, or if it is inertness of the system, it is necessary to measure the temperature of the water immediately at the outlet from the boiler.

I have a gas boiler Seoul 14. If it works, focusing on the air temperature sensor, then its work is somehow wrong. The temperature in the room varies from 22 to 24 degrees, although on the console I expose 26 degrees. And, when the unit stops in standby mode, the batteries cool down almost completely. Due to such temperature differences on the winding, there are shadows. To avoid this, you have to manually adjust the water temperature supplied by the battery. I can say that in general, the device works stably, but only if there are no severe frosts in the street. And yet, I would like to adjust it so that its work depends on the air temperature in

room, not from my settings. Can I implement this?

In principle, it can be done. To do this, take a pid-regulator with a thermometer and connect it to the console. However, if the coefficient is large, the inertia of the apparatus will increase. Still need to think over the circuit, duplicating the output of the controller to the button of the console.

I have a boiler with a capacity of 11 kW. Recently, it has become very noisy to work and the pump is very hot. Several times he showed an error A3, according to instructions it is the pump error. Is this a normal job? Maybe you need to find an air stop somewhere and fix it? And can it be that the water does not succumb to it at all?

Most likely, there is no cork in your pump, but the air vent should still be opened.

My gas boiler Master Gas 21 broke. He has been working for two years, and for all this time he had three breakages with A4 error. After the first problem, a heat exchanger replacement was required. A specialist in the service department said that I had opened some kind of a crane and it got dirty. In the spring of the same year again there was a mistake A4. Now on call came another master. He turned on the device, held the pressure adjustment, and he began to work without problems. And now again the same mistake. The heat exchanger is already washed, the filter has been installed for a long time. Tell me, please, is it normal that for one and a half years of work, the third time there is the same mistake?

Such an operation of the unit is incorrect. You need a competent specialist.

Wall-mounted boiler Master Gas produces a very strong hum. Tell me, please, whether I can independently switch the control card to the service mode, tried it with the remote, it does not work.

Look carefully at the fee. On top of it there should be three micro tumblers. It is necessary to transfer the two upper ones in the opposite direction, and then to adjust.

Tell me, please, on setting the speed of the fan, I'm particularly interested in the value. Today I compared the data with the instruction manual and found out that the L2 parameter should be 40, and my instrument is set to 36. Is it possible to work this way or do I need to install it as recommended in the instruction manual?

If you set the minimum gas pressure on the boiler burner lower than what is written in the manual, then there will be a strong gas overrun.

Recently, the same mistake has been repeated several times, namely, it detaches the filter in the boiler. The pressure in the system is constant, and corresponds to the recommended one. The device does not show any errors. The operation of the unit is in order, the heating is on, the hot water is supplied to the cranes. The filter knocks out, I leave it back, I restore the pressure to the system, and everything works fine again. I'm afraid to leave this situation without repair, since there is a risk that the management fee will flood. The device in the work already 3 years, and no special problems with it was not. Unless, sometimes it was necessary to update pressure in an expansion tank. How can I fix my problem?

You need to contact the service center.

Tell me, how can I increase the power of the boiler Master Gas Seoul? At purchase, the seller assured me that there is a regulator on the board that will allow to increase from 16 kW to 21, and that all these models have one board. Is it so? Can I reflash the controller?

Re-flashing should be done by certified masters.

Tell me, please, I can not find the cork, for taking air from the room. Where's she?

It is located at the top of the boiler, next to the coaxial chimney. And it is attached with four screws.
