Question: The boiler (wall-mounted gas) with twin alpa kituras, gives error 95, there is water, does not react when turned on, quiet clicks and that's it. What is the reason?

Answer: The boiler must have a water pressure of 1 atm. Check the contacts on the coolant level sensor.

Question: Kiturami turbo 13R, in presence mode everything works, it is triggered both by the temperature in the room and by the temperature of the water. In shower mode, the temperature shutdown does not work, the boiler begins to boil. Does not give errors. What could be?

Answer: It is necessary to reduce the DHW temperature. Everything is described in detail in the boiler passport. If there is extraneous noise, salt deposits are likely in the boiler itself.

Question: In the second year of operation of the Kiturami Turbo 21, there was a smell of exhaust. After switching off the boiler, air blows from the air intake manifold, i.e. reverse thrust is formed. A coaxial chimney into the wall is used. What is the problem and how to solve it?

Answer: If the chimney is installed in the area of ​​the wind support, in case of wind, when the burner is turned off, the exhaust can enter the interior of the room. It is necessary to remove the chimney from the wind support zone.

Question: Which Injector should be installed in Kiturami Turbo 13P - 0.5x60 or 0.5x80 (this was in the new one)? And what will be the effect of the installation in this boiler 05x60?

Answer: 60 and 80 is the fuel atomization degree. After these values ​​comes the letter S, P, H - corresponds to hollow, half-half and full spray. With a low-power boiler, almost any nozzle will do. We recommend adjusting the air supply (with a gas analyzer).

Question: Diesel boiler Kiturami Turbo100R. CTR5000 - shows t +92 and is not reset. The burner does not start. How can this be eliminated and is it possible to turn on the burner without this block?

Answer: Most likely the boiler control panel is faulty. The boiler can work without a control panel, for this you need to disconnect the wires of the control panel from the boiler. The only problem is, the boiler will run at maximum power.

Question: Problem with turbo 30 r kits. Natural gas. Shows error 01. From the previous answers it follows that there is a problem with ignition. Some kind of flame sensor. How do I resolve the error? Where is this sensor located?

Answer: The flame control sensor is located on the burner, two wires fit to it, two yellow or white and orange.

Question: The STSO 30 boiler is gas, in intensive heating mode (tap button), in addition to water in the shower, it heats up the coolant in the heating system. It seems to me that this should not be so with a 2-circuit boiler. Tell me what you can do?

Answer: We recommend installing a non-return valve on the return pipe after the sump, in front of the pump. Its resistance will prevent self-circulation through the heating system. With hot water supply, the volume of heated water will increase.

Question: Tell me about the floor-standing boilers with the ksog and tgb kiters - is there a built-in boiler and electric ignition?

Answer: These boilers are of the boiler type, a heat exchanger in the form of a coil is used for hot water supply, electric ignition.

Question: Tell me please, on kitura 13, the fan motor does not start the first time, knock slightly - it starts. What could be the reason?

Answer: There may be several reasons: low voltage of the supply network, failure of the capacitor of the electric motor, turn-to-turn circuit, moisture ingress into the bearings.

Question: Kiturami stso13 after the error ep01, after how many minutes it restarts on its own. Is it an error and a complete stoppage of the boiler before restarting manually?

Answer: The boiler performs two test starts, if the start-up did not occur, it goes into error mode. Most likely, there is not enough gas pressure or low voltage, the air supply is not regulated, etc.

Question: Boiler 13 STSO first started up with error 01, after repeated attempts to start, error 01 is repeated. Some owners write to clean the photocell, tell me where it is installed and how to clean it correctly.

Answer: Error code 01 - the flame monitor does not see the flame. The flame sensor is located on the burner (two yellow wires and a black plastic cylinder). it is necessary to carefully pull it out of the mount (turning to the left, to the right) and wipe it with a clean dry cloth.

Question: I have a turbo 17 diesel kit, it gives error 01 and stalls right after the start. What should be done to fix this?

Answer: Error code 01 - no combustion. If ignition nevertheless occurs, it is necessary to remove the flame monitor located on the burner from the burner and wipe it with a dry cloth until it is in perfect condition.

Question: Diesel boiler KITURAMI Turbo R21, room temperature controller CTP 5000, house area 98 sqm, radiant heating system, number of radiator sections 120, coolant volume about 100-120 liters, house on the 2nd floor is sufficiently well insulated, the chimney passes through the house on the roof, a container with fuel in an insulated room. Now the question is, it seems to me that the boiler power is excessive for such conditions, is it possible to change the burner to R13? Will this reduce the consumption of kerosene? Will the fuel pump need to be changed?

Answer: According to your description, the power is somewhat excessive. It is not necessary to change the burner, fuel pump, etc. It is necessary to install an injector with a lower capacity and adjust the fuel pump for this injector. You will achieve a reduction in power, respectively, and a decrease in fuel consumption.

Question: The boiler is stso 13. It always gives the error err01. He worked on summer diesel fuel, could this be the reason? And yet, the fine fuel filter is only half full. That is how it should be?

Answer: Error code 01 - no ignition. There may be several reasons: poor fuel supply (check the fuel supply to the boiler), the nozzle is clogged (the nozzle needs cleaning), the photocell is dirty (the photocell needs to be cleaned). Do not forget that the fuel container must be above the level of the boiler fuel pump, then the fuel filter will be completely filled.

Question: Problem with the kiturami twin alpha-16 gas boiler. They turned off the light and after turning on the light (there is a voltage stabilizer), the boiler began to give error 95, pressure testing was carried out through the system - there is no air in the system. It gives error 95, the pressure is normal, turns on and turns off immediately. How do I fix this?

Answer: The boiler water control sensor may be out of order. It is necessary to check the sensor, if it is faulty, replace it. It is also possible that the control board is faulty.

Question: Kiturami R50 diesel boiler. Is it possible to clean the fuel gear pump BFP 52K R5, if so, how to do it? The boiler starts up, turns off after a few minutes, gives an error 01. Changed the nozzle, the fuel filter, completely cleaned it of ash, but the pump does not supply fuel. What could be the reason?

Answer: It is necessary to remove the fuel pump by first unscrewing the three fastening screws, the fuel supply pipe to the hydraulic cylinder. Unscrew the four hexagon screws from the end part, remove the cover. Under the cover you will see dirt deposits, water droplets, and also a mesh filter. All this must be rinsed and wiped off. The program plate does not need to be removed. It is necessary to remove the two solenoids of the valve with coils, also rinse and wipe.It is imperative to check the coils for breakage. Reassemble in reverse order.

Question: There is a Turbo 13R boiler. I want to connect it to a UPS. Which UPS to Choose?

Answer: We recommend using a UPS of at least 400-500W. Teplocom UPSs have proven themselves quite well.

Question: Kiturami turbo diesel 13 R, why does it work for an hour or two and shows error 01.03 and so on. It started in cold weather. How to solve this problem?

Answer: It is necessary to check the flame control sensor, fuel filters, airiness in the fuel line, supply voltage in case of shortage - a stabilizer is required.

Question: Hello, I have Kiturami World 2000 HI DELUXE-13 C. Water flows from the expansion tank all the time. We put a hose - it goes to the sink. Previously, the expansion tank was not filled like this. What could be the reason?

Answer: Perhaps the air pressure was not added to the expansion tank in time, the membrane ruptured. The tank stopped functioning and when the system heats up, when the volume of the coolant increases, the pressure rises and the coolant flows out. Urgently needs to be replaced
expansion tank or plug the old tank and install an additional tank on the heating system.

Question: There was a problem when starting up the kiturami World 5000 13r boiler, error (Er 01). The gas valve of the boiler does not work, the inlet pressure is 28 mbar, the background pressure is 2 mbar at the outlet. The overheating sensor is working, so is the photosensor. Explain, please, the algorithm for turning on the block? How can I fix this problem myself?

Answer: Initially, it is necessary to check the supplied supply voltage, the absence of voltage to ground. At start-up, the fan is turned on first, then the voltage is applied to the ignition electrodes, the next stage is the voltage is applied to the gas valve (200 Volts DC). The regulators on the control unit work the other way around, clockwise the voltage supply to the gas valve coil decreases. When starting up, cover the flame monitoring sensor with your hand, otherwise there may be a false operation and blocking of operation.

Question: The problem with the boiler kitura p13. His fuse burned out - we replaced it, after that it started working, but at the same time nothing on the control panel lights up, only occasionally blinks. And the unit works, it doesn’t turn off - it’s even got the impression that the circulation pump doesn’t turn on. What to do?

Answer: Check the power supplied to the remote control, it should be 12-17 Volts. Check the voltage supply circuits to the circulation pump, whether a fuel heater in the fuel filter is connected (sometimes such models come across). When the remote control is turned off, the unit will operate at full capacity, limited only by the overheating temperature sensor (failure of the remote control).

Question: Boiler Kiturami 17 Turbo. Recently, in the mixer, the pressure of hot water supplied from the boiler has been much weaker. Could it be that the coil is clogged and how to clean the coil on your own?

Answer: A decrease in the DHW flow is the fact that the heat exchanger is clogged. To eliminate the defect, chemical flushing of the heat exchanger is required. Chem. reagents use various mixtures of acids, selected in such a way as to react as little as possible with a copper tube, sometimes they are even washed with a citric acid solution.

Question: Boiler Kiturami Turbo 30R. Gives error 98. The original tank is missing, the plug for the fuel tank is not involved. Replaced the CTX-1500 unit with a known good one. After the cycle, the error was repeated, while the boiler is working properly. After a day, the error disappeared, but after another two days, the error repeated itself. What could be the reason?

Answer: Error code 98 - lack of fuel. This error code only happens with a faulty control unit (in the absence of a container). We recommend that you try to change the pressure on the fuel pump and try to bleed the fuel system.

Question: Is it possible to use a boiler kitura turbo 13p without a circulation pump, in a simple gravitational system with an expansion tank?

Answer: If the natural circulation of the system is sufficient, then the boiler can be used without a circulation pump. There may be certain difficulties when using DHW. When using hot water, it will be necessary to turn off one of the supply or return taps in order to obtain the required amount of hot water (during the use of hot water, remove the self-circulation effect).

Question: Unit 21R (error 95) - the error has disappeared, the water level is normal, but black smoke is still coming out of the pipe and the boiler (by sound) somehow works differently. What could it be?

Answer: It is urgent to do the boiler maintenance. To do this, turn off the boiler, remove the burner, remove the chimney, remove the basket, pull out and clean the turbulators of soot and deposits. On the burner, it is necessary to flush the fuel filter, the fuel pump, remove, disassemble and flush the nozzle. It is necessary to clean the combustion chamber of soot and deposits (carefully, a refractory layer is poured on the bottom). It is necessary to achieve uniform combustion (the burner can be turned on in an open state, the flame must be short, reactive for the entire volume of the stabilizing pipe).

Repairing Kiturami boilers, like repairing any other complex equipment, requires special knowledge and skills that only trained engineers and technicians possess.

At the same time, non-standard situations often arise when the user of the boiler cannot call a specialist and he has to do something urgently himself.

It is for such EMERGENCIES, as well as for those users who are interested in the device of this equipment, that we post on our website video instructions for repairing Kiturami boilers.
