Should check whether the oil solenoid valve is open? If it does not ignite after opening, you should check whether the high-voltage ignition electrode is good, whether the distance is correct, and whether the high-voltage wire is broken. Next, check the ignition transformer.

What should I do if the GW secondary fire of the Riyadh combustion engine does not start?

First short-circuit T6T8, if it has not been opened, check whether the 2-stage servo motor of the damper operates, and see if the 2-stage solenoid valve is powered on, it is possible that the valve is damaged and the power is not opened, or the servo motor of the damper is not adjusted properly or damaged. It is also possible that the controller is damaged and there is no 2-stage fire output.

What to do if the Riello burner fails to ignite?

1. If you can’t click, you have to check when it was locked. Check the fault diagnosis reported by the program-controlled box, and find out the cause of the lock according to the number of times the red light flashes.

2. The red light of the program control box keeps flashing, and the burner can still work normally. See if you have remote control and whether the 5th corner is grounded. It is also possible that the program control box is faulty.

What is the reason why the Riello natural gas burner sometimes fails to ignite?

When the burner is ignited, it often encounters the situation that it cannot be ignited, and there are many reasons for it. Let's talk about the main reasons and solutions:

(l) The air door opening of the burner is too large or the opening of the chimney baffle is too large, resulting in too much air entering the furnace. In this case, the burner is not easy to ignite.

The solution is: reduce the opening of the damper of the burner and the opening of the chimney baffle, and then adjust the damper and baffle to a suitable opening after ignition.

(2) When the pressure of the fuel oil is greater than the pressure of the atomized steam, the burner is not easy to ignite.

The solution is to adjust the fuel oil pressure to about 98kPa lower than the atomized steam pressure.

(3) The pressure or temperature of the fuel oil is too low, you should contact the relevant unit to increase the pressure or temperature of the fuel oil.

(4) If the pressure or temperature of high-pressure gas is too low, you should contact the relevant unit to increase the pressure or temperature of the gas.

(5) The fuel oil contains too much water, so you should contact the relevant unit for dehydration in time.

(6) High-pressure gas contains too much oil and water, so you should contact the relevant unit for deoiling and dehydration in time.

(7) If the amount of steam is too large and the amount of fuel oil is too small, the steam valve should be closed and the fuel oil valve should be opened appropriately to achieve a suitable oil-steam ratio.

How to deal with the red light of the Riello burner?

The red light on the Riello burner is because the red light has been on before the power failure, and it cannot reset itself without manual reset. Press the reset button and wait for no more than 3 seconds to turn the yellow light, let go, the burner starts to start, when it jumps to the green light, because the power of the burner is too high at this time, when you hear a sound (bang), it suffocates, and the electric eye If a stable flame signal is not established to the programmer, the programmer locks, and the red light turns on again immediately. The motor stops working and the fuel valve closes at the same time.

the

The solution is: first, check whether the outlet of the combustion chamber and the flue are blocked; second, reduce the power of the burner (while reducing the supply of fuel and wind.

Troubleshooting method for maintenance of Riello burner

The common faults of Riello rs70 series burners are actually the same as those of burners of various brands and models, and there are no special faults.

Riello burner does not ignite alarm failure

This phenomenon of the Riello burner indicates that the burner has failed to ignite. It should be checked to confirm whether the gas supply is normal, whether the ignition high voltage is normal, and whether the ignition electrode is damaged by ablation. If no abnormalities are found in the above inspections, the working status of the burner should be readjusted.

Troubleshooting method for maintenance of Riello burner

A Riello burner used on a boiler needs to be ignited several times before it can start working, and the cause of the failure has never been determined. Then the situation became more serious. No matter how I clicked it, it didn’t work. I pulled out the tip of the gun and carried out an ignition test. There were sparks at the top of the two high-voltage lines, atomized light oil was sprayed out from the nozzle, and the fan was working normally. Installed in place and then ignited, the fault remains the same. For this type of burner maintenance, it is judged that the relative ratio of air and fuel has not been adjusted properly to eliminate the failure of related components. But based on experience, the main root cause is that the current air volume is large, and the spark of the transformer is not enough to ignite the fuel... In the case that it was easy to use in the past, there are the following possibilities:

1) Insufficient transformer power

2) The pressure of the burner oil pump is insufficient, the atomization is not good, and the spark cannot be ignited

3) Other reasons cause the relative back pressure to decrease to negative pressure. The solution when the burner cannot be repaired by a professional: replace the transformer, oil pump, oil nozzle, clean the oil circuit and replace the place that may have problems, and then adjust the damper and oil pressure.

The r130 Riello burner will go out after one or two seconds of ignition, and the fault code is that the red light flashes twice

The red light of the Lili Road gas burner flashes twice, indicating that the burner has failed to ignite and needs to be repaired.

Common faults and troubleshooting methods of burners

When a failure occurs, the main problems affecting normal operation should be checked first:

the

1. Is there electricity?

the

2. Is the gas pressure of the gas supply network normal, and is the ball valve open?

the

3. Are all regulating devices, such as room and boiler thermostats, water volume controls, air and gas pressure switches, etc., adjusted correctly?

the

4. Has the air volume and gas flow changed during combustion?

the

If the failure is not caused by the above reasons, the interlock must be removed, the burner must be connected, and the relevant functions shall be tested.
