Rg3 oil boiler won't fire Has power and oil Stats are up and programmer set to run Reset button pressed 4 times over 4 days no response or noises What next ?


I guess maybe the programmer/timer or other circuitry is defective and preventing power being supplied to the spark generator and/or fuel pump/combustion fan or perhaps the flame monitoring circuitry isn't working.

When a light oil burner starts the ignition spark is switched on first followed by the combustion fan and then the fuel pump supplies fuel to the spray nozzle under pressure and produces a jet of fine mist which ignites. If the flame dies the flame monitor signal also dies and the safety circuitry shuts off the pump.

That is roughly how many light oil burners work and as you now know there is a lot that should be happening, that is unlikely to happen if everything isn't in good order due to the requirement for safety.

Some Rg3 information is available to download if you are interested but if you want your boiler working quickly I advise you contact a professional.

I have a riello burner 40 it will fire and come to temp but wont refire, goes into lockout


My first guess would be that it sounds like a clogged oil filter, air in your fuel line, is piping overhead, or leak in a fitting or connection causing it to loose it's prime when running.

I have also seen primary controls that are faulty do this, watching the complete cycle of the run time will give you more clues as to when the control actually locks out. Does it lock out during the run cycle as the boiler reaches temp.? If so,check for oil line and suction issues as stated above.

If it locks out on start up after reaching boiler set temperature, if hitting reset right away burner doesn't start and lock out occurs with no motor engaging, check motor (Note: Some motors when HOT will not kick in when powered, but after they cool down naturally they start, motor shaft may also be bound up tight, replacement is necessary) if burner motor spins but does not fire, check for fuel flow to the nozzle, be sure oil is pumping to the nozzle, if it is, clean cad cell eye, and check transformer for spark, if all is good.. replace primary control.

Disclaimer:
Of course all this information is technical troubleshooting information and should be performed by a Licensed Technician, not knowing how to properly test for flame failure can cause injury, fire or worse! Consult a technician in your area if you are not proficient at oil burner repair!

Riello burner


You need to measure the manifold pressures before and after the gas valve and adjust accordingly to fuel used, 3.5" NG or 11" Propane.

My oil boiler keeps locking out


turn off the power to the system and then open up the transformer using a 5/16 nut driver. The transformer is hinged and it will flip out of the way. Look for a small black cylinder with yellow wires. Clean off the eye. Then turn off your oil supply to the burner. Using a 7/16 wrench, unscrew the very small copper line at the end where it enters into the burner housing, then spin off the round nut holding the drawer assembly. Rotate the drawer assembly and pull it out. Inspect the nozzle for soot and replace. The size and angle of spray will be marked on the side of it. Inspect and adjust your electrodes according to the manufactures specifications of the burner (not the boiler). Put everything back together and test fire it. If your boiler has not been cleaned in the last year, change the filter at the oil tank. If it continues to lock-out, change the primary control (usually honeywell 8184G) with a newer version.

Boiler makes twitching sound and doenst stay on


If the boiler uses oil (#2 fuel diesel); there are several factors that could cause this problem:
* Lack of oil due to clogged oil filter or restricted oil line.
* Cad resistance greater than 1500 ohms.
* Defective Primary control.
* Shoot accumulated on the retention head.
* En pinching flame in combustion chamber.
* Collapsed combustion chamber into firing range.
* There are other reason not listed here.
* Some problems require expensive testing equipment to make an accurate diagnosis.
* Get in touch with an oil burner technician with several years of experience. I have a license to practice in the state of Massachusetts. My number is 978-5443783

Burner propblem


have you tried to wipe off the fire eye on the unit if it has one? If it's dirty too then it will not see the flame and not let the unit come on correctly. Good Luck and have a Happy New Year.

Burner will not fire


Dear muttandjeff,
I do not know if you machine is single or three phase. But whatever, one simple thing is to check that you have the right rotation. If the rotation is good, then fuel can be pumped. Now there must be a sensor that switches on with water flow. No water....no fire. If there is water passing, then the sensor is stuck and showing that there is no flow. The thermostat also opens a solinoid valve in most machines of this type. If solinoid valve is faulty....fuel will not come out. If this is a diesel boiler...check gap of electrodes and condotion of fuel nozzel. One last thing, is something I found in a machine of a friend of mine. I found everything correct....but then I found that the fuel was totaly mixed with water. So, that you have correct fuel, is also important.
