1. Take off the red cover which is held on by a screw.

2. Use an allan key to loosen the screw facing you.

3. Turn on boiler. The boiler will draw the oil through and bubbles of air will escape through the screw you have loosened.

4. When it is just oil coming through the cracks around the screw, re-tighten the screw and turn on again.

SOURCE: riello burner will not pump oil to nozzel to burn.

Revisit the photocell:
1. Check if you connected the socket end, into the two pins properly, as it is possible to miss a pin.
2. Try to borrow a working photocell or use yours in another burner to make a determination.

SOURCE: 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.

SOURCE: Riello 40 F5 oil burner, on boiler, intermittently running

with a forced draught burner the fan motor would be checked via a pressure switch. if the pressure switch is not set correctly or the fan is too weak the contacts will not be made in the switch and the burner will lockout. if the damper is not open enough when the fan runs then the air supply will be too small for the switch to make. check to see if you have a capacitor on the fan windings if this is faulty then the fan will fail intermittently.

If the moror just humes then locks out, more that likely the capacitor (small white cylinder like object below control box), get yourself a 5uf capacitor, 2 wires, jobe done!!

Riello f5 oil motor will not start


Is your electric air shutter opening? That causes power to come on. Here's a link.

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.

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!

I have a riello 40 burner it fires for 2 seconds then cuts out what could be the problem


If it actually fires up and you have a flame for 2 seconds and then it shuts off, I'd bet that the photo cell is either dirty or has failed. If it is dirty, it suggests that the burner has been neglected for some time and probably is in desperate need of a tune up. The photo cell is located under the ignition transformer and is aimed into the combustion chamber to see the light created by the flame from the burning oil.

If it is clean, the photocell has likely failed and will need to be replaced. If it still runs the same way after photocell replacement, it is probably related to the primary controller or one of the other safety devices. Is this a forced hot air or hot water system?

The motor should spin when the boiler is switched on. One end of the motor spins the fan the other end works the pump. The control box then starts the transformer that starts a spark. The control box then opens up the oil. The boiler should then light if any of the above or the boiler does not light, the boiler will go to lockout.
From what you say the motor is not spinning, thus it could be the motor or more like the pump.

YOU SHOULD NOT PLAY WITHE THE PUMP

If the wrong setting is made it could 1 burn out the back of your boiler 2 go to soot and the boilers in an hour would be filled up and become a fire risk. 3 not start at all if the setting is too low it is a fine line to get it to work and needs the right tools.

Replace the nozzle, don't try and clean it. After the burner runs a few seconds, do you have to reset the control (red button) before it will start again? Does it sound like there is a pulsation in the flame when it starts or it is running out of oil? You may have a bad ignition control. Start with the small stuff, nozzle, strainer filter, oil tank filter and then work to the more complicated.
