Why oil flows into Oilon Burner combustion chamber during burning period?
If the Oilon Burner has oil flowing into the combustion chamber during the burning period, it means that the nozzle valve and main oil valve, or the nozzle valve and non-return valve, are not closing properly. You should clean, repair, or replace them.
Why Oilon Burner motor does not start and lockout occurs?
If the Oilon Burner motor does not start and a lockout occurs with symbol 11, several issues could be the cause: * There might be a break in the main circuit; repair the break. * The motor overload relay might be triggered; check and reset or change the relay. * A fuse might be triggered; reset or change the fuse. * The motor contactor might be faulty; change it. * The motor itself might be faulty; change it. * There could be a break in the motor control circuit; repair the break. * The control unit might be faulty; change the control unit. * The return pressure might be too high, triggering the pressure switch; examine and isolate the fault.
What to do if Oilon RP-250 M Burner lockout during shutdown?
If the Oilon Burner experiences a lockout during shutdown (Symbol ?), this could be due to: * A faulty flame detector; in this case, you should change the flame detector. * A faulty control unit; change the control unit. * Incorrect flame signal due to extraneous light; prevent extraneous light from reaching the flame detector. * Valves do not close; clean, repair or replace them.
What to do if Oilon RP-250 M Burner motor starts, ignition is operational, after a short period of time a lockout occurs?
If the Oilon Burner motor starts, the ignition is operational, but after a short period of time a lockout occurs (Symbol 11), consider the following: * The solenoid valve may not be functioning; change the valve. * The coil on the solenoid valve may be faulty; change the coil. * The cable may be damaged; change the cable. * The control unit may be faulty; change the control unit.
Why Oilon Burner motor starts, control voltage from control unit to ignition transformer is switched on, but ignition does not happen?
If the Oilon Burner motor starts, but the control voltage from the control unit to the ignition transformer is switched on, ignition does not happen, and after a short time a lockout occurs (Symbol 11), it could be due to: * Dirty or worn ignition electrodes, or a cracked insulator; clean or change them. * Ignition electrodes being too far apart; adjust them according to the instructions. * A damaged ignition cable; change the cables. * A faulty ignition transformer; change the transformer.
Why Oilon RP-250 M nozzle valve does not open?
If the Oilon Burner's nozzle valve does not open, it could be due to: * The nozzle needle not opening; change the nozzle. * The nozzle valve piston being stuck; change the piston or the O-ring. * A clogged throttle plug; clean the plug.
Why Oilon RP-250 M has no spray from nozzle?
If the Oilon Burner has no spray from the nozzle, it could be due to: * Inadequate oil atomizing pressure; see 'pump adjustments'. * A faulty nozzle O-ring; change the O-ring.
Why Oilon RP-250 M Burner makes loud mechanical noise?
If the Oilon Burner is making a loud mechanical noise, it could be due to: * The pump cavitating or insufficient inlet pressure to the burner; tighten joints, clean the filter, and check and adjust to the burner pressure. * The inlet oil temperature being too low; raise the inlet oil temperature. * Inlet oil pipings connected incorrectly; check joints.
Why is there a constant oil leak from Oilon RP-250 M Burner nozzle valve when the nozzle is closed?
If there is a constant oil leak from the Oilon Burner's nozzle valve when the nozzle is closed, it indicates a leak in either the non-return valve or the main solenoid valve. You should change the valve.
Why Oilon RP-250 M Burner supplies no oil or atomizing pressure is too low?
If the Oilon Burner supplies no oil, or the atomizing pressure is too low, consider the following possible causes: * A dirty filter; clean or change the filter. * A leaking suction line of the transfer pump; fix the leaks. * Decreased pump capacity, or a worn or faulty pump; change the pump.
