How often should a Riello oil burner be serviced?

Riello oil burners require annual servicing by an OFTEC registered heating technician. This is essential for reliability and to avoid excessive fuel consumption.

How do I bleed a Riello oil burner after running out of fuel?

After refilling with oil, allow the fuel to settle for up to an hour, then locate the bleed valve on the burner (usually an allen screw on the side). Place a suitable container underneath to catch any fuel spillage - oil is flammable and spillages must be cleaned immediately. Loosen the screw to release trapped air, then press the reset button once air stops escaping and oil begins to flow. If the burner fails to start after two or three attempts, contact an OFTEC registered heating technician.

What should I check if my Riello oil burner keeps locking out?

Repeated lockouts typically indicate one of four issues: fuel starvation (check oil level and filters), a faulty solenoid valve, a dirty photocell, or a control box fault. If lockouts occur after a few days of normal running, fuel supply problems are most likely. If they occur 10-15 minutes after ignition, the solenoid may be failing when hot. Contact an OFTEC registered heating technician for diagnosis.

How do I access the Riello burner diagnostics to identify a fault?

Wait at least 10 seconds after lockout, then press and hold the reset button for more than 3 seconds. The red LED will begin flashing a sequence of pulses, repeated at 3-second intervals. Count the flashes to identify the fault code.

What causes a Riello oil burner to fail to ignite?

Common causes include air in the fuel line after running out of oil, a clogged nozzle, dirty or misaligned electrodes, a weak ignition transformer, or clogged fuel filters. Nozzles should never be cleaned - they must be replaced annually. Contact an OFTEC registered heating technician if the burner fails to ignite after two or three reset attempts.
