Why does a Riello gas burner need to stop at least once every 24 hours?

Riello gas burners are approved for intermittent operation, meaning they must stop at least once every 24 hours to allow the electrical control box to perform efficiency checks at start-up.

How often should the oil nozzle be replaced on a Riello burner?

The oil nozzle should be checked and replaced annually as part of routine maintenance. Nozzles should never be cleaned - always replace them.

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.

What is the recommended ignition electrode gap for Riello gas burners?

The ignition electrode gap for Riello gas burners should be maintained at 2-3mm for optimal spark performance.

How often should the oil filter be replaced on a Riello system?

The external oil filter should be replaced at least once a year. The filter container should be thoroughly cleaned before installing the new filter.
