Riello Burner control RMG88.62C2 3013073

The Riello 3013073 is a burner control box, model RMG88.62C2, designed for use in industrial and commercial burners. It operates on a supply voltage of 220–240 V and has a safety time of 3 seconds. This control manages the ignition sequence, including pre-purge, ignition transformer energization, and fuel valve operation, while monitoring flame presence via an ionisation electrode or UV/IR detector. If flame is not detected within the safety time, it locks out and requires manual reset. It is manufactured for Riello and is also listed under code LMO88.620C2RL.

When selecting a replacement control box of this type, verify that the supply voltage, safety time, and flame detection method match the original unit. The wiring base or plug pattern must be compatible, and the control's series and type designation should be cross-referenced with the existing markings. Ensure that the pre-purge time and inputs from air and gas pressure switches are correctly configured for the burner. Controls of different series are generally not interchangeable, so exact matching is critical for safety.

Typical failures of this kind include lockout due to flame detection issues, which may be caused by a faulty ionisation electrode or UV/IR detector. The equipment may fail to start or shut down during operation, often indicated by a reset button popping out. Check the flame sensor, wiring connections, and supply voltage to diagnose the problem. If the control repeatedly locks out, it may indicate a deeper issue with the burner's combustion or ventilation system.
