What it is

The Riello 3005793 is a diffuser disc with an MTN 0, four-leg pattern, used in Riello oil burners. It forms part of the combustion head assembly, where it shapes airflow around the nozzle to support stable flame formation. It is a service component for RDB and R40 series burners.

Signs this part needs replacing

  • Heavy soot or carbon build-up on the disc surface
  • Distorted, cracked or eroded legs
  • Unstable, pulsating or noisy flame
  • Poor combustion readings that persist after nozzle and pump checks

Before you order

  • Confirm your burner model and code against the fitment list
  • Check the existing disc's leg pattern and MTN marking
  • Verify part number 3005793 on the burner's parts list
