What it is

The Riello 3003847 is an ignition transformer for Riello RS range oil burners. It provides the high-voltage spark required to ignite the oil/air mixture at the burner. This transformer is listed for Riello burner spares and oil boiler applications.

Signs this part needs replacing

  • Burner fails to ignite or locks out on start-up.
  • No spark at the ignition electrodes.
  • Intermittent ignition or repeated lockouts.
  • Visible damage, arcing, or burning at the transformer.
  • Burner runs but ignition is unreliable.

Before you order

  • Check the burner model and code against the fitment list.
  • Confirm the existing transformer is marked 3003847 or matches the RS range application.
  • Check the burner type and code, as multiple RS variants use different components.
  • If unsure, consult the manufacturer's parts list for the burner.
