What it is

The hydraulic delaying device is a Riello component (part number 3007870) used within Riello oil burner assemblies. It controls the hydraulic delay in the burner's start sequence, governing the timing of the ignition and oil delivery stages. It is classed as an oil boiler spare.

Signs this part needs replacing

  • Burner start sequence timing drifts, with ignition occurring later or earlier than expected
  • Burner locks out intermittently during start-up
  • Delayed or rough ignition on start
  • Inconsistent combustion behaviour across successive start cycles
  • Visible damage, contamination or sticking at the delay device

Before you order

  • Confirm the burner model and type code against the fitment list above
  • Check the existing part number on the component matches 3007870
  • Verify the burner is a Riello Gulliver RG4S or RG5S unit before ordering
  • Inspect the surrounding hydraulic circuit for contamination that may have caused the failure
