What it is

The Riello 3005787 is a flange gasket for Riello oil burners, used with flange 5786. It seals the joint between the burner flange and the appliance mounting face, preventing oil seepage and air ingress at that connection. It sits within the Riello oil boiler spares range of O-rings, washers and gaskets.

Signs this part needs replacing

  • Oil weeping or staining around the burner flange joint
  • Gasket hardened, cracked or flattened across the sealing face
  • Combustion smell or an unstable flame caused by air being drawn in at the flange
  • Gasket torn or deformed when the flange is removed

Before you order

  • Match your burner model and code against the list above
  • Confirm the burner is fitted with flange 5786
  • Check the flange and mounting faces are clean and undamaged before fitting the new gasket
