What it is

The Sime 6174808 is a burner flange gasket for Sime gas boilers. It seals the joint between the premix burner and the burner flange, preventing combustion gases from escaping at that connection. It is used across the Sime Dewy and Planet Dewy ranges.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket material
  • Soot deposits or discolouration around the burner flange joint
  • Signs of leakage at the burner-to-flange connection
  • The gasket is damaged or deformed when the burner is removed for servicing

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check the existing gasket against part number 6174808
  • Inspect the burner flange faces for damage or pitting before refitting
