What it is

The Ferroli 39842400 is a combustion chamber gasket measuring 10mm x 5mm, used as a case seal on the combustion chamber of compatible Ferroli gas boilers. It seals the joint between the combustion chamber and its casing, preventing flue gases from escaping into the appliance compartment. The gasket is a service item and should be renewed whenever the chamber is opened.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket material
  • Soot or staining around the combustion chamber case joint
  • Combustion readings drifting outside the expected range on flue gas analysis
  • The gasket is disturbed or compressed whenever the chamber cover is removed
  • Signs of flue gas leakage at the chamber seal

Before you order

  • Confirm your boiler model against the fitment list above
  • Check the existing gasket dimensions and section profile match 10mm x 5mm
  • Inspect the mating surfaces for corrosion or pitting before refitting
  • Isolate the gas and electrical supply before opening the combustion chamber
