What it is

The Saunier Duval gas manifold G20 is a 14-injector burner bar and pipe assembly. It distributes gas to the burner injectors on Saunier Duval Themaclassic PLUS F24E boilers. The manifold is a key part of the combustion circuit.

Signs this part needs replacing

  • Boiler fails to ignite or repeatedly locks out
  • Uneven or weak flame across the burner
  • Yellow or sooty flame instead of a crisp blue flame
  • Gas smell or visible leakage around the manifold
  • Popping, whistling or rumbling noises from the burner area

Before you order

  • Confirm your boiler is a Saunier Duval Themaclassic PLUS F24E.
  • Check the GC number 47-920-37 on the appliance data badge.
  • Verify the existing part number S1016400 or the earlier code 1016400.
  • Installation must be carried out by a Gas Safe registered engineer.
