What it is

The Vaillant gas section is a component of the gas train on the Atmocraft VK 1654/9 boiler, sitting within the appliance's gas valve assembly. It forms part of the path taken by gas from the supply connection into the combustion chamber, and its condition affects how reliably the boiler lights and burns. It is supplied as a Vaillant part under number 295437.

Signs this part needs replacing

  • A smell of gas or a detected leak around the gas section or its joints.
  • Visible corrosion, staining or debris on the gas section body.
  • The boiler fails to light, locks out, or the flame is unstable.
  • Combustion readings fall outside the expected range on a flue gas analysis.
  • The gas valve assembly will not hold pressure during a tightness test.

Before you order

  • Confirm the appliance model is the Atmocraft VK 1654/9 and check the data badge.
  • Check the existing part number against the manufacturer's parts list for your appliance.
  • Work on the gas train must be carried out by a Gas Safe registered engineer.
  • Isolate the gas and electrical supply before any inspection or replacement.
