What it is

The Vaillant 0010042298 is a gas valve assembly supplied for liquid gas operation. It forms part of the gas train on the appliance, controlling the supply of gas to the burner under the boiler's electronic modulation. It is listed by Vaillant for use across a defined group of Ecotec models.

Signs this part needs replacing

  • The boiler fails to ignite or repeatedly goes to lockout with no flame established.
  • Flame is unstable, drops out shortly after ignition, or the burner will not modulate smoothly.
  • Gas valve body shows signs of leakage, staining, or a detectable gas odour around the assembly.
  • Whistling, buzzing, or irregular clicking from the valve area during a demand for heat.
  • Fault codes relating to flame detection or gas valve operation appear on the appliance display.

Before you order

  • Confirm the appliance model and GC number against the fitment list above, as the same appliance range can use different gas train components.
  • Check the existing valve's part number and fuel type marking before ordering, since liquid gas and natural gas variants are not interchangeable.
  • Installation and any work on the gas train must be carried out by a Gas Safe registered engineer.
  • Verify the appliance's installation and commissioning documentation for any model-specific requirements.
