What it is

The Vaillant 0020240267 is a gas control valve used on Vaillant EcoTec VUW combi boilers. It regulates the supply of gas to the burner and modulates input in line with the boiler's demand signal. It is listed for the 286/7-2 and 346/7-2 appliance families, including EcoTec Sustain variants.

Signs this part needs replacing

  • Boiler fails to fire, or repeatedly locks out during an ignition attempt
  • Flame is unstable, drops out, or fails to hold during a demand for heat
  • Boiler runs at a fixed rate with no modulation, or cycles more than expected
  • Gas valve body shows signs of leakage or there is a smell of gas — isolate the supply and call a Gas Safe registered engineer
  • Fault codes relating to the gas valve or flame supervision are logged on the appliance

Before you order

  • Confirm the boiler model against the appliance data badge before ordering
  • Check whether the appliance is a 286/7-2 or 346/7-2 variant
  • Compare the part number on the existing valve where it is visible
  • Gas-carrying components must be fitted and commissioned by a Gas Safe registered engineer
