What it is

The Glow-worm 0020018823 is a gas section kit for the G20 (natural gas) gas valve assembly rated at 35kW. It forms the gas-carrying section of the valve on Glow-worm GW 38CXI, Ultracom 38CXI and Xtramax HE boilers, controlling gas flow to the burner. The kit supersedes the earlier code 802172.

Signs this part needs replacing

  • The boiler fails to ignite or the burner will not light despite a call for heat.
  • Repeated flame-failure or ignition lockouts that clear only after a reset.
  • No gas is delivered to the burner when the valve is energised.
  • Whistling, humming or clicking from the gas valve area during operation.
  • A smell of gas around the valve body or its connections.

Before you order

  • Confirm the boiler model and GC number against the fitment list above.
  • Check the appliance is set up for G20 natural gas, as this section is rated for G20 at 35kW.
  • Check whether the existing valve carries the earlier code 802172, which this kit replaces.
  • Work on the gas section must be carried out by a Gas Safe registered engineer.
