What it is

The Glow-worm gas manifold (part 2000801855) carries the gas supply to the burner and distributes it evenly across 17 injectors. It is configured for G20 natural gas and is used on Glow-worm GW 30CI and GW 30SI appliances. The manifold sits between the gas valve and the burner assembly, so correct injector alignment and sealing are essential to safe combustion.

Signs this part needs replacing

  • Uneven flame pattern across the burner, with some injectors not lighting
  • Sooting, yellow tipping or lifting flames at the burner
  • A smell of gas around the manifold or injector joints
  • Combustion readings drifting outside the expected range for the appliance
  • Visible damage, corrosion or blockage at the manifold or injector ports

Before you order

  • Confirm the appliance model and GC number against the manufacturer's parts list
  • Check the existing manifold is a 17 injector G20 version before ordering
  • Work on the gas-carrying components must be carried out by a Gas Safe registered engineer
  • Isolate and purge the gas supply in line with current regulations before removal
