What it is

The gas valve assembly is a Glow-worm component that regulates the flow of gas to the burner on Compact and Micracom combi boilers. It controls gas delivery in line with the appliance's demand signal, so the burner receives the correct volume of gas for ignition and modulation. It is supplied under Glow-worm part number 0010028747.

Signs this part needs replacing

  • The boiler fails to fire or ignite, with no gas reaching the burner
  • Repeated lockouts or ignition faults that return after resetting
  • The burner flame is weak, unstable or will not modulate correctly
  • The appliance runs erratically, with fluctuating or poor heat output
  • A smell of gas around the appliance, or the gas valve fails a tightness test

Before you order

  • Confirm the boiler model against the fitment list above, as the Compact and Micracom ranges use different variants
  • Check the part number on the existing gas valve matches 0010028747 before ordering
  • Rule out ignition, flame detection and PCB faults first, as these can produce similar symptoms
  • Work on the gas valve must be carried out by a Gas Safe registered engineer
