What it is

This is a SIT tandem gas valve, part 0.830.010, used on Glow-worm Economy, Economy Plus and Ultimate FF boilers from serial number 3037. It regulates gas flow to the burner as part of the boiler's ignition and flame control sequence. For earlier models, refer to the Honeywell section.

Signs this part needs replacing

  • Boiler fails to ignite or locks out with no flame
  • No gas pressure at the burner during a demand
  • Intermittent ignition, especially when hot or after cycling
  • Unstable flame or poor modulation
  • Gas smell around the valve; isolate the supply and call a Gas Safe registered engineer

Before you order

  • Confirm the boiler model and serial number; this valve applies from serial number 3037
  • Check whether the boiler is an earlier version covered in the Honeywell section
  • Compare the existing valve marking with SIT tandem 0.830.010
  • Work must be carried out by a Gas Safe registered engineer
