What it is

The SIT Tandem gas valve is a gas control component used on Glow-worm Hideaway floor-standing boiler models. It regulates the flow of gas to the burner in response to demand from the appliance controls. This valve carries the Glow-worm part number 2000801590 and the SIT reference 0.830.033.

Signs this part needs replacing

  • The burner fails to light or lights only intermittently on a call for heat
  • The boiler locks out repeatedly, with the fault returning after reset
  • Flame is weak, unstable or drops out shortly after ignition
  • Gas can be heard or smelled passing when there is no demand
  • The valve does not respond to the appliance controls, leaving the burner permanently off or permanently on

Before you order

  • Confirm your appliance model against the fitment list above, including the BFF or CFF suffix
  • Check the part number on the existing valve matches 2000801590 or the earlier code 801590
  • Gas valve replacement is gas work and must be carried out by a competent, registered engineer
  • Check the valve body, connections and any associated leads for condition before fitting
