What it is

The Vokera 10021253 is a gas valve for the Mynute E series of gas boilers. It is a SIT 840 Sigma valve, SIT reference 0.840.030, which regulates the gas supply to the burner in response to demand from the boiler controls.

Signs this part needs replacing

  • Boiler fails to fire or ignite on a call for heat
  • Repeated lockouts or flame failure faults
  • Flame drops out shortly after ignition
  • Poor or erratic modulation, with the burner unable to hold a steady rate
  • Gas valve body shows signs of leakage, or the solenoid fails to operate

Before you order

  • Confirm the boiler model and GC number against the fitment list.
  • Check the SIT reference on the existing valve matches 0.840.030.
  • On the Mynute 20E, establish whether the appliance is an early or later model.
  • Gas valve replacement is a gas safety-critical task and must be carried out by a Gas Safe registered engineer.
