What it is

The Vokera gas diaphragm, part number 10020265, is a gas-side component used in the Vokera Mynute HE family of condensing boilers. It is listed against the NG injector assembly and forms part of the gas train, where it regulates gas flow through the valve. It is a serviceable item that degrades with age and is replaced when gas pressure control becomes erratic.

Signs this part needs replacing

  • Burner pressure that will not hold steady or drifts from the commissioning figure
  • Rough or unstable flame, with the boiler failing to modulate cleanly
  • Delayed, weak or repeated ignition attempts
  • Whistling or chattering from the gas valve during firing
  • Visible hardening, cracking or perishing of the diaphragm material on inspection

Before you order

  • Confirm the boiler model against the rating plate, as several Mynute HE variants share this part
  • Check whether the appliance is natural gas or LPG, as both are listed against this component
  • Verify the part number on the existing component before removal
  • Isolate the gas supply and follow the manufacturer's instructions for gas-carrying parts
