What it is

The Vokera 20089999 is a smoke analysis cap, listed in parts catalogues as a plug and nut. It seals the flue gas sampling point on Vokera gas boilers, allowing combustion readings to be taken and the test point to be closed off again afterwards. It sits within the screws, nuts, bolts and clips category of Vokera gas boiler spares.

Signs this part needs replacing

  • The cap is missing or was not refitted after a service
  • The sealing face is damaged, distorted or cross-threaded
  • Flue gas can be detected escaping from the sampling point
  • The cap is corroded or seized and will not seal correctly
  • Combustion readings are unstable or inconsistent when the point is closed

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number 20089999 against the existing cap or the manufacturer's parts list
  • Inspect the sampling point thread for damage before fitting a new cap
