What it is

The Vaillant 178823 nozzle conversion set is a service item supplied under the 18X D 2.80 designation. It is listed by Vaillant under part number 178823 and is used when a burner nozzle arrangement has to be converted or reset to the specified configuration. It is a consumable rather than an appliance-specific spare, so it is not tied to a single boiler or cylinder model.

Before you order

  • Confirm the designation 18X D 2.80 matches the nozzle configuration required for the appliance being worked on.
  • Check the burner or appliance documentation for the nozzle size and type called for before converting.
  • Verify the Vaillant part number 178823 against the reference in your own parts listing to avoid ordering the wrong set.
  • Nozzle work should be carried out by a competent heating engineer, with combustion readings checked and recorded after any conversion.
