What it is
The Vaillant 178824 is a nozzle conversion set marked 18X D 1,65, supplied for LPG boiler applications. It forms part of the nozzle range used on Vaillant Atmocraft VK appliances, where the nozzle governs the gas flow delivered to the burner. Fitting the correct nozzle set is what allows the appliance to run on the fuel type it is being converted to.
Signs this part needs replacing
- The appliance is being converted to LPG and the existing nozzle set is not rated for the new fuel.
- Combustion readings fall outside the expected range and cannot be corrected by adjustment alone.
- Sooting, staining or unstable flame characteristics at the burner.
- The existing nozzle is damaged, blocked or has been drilled or modified.
- The nozzle marking does not match the fuel type the appliance is set up to run on.
Before you order
- Confirm your appliance model against the fit list above before ordering.
- Check the nozzle marking currently fitted and compare it with 18X D 1,65.
- Verify the appliance is intended for the fuel type this conversion set supports.
- Follow the manufacturer's conversion and commissioning instructions, including any required gas pressure checks.
