What it is
The Vaillant 0020017311 throttle jet set is a flue restrictor assembly for Vaillant Mag CAR appliances. It fits into the flue path to restrict flue gas flow so the appliance operates within its designed combustion figures. The part is supplied as a set by Vaillant.
Signs this part needs replacing

- Sooting or staining around the flue terminal or air intake
- Flue draught readings that no longer match the appliance's expected figures
