What it is
The Worcester Bosch venturi, rated at 24 kW and supplied under part number 8738902776, is the mixing component that draws gas and air together in the correct proportion ahead of the burner. It sits in the combustion air path of the appliance and its internal profile governs the pressure drop that drives the mixing process. The part is specific to the Worcester Greenstar 1000 Series 24 C NG platform.
