What it is
The Worcester Bosch Venturi 30 kW is a combustion air/gas venturi supplied under part number 8738902777. It is fitted within the air-gas circuit of the Worcester Greenstar 1000 Series boiler, where the venturi creates the pressure drop that draws gas into the combustion air stream in the correct proportion. It is a serviceable component, so it is replaced as a single item rather than as part of a larger assembly.
Signs this part needs replacing
- Boiler locks out or fails to establish a stable flame
- Combustion readings drift outside the expected range for the appliance
- Whistling or unusual induction noise from the air-gas circuit
- Visible contamination, blockage or damage to the venturi throat or tappings
- Repeated ignition faults after the gas and air supplies have been checked
Before you order
- Confirm the appliance is a Greenstar 1000 Series Gr1000W 30 C NG
- Check the 30 kW rating matches the boiler being worked on
- Confirm the gas type is natural gas
- Compare the part number on the existing venturi against 8738902777
