Frequently Asked Questions (FAQs)

1. What does the Worcester Greenstar CDI Gas Valve SIT 848 87161165150 do?

The gas valve regulates the flow of gas from the gas supply to the burner. It works with the PCB, fan, and burner to provide the correct gas-to-air mixture for safe, efficient combustion.

2. Which boilers are compatible with part number 87161165150?

This gas valve fits selected Worcester Greenstar CDI, Greenstar CDI Classic, Greenstar FS CDI, and Greenstar Highflow CDI boilers. Always confirm the part number, boiler model, and GC number before ordering.

3. Can a faulty gas valve cause ignition lockout?

Yes. If the gas valve fails to open or regulate gas correctly, the boiler may fail to ignite. This often causes repeated ignition attempts before the boiler enters a lockout condition.

4. Does the SIT 848 gas valve require commissioning after installation?

Yes. A Gas Safe registered engineer must commission the boiler after fitting the gas valve. They should check combustion values with a calibrated flue gas analyser and adjust the valve if required.

Yes. Incorrect gas flow affects combustion efficiency. This can increase gas consumption, reduce heat output, and prevent the boiler from operating at its designed efficiency.
