- Check that the hydro-block assembly fitted to the appliance is the type this kit serves, as hydro-block variants differ across Worcester Bosch models.
- Cross-check the boiler model and GC number against Worcester Bosch technical literature if the required O rings are not clearly identified.
- Have the boiler's installation and service documentation to hand so the correct sealing points can be identified before dismantling.
