experienced during replacement of components.
4. After replacing any component on the boiler, close tap, close the drain valve and open all system isolating valves (re-pressurise
as appropriate by re-connecting the filling loop, refer to Frame 30) before proceeding to check operation of the boiler.
5. Disconnect filling loop. Refer to Frame 30.
