The G 3/4” cap installs on the free boiler return fitting (if the expansion vessel is not installed on this fitting).
The kit includes boiler delivery and return shut-off valves which enable the system to be worked on without having to empty out the
entire heating system, as well as allowing any single boiler to be isolated from the cascade.
