PLUMBING INFORMATION
Primaries must be 28MM minimum. Flow and return pipework must be 22MM minimum.
The key feature of this layout is the injector tee, which allows primary gravity circulation to occur when
the pump is not running and induced gravity flow to occur when the pump is running.
To reduce the necessity of running four pipes from the boiler, it is possible to fit the injector tee at first
floor level and then to fit a flow and return only to the boiler connected diagonally as shown.
In case of electrical failure it is essential to allow at least 25% - 30% of the boiler output, to be
available as a form of gravity heat leak. This can be achieved by fitting radiators teed off the primary
circuit, as illustrated in the diagram
