in the sequence shown in Diagram 1. Ensure the valves are installed in the correct
orientation by reference to the direction of flow arrows marked on them. The
Expansion Vessel should be supported by its own wall bracket (supplied),
do not
rely on the pipework alone to support it.
4.2

compression fittings. Do not use solder joints as this will damage the heater and
may prevent servicing under warranty.

conventional taps can be served, however, individual site demands should be
considered when choosing capacity and the number of outlets to be served.
4.4

supply to the heater.
4.5
A drain cock must be fitted below the heater in the inlet pipework. It must be sited
between the heater and the Check Valve (see Diagram 1). 11).
