Domestic hot water and central heating circuits must be completed with expansion vessels of adequate capacity and suitable,
correctly-sized safety valves. The discharge of safety valves and appliances must be connected to a suitable collection and dis-
posal system (see Catalogue for compatible accessories).

The choice of system components and the method of their installation are left up to the heating engineer installing the system.
Installers must use their expertise to ensure proper installation and functioning in conformity to all applicable legislation.
