A certified safety valve not exceeding 2.5 bar
must be installed in the heating system. The
safety valve sizing should be to current regula-
tions. Do not install other valves between the
safety valve and boiler. The water return temper-
ature must not fall below 60 °C to prevent the
build up of condensate inside the boiler.
