7.2. Connecting the boiler to the heating installation.
Such connection must be performed by a technician / service shop
authorized for such operations.
When the boiler is connected to a heating system, it is mandatory to install a 4 bar
relief valve and expansion vessel. No shut-off fittings may be installed between the
relief valve, expansion vessel and boiler.
It is mandatory to install a three-way valve (Laddomat or similar) or a
four-way mixing valve which to ensure that the temperature of the
heating medium fed into the boiler from the heating installation is at
least 65°С.
