Safety valve (to protect against excess pressure
in the system)
The safety valve

is a safety device for protecting
against overpressure in the water circuit of the hea-
ting system.
Functioning: The valve opens when the system pres-
sure exceeds 3 bar. Water/steam are discharged into
an open drain via a blow-off line, which avoids con-
sequential damage to the heating system com-
ponents. The safety valve is closed during normal
operation.
The safety valve is not included and must be installed
by the customer.
