One of the possible installation processes is shown in Figure 8.
-
The safety valve must be placed close to the boiler and must be set to a maximum pressure
of 3 bar (boiler is tested to 4 bar). The connecting line of the safety valve must be as short as
possible and must not have the possibility of closing. In this connecting line also there must
not be any single valve or any other fitting.
-
Closed expansion vessel is placed close to the boiler and has a short security line. The
volume of the expansion vessel is calculated by the folloving formula:
V = 0,07xVwater, (l), where Vwater is volume of the water in entire system.
