1.1.10. SYSTEM FILLING
WARNING
For system filling use only clean tap water.
WARNING
If the system is filled by adding ethylene
glycol-type chemical agents you have to install on
the loading system a hydraulic trip unit in order to
separate the heating circuit from the domestic circuit.
Before powering up the boiler, fill the system as
follows:
1.
slightly loosen the cap of the circulator jolly
valve (1-fig. 1) to release the air from the
system;
2.
slightly loosen the cap of the jolly valve placed
on the top of the condensing block (fig. 3) to
release the air form the top of the system;
3.
open the feeding tap "R" (fig. 2);
4.
release all the air;
5.
use pressure gauge "M" (fig. 2) to make sure
that the system pressure reaches 1.2 bar (fig.
4);
6.
after performing this operation, make sure
that the loading tap "R" (fig. 2) is properly
closed.
