8. Unscrew the circulator cap (2-fig.10) to release
any air bubbles and close it to prevent water
leakage;
9. Open the air relief valves of the radiators and
check the air removal process. When the
water starts to leak close the radiators air
relief valves.
10. If after performing these operations you
observe a decrease of the water pressure
inside the system, open once again the loading
tap “R” until the pressure gauge indicates the
value of 1.2 bar (fig. 13)
1.1.13. FILLING THE CONDENSATE
COLLECTION SIPHON
Before starting the boiler you have to fill the
condensate collection siphon in order to avoid flue
back up through the siphon.
Fill the condensate collection siphon as follows
(see fig. 14):
› Unscrew the “T” cap from the siphon, fill three
quarters of the the siphon with water and screw
the “T” cap back in;
› Connect the dedicated flexible condensate
draining tube “P” to a waste disposal system.
The condensate can be drained directly in the
sewer system by inserting an easily serviceable
siphon.
WARNING
After the first months of boiler operation,
it is recommended to clean the condensate trap, to
eliminate possible deposits coming from the first
flow of the condensate inside the boiler technical
components. These deposits could cause a
malfunctioning of the trap.
