to entrap all the impurities in the gas or in
gas main pipes.
To prevent malfunctioning of the valve, or in
certain cases even to cut out the safety
device with which the valve is equipped,
install an adequate filter on the gas pipe.
2.4 SYSTEM FILLING
Filling of the boiler and the system is done
by the charge load faucet (fig. 23/a).
The charge pressure, with the system cold,
must be between 1 and 1.5 bar. During
system filling you are recommended to
keep the main switch turned OFF. Filling
must be done slowly so as to allow any air
bubbles to be bled off through the air valves.
2.4. 1 System draining
To drain the system, turn off the boiler and
IMPORTANT:
- The insertion of each additional 90°
bend with a diameter of 60/100
reduces the available section by 1.5
meters.
- The insertion of each additional 90°
bend with a diameter of 80/125
reduces the available section by 2
meters.
- Each additional 45° curve installed
reduces the available length by 1.0
metres.
- During assembly it is important to
make sure that the kit with axial
pipes. (1) is positioned horizontally.
NOTE: Before connecting accesso-
ries, it is always advisable to lubrica-
te the internal part of the gaskets
with silicon products. Avoid using oils
and greases.
