2.14 Filling the heating system and eliminating air

In the case of a new installation or replacement of the boiler, it is
necessary to clean the heating system beforehand. To ensure the
device works well, after every cleaning intervention remember to
top up the additives and/or chemical treatments (e.g. anti-freeze
liquids, filming agents, etc.) and check the parameters are within
the values indicated in the tables.

For the POWER EVO-X boiler, there must be a system filling line,
preferably connected to the return line.
Before emptying or filling the system, disconnect the appliance
from the electricity supply. For changes of direction, use a T-shaped
fitting with an inspection plug that allows the piping to be easily
cleaned periodically.
Always make sure that after cleaning the inspection plugs are her-
metically sealed with the relative gasket.
ƒ Before filling the system, make sure the air outlet plug of the
venting valve in the boiler is open (loosened)
ƒ Use the pressure gauge to check the pressure reaches the val-
ue envisaged for the system (1.5-2.0 bar)
ƒ Reconnecting the electricity supply; the boiler will run the auto-
matic venting cycle
NOTA: every time the boiler is electrically powered, the automatic
venting cycle is run (it lasts 6 min) .
NOTE: if there is a water alarm (E040, E041 or E042), the venting
cycle cannot be carried out.
ƒ If the system pressure is lower than 1 bar following the
venting cycle, fill the system again.
