water siDe connection
The connection of the boiler to the heating network (delivery and return) must be made with at least the following pipe sections:

28 mm
lnk 20 evo
28 mm
lnk 30 evo
35 mm
lnk 40 evo

lime, corrosion and rust sludge interfere with the operation of the heating system.
The filling water must meet the requirements of european, national and local regulations on the treatment of technical water (e.g. desalination,
softening, sludge removal) to avoid resulting damage.
The system can be filled and emptied only when it is cold.
When filling it, it is necessary to check the line or boiler pressure using a pressure gauge. It is advisable to fill it using a permanently installed
filling system to minimise the oxygen content of the system.
aTTenTIon: even the smallest amounts of oxygen combined with the high water temperature in heating systems inevitably
lead to corrosion.
for correct filling, bleed the system both during and at the end of the filling operations.
When emptying it, make sure that the system is cold and that the water pressure in the heating circuit is suitable for the ambient pressure by
manually activating the boiler safety unit. This prevents dangerous situations while emptying it.
