16.5 FILLING THE SYSTEM SATURNO
To fill the system, the stove can be equipped with an end piece (optional) with a non-return valve (D) for manual filling of the
heating system (if the optional is not installed, the filling tap on the main boiler will be used). During this operation, any air in the
system is released from the automatic vent valve located under the top.
To ensure the valve vents, it is advisable to loosen the grey cap one turn and leave the red cap blocked (see figure). Set the filling
pressure of the system
WHEN COLD
to
1 bar
(100 kPa). During operation, if the system pressure drops (due to evaporation of
dissolved gases in the water) to values lower than the minimum indicated above, the user must use the filling tap to bring the
pressure back up to its normal pressure.
To ensure correct stove operation, the maximum pressure in the system WHEN HOT must not exceed 1.5 bar (150 kPa).
To monitor the system pressure, the terminal (optional) is equipped with a pressure gauge (M).
Upon completion of this operation, always close the tap.
Fit the system with a 2 bar safety valve connected to an accessible outlet.
It is normal for there to be noises and gurgling until all the air in the system has been expelled.

16.6 WATER CHARACTERISTICS
The characteristics of the water used to fill the system are very important to prevent the build-up of mineral salts and the forma-
tion of incrustations along the pipes, in the boiler and in the heat exchangers.
Therefore, please ASK YOUR PLUMBER FOR HIS ADVICE CONCERNING:
Hardness of water circulating in the system, to prevent problems of incrustation and limescale, especially in
the domestic water heat exchanger. (> 25° French).
Installation of a water softener (if water hardness exceeds 25° French).
Filling the system with treated water (demineralised).
Possibly providing an anti-condensation circuit.
Installation of hydraulic shock absorbers to prevent water hammering along the fittings and pipes.
If you have very extensive systems (with a large amount of water) or which require frequent refilling, the installation of water
softening systems.
It should be remembered that incrustations drastically reduce performance due to their extremely low thermal
conductivity.
