General information
1.7 WATER TREATMENT
Treating the supply water allows you to prevent
problems and maintain the functionality and
eciency of the generator over time.
e ideal pH value of the water in the central heating
system must be:
VALUE MIN MAX
PH 6,5 8
HARDNESS (°fr) 9 15
To minimise corrosion, it is essential to use a corrosion
inhibitor. In order for it to work eciently, the metal
surfaces must be clean.
ATTENTION!
Any damage caused to the boiler, due to the formation
of build-up or corrosive water, will not be covered by
the warranty.
ATTENTION!
e models only equipped with central heating are
NOT suitable for hot water production for human
consumption (M.D. 174/2004).
1.8 BOILER FROST PROTECTION
Activated by default
is protection only cuts in when the electric and gas supply are present.
If the electric or gas supply are disconnected and 11 (SM) detects a
temperature of between 2 and 5°C when the supply is restored, the
appliance responds as indicated in the table below, in pos.2.
Antifreeze products with an inhibitor for central heat-
ing systems (specic for multimetal) can be used to
ensure ecient protection of the central heating against
freezing.
Do not use antifreeze products for car engines since
these can damage the water gaskets.

e request for heat can be generated by the HSCP thermoregulation/
manager or alternatively by the BCM (Boiler controller).
The management logic envisions simultaneous operation of the
maximum number of heat elements, so as to always obtain the
maximum eciency. Since it guarantees the maximum exchange area
based on the delivered power. e elements are made to operate so as
to equally divide the operating time.
e hot water that is produced is pushed by the pump located on the
return of the primary ring to the ow of the hydraulic separator. From
here a second pump (system - see suggested diagrams) will distribute to
the various utilities. From the system, return the cooled water is taken
in by the pump on the return, through the hydraulic separator, to start
the cycle towards the generator again.

e boiler pump must have head that can ensure circulator ow rates
according to the circuit’s ∆t.
The pumps must be determined by the installer or
designer based on the data for the boiler and system.
2.4.2 DETERMINING THE PRIMARY CIRCUIT PUMP OR BOILER PUMP
NOTE:
It is always advisable to set up a hydraulic compensator
between the boiler circuit and the system circuit. It
becomes ESSENTIAL if the system requires greater
ow rates than the maximum allowed by the boiler,
i.e. ∆t below 15K.
EXAMPLE:
For a T 20K, of an ARES 250 Tec the maximum
required ow rate is 10514 l/h.
From the head loss graph it is possible to deduce that
the pump must ensure a head of at least 1.6 m/H2O.

3.1 GENERAL RECOMMENDATIONS
ATTENTION!
is boiler must only be employed for its explicitly
intended use. Any other use must be considered
improper and therefore dangerous.
is boiler is used to heat water to below boiling
temperature in atmospheric pressure.
ATTENTION!
e appliances are designed to be installed inside
buildings only in suitable technical compartments,
and also outdoors in a completely open place.
Before connecting the boiler, have professionally
authorised company:
a) Accurately washing all of the pipes in the system
to remove any residues or sediments could stop
the boiler form running eciently, even in terms
of health and hygiene.
b) Making sure the boiler is set up to operate with the
available type of fuel. e type of fuel is stated on the
packaging and technical characteristics plate.
c) Make sure that the chimney/ue has an adequate
draught, that it is not choked, and that there are no
other exhausts for other appliances, unless the ue
is designed for multiple utilities, in accordance with
standard specications and requirements in force.
Only once this check has been carried out can the
tting between boiler and chimney/ue be set up.
ATTENTION!
In rooms with aggressive vapour or dust, the
appliance must operate independently of the air in
the room of installation!
ATTENTION!
e appliance must be installed by an authorised
company possessing professional-technical
qualications in accordance with the law, who, under
his/her own responsibility, enforces the observance of
regulations according to the rules of good practice.
ATTENTION!
Assemble the appliance in observance of the minimum
required distances for installation and maintenance.
