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
heating 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.

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.

Technical characteristics and dimensions
e pump is not an integral part of the boiler. It is advisable to choose a
pump with a ow rate and head of approximately 2/3 of its typical curve.
ARES TEC 550 ErP
Maximum ow rate in l/h (Δt = 15 K) 30.404
Nominal requested ow rate in l/h (Δt = 20 K) 22.804
ARES TEC 900 ErP
Maximum ow rate in l/h (Δt = 15 K) 48.647
Nominal requested ow rate in l/h (Δt = 20 K) 36.487
ARES TEC 440 ErP
Maximum ow rate in l/h (Δt = 15 K) 24.326
Nominal requested ow rate in l/h (Δt = 20 K) 18.243
ARES TEC 770 ErP
Maximum ow rate in l/h (Δt = 15 K) 42.570
Nominal requested ow rate in l/h (Δt = 20 K) 31.926
ARES TEC 660 ErP
Maximum ow rate in l/h (Δt = 15 K) 36.487
Nominal requested ow rate in l/h (Δt = 20 K) 27.365
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
EXAMPLE:
For a T 20K, of an ARES Tec ErP 900 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.
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.

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!
