General information
1.5 REGULATIONS FOR INSTALLATION
e appliance must be installed in accordance with the instructions
contained in this manual.
Installation must be carried out by an authorised professional tech-
nician, who is in charge of enforcing observance of all local and/or
national laws published in the Ocial Gazette, as well as all appli-
cable technical regulations.
It is necessary to observe the standards, regulations and requirements
for installation provided below, constituting a rough and non-exhaus-
tive list, in order to follow the evolution of the "state of the art". We
would like to underline that updating the list of standards is the
responsibility of the technicians authorised to carry out installation.
Also observe the standards regarding the heating control unit, con-
struction regulations and requirements on combustion heating in the
country of installation.
e appliance must be installed, commissioned and subject to mainte-
nance in accordance with the current "state of the art". is also applies
to the hydraulic system, the ue exhaust system, the installation room
and the electrical system.
Failure to observe the above regulations will void the warranty
Attention!
If the new boiler is installed in an old system without
having washed the system, as specied in the aforesaid
paragraph, any residues in the circuit may accumulate
in the generator, causing it to clog.
If ARES PRO is being installed on a new system , it is advisable to wash
it thoroughly, using products that are suitable for the entire system,
and install a Y-strainer with two cut-o valves on the return pipe to
the boiler, so that it can be cleaned as needed.
is lter will protect the boiler from sediments coming from the
heating system.
In both cases it is necessary to keep the head losses localised in the
primary circuit, for the correct sizing of the pump.
1.6 INSTALLATION
When the appliance is installed on existing systems, make sure that:
- e ue is suitable for condensation appliances, for the temperatures
of the combustion products, calculated and built in accordance with
regulations in force. at is it a straight as possible, water-tight and
insulated and does not have any obstructions or constrictions.
- e ue is equipped with an attachment to evacuate the condensation.
- e heating control unit is equipped with a pipe for the evacuation
of the condensation produced by the boiler.
- e electrical system is built in accordance with specic regulations
and qualied technical personnel.
- e ow rate, head and direction of ow of the circulation pumps is
appropriate.
- e fuel feed line and any existing tanks are set up in accordance with
regulations in force.
- e expansion vessels ensure complete absorption of the dilation of
the uid contained in the system.
- Slurry and build-up have been cleaned out of the system.
Important!
National law requires the water to be treated in new
installations or renovation of heating systems and
replacement of heat generators.
If ARES PRO is being installed on existing Systems:
If it is possible to schedule the replacement, it is necessary to wash
the system preventively, with alkaline dispersants. Washing must be
carried out four weeks prior to replacement, with a system operating
between 35°C - 40°C. It is always recommended to install a lter,
however, it is obligatory above 350 kW.
STD.005480/001

General information
1.7 WATER TREATMENT
Treating the feed water allows you to prevent prob-
lems 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

3INSTRUCTIONS FOR INSTALLATION
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.
Before connecting the boiler, have professionally
qualied personnel:
a) Accurately washing all of the pipes in the system to
remove any residues or sediments that could stop
the boiler from running eciently.
b) Making sure the boiler is set up to operate with
the available type of fuel.
This 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!
If the installation area has aggressive/corrosive pow-
ders and/or vapours, the device must be adequately
protected and must operate independently from the
air provided in the room.
IMPORTANT!
Assemble the appliance in observance of the mini-
mum required distances for installation and main-
tenance.
e boiler must be connected to a central heating
system and/or domestic hot water circuit, in com-
pliance with its performance and capacity.
