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 a professionally authorised company,
who is in charge of enforcing observance of all local and/or national
laws published in the Ocial Gazette, as well as all applicable
technical regulations.
It is necessary to observe the standards, regulations and requirements
for installation provided below, constituting a rough and non-exhaustive
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,
construction regulations and requirements on combustion heating in
the country of installation.
e appliance must be installed, commissioned and subject to
maintenance 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 flushed the system, as indicated in the
previous paragraph, any residues present in the
circuit could accumulate in the generator,
generating clogging.
Otherwise, if ARES Pro is being installed on a new system:
it is advisable to wash it thoroughly in any case, 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 by professionally authorised company.
- 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!
e National Standard prescribes water treatment
in case of new installation 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. e installation of a lter is always recommended
and, above 350 kW, it is necessary (ref. National Standard).

3INSTRUCTIONS FOR INSTALLATION
3.1 GENERAL WARNINGS
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
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,
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!
If aggressive / corrosive powders and / or vapors are
present in the installation room, the appliance must
be adequately protected and must be able to operate
independently of the room air.
ATTENTION!
Assemble the appliance in observance of the mi-
nimum required distances for installation and
maintenance.
e boiler must be connected to a heating system
and / or a domestic hot water distribution network,
compatible with its performance and power.
