1.5 REGULATIONS FOR INSTALLATION
ARES Tec is a gas category II2H3P heating unit.
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.
The 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 has been replaced in an old system
without having preventively washed it as described
above, do not wash the system, as any residues of
the product in the circuit may ll the generator with
residues aer replacement.
It is advisable to contact a company specialised in
water treatment.
Otherwise, if ARES Tec 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.
If ARES Tec 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.

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 purpose of this treatment is to eliminate or signicantly reduce
problems that can be outlined as:
build-up
corrosion
sediments
biological growth (mould, fungus, algae, bacteria, etc.).
e chemical analysis of the water provides a lot of information on the
state and "health" of the system.
e pH level is a numerical indication of the acidity or alkalinity of
a solution.
e pH scale goes from 0 to 14, where 7 corresponds to neutral.
Values below 7 indicate acidity, values above 7 indicate alkalinity.
e ideal pH value in heating systems with aluminium boilers is
between 6.5 and 8,5, with a hardness of 15°F.
Water in a system with a pH value outside of this range considerably
accelerates the destruction of the protective oxide layer which forms
naturally inside the aluminium bodies, and would not occur naturally: if
the pH level is lower than 6,5 it contains acid, if it is above 8 the water is
alkaline, either due to an alkaline treatment (for example phosphates or
glycols operating as antifreeze) or in some cases the natural generation
of alkalis in the system.
Vice versa, if the pH value is between 6.5 and 8, the aluminium surfaces
in the body are passivated and protected from further corrosive attacks.
To minimise corrosion, it is essential to use a corrosion inhibitor.
In order for it to work eciently, however, the metal surfaces must
be clean.
The best inhibitors on the market also contain an aluminium
protection system that stabilises the pH levels of the ller water,
preventing sudden changes (buer eect).
It is advisable to systematically check (at least twice a year) the
pH value of the water in the system. In order to do so a chemical
laboratory analysis is not required, but a simple check using a
analysis "kit" contained in a carry cases, easily available on the
market.
It will therefore be necessary to set up the devices shown in the gure
in the heating system.
THE COUPLING MUST BE SET UP ON THE
RETURN PIPE TO THE PRIMARY CIRCUIT
DOWNSTREAM OF THE PUMP.
All of the precautions required to avoid the formation and localisation of
oxygen in the water of the system. For this reason the plastic pipes used
in the under-oor heating systems must not be permeable to oxygen.
Make sure that any anti-freeze products are compatible with aliminium
and any other parts and materials in the system.
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!
These appliances are designed and developed to
transfer heat to a heat carrying uid possessing the
characteristics described here, they are not suitable to
directly heat water intended for human consumption.

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.
ATTENTION!
These appliances are designed exclusively for
installation inside suitable technical compartments.
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.
e boiler must be connected to a heating system
compatibly with its specications and power.
