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.
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.

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.
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 aer 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.

General information
1.7 WATER TREATMENT
Treating the supply water allows you to prevent problems and
maintain the functionality and eciency of the generator over time.
e purpose of this treatment is to eliminate or signicantly 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, 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 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 eciently, 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 (buer eect).
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.

3.4 POSITIONING THE HEATING
CONTROL UNIT
Special attention must be paid to local standards and regulations
regarding heating control units, especially the minimum distances
that must be observed.
Installation must be comply with the requirements contained in the
most recent standards and legislation regarding heating control units,
heating system installation and hot water production, ventilation, ues
suitable for condensation boiler combustion product exhaust, and any
other applicable regulation.
A
e boiler can be placed on a at platform that is suciently sturdy
in size, in plan, no smaller than the boiler measurements and with a
minimum height of at least 100 mm so that the trap for condensate
drainage can be installed. Alternatively, a trap can be built from this
platform, next to the boiler, at a depth of 100 mm so that the trap can
be placed in it (Parag. 3.16).
When installation is complete the boiler should be perfectly horizontal
and rmly stable (to reduce vibrations and noise).
