and property for which the manufacturer will not be held liable.
Changes to parts connected to the appliance
Do not make changes to the following elements:
- to the boiler
- to the gas, air, water and power supply lines
- to the ue pipe, safety valve and exhaust pipe
- to the constructive elements that aect the operational safety of the appliance
General information
Attention!
To tighten or loosen the screw-attached ttings, use suitable wrenches only.
Improper use and/or unsuitable tools can cause damage (for ex. water and gas leaks).
ATTENTION!
Instructions for appliances running on propane gas
Make sure that the gas tank has been deaerated prior to installing the appliance.
For a thorough deaeration of the tank contact the liquid gas supplier and in any case authorised sta, in accordance with the law.
Ignition problems can arise if the tank is not thoroughly deaerated.
In this case contact the liquid gas tank supplier.
Smell of gas
In case of the smell of gas observe the following safety instructions:
- do not use electric switches
- do not smoke
- do not use the telephone
- shut o the gas cut-o valve
- aerate the room where the gas leak occurred
- notify the gas supply company or a company specialised in the installation and maintenance of heating systems.
Explosive and easily ammable substances
Do not use or deposit explosive or easily ammable materials (for ex. petrol, paints, paper) in the room where the appliance is
installed.
ATTENTION!
e heat unit must be installed so as to avoid, under the envisioned operating conditions, the liquid contained in it from freezing
and avoid exposing the command and control parts to temperatures below -15°C and over +40°C.
e heat unit must be protected from climatic/environmental variations by:
- insulating the hydraulic and condensation exhaust pipes
- adopting specic antifreeze products in the hydraulic system.

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 technician, who is in charge of enforcing observance of all local and/or
national laws published in the Ocial 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
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 specic regulations
and qualied 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.
Attention!
If the new boiler is installed in an old system without
having washed the system, as specied 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.
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.005480/000STD.005480/000

1.7 WATER TREATMENT
Treating the feed water allows you to prevent problems and maintain the functionality and eciency 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 eciently, 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.
General information
ATTENTION!
e models only equipped with central heating are
not suitable for hot water production for human
consumption.

1.8 GENERAL RECOMMENDATIONS
e instruction handbook is an integral and essential part of the product
and must be kept safe by the individual in charge of the system.
Read the warnings contained in the handbook carefully, as they provide
important instructions regarding installation, user and maintenance
safety.
Keep the handbook safe for future consultation.
e appliance must be installed and maintained in accordance with
regulations in force, pursuant to the instructions of the manufacturer, the state of the art and by authorised and qualied personnel,
in accordance with the law.
Professionally qualied personnel means sta with specic technical
skills in the sector of heating system parts for civil use, hot water
production for domestic use and maintenance. is personnel must
have the authorisations required by legislation in force.
Incorrect installation or poor maintenance can cause injury to persons
and animals and damage to objects, for which the manufacturer is
not liable.
Before carrying out any cleaning or maintenance operations, cut the
appliance o from the power mains by acting on the switch on the
system and/or using the cut-o devices.
Any repairs to the products must be carried out by authorised Immergas personnel only, using original spare parts only. Failure to observe
the above can jeopardise the safety of the appliance and will void the
warranty.
e guarantee the eciency of the appliance and its correct operation it
is essential for authorised personnel to carry out annual maintenance.
If the appliance is put out of use for downtime, any part that is susceptible to posing a potential source of danger must be made safe.
Before re-commissioning an appliance that has been put out of use,
proceed to washing the domestic hot water production system, making
water ow through it for the amount of time required to change the
water completely.
If the appliance is sold or transferred to another owner or if the owner
moves, leaving the appliance behind, always ensure the handbook
accompanies the appliance so that it may be consulted by the new
owner and/or installer.
All appliances with optionals or kits (including electric) must only use
original spare parts.
e appliance must only be employed for its expressly foreseen use.
Any other use must be considered improper and therefore dangerous.
Do not obstruct the intake/exhaust pipe terminals.
In case of a fault and/or poor operation of the appliance, switch it o,
and do not attempt in any way to repair it or intervene directly. Only
contact personnel that has been authorised in accordance with the law.
