real estate used as a dwelling, does not have to be added together.
The presence of threaded joints on the gas supply line determines
the need for the room where the appliance is installed to be
ventilated (UNI
7129). It is therefore advisable to equip the room with ventilation
openings in order to ensure a change of air, with an outlet grille in
the area of natural accumulation of any gas leaks.
WARNING
Where the temperature of the room where the water
heater is installed can drop over 4 ° C it is advisable to insert an
electric heater kit (see chapter 'ANTIFREEZE PROTECTION').

1.1.8. HYDRAULIC CONNECTION
DANGER
Make sure that the system piping
water supply are not used as an earth connection for the electrical
system. They are absolutely not suitable for this use.
WARNING
During connection operations
of the appliance to the water connections avoid excessive twisting
and in any case recovery operations from any off-axis that could
damage the hydraulic fittings with consequent risk of leaks,
malfunctioning or premature wear.
WARNING
To avoid vibrations and noise in the
systems do not use pipes with reduced diameters or small radius
elbows and significant reductions in the passage sections.
WARNING
Connect the safety drains of the
water heater with a discharge funnel. The manufacturer is not
responsible for any flooding due to the opening of the safety valve
in the event of system overpressure.
WARNING
In order to prevent encrustations
limestone and damage to the sanitary exchanger, the sanitary
supply water must be treated in accordance with current
legislation. According to the DPR 59/09 it is mandatory to treat
water over 15 ° French for sanitary water, by means of chemical
treatment (according to UNI 8065) of conditioning for power
< 100 kW or softening for powers> 100 kW. It is also necessary to
install a safety filter to protect the system.
WARNING
The pressure of the incoming cold water
must be between 0.5 and 6 bar. In the presence of higher
pressures, it is essential to install a pressure reducer upstream of
the water heater.

1.1.9. ANTIFREEZE PROTECTION
The electric heater kit is an anti-freeze system that comes into
operation when the domestic hot water probe detects a
temperature of 4 ° C, heating the exchanger pipes until reaching a
temperature of 8 ° C.
ATTENTION
The system operates even if the
display shows “OFF”, provided that the water heater is powered
electrically.
Whenever there is a danger of freezing and an optional electric
heater kit is not installed on the water heater, it is necessary to
empty the sanitary system (see chapter 'EMPTYING THE
SANITARY SYSTEM').

1.1.10. GAS CONNECTION 1.1.11. ELECTRICAL CONNECTION
DANGER
To connect the gas connection of the
appliance to the supply pipe, use a gasket of suitable size and
material. The use of hemp, Teflon tape and the like is prohibited.
DANGER
The electrical safety of the appliance is
reached only when it is correctly connected to an effective
grounding system, performed as required by current safety
standards (CEI 64-8 and 64-9 Electrical Part). This fundamental
safety requirement must be checked. If in doubt, request an
accurate check of the electrical system by professionally qualified
personnel, since the manufacturer is not responsible for any
damage caused by the lack of earthing of the system.
BEFORE CONNECTING THE GAS, CHECK THE FOLLOWING:
›The gas supply line must comply
the standards and regulations in force (UNI 7129);
›The piping must have an adequate section
according to the required capacity and its length;
›Check that the electrical system is adequate
to the maximum power absorbed by the appliance
indicated on the data plate.
›The piping must be equipped with all
safety and control devices prescribed by current regulations;
›Make sure that the section of the system cables
is suitable for the maximum power absorbed by the appliance
and in any case not less than 1 mm 2.
›Check the internal tightness and
external of the gas inlet system;
›The appliance works with alternating current a
230 V and 50 Hz.
› check through the data plate of the appliance (located on the
inside of the front casing) that the appliance is set up for
operation with the type of gas available in the network. If they
differ, it is necessary to intervene on the appliance to adapt to
another type of gas (see chapter GAS TRANSFORMATION);
WARNING
Make sure the phase connection
and neutral respect the wiring diagram (see chapter WIRING
DIAGRAM).
WARNING
›Check that the supply pressure
of the gas is between the values shown on the data plate.
