Prior to ignition, make sure that the appliance is set up to operate
with the gas available; this can be checked by the wording on the
packaging and by the adhesive label indicating the type of gas.
Establish the piping diameter according to the standards in force.
Before installing the appliance, it is recommended that you blow the gas
piping so as to remove any processing waste. Connect the appliance to
the internal system gas pipe and insert a tap upstream of the appliance to

appliance
- that the appliance is powered by the type of fuel for which it has been
set up
- that the fuel supply pressure is within the values shown on the label
- that the fuel supply system has been sized for the input necessary for
es provided for by the standards in force.
b
In case of prolonged user absence from the appliance, shut off the
main appliance gas supply tap.
b
Do not use the gas tubes as an earthing system for electrical ap-
pliances.

3.7 Water connection

Connect the appliance to the water mains and insert a water isolation
Looking at the appliance head on, the cold water inlet is to the right and
the hot water outlet to the left.
b
The domestic hot water circuit does not need a safety valve, but
make sure that the pressure of water main does not exceed 6 bar.
In case of doubts, install a pressure reducer.
b
Ensure that the water system pipes are not used as earthing for
your electrical or telephone system. They are in no way designed
for this purpose. Using them in this way may cause serious damage
to the pipes and the appliance itself in a short space of time.
b

ti-freeze systems; when there is a risk of frost (temperatures lower
in a partially protected place it is always necessary to use anti-freeze
systems to suitably protect the appliance from the risk of freezing.
Adequately protect the taps and the hydraulic connecting pipes of
the installation.
The appliance comes as standard with an auto-

matic anti-freeze system that protects the domestic hot water circuit
from freezing in the event of ambient temperatures down to -10°C.
b
An electrical supply is required in order to take advantage of this
protection, implemented with electrically powered resistors with
heating wire. this means that any blackout or disconnection of the
power supply will deactivate the protection. The anti-freeze protec-
tion is active also with the appliance in stand-by.
b
The anti-freeze protects the water heater's domestic hot water cir-
cuit up to the hydraulic connections (domestic hot water inlet and
tect the hydraulic connection pipes and taps. In any event it is nec-
essary to adequately protect the taps and the hydraulic connecting
pipes of the installation.

3.9 Emptying the water heater

- To empty the water heater:
- turn off the main water supply tap
- open all the water taps
- make sure that the taps at the lowest points of the system allow the
water heater to be completely emptied.

3.10 Gas conversion

-
the appliance already installed.
b
personnel pursuant to Min. Decree 37 of 2008, the provisions in
UNI 7129 and 7131 must also be respected.
The appliance can be converted from one type of gas to another using
- Methane conversion kit
- LPG conversion kit
Proceed as follows to perform the conversion:
- switch off the electrical supply
- remove in succession the casing, the air distribution box cover and the
combustion chamber cover
- disconnect the glowplug cable connection
- remove the lower cable grommet from its seat on the air distribution box
-
- fully unscrew the top nut of the gas valve train
