This appliance produces hot water, therefore it must be connect-
ed to a heating system and/or a domestic hot water mains, com-
patible with its performance and output.
In case of water leakage, close the water supply and contact the
Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply
and switch off the electrical supply main switch. If there is a risk
of frost, drain the boiler.
From time to time check that the operating pressure of the hy-
draulic system does not decrease under 1 bar.
In case of failure and/or malfunctioning, deactivate the appli-
ance, and do not try to repair or intervene directly on it.
Appliance maintenance must be carried out at least once a year:
scheduling it with the Technical Assistance Service will avoid
wasting time and money.
At the end of its life, the product should be not be disposed of
as solid urban waste, but rather it should be handed over to a
differentiated waste collection centre.

Do not use the appliance in any manner other than its intended
purpose.
It is dangerous to touch the appliance with wet or damp body
parts and/or in bare feet.
Under no circumstances should you cover the intake grids, dis-
sipation grids and ventilation vents in the installation room with
cloths, paper or any other material.
Do not activate electrical switches, telephone or any other object
that causes sparks if there is a smell of gas. Ventilate the room
by opening doors and windows and close the gas central tap.
Do not lean any object on the boiler.
Do not perform any cleaning operation until the appliance has
been disconnected from the main power supply.
Do not access the inside of the boiler. Any work on the boiler

instructions on how to use it safely and are made aware by a
responsible person of the dangers its use might entail. Children
must not play with the appliance. It is the user's responsibility to
clean and maintain the appliance. Children should never clean
or maintain it unless they are given supervision.
It is forbidden to obstruct the condensate outlet.
For better use, remember that:
- regular external cleaning with soapy water not only improves the
appearance but also protects panelling against corrosion, extending
its life cycle;
- if the wall-hung boiler is enclosed in wall-mounted cabinets, leave at
least 5cm for ventilation and maintenance;
- the installation of an ambient thermostat will ensure greater comfort,
more rational heat use, and energy savings; the boiler can also be
connected to a programming clock in order to manage ignition and
switch-off during the day or week.
2A APPLIANCE IGNITION
At the same time, if it is necessary to put the appliance in service again,
carefully follow the described operations.
To start-up the boiler it is necessary to carry out the following opera-

- open the gas tap present in the system to allow fuel flow
- set the ambient thermostat at the required temperature (~20°C)
- turn the function selector (3 - fig. 3) to the required position:
Winter: turn the function selector (3 - fi g. 3) in the area marked with
+ and - (fi g. 24b) to obtain DHW and heating. In the case of a heat
request, the boiler will switch on and the digital display will show the
temperature of the heating water, the heating mode icon and the fl ame
icon (fi g. 25). In the case of a request for domestic hot water, the dis-
play (2 - fi g. 3) will show the temperature of the domestic water, the
DHW mode icon and the fl ame icon (fi g. 26).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with the
symbol (fi g. 27) clockwise in the area marked with + and -.

This function keeps the water in the domestic hot water exchanger hot,
to reduce standby times when a request is made.
The display indicates the outlet temperature of the heating water or the
domestic hot water based upon the request in progress. During burner
ignition following a pre-heating request, the display shows the fl ashing
symbol and the fl ame icon (fi g. 30).
To deactivate the pre-heating function, rotate the domestic hot water
