USER GUIDE
1a GENERAL WARNINGS AND SAFETY
The instruction manual is an integral part of the product and it must there-
fore be kept carefully and must accompany the appliance; if the manual
is lost or damaged, another copy must be requested from the Technical

b
The safety and automatic adjustment devices must not be modified,
during the system life cycle, by the manufacturer or supplier.
b
This appliance produces hot water, therefore it must be connected to
a heating system and/or a domestic hot water mains, compatible with
its performance and output.
b
In case of water leakage, close the water supply and contact the
Technical Assistance Service immediately.
b
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.
b
From time to time check that the operating pressure of the hydraulic
system does not go below 1 bar.
b
In case of failure and/or malfunctioning, deactivate the appliance, and
do not try to repair or operate directly on it.
b
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.
Boiler use requires strict observation of some basic safety rules:
a
Do not use the appliance in any manner other than its intended
purpose.
a
It is dangerous to touch the appliance with wet or damp body parts
and/or when barefoot.
a
Under no circumstances cover the intake grids, dissipation grids and
ventilation vents in the installation room with cloths, paper or any
other material.
a
Do not use 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 central gas tap.
a
Do not place anything in the boiler.
a
Do not perform any cleaning operation if the appliance is not
disconnected from the mains power supply.
a
Do not cover or reduce ventilation opening of the room where the
generator is installed.
a
Do not leave containers and inflammable products in the installation
room.
a
Do not attempt to repair the appliance in case of failure and/or
malfunctioning.
a
It is dangerous to pull or twist the electric cables.
a
Do not access the inside of the boiler. Any work on the boiler should
be carried out by the Technical Assistance Centre or by professionally
qualified personnel.
a
Do not carry out operations on sealed elements.
For better use, remember that:
- periodic external cleaning with soapy water not only improves its appear-
ance but also preserves panelling from corrosion, extending its life cycle;
- if the wall-mounted boiler is enclosed in a hanging unit, leave at least 5
cm for ventilation and maintenance;
- installation of a room thermostat will greatly improve comfort, a more ra-
tional use of the heat and energy saving; the boiler can also be connected
to a programmable timer in order to control the switching on and off of the
appliance during the day or week.
2a SWITCHING ON THE APPLIANCE
Every time the appliance is powered up, a series of data is shown on the
display including the flue gas sensor meter reading (-C- XX) (see paragraph
4a - fault A09); the automatic purge cycle then starts, lasting around 2 min -
utes. During this phase the symbol is shown on the monitor (fig. 25).
To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the flow of fuel
- set the room thermostat to the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fig. 27) within the area marked
+ and -, the boiler provides domestic hot water and heating. If there is a heat
request, the boiler switches on. The digital monitor indicates the heating
water temperature, the icon to indicate heating and the flame icon (fig. 29).
If there is a domestic hot water request, the boiler switches on.
The digital display shows the hot water system temperature, the icon to
indicate the hot water supply and the flame icon (fig. 30).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 27) within the area and -.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery temperature
is automatically chosen by the system which rapidly adjusts ambient tem-
perature to the changes in external temperature.
To increase or decrease the temperature with respect to the value automa-
tically calculated by the electronic board, turn the heating water selector
clockwise to increase and anticlockwise to decrease.
Adjustment settings range from comfort levels - 5 to + 5 which are indicated
on the digital display when the knob is turned.
Summer mode: turning the selector to the summer mode symbol (fig.
28) activates the traditional
domestic hot water only
function.
If there is a domestic hot water request, the boiler switches on. The digital
monitor indicates the domestic hot water temperature, the icon to indicate
the hot water supply and the flame icon (fig. 30).
