WARNINGS AND SAFETY

Our boilers are built in our plants and checked down to the small-
est detail in order to protect users and fitters from injury. After
working on the product, qualified personnel must check the elec-
trical wiring, in particular the stripped part of conductors, which
must not stick out from the terminal board, avoiding possible con-
tact with live parts of such conductor.
This instruction manual, together with the user manual, are in-
tegral parts of the product: make sure they are always kept with
the appliance, even if it is transferred to another owner or user,
or moved to another heating system. In the event of loss or dam-
age, please contact your local Technical Assistance Centre for a
new copy.
Boiler installation and any other assistance and maintenance
operations must be carried out by qualified personnel according
to the provisions of the legislation in force.
Boiler maintenance must be carried out at least once a year.
This should be booked in advance with the Technical Assistance
Centre.
The installer must instruct the user about the operation of the
appliance and about essential safety regulations.
This boiler must only be used for the application it was designed
for. The manufacturer declines all contractual and non-contrac-
tual liability for injury to persons or animals or damage to proper-
ty deriving from errors made during installation, adjustment and
maintenance and from improper use.
This appliance should not be operated by children younger than

differentiated waste collection centre.
During installation, inform the user that:
- in the event of water leaks, the water supply must be shut off and the
Technical Assistance Centre must be contacted immediately
- the operating pressure of the hydraulic system must be checked reg-
ularly to ensure it is higher than 1 bar. If necessary, restore the cor-
rect pressure level as explained in the paragraph "Filling the system"
- if the boiler has not been used for a long time, it is recommended that
the Technical Assistance Centre performs the following operations:
- turn the main appliance switch and the main system switch to "off"
- turn off the fuel and water taps of the heating system
- drain the heating and domestic hot water circuits if there is any risk
of them freezing
- boiler maintenance must be carried out at least once a year; this
should be booked in advance with the Technical Assistance Centre.

For safety, always remember that:
it is dangerous to activate electrical devices or appliances (such
as switches, home appliances, etc.) if you smell gas or fumes.
In the event of gas leaks, ventilate the room by opening doors
and windows, turn off the main gas tap and request the prompt
intervention of the Technical Assistance Centre
do not touch the boiler while barefoot, or if parts of your body are
wet or damp
before carrying out any cleaning operations, turn the function se-
lector to OFF/RESET so that the display shows "- -", and discon-
nect the boiler from the electricity supply by turning off the bipolar
system switch
do not modify safety and adjustment devices without the manu-
facturer's permission and relative instructions
do not pull, disconnect or twist the electric cables coming out
of the boiler, even when it is disconnected from the main power
supply
avoid covering or reducing the size of the ventilation openings in
the installation room
