INSTRUCTIONS FOR USE
AND MAINTENANCE
2.1 CLEANING AND MAINTENANCE.
Important:
the heating plants must undergo
periodical maintenance (regarding this, see in
the section dedicated to the technician, relative
to “yearly control and maintenance of the ap-
pliance”) and regular checks of energy efficiency
in compliance with national, regional or local
provisions in force.
This ensures that the optimal safety, performance
and operation characteristics of the boiler remain
unchanged over time.
We recommend stipulating a yearly cleaning
and maintenance contract with your zone
technician.
2.2 AERATION AND VENTILATION OF
THE INSTALLATION ROOMS.
Consult the “Aeration and ventilation of instal-
lation rooms” chapter in this book.
2.3 GENERAL WARNINGS.
Use of the boiler by unskilled persons or children
is strictly prohibited.
For safety purposes, check that the concentric
air intake/flue exhaust terminal (if fitted), is
not blocked.
If temporary shutdown of the boiler is required,
proceed as follows:
a) drain the water system if anti-freeze is not
used;
b) shut-off all electrical, water and gas sup-
plies.
N.B.:
in the case of maintenance interventions of
the boiler that lead to the closure or one or both
system cut-off cocks (34 Fig. 1-30), the boiler
must be switched-off.
In the case of work or maintenance to structures
located in the vicinity of ducting or devices for
flue extraction and relative accessories, switch off
the appliance and on completion of operations
ensure that a qualified technician checks efficien-
cy of the ducting or other devices.
Never clean the appliance or connected parts
with easily flammable substances.
Never leave containers or flammable substances
in the same environment as the appliance.

Attention:
the use of components that employ
electrical power requires some fundamental
rules to be observed:
- do not touch the appliance with wet or moist
parts of the body; do not touch when barefo-
ot;
- do not pull electric cables;
- the appliance power cable must not be repla-
ced by the user;
- in the event of damage to the cable, switch
off the appliance and contact exclusively
qualified staff for replacement;
- if the appliance is not to be used for a certain
period, disconnect the main power switch.

Boiler ignition.
Before ignition, make sure that
the system is full of water, controlling that the
manometer (3) indicates a base value at which
the system has been designed and calculated and
however not less than 0.5 bar.
- Open the gas cock upstream from the boiler.
- Turn the main switch (1) taking it to the ON
position.
The boiler is supplied with a self-regulation
board, accessible only after the hatch is opened,
which is made up from a display of 4 characters
and 6 keys. These keys can be used to regulate the
boiler as in the presence of traditional selectors
and knobs.
Each key has the following function:
RESET Manual restore of any boiler block
MODE Display menu selection key
STEP
Selection of the parameter to di-
splay or modify
STORE Key for confirmation of data and
memorisation
+
Increasing the value set
-
Decreasing the value set
In the functioning phase the 4 character display
indicates the functioning mode (using the first
two characters on the left) and the boiler flow
temperature (the other two characters on the
right).
For example, if these values are
read on the display it means that
the appliance is functioning in
CH mode with flow temperature
of 60°C.
