INSTRUCTIONS FOR USE
AND MAINTENANCE
2.1 CLEANING AND MAINTENANCE.
Attention: the heating systems must undergo
periodical maintenance (regarding this, see
the section dedicated to the maintenance
engineer, relating to “yearly appliance check
and maintenance”) and regular energy efficiency
checks 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.
2.2 VENTILATION OF THE ROOMS.
In the room in which the boiler is installed it
is necessary that at least as much air flows as
that requested for by normal combustion of the
gas and ventilation of the room. The provisions
relative to ventilation, the flue ducts, chimneys
and caps are stated in Par. 1.6, 1.7 and 1.8. If
in doubt regarding correct ventilation, refer to
professional, qualified staff.
2.3 GENERAL WARNINGS.
Never expose the wall-mounted boiler to direct
vapours from a cooking surface.
Use of the boiler by unskilled persons or children
is strictly prohibited.
If temporary shutdown of the boiler is required,
proceed as follows:
a) drain the heating system if anti-freeze is not
used;
b) shut-off all electrical, water and gas supplies.
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 efficiency 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.
It is prohibited and dangerous to obstruct the air
intake, even partially, for the ventilation of the
room in which the boiler is installed.
Due to the danger, functioning is also prohibited
in the same room as suction devices, chimneys
or similar at the same time as the boiler unless
there are additional openings dimensioned in a
way to satisfy the further necessity for air. For the
dimensioning of these additional openings, refer
to qualified technical staff. In particular, an open
fire must have its own air supply.
On the contrary, the boiler cannot be installed
in the same room.

Attention:
the use of components involving use
of 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
barefoot;
- never pull electrical cables or leave the
appliance exposed to weathering (rain,
sunlight, etc.);
- the appliance power cable must not be
replaced 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.
