USE AND MAINTENANCE
INSTRUCTIONS
2.1 CLEANING AND MAINTENANCE.
Attention: to preserve the boiler's integrity
and keep the safety features, performance and
reliability, which distinguish it, unchanged over
time, you must execute maintenance operations
on a yearly basis in compliance with what is stated
in the relative point at “annual check and main-
tenance of the appliance”, in compliance with
national, regional, or local standards in force.
We recommend stipulating a yearly cleaning and
maintenance contract with your local technician.
2.2 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.
Do not touch the flue gas exhaust terminal (if pre-
sent) due to the high temperatures it can reach;
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 heating system if antifreeze is not
used;
b) shut-off all electrical, water and gas supplies.
In the case of work or maintenance to structures
near ducting or devices for flue extraction and the
relative accessories, switch off the appliance and
on completion of the operations make sure that
an authorised company verifies the efficiency of
the ducting or the 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.

Attenzione:
the use of components involving
use of electrical power requires some funda-
mental 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 appli-
ance exposed to weathering (rain, sunlight,
etc.);
- the appliance power cable must not be replaced
by the user;
- if the cable is damaged, switch off the appliance
and solely contact an authorised company to
replace it;
- if the appliance is not to be used for a certain
period, disconnect the main power switch.
N.B.: the temperatures indicated by the display
have a tolerance of +/- 3°C due to environmental
conditions that cannot be attributed to the boiler.
At the end of its service life, the appliance must
not be disposed of like normal household waste
nor abandoned in the environment, but must
be removed by a professionally authorised
company. Contact the manufacturer for disposal
instructions.
