INSTRUCTIONS
2.1 CLEANING AND MAINTENANCE.
Attention:
to preserve the boiler’s integrity and
keep the safety features, performance and reli-
ability which distinguish it unchanged over time,
maintenance operations must be carried out on a
yearly basis in compliance with that stated in the
“annual check and maintenance of the appliance”
section, in compliance with national, regional, or
local standards in force.
2.2 GENERAL WARNINGS.
Use of the boiler by unskilled persons or children
is strictly prohibited.
For safety purposes, check that the air intake/
flue exhaust terminals (if fitted) are not blocked
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 opera-
tions 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.

- do not touch the appliance with wet or moist
parts of the body; do not touch when bare-
foot;
- never pull electrical cables or leave the appli-
ance exposed to weathering (rain, sunlight,
etc.);
- the appliance power cable must not be re-
placed by the user;
- in the event of damage to the cable, switch off
the appliance and contact exclusively quali-
fied staff for replacement;
- 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
