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.
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.
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.
