INSTRUCTIONS FOR USE
AND MAINTENANCE.
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 at least execute maintenance
operations on a yearly basis in compliance with
what is stated in the relative point at “annual
check and maintenance of the appliance”, in
compliance with national, regional, or local
standards in force. Annual maintenance is
essential to validate the Immergas warranty. We
recommend stipulating a yearly cleaning and
maintenance contract with an authorised local
company.
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 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 an authorised company checks the
efficiency of the ducting or the 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 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 atmospheric agents
(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 blamed on 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.
