Use:
The boiler has been constructed according
to current technical standards and the most
stringent safety rules. Despite this, improper
use may endanger persons and property as
well as damaging the boiler itself.
This boiler has been designed as a thermal
generator for closed-loop central heating
systems and for the production of domestic
hot water.
This boiler is only for heating water to a
temperature below that of boiling point at
atmospheric temperature.
Any use different from those outlined herein is
to be considered improper. The manufacturer/
supplier declines any responsibility for damage
or injury caused by improper use.
Using the boiler according to its design also
means respecting the instructions given in
the operation and maintenance manuals
and observing the general inspection and
maintenance conditions.
