INSTALLATION INSTRUCTIONS
ATTENTION!
This boiler is intended solely for the use for
which it was expressly designed. Any other
use is to be considered improper and there-
fore dangerous.
This boiler heats water at a temperature
lower than the atmospheric pressure boiling
temperature.
Before connecting the boiler, have profes-
sionally qualified personnel:
a) Thoroughly wash all the piping of the sys-
tem to remove any residues or impurities,
which could jeopardise proper operation
of the boiler.
b) Check that boiler is set up to operate with
the available type of fuel.
This can be seen written on the package
and on the technical feature plate;
c) Check that the chimney/flue has an
appropriate draught, without any bottle-
necks, and that no exhausts from other
appliances are inserted, unless the flue
has been
implemented to accommodate several
utilities according to specific standards
and regulations in force. Only after this
check
can the fitting between the boiler
and chimney be mounted;
ATTENTION!
If there is dust and/or if there are
aggressive/corrosive vapours present in
the installation room, the appliance must
be protected suitably and must be able to
operate independently from the air in the
room.
ATTENTION!
Mount the appliance respecting the minimum
distances required for installation and main-
tenance.
The boiler must be connected to a central
heating system and/or domestic hot water
supply network compatible with its efficiency
and output.
