INSTRUCTIONS FOR
INSTALLATION
3.1 - GENERAL WARNINGS
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 professionally
qualified personnel:
a) Thoroughly wash all the piping of the system
to remove any residues or impurities which
could jeopardise proper operation of the
boiler, even from a hygienic point of view.
b) Check that boiler is set up to operate with the
available type of fuel.
The type of fuel can be seen written on the
package and on the technical feature plate.
c) Check that the chimney/flue has an appropri-
ate draught, without any bottlenecks, and that
no exhausts from other appliances are insert-
ed, unless the flue has been implemented to
accommodate several utilities according to
specific standards and prescriptions in force.
Only after this check can the fitting between
the boiler and chimney/flue be mounted.
