Pre-installation warnings
This appliance heats water at a temperature below boiling point. It must be connected to a
heating system and a hot water circuit compatible with the functions and power of the
boiler (refer to technical details). Before connecting the boiler, you must:
Clean the appliance pipes carefully to remove any threading and welding
residues or dirt that may impair the correct operation of the appliance.
Check that the boiler is suitable for use with the type of gas available (read the
instructions on the packing label and the boiler data plate).
Check that the flue is not blocked or connected to any other discharge pipe,
except when the flue has been designed for other uses, complying with the
Regulations in force.
Check that the existing flue connections are adequately cleaned and free of
scale deposits as any disconnection may obstruct the passage of fumes and
result in dangerous situations.
Make sure that unsuitable flue connections are ducted.
There is risk of scale deposits and low performance of the boiler components if
the water is very hard.
Location
The appliance must be installed on a vibration-free solid
wall.
No flammable objects must be near the boiler.
Warning
Make sure that the area where the appliance is installed and
the systems to which it is connected comply with the
regulations in force
