WATER CONNECTION
A new safety unit must be installed at the intake to the water heater,
in a frost-free environment, with dimensions of 3/4" and with
pressure of 0,7 MPa (7 bar), compliant with local regulations in force.
A pressure reducer (not supplied) is needed when pressure is more
than 0,5 Mpa (5 bar) and it will be placed on the main supply.
Connect the safety unit to a drain pipe kept in the open air, in a frost-
free environment, with a permanent downward gradient, to remove
any expansion water from the heating process, or drainage water
from the water-heater.
No device (shut-off valve, pressure reducer, etc.) should be
placed between the safety group and the cold water supply line
of the water heater.
5. Refer to the installation
diagrams. The size of space
needed for the appliance to
be correctly installed is
specified in the chapter

7. This product is intended for use at a maximum altitude of 2000m.
Do not block, cover or block the air inlets and outlets of the

It is imperative to install a retention tank under the water heater
when it is positioned in a false ceiling, attic or above inhabited
premises. A drain connected to the sewer is required.
