INSTALLATION

5.1 Warnings

Protective gloves must be worn.
The unit must discharge the
combustion products directly
outside or into a suitable ex-
haust flue designed for that pur-
pose and in compliance with
current national and local stan-
dards.
The unit is not suitable for re-
ceiving condensate from the
combustion product evacuation
system.
The combustion air must not
contain chlorine, ammonia or al-
kaline agents.
Installing a boiler near to a
swimming pool, washing ma-
chine or laundry room results
in an aggressive mixture in the
combustion air around the boil-
er.
Before installation, it is mandatory to thor-
oughly wash all of the system pipes with
non-aggressive chemical products. The
purpose of this procedure is to remove any
residues or impurities that could jeopardise
good boiler operation.
After washing, the system must be treated.
The conventional warranty does not cover
any problems resulting from failure to follow
these instructions.
Check:
• That the boiler is suitable for the type of
gas supplied (see adhesive label). If it is
necessary to adapt the boiler to a different
type of gas, see section "GAS CONVER-
SION" on page 59.
• That the characteristics of the electric, wa-

ter and gas supply networks comply with
those on the plate.
The combustion products may only be dis-
charged using the flue gas exhaust kits pro-
vided by the manufacturer, as they are an
integral part of the boiler.
For LPG gas (Propane G31), the installa-
tion must also comply with the requirements
of the distributing companies and with the
requirements of current technical standards
and laws.
The safety valve must be connected to a
suitable discharge duct to avoid flooding if
it is triggered.
The condensate outlet siphon must be con-
nected to the residential condensate outlet
duct; it must be possible to inspect it and it
must be implemented in such a way as to
avoid the condensate freezing (UNI 11071
and related standards).
The electric installation must comply with
technical standards, in particular:
• It is mandatory to connect the boiler to
an effective earthing system via a specific
terminal.
• A multiway switch must be installed near
the boiler to allow complete disconnection
in conditions of category III over-voltage.
For the electrical connections, refer to
section "Electrical connections" on page
41.
• The electric conductors for connecting
the ambient thermostat and the exter-
nal sensor to the boiler must go through
different channels than those for the mains
voltage (230 V), as they are supplied with
low safety voltage.
If the power supply cable is
damaged, it must only be re-
placed by a qualified technician.
