4.3 Instructions for the condensate discharge
connection
This product is designed to prevent the escape of flue gaseous
through the condensate drainage pipe with which it is equipped; this
is achieved through the use of a special drain-trap located inside the
appliance.
b
All the components of the condensate drainage system must
be correctly serviced as per the manufacturer's indications,
and must not be modified in any way.
The condensate drain outlet system downstream from the appliance
must be made in accordance with the relevant legislation and
regulations in force; this is the responsibility of the installer. The system
must be sized and installed so as to ensure the correct evacuation
of the condensate produced by the appliance and/or collected by the
flue gas evacuation systems. All the system components must be
made to the highest standards, using materials able to withstand the
long-term mechanical, thermal and chemical stress created by the
condensate.
Note: if the condensate drain outlet system is exposed to the risk
of freezing temperatures, always ensure a suitable level of pipe
insulation and consider increasing the diameter of the pipe itself.
The pipe must slope sufficiently to prevent the condensate from
stagnating and guarantee it is correctly drained off. There must be an
examinable disconnection between the condensate drain outlet pipe
of the appliance and the condensate drain outlet system.

if the signal passes near other electrical conductors or mains
voltage conductors (230V).

High voltage connections
The connection to the mains supply must be made via a separation device
with an omnipolar opening of at least 3.5 mm (EN 60335/1 - category
3). The appliance works with alternating current at 230 Volt/50 Hz, and
is in compliance with Standard EN 60335-1. It is obligatory to make the
connection with a safe ground/earth, in compliance with current directives.
b
The installer is responsible for ensuring the appliance is suitably
earthed; the manufacturer will not be liable for any damage result-
b ing from an incorrect or absent earth connection.
It is also recommended to uphold the phase-neutral connection
(L-N).
b
The ground/earth wire must be a couple of cm longer than the others.
b
To create the seal of the boiler use a clamp and tighten it on the
cable grommet used.
The boiler can operate with a phase-neutral or phase-phase supply. It is
forbidden to use gas and/or water pipes to earth electrical appliances.
Use the power cable supplied to connect the boiler to the mains power
supply. If the power cable has to be replaced, use a HAR H05V2V2-F
cable, 3 x 0.75mm 2 , Ø max external 7 mm.
4.6 Gas connection
The connection of the gas supply must be carried out in compliance with
current installation standards. Before making the connection:
- check that the gas supplied corresponds to that for which the boiler has
been prepared (see nameplate).
