Attention:

 Immergas declines all liability in the 

event of damage caused by the inclusion of auto-

matic filling that is not its own brand.
In order to meet the system requirements es-

tablished by EN 1717 and in observance of local 

technical regulations in force on the pollution 

of drinking water, we recommend installing 

an anti-backflow kit to be used upstream of 

the cold water inlet connection of the boiler. 

We also recommend using a category 1, 2 or 

3 heat transfer fluid (ex: water + glycol) in the 

boiler’s primary circuit (CH circuit), as defined 

in standard EN 1717.

Attention: 

to preserve the duration of appliance 

efficiency features, we recommend the installation 

of a suitable device for water treatment in presence 

of water whose characteristics can lead to the 

deposit of lime scale.

Condensate drain.

 To drain the condensate 

produced by the appliance, it is necessary to 

connect to the drainage system by means of 

acid condensate resistant pipes, with an internal 

Ø of at least 13 mm. The system connecting the 

appliance to the drainage system must be carried 

out in such a way as to prevent freezing of the 

liquid contained in it. Before appliance ignition, 

ensure that the condensate can be correctly re-

moved. After first ignition, check that the drain 

trap is filled with condensate (para. 1.21). Also, 

comply with national and local regulations on 

discharging waste waters.

In the event condensate is not discharged into 

the wastewater drainage system, a condensate 

neutraliser must be installed to ensure com-

pliance with the parameters established by the 

legislation in force.

1.9  ELECTRIC CONNECTION.

The operations described below must be performed 

after after having disconnected the electrical supply 

from the appliance. 

The electrical system must be built in compliance 

with technical standards and all legislation in 

force. The boiler has an IPX5D protection rating 

for the entire appliance. Electrical safety of the 

appliance is reached only when it is correctly 

connected to an efficient earthing system as 

specified by current safety standards.

Attention:

 Immergas S.p.A. declines any respon-

sibility for damage or physical injury caused by 

failure to connect the boiler to an efficient earth 

system or failure to comply with the reference 

standards.
Also ensure that the electrical installation corre-

sponds to maximum absorbed power specifica-

tions as shown on the boiler data-plate. 

Boilers are supplied complete with an “X” type 

power cable without plug. The power supply 

cable must be connected to a 230V ±10% / 

50Hz mains supply respecting L-N polarity and 

earth connection; 

, this network must also 

have a multi-pole circuit breaker with class III 

over-voltage category. 

The main switch must be installed outside 

the rooms in a position that is indicated and 

accessible.

When replacing the power supply cable, contact a 

qualified company (e.g. the Immergas Authorised 

After-Sales Technical Assistance Service). The 

power cable must be laid as shown (Fig. 1-3).

In the event of mains fuse replacement on the 

connection terminal board, use a 3.15A fast fuse.

For the main power supply to the appliance, 

never use adapters, multiple sockets or exten-

sion leads.

Important:

 if the Digital Remote Control is 

used, arrange two separate lines in compliance 

with current regulations regarding electrical sys-

tems. No boiler pipes must ever be used to earth 

the electric system or telephone lines. Ensure 

elimination of this risk before making the boiler 

electrical connections.

•

Low temperature system installation.

 The 

boiler can directly supply a low temperature 

system, limiting the value of the “P02” pa-

rameter, which defines the generator’s flow 

temperature. In this situation it is good practice 

to insert a safety device in series with the power 

supply and boiler. This device is made up from 

a thermostat with a temperature limit of 55 

°C. The thermostat must be positioned on the 

system flow pipe at a distance of over 2 metres 

from the boiler.
