Installation instructions

ENGLISH

The boiler is equipped with a power cable, boiler 

installation requires electric al connection to the 

mains power supply. This connection must be 

made up to standard, as required the regulations 

in force. 

Remember that a bipolar switch must be installed 

on the boiler power line with over 3 mm between 

contacts, easy to access, making maintenance 

quick and safe.

 

ATTENTION!

Comply with the PHASE and NEUTRAL po-

larity since flame detection is Phase Sensi

-

tive.

The power cable must be replaced by technical 

personnel authorised, using original spare parts 

only. Failure to comply with the above can jeop

-

ardise the safety of the appliance.

-  

(Y2 - 9 and terminal board M2) 

   after removing the jumper.

Danger!

Only a qualified technician may perform the 

electrical installation.

Before performing connections or any type of 

operation on electrical parts, always discon-

nect electrical power and make sure that it 

cannot be reconnected accidentally. 

ATTENTION:

The 230 V cables

must run far apart from 

24V cables.
