The electronic board has a number of jumpers (JPX) that allow to
configure the boiler.
To access the board, proceed as follows:
- set the main system switch to OFF
- loosen the screws (

) that hold the housing in place (fig. 12)
- move the base of the shell forward and then upwards in order to
free it from the frame (fig. 13)
- turn the instrument panel forward
- unscrew the two screws of the small cover on the electronic
board to have access to the terminals (fig. 14).

The connection of the
6WDUW$TXD&RQGHQV%,6
boiler to the gas
supply must be carried out in compliance with current installation
standards.
Before carrying out the connection, it is necessary to ensure that:
- the gas type is suitable for the appliance
- the piping is thoroughly clean.
9
The gas feeding system must be adapted to the boiler output
and must be equipped with all the safety and control devices
prescribed by the current standards. the use of a

Once the installation is done, check that the junctions carried
out are sealed.

For installation, follow the instructions supplied with the kit.
In this configuration, the boiler is connected to the flue gas outlet
pipe of ø 80 mm through an adaptor of ø 60-80 mm.

In this case, the combustion air is picked up from the boiler
installation room (which must be a suitable technical room
with proper ventilation).
