3 EASY TO INSTALL
Each elements of this boiler as been designed to give to the installer the maximum easiness and fastness in
the installation activity: hydraulic, exhaust gas flue & electrical connection.
The PIGMA, even if lighter compared with the old Chaffoteaux range, keeps exactly the same hydraulic
connections for an immediate replacement of the old previous models respecting the existing installation.
Chaffoteaux represents a reference for the market and continues to represent the best solution for the new
installation and replacement of all boilers with the biggest distance between the hydraulic connections and
the wall, 230 mm.
For the flue gas exhaust, every configuration is possible and in case of twin pipe system configuration the
installer has the possibility to connect the air inlet piping on the left- or right-hand side; furthermore the
reduction in the fixing width between the flue gas exhaust and the hydraulic connections (only 830 mm)
mean that the boiler can be installed easily and quickly, even if in case of replacement with rear pipes
installation.
Also for the electrical connections, has been created an installer zone, in the Frontal Panel rear side, for an
easy access to the PCB box where all the connections with the external devices can be easily done.
A wide range of temperature control accessories can be installed, wired (with wires) and wireless (without
wires), in particular the last one permits a complete installation quickly and in a non-invasive way.
Also in terms of function PIGMA has been designed to help the installers in their activity, the Automatic Air
purge” for example facilitates the elimination of any air bubbles present in the heating circuit, optimizing the
activity, reducing the time for the completion of the installation and the noise for the end user.
Another important value of this boiler is its capability to work perfectly integrated with the most complex
domestic system for heating and DHW production.
In the first case, a complete of Multizones Modules:
- up to tree zones monotemperatures
- multizones temperatures up to tree zones (HT+2 LT zones)
Allows a total personalization in the installation
For the DHW production, the boiler is set up for use in a system which uses solar panels in series and in
parallel.
Where forced circulation is used, it can control the system directly with the boiler interface with a small clip in
out to put in the electrical box, already predisposed, and without a specific external device not linked to the
boiler.

4.1.7 New proportional flow meter
The turbine announces in real time the possible variation of flow and by means of the probes, the regulation
is modified instantaneously to have always constant temperatures.
In DHW mode, with a water flow >1.6l/min, the turbine give the information to the electronic to start ignition phase.
It’s possible to remove it easily by the front without using any tool.
