Instructions for the installer<br />
3.7 - FLOW AND RETURN PIPE CONNEC-<br />
TIONS<br />
The CH flow and return circuits have to be connected to the<br />
boiler via the respective connections 1” or 1’’¼ as indicated<br />
on page 16.<br />
When determining the size of the CH circuit pipes it is<br />
essential to bear in mind the pressure losses induced by any<br />
of the system’s components and by the configuration of the<br />
same system.<br />
The route of the piping has to be conceived taking all the<br />
necessary precautions in order to avoid air locks and to<br />
facilitate the continuous purging of the system.<br />
WARNING!<br />
Before installing the boiler we recommend<br />
that the system is flushed out with a suitable<br />
product, in order to eliminate any metallic<br />
tooling or welding residues, oil and grime<br />
which could reach the boiler and affect the<br />
proper running of the boiler.<br />
Non-observance of these instructions could<br />
cause injury to persons, animals or damage<br />
to property. The manufacturer shall not be<br />
held liable for any such injury and/or damage.<br />
Ensure yourself that the system’s piping is not<br />
used as the earth clamps for the electrical or<br />
telephonic system. They are absolutely<br />
unsuitable for this use. In a short time this could<br />
cause serious damage to the piping, boiler<br />
and radiators.<br />
