Instructions for the installer
3.8 - FLOW AND RETURN PIPE CON-
NECTIONS
The CH flow and return circuits have to be connected to the
boiler via the respective connections 2½“ M and R as indicated
on page 11.
When determining the size of the CH circuit pipes it is essential to
bear in mind the pressure losses induced by any of the system’s
components and by the configuration of the same system.
The route of the piping has to be conceived taking all the ne-
cessary precautions in order to avoid air locks and to facilitate
the continuous purging of the system.
WARNING!
IT IS ABSOLUTELY FORBIDDEN TO FIT ON-
OFF VALVES ON THE GENERATOR TO THE
FORE OF THE SAFTEY DEVICES
WARNING!
Before installing the boiler we recommend
that the system is flushed out with a suitable
product in order to eliminate any metallic
tooling or welding residues, oil and grime
which could reach the boiler and affect the
proper running of the boiler.
Non-observance of these instructions could cause injury
to persons, animals or damage to property.
The manufacturer shall not be held liable for
any such injury and/or damage.
Ensure yourself that the system’s piping is not
used as the earth clamps for the electrical or te-
lephonic system. They are absolutely unsuitable
for this use. In a short time this could cause se-
rious damage to the piping, boiler and radiators.
