3.7 SYSTEM FLOW AND RETURN PIPE
CONNECTION
The heating flow and return must be connected to the boiler by the
respective 4" fittings F and R as indicated in parag. 2.3.
For heating circuit pipe sizing it is necessary to take into account
the head losses induced by the components of the system and its
configuration.
The layout of the pipes must be set up taking every necessary precaution
to avoid air pockets and to facilitate continuous degassing of the system.
ATTENTION!
Before connecting the boiler to the system proceed
by thoroughly washing the pipes terminating at the
boiler with a suitable product, in compliance with
standards, in order to eliminate metal residues from
machining and welding, any oil and grease that could
affect its operation.
Do not use solvents to wash the system, as they might
damage the system and/or its components.
Failure to observe the instructions in this manual
can cause damage to people, animals and property,
for which the manufacturer will not be held liable.
