Installation instructions
3.6.2 - RECIRCULATION PUMP
For correct generator operation, a recirculation pump must
be installed in the boiler.
The recirculation pump, supplied in an optional kit, must be
connected as indicated in the figure.
If it is not installed, besides limiting the boiler's lifespan, it
will invalidate the warranty.
ATTENTION!
The hardness of the mains water supply conditions the
boiler's lifespan.
Depending on the hardness of the mains water supply, the
possibility of installing appropriate domestic water soften-
ers has to be taken into consideration in compliance with
DM n° 443 of 21/12/90.
It is always recommended to treat water with a
hardness greater than 15°f.
