Instructions for the installer
In order to ensure correct boiler operation it is necessary to
use a mixing header which guarantees:
- the separation and collection of circuit dirt
- optimal air venting
- hydraulic de-coupling of the two hydraulic circulation
circuits
- balancing of the circuits
3.12 - MIXING HEADER FILTER
UNICAL suggests the installation of a Y filter
on the return pipe so that it can be cleaned if
necessary.
This filter will protect the boiler from the heating
system dirt.
