2. Installation Instruction
1. TITOLO
What follows determines the validity of the warranty.
1. The installation must:
- Be performed by a qualified installer.
- Include, where necessary, a pressure reducer for the inlet
water.
- Include a relief valve calibrated as shown on the technical
data label affixed to the boiler.
- Include an expansion tank (see expansion tank sizing table
) commensurate with the sizes of the boiler (it is recom-
mended to arrange for the calculations to be performed by
a heating engineer).
2. Before start-up check tightening of the flange screws.
3. The temperature of the contents of the boiler must always
be below 95°C.
4. Internal cleaning must be performed every 12 months.
5. To prevent corrosion the electronic anode supplied with
the boiler must be installed.
6. As is known, contact between different metals can cause
corrosion.
In this sense, it is advisable to insert an appropriate dielec-
tric coupling between the attachments located inside the
boiler and the corresponding pipes.
7. The electrical conductivity of the water must not be less
than 150 μS/cm or greater than 1000 μS/cm.
Expansion tank dimensioning
Values in litres relating to:
- pre-load pressure of 2.5 bar
- relief valve calibration pressure of 6.0 bar
- expansion from 10 to 90°C.
In systems with domestic water recirculation rings, the volume of the water in the pipes should also be considered.

Electronic anode
The boilers EURO V are delivered with nr. 1 electronic anode.
The connection for the electronic anode is located on the top
of the boiler (Attachment T).
The anode has an 1/2"M attachment: a reduction from 1"1/4M
.
to 1/2"F is required (not supplied).
For the initial operation of the anode electronic see the man-
ual supplied.
