• Leave 5 cm of free space in front of the
boiler if it is inserted in a cabinet, shelter
or niche.
• In the case of an old heating system, be-
fore installing the boiler, carefully clean it
in order to remove any sludgy deposits
that have formed over time.
• We recommended installing a purification
filter in the system or using a product that
conditions the circulating water.
This latter solution, in particular, not only
cleans the system but also provides an-
ti-corrosion protection by forming a pro-
tective film on the metal surfaces and
neutralising the gases in the water.
Filling the central heating sys-
tem:
• If the boiler is installed in rooms where
the ambient temperature could fall below
0°C, it is recommended to take the proper
precautions in order to prevent damaging

the boiler.
• Do not add antifreeze or anticorrosion
products to the heating water in the wrong
concentrations or use those with chemi-
cal/physical characteristics that are in-
compatible with the boiler's hydraulic
25
components.
The manufacturer does not assume any lia-
bility for this type of damage.
Inform the user about the boiler's an-
ti-freeze function and any chemical
products added to the heating system.
5.3 Installing the boiler bracket
The boiler is provided with a bracket for as-
sembly.
A paper template that contains all the mea-
surements and information for correctly in-
stalling the support is provided.
The hydraulic and gas system must termi-
nate with female fittings, 3/4" for the gas fit-
ting and for the heating delivery and return,
and 1/2" for the DHW inlet and outlet, or
with welded copper pipes with, respectively,
18 mm Ø and 14 mm Ø.
For measurements and useful data see sec-
tion "Dimensions" on page 29, "Fittings"
page 29, "Flue gas outlet dimensions and
lengths" page 30.
