5.2 Installation precautions
Follow these installation in-
structions:
• Mount the boiler on a strong wall.
• Respect the measurements of the flue
gas evacuation duct (provided in section
"Flue gas outlet dimensions and lengths"
on page 35) and the correct systems for
installing the duct shown in the instruction
sheet provided together with the flue gas
evacuation pipe kit.
• Leave the minimum distances indicated in
Figure 5.1 around the unit.

• 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.

INSTALLATION
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.
• 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
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 33, "Fittings"
page 34, "Flue gas outlet dimensions and
lengths" page 35.
