5.2 Precautions for installation

Follow these installation instruc-
tions:
• 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
36) and the correct systems for installing
the duct shown in the instruction sheet pro-
vided 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, before
installing the boiler, carefully clean it in or-
der 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
INSTALLATION
cleans the system but also provides anti-cor-
rosion protection by forming a protective 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 pre-
cautions 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 chemical/
physical characteristics that are incompati-
ble with the boiler's hydraulic components.
The manufacturer does not assume any liabil-
60
ity for this type of damage.
Inform the user about the boiler's an-
ti-freeze function and any chemical prod-
ucts 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 terminate
with female fittings, 3/4" for the gas fitting 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.

tion "Dimensions" on page 34, "Fittings"
