Precautions For Installation; Installing The Boiler Bracket - Biasi RINNOVA ADAPTIVE 25S User Manual And Installation Instructions

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 42)
and the correct systems for installing the duct
shown in the instruction sheet provided to-
gether with the flue gas evacuation pipe kit.
• Leave the minimum distances indicated in Fig-
ure 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 in-
stalling 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 condi-
tions the circulating water.
This latter solution, in particular, not only
cleans the system but also provides anti-corro-
INSTALLATION
sion 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 precautions
in order to prevent damaging the boiler.
• Do not add antifreeze or anticorrosion prod-
ucts to the heating water in the wrong concen-
trations or use those with chemical/physical
characteristics that are incompatible with the
boiler's hydraulic components.
The manufacturer does not assume any liability
for this type of damage.

Inform the user about the boiler's anti-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 assem-
bly.
A paper template that contains all the measure-
ments and information for correctly installing 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.
