1.1.9. HYDRAULIC CONNECTION
DANGER
Make sure that the tubes of the water and
heating plant are not used as grounding system for
the electrical plant. There are not suitable for such
use.
WARNING
To prevent voiding the warranty and to
ensure the proper operation of the boiler, please
wash the plant (if possible when hot) with suitable
pickling or descaling solutions in order to remove the
impurities coming from tubes and radiators.
WARNING
If the boiler is installed in a hydrostatic
position lower than those of the user devices
(radiators, fan coils, etc.), mount the shut-off valves
on the domestic water heating circuit to ease the
performance of the maintenance operations if it is
necessary only to empty the boiler.
WARNING
When connecting the equipment to
water supply, avoid excessive bending and recovery
operations from any off axis positioning that may
damage the tubes causing leaks, malfunction or
early wear.
WARNING
In order to avoid any vibrations and noises,
do not use tubes with small diameters or elbows with
small radius and significant cut-off of the passage
sections.
WARNING
Connect the boiler safety drains to a
discharge funnel. The manufacturer is not responsible
for any floods due to safety valve opening in case of
plant overpressure.
DOMESTIC CIRCUIT
In order to prevent limestone build-up and
damages to the domestic water heat exchanger,
the hardness of the domestic supply water
should not exceed 15 °f. However, please check
the characteristics of the water used and install
suitable treating devices.
The heat exchanger coil cleaning frequency
depends on the hardness of the supply water and on
the presence of solid residues or impurities inside
the water that are often present in case of recently
installed plants. Based on the characteristics of
the infeed water, you should install suitable water
treating devices, for residues presence please
install a line filter.
The pressure of the cold infeed water should be
between 0.5 and 6 bar. In case of greater pressure
values, please install a pressure reducer upstream
from the boiler.
HEATING CIRCUIT
In order to avoid any scale or deposits on the
primary exchanger, the hardness of the heating
circuit infeed water should not exceed 25 °f.
However, please check the characteristics of the
water used and install suitable treating devices.
This treatment is mandatory if frequent episodes
of return water or partial or total emptying of the
plant occur.
WARNING
In case the boiler is installed as part of
a low temperature circuit, please install a safety
thermostat on the heating flow, which can stop
the boiler activity in case of high heating flow
temperature. The company assumes no liability for
damage caused to persons or for failure to comply
with these instructions.
