1.1.1. GENERAL INSTALLATION
WARNINGS
ATTENTION
This machine may be used only for the
purpose for which it has been designed: heat water
to a temperature below boiling point at atmospheric
pressure. Any other use is considered wrong and
dangerous. The manufacturer is excluded from
any contractual or out of contract responsibility for
damage caused to people, animals or property due
to errors during installation.
ATTENTION
This boiler should be installed only
by qualified personnel, having the appropriate
technical training in the field for the installation and
maintenance of components of civil and industrial
domestic hot water production and heating plants.
ATTENTION
After having removed the packing, make
sure the equipment is intact. In case of doubt, do not
use the equipment and contact the supplier.
BEFORE INSTALLING THE BOILER, THE
INSTALLER MUST MAKE SURE THAT THE
FOLLOWING CONDITIONS ARE MET:
› The device is connected to a heating plant and a
water supply network appropriate for its power
and performance.
› The location must be properly vented through
an air vent.
› The air vent must be placed at floor level to
prevent it from being obstructed, protected by
a grid that does not hamper the useful section
of passage.
› The device is suitable for use with the type of
gas available by checking the boiler data plate
(placed on the inner side of the front casing.
› Make sure that the tubes and couplings are
perfectly sealed, without any gas leaks.
› Make sure that the grounding system works
properly.
› Make sure that the electrical systems is
suitable for the maximum power absorbed by
the equipment, value indicated on the data plate.
WARNING
Use only original RADIANT optional or kit
accessories (including electrical).
1.1.2. BOILER LOCATION
ENVIRONMENTAL
REQUIREMENTS
The device's installation location should be vented
due to the presence of threaded joints on the gas
adduction line. The location should be therefore
provided with vents as to ensure air exchange,
with output grid in the natural accumulation area
of eventual gas losses.
WARNING
DO NOT install the boiler in a technical
compartment near a swimming pool or a laundry, to
avoid that the combustion air is exposed to chlorine,
ammonia or alkaline agents that may worsen the
corrosion phenomenon of the heat exchanger. Failure
to observe this caution will void the warranty of the
heat exchanger.
