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.
ATTENTION
This Appliance must be used exclusively
in a pressurized central heating system and is not
suitable for pool heating.
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 boiler has a thermal power over 35 kW and,
therefore, it must be installed only into a heating
unit.
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.
WARNING
If the temperature in the boiler installation
location goes below -10 centigrades, please fill
the plant with anti-freeze liquid and insert and
electrical resistances kit (see chapter ‘ANTI-FREEZE
PROTECTION’).
WARNING
The manufacturer will not be held
responsible for damages caused by incorrect
installation not in conformity with the over mentioned
instructions and not protected adequately from the
freeze.
1.1.3. REFERENCE LEGISLATION
The installation must be realized according to
the requirements of current legislation and in
compliance with local technical regulations,
according to the indications of the good technique.
This appliance must be installed by an authorised
person in accordance with this instruction manual,
AS/NZS 5601 – Gas installations (installation and
pipe sizing), local gas fitting regulations, local
electrical regulations, local water regulations,
local health regulations, Building Code of Australia
and any other government authority.

1.1.9. SYSTEM ACCESSORIES
DIVERTER VALVE KIT
The kit allows combining the thermal generator
with a remote boiler for the production of domestic
hot water (cod. 26097LP, fig. 1).
In this configuration, it is possible to manage the
domestic circuit in an independent manner, by
implementing a diverter valve which ensures the
power supply of the serpentine upon the pre-
heating request of the boiler.
The kit is completed with a probe for the external
boiler and with a power supply cable of the diverter
valve which is connected directly to the electronic
board of the generator.
HYDRAULIC SEPARATOR
In order to always ensure to the heat generator an
operation without problems related to two low heat
capacities (due, for example, to closed radiators or
to impurities of various type), it is strictly necessary
to install a trip unit, as an alternative, a heat
exchanger which separates the hydraulic circuit.
Choosing a separation system in the detriment of
another is exclusively imposed by the type of the
system.
In case of a new system or in case of replacement of
the generator with the possibility to wash the water
pipes, it is recommended to install a hydraulic
separator (code 12-01735, fig. 1).
The hydraulic separator creates an area with
reduced load loss, which allows hydraulically
rendering independent the primary and secondary
circuits connected to it. With the hydraulic separator
you can thus have a production circuit with constant
heat capacity and a distribution circuit with variable
heat capacity, operation conditions typically specific
to modern air-conditioning systems.

1. INSTALLATION
INSTALLER
Particular attention should be given, during the
design phase, to possible temperature variations
to which the circuits can be subject due to the
generated mixing inside the hydraulic separator.
A secondary circuit with a heat capacity higher than
the circulatory one of the primary circuit generates,
in fact, by means of the hydraulic separator, a
delivery temperature lower than the one of the
primary circuit.

MINIMAL TECHNICAL SPACES
In order to allow the access inside the boiler for
maintenance operations, you have to respect the
minimum technical spaces indicated in figure 1.
WARNING
The incorrect slopes of the device can
cause the incorrect discharge of condensate by
means of the discharge duct with consequent
condensate stagnation inside the condensate
module.
WARNING
The boiler must be installed only on a
vertical solid wall, able to sustain its weight.
WARNING
The boilers have the electrical protection
degree IPX5D. The outdoor installation in partially
protected environments (platform roof, balcony -
see fig. 2) is allowed in compliance with the related
standards. The Company is not held liable for
installations in environments with a temperature
under –10°C or non-compliant with the above
indications.

WALL MOUNTING BY MEANS OF FIXING BRACKET
WARNING
In order to avoid condensate stagnations inside the condensate module, check that the boiler is
slightly inclined towards the rear part (1-1.5°) in order to evacuate the condensate.
WARNING
The device must be installed only on a vertical solid wall, able to sustain its weight.
In order to fix the thermal generator on the wall, proceed as follows:
1. fix on the wall (fig. 1), using the fisher, the upper bracket;
2. hook the eyelets of the boiler into the adequate hooks (fig. 2);
3. unscrew the fixing screws of the lower bracket (fig. 3) ensuring the free sliding of the bracket (fig. 4)
towards the boiler;
4. adjust the inclination of the boiler (fig. 5) by sliding the lower bracket ensuring an inclination of the
boiler, against the vertical, of about 1–1.5°.

INSTALLATION ON SELF-SUPPORTING FRAME
WARNING
During the installation of the heat generator, pay maximum attention to the installation of
the self-supporting frame. The frame must rest on a perfectly flat surface and, when supported against
the wall, the latter must be perfectly angled. The incorrect slopes of the device can cause the incorrect
discharge of condensate by means of the discharge duct with consequent condensate stagnation inside
the condensate module. The correct installation of the frame allows obtaining, acting on the lower bracket,
a counterslope of the device against the perpendicular.
In order to mount the frame and therefore the generator, proceed as follows:
1. check the angle of the wall with the floor;
2. assemble the side profiles 3 and 4 on the pillars 1 and 2 (fig. 1);
3. assemble the side pillars 1 and 2 on the horizontal crossbeam 5;
4. assemble the central crossbeam 8 and the lower one 7;
5. complete the assembly, position the frame binding it to the wall 9 (if provided) and on the floor 10;
6. mount the upper bracket 6 and hook the eyelets of the boiler into the adequate hooks 11;
7. make sure that the frame is angled, adjust the inclination of the boiler by means of the lower bracket
(see "Wall mounting by means of fixing bracket") ensuring an inclination of the boiler, against the
vertical, of about 1–1.5°;
8. complete the installation by assembling the hydraulic components.
