10/91) and comply, from technical and functional
point of view with the requirements provided in
standards:
›UNI-CIG7129/08
› UNI EN 297 for B-TYPE GAS DEVICES WITH
HEAT CAPACITY d70 kW
› EN 483 for C-TYPE GAS DEVICES WITH HEAT
CAPACITY d70 kW
› UNI EN 677 for CONDENSING GAS DEVICES
WITH HEAT CAPACITY d70 kW
› Performance at 100% Pn and 30% (partial load
Pn) - D.P.R. 412/93 (regulation implementing
Law 10/91 art. 4, paragraph 4) and subsequent
modifications
The gas boilers also comply with the directives
below:
› GAS DIRECTIVE 2009/142/CE
› PERFORMANCE DIRECTIVE 92/42 CEE
› ELECTROMAGNETIC COMPATIBILITY
DIRECTIVE 2004/108/CE
› LOW VOLTAGE DIRECTIVE 2006/95/CEE
The materials used such as copper, brass,
stainless steel create a homogeneous, compact
and functional assembly, easy to install and
manage. In its simplicity, the boiler is equipped

INTRODUCTION

The installation operations described in this section should
be performed 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 as
provided by art. 3 of D.M. n°37 dated 22.01.2008.

1.1.1. GENERAL INSTALLATION
WARNINGS
WARNING
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.
WARNING
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 as
provided by art. 3 of D.M. n°37 dated 22.01.2008.
WARNING
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
Two devices intended for the same use in the
same location or in directly communicating
locations, generating a total heat capacity of
over 35 kW, represent a heating unit, subjected
to the requirements provided by D.M. n°74 dated
12.04.1996 “Approval of the fire prevention technical
rule for design, manufacture and operation of gas-
supplied thermal plants”.
As the device's heat capacity is lower than 35 kW,
the location housing the boiler must meet the
provisions laid down by technical standard UNI
7129-3: 2008.
The capacities of more devices intended for
different uses (e.g. heating and cook top), installed
in a single housing unit must not be added.

1. INSTALLATION
INSTALLER
The device's installation location should be vented
due to the presence of threaded joints on the gas
adduction line (UNI 7129-3: 2008). 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
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’).
1.1.3. REFERENCE LEGISLATION
THE INSTALLER MUST FOLLOW THE DIRECTIVES
BELOW:
› Standards UNI 7129-3: 2008 / 7131 and updates;
› Law dated 9 January 1991 n° 10 and relative
Regulation Implementing (DPR 412/93, modified
by DPR 551/99);
› Dispositions issued by Fire Fighters, local gas
Company and Municipal Regulations.
› Instructions provided by the supplier.
