even if it is transferred to another owner or user, or to
another system. If the manual is lost or damaged, another
copy must be requested from the Technical Assistance
Service of the area;
is designed for use by qualified personnel;
offers important indications and instructions relating to the
installation safety, start-up, use and maintenance of the burner.

Information and general warnings
2.1.4 Delivery of the system and the instruction
manual
When the system is delivered, it is important that:
the instruction manual is delivered to the user by the system
manufacturer, with the recommendation to keep it in the
room where the heat generator is to be installed.
The instruction manual shows:
– the serial number of the burner;
– the address and telephone number of the nearest Assist-
ance Centre.
The system supplier must carefully inform the user about:
– the use of the system;
– any further tests that may be required before activating the
system;
– maintenance, and the need to have the system checked at
least once a year by a representative of the manufacturer
or another specialised technician.
To ensure a periodic check, the manufacturer recom-
mends the drawing up of a Maintenance Contract.
2.2 Guarantee and responsibility
The manufacturer guarantees its new products from the installa-
tion date, in accordance with the regulations in force and/or the
sales contract. At the moment of the first start-up, check that the
burner is integral and complete.
In particular, the rights to the guarantee and the responsibility will
no longer be valid, in the event of damage to things or injury to
people, if such damage/injury was due to any of the following
causes:
incorrect installation, start-up, use and maintenance of the
burner;
improper, incorrect or unreasonable use of the burner;
intervention of unqualified personnel;
carrying out of unauthorised modifications on the equipment;
use of the burner with safety devices that are faulty, incor-
rectly applied and/or not working;
installation of untested supplementary components on the
burner;
powering of the burner with unsuitable fuels;
faults in the fuel supply system;
use of the burner even following an error and/or an irregularity;
repairs and/or overhauls incorrectly carried out;
modification of the combustion chamber with inserts that
prevent the regular development of the structurally estab-
lished flame;
insufficient and inappropriate surveillance and care of those
burner components most likely to be subject to wear and tear;
the use of non-original components, including spare parts,
kits, accessories and optional;
force majeure.
The manufacturer furthermore declines any and every re-
sponsibility for the failure to observe the contents of this
manual.

WARNING
Failure to observe the information given in this
manual, operating negligence, incorrect installation
and carrying out of non authorised modifications
will result in the annulment by the manufacturer of
the guarantee that it supplies with the burner.

Safety and prevention
3.1 Introduction
The burners have been designed and built in compliance with
current regulations and directives, applying the known technical
rules of safety and envisaging all the potential danger situations.
It is necessary, however, to bear in mind that the imprudent and
clumsy use of the equipment may lead to situations of death risk
for the user or third parties, as well as the damaging of the burner
or other items. Inattention, thoughtlessness and excessive confi-
dence often cause accidents; the same applies to tiredness and
sleepiness.
It is a good idea to remember the following:
The burner must only be used as expressly described. Any
other use should be considered improper and therefore dan-
gerous.
In particular:
it can be applied to boilers operating with water, steam, diather-
mic oil, and to other users expressly named by the manufacturer;
the type and pressure of the fuel, the voltage and frequency of the
electrical power supply, the minimum and maximum deliveries for
which the burner has been regulated, the pressurisation of the
combustion chamber, the dimensions of the combustion cham-
ber and the room temperature must all be within the values indi-
cated in the instruction manual.
Modification of the burner to alter its performance and desti-
nations is not allowed.
The burner must be used in exemplary technical safety con-
ditions. Any disturbances that could compromise safety must
be quickly eliminated.
Opening or tampering with the burner components is not
allowed, apart from the parts requiring maintenance.
Only those parts envisaged by the manufacturer can be
replaced.
3.2 Personnel training
The user is the person, body or company that has acquired the
machine and intends to use it for the specific purpose. He is re-
sponsible for the machine and for the training of the people work-
ing around it.
The user:
undertakes to entrust the machine exclusively to suitably
trained and qualified personnel;
undertakes to inform his personnel in a suitable way about
the application and observance of the safety instructions.
With that aim, he undertakes to ensure that everyone knows
the use and safety instructions for his own duties;
Personnel must observe all the danger and caution indica-
tions shown on the machine.
Personnel must not carry out, on their own initiative, opera-
tions or interventions that are not within their province.
Personnel must inform their superiors of every problem or
dangerous situation that may arise.
The assembly of parts of other makes, or any modifications,
can alter the characteristics of the machine and hence com-
promise operating safety. The manufacturer therefore
declines any and every responsibility for any damage that
may be caused by the use of non-original parts.
In addition:
3 Safety and prevention
WARNING
The manufacturer guarantees safety and proper
functioning only if all burner components are intact
and positioned correctly.
the user must take all the measures neces-
sary to prevent unauthorised people gaining
access to the machine;
the user must inform the manufacturer if
faults or malfunctioning of the accident pre-
vention systems are noticed, along with any
presumed danger situation.
Personnel must always use the personal pro-
tective equipment envisaged by legislation
and follow the indications given in this manual.
