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.
Symbols used in the manual
In some parts of the manual you will see triangular DANGER
signs. Pay great attention to these, as they indicate a situation of
potential danger.
2.1.2 General dangers
The dangers can be of 3 levels, as indicated below.

Delivery of the system and the instruction manual
When the system is delivered, it is important that:
The instruction manual is supplied 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 carefully informs the user about:
– the use of the system,
– any further tests that may be necessary before the system
is started up,
– maintenance and the need to have the system checked at
least once a year by the manufacturer or another special-
ised technician.
To ensure a periodic check, the manufacturer recom-
mends the drawing up of a Maintenance Contract.

Information and general instructions
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 non authorised modifications on the equip-
ment;
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 power supply system;
use of the burner even following an error and/or an irregular-
ity;
repairs and/or overhauls incorrectly carried out;
modification of the combustion chamber with inserts that
prevent the regular development of the flame, as structurally
established;
insufficient and inappropriate surveillance and care of those
burner components most subject to wear and tear;
use of non-original components, including spare parts, kits,
accessories and optionals;
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 installa-
tion and the carrying out of non authorised modifi-
cations 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;
must take all the measures necessary to prevent unauthor-
ised people gaining access to the machine;
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;
must inform the manufacturer if faults or malfunctioning of
the accident prevention systems are noticed, along with any
presumed danger situation.
Personnel must always use the personal protective equip-
ment envisaged by legislation and follow the indications
given in this manual.
Personnel must follow all the danger and caution indications
shown on the machine.
Personnel must not carry out, on their own initiative, opera-
tions or interventions that are not within their province.
Personnel are obliged to 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 all responsibility for any damage that may
be caused by the use of non-original parts.
