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.
