Safety and prevention

3.1

Background

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.

Namely:
it can be applied to boilers operating with water, steam, diather-
mic oil, and to other uses 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 ambient temperature must all be within the values in-
dicated 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, the user undertakes to ensure that everyone 
knows the use and safety instructions for his own duties.

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 
accepts  no  responsibility  whatsoever  for  any  which  may 
result from the use of non-original parts.

In addition:

Safety and prevention

WARNING

The  manufacturer guarantees  safety  and  proper 
functioning only if all burner components are intact 
and positioned correctly.

must take all the measures necessary to pre-
vent  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 man-
ual.
