Information and general warnings

2.1 Information about the instruction manual

2.1.1 Introduction

The instruction manual supplied with the burner:

is an integral and essential part of the product and must not

be separated from it; it must therefore be kept carefully for

any necessary consultation and must accompany the burner

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 Ser-

vice 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.

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 Assis-

tance 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 date of

installation, 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;

continuation of use of the burner when a fault has occurred;

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;

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 installa-

tion and carrying out of non authorised modifica-

tions will result in the annulment by the

manufacturer of the guarantee that it supplies with

the burner.

20182250 6

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 uses expressly foreseen by the manufactur-

er;

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, 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 manufacturing company

therefore accepts no responsibility whatsoever for any which

may result from 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.

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.
