GUARANTEE AND RESPONSIBILITY

Riello guarantees its new products from the installation date, in accord-
ance with the regulations in force and/or the sales contract. At the mo-
ment 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 equipment;

use of the burner with safety devices that are faulty, incorrectly
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 irregularity;

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 Riello components, including spare parts, kits,
accessories and optionals;

force majeure.

Riello furthermore declines any and every responsibility for the fail-
ure to observe the contents of this manual.

SAFETY AND PREVENTION

INTRODUCTION

The Riello burners have been designed and built in compliance with cur-
rent 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. Inat-
tention, thoughtlessness and excessive confidence often cause acci-
dents; 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 dangerous.

In particular:

it can be applied to boilers operating with water, steam, diathermic oil,
and to other users expressly named by the manufacturer;

the type and pressure of the fuel, the voltage and frequency of the elec-
trical power supply, the minimum and maximum deliveries for which the
burner has been regulated, the pressurisation of the combustion cham-
ber, the dimensions of the combustion chamber and the room tempera-
ture must all be within the values indicated in the instruction manual.

Modification of the burner to alter its performance and destinations
is not allowed.

The burner must be used in exemplary technical safety conditions.
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.

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 responsible for the
machine and for the training of the people working around it.

The user:

undertakes to entrust the machine exclusively to suitably trained
and qualified personnel;

must take all the measures necessary to prevent unauthorised
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 equipment
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, operations 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 compromise
operating safety. The manufacturer therefore declines any and all
responsibility for any damage that may be caused by the use of
non-original parts.

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