INFORMATION ABOUT THE INSTRUCTION MANUAL

INTRODUCTION
The instruction manual supplied with the burner:
- is an integral and essential part of the product and must not be sepa-
rated 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 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.
DELIVERY OF THE SYSTEM AND THE INSTRUCTION MAN-
UAL
When the system is delivered, it is important that:
- the instruction manual is delivered to the user by the system manu-
facturer, 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 Assistance Cen-
tre.
.........................................................................................
.........................................................................................
.........................................................................................
- 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 recommends the
drawing up of a Maintenance Contract.
