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 sep-
arated from it; it must therefore be kept carefully for any necessary
consultation and must accompany the burner even if it is trans-
ferred to another owner or user, or to another system. If the manual
is lost or damaged, another copy must be requested from the Tech-
nical Assistance Service of the area;
- is designed for use by qualified personnel;
- offers important indications and instructions relating to the installa-
tion 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 supplied 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
Centre;
..................................................................................
..................................................................................
..................................................................................
- The system supplier carefully informs the user about:
- the use of the system,
- any further tests that may be necessary before the system is
started up,
- maintenance and the need to have the system checked at least
once a year by the manufacturer or another specialised techni-
cian. To ensure a periodic check, the manufacturer recom-
mends the drawing up of a Maintenance Contract.
