BORETTI CFBG902AN3 Instruction On Mounting And Use Manual page 18

Choice of the burner
on the control panel, near every knob there is a diagram that indicates which
burner is controlled by that knob.
The suitable burner must be chosen according to the diameter and the
capacity used. The burners and pans must be used in accordance with the
following instructions:
DIAMETERS OF PANS WHICH MAY BE USED ON THE BURNERS
BURNERS
Auxliliary
Semi-rapid
Rapid
Dual (with ONLY inner crown operating)
Dual (with inner + outer crown operating)
do not use pans with concave or convex bases
It is important that the diameter of the pot be
suitable to the potentiality of the burner so
as not to compromise the high output of the
burners and therefore energy waste.
A small pot on a large burner does not give you
a boiling point in a shorter amount of time since
the capacity of heat absorption of a liquid mass
depends on the volume and the surface of the pot.
Caution
Make sure the pans are central to the burner for maximum stability and
greater efficiency.
Make sure the pans are not in contact with the control knobs, otherwise
the flame could overheat the knobs and permanently damage them.
