Practical tips for using the burners
To obtain maximum efficiency from the burners, it is advisable
to use only pans with a diameter that is suitable for the
burner being used, so that the flame does not extend beyond
the pan base (see following table).
The hob is fitted with pan reducing
support (fig.1), which should only be
used on the auxiliary "A" burner (small).
When a liquid starts boiling, it is advisable to turn the flame
down just enough to keep the liquid simmering.

The air inflow may also be obtained from an adjoining room,
provided the latter is not a bedroom or a room where there
is a risk of fire, such as garages, mews, fuel stores, etc. and
is ventilated in compliance with the standards in force.
Air from the adjoining room to the one to be ventilated may
be made to freely pass through permanent apertures with a
cross section at least equal to that indicated above. These
apertures may also be obtained by increasing the gap
between the door and the floor (fig.3B). If an electric fan is
used for extracting the combustion products, the ventilation
aperture must be increased in relation to its maximum
performance. The electric fan should have a sufficient
capacity to guarantee an hourly exchange of air equal to 3-
5 times the volume of the kitchen. Prolonged, intensive use
of the appliance may require extra ventilation, e.g. an open
window or a more efficient ventilation system by increasing
the extraction power of the electric fan if installed. Liquid
petroleum gas descends towards the floor as it is heavier
than air. Apertures in the outside walls in rooms containing
LPG cylinders should therefore be at floor level, in order to
allow any gas from leaks to be expelled. Do not store LPG
cylinders (even when empty) in basements/rooms below
ground level; it is advisable to keep only the cylinder in use
in the room at any one time and connected far from heat
sources which could raise its temperature to above 50 °C.
fig.5
Installation above an oven
Suitable precautions must be taken to ensure that the
installation is in compliance with current accident-prevention
regulations regarding electrical and gas connections.
Both the electricity supply cable and the gas pipe must not
touch hot parts of the oven housing, in order to avoid
overheating. When installing above a built-under oven without
forced cooling ventilation, suitable air vents should be
provided for as shown in fig.6 (inlet at least 200 cm² from the
bottom, outlet at least 120 cm² from the top part) to allow
adequate ventilation inside the housing unit.
Also a wooden panel "A" should be installed beneath the
hob as insulation, positioning it at a minimum distance of 15
mm from the hob housing (fig.6).
Fixing to the housing unit
Proceed with fixing to the housing unit as follows (fig.7):
· mount the hooks "B", partly tightening the provided screws
"A" into the relative holes;
· position the provided sealing gasket "X" 5÷6 mm from the
edge of the installation hole, matching up the two ends of

• For trouble-free operation, suitable use of energy and longer
life of the appliance, make sure that the supply pressure
complies with the values indicated in the table 1 "burners
and nozzles specifications, otherwise install a special
pressure regulator on the supply pipe in compliance with
current standards and regulations.
· Having obtained the low flame setting required and with
the burner lit, abruptly change the position of the knob
several times from minimum to maximum and vice versa
and check that the flame does not go out.
· In the event of a malfunction on appliances with the security
device (thermocouple) when the gas supply is set at
minimum, increase the minimum supply levels using the
regulator screw.
• Connect in such a way that the appliance is subjected to
no strain whatsoever.
