Burners with safety valve - ignition
Some models are equipped with safety valves which automatically shut off the gas delivery
in the event the burner should, for any reason, go out. To relight the burner, turn the knob to
position "tap closed" and repeat the ignition procedure explained in the following paragraphs.
To light one of the burners, turn the gas tap knob to the maximum
delivery position, then press and hold down it for about 4÷5 seconds.
Warnings:
-
Once the burner is light on, adjust the flame by turning the knob to obtain the desired intensity.
The setting must always be positioned between the maximum and minimum, and never
between the maximum setting and the off position.
-
If the burner is difficult to light on, or if the flame is tall or irregolar, turn off immediately
turning the knob to "off" position and call Assistance Service.
-
If the particular nature of the local gas supply makes it difficult to ignite the burners with the knob
turned to the maximum setting, repeat the operation without a pan in position and with the knob
turned to the minimum setting and without pan stands.
-
Warning: The ignition device must not be used for more than 15 seconds. If after this length of time the
burner does not light, or if it goes out again accidentally, wait 1 minute before trying to ignite it again
Grids
The panstand grids are designed to make the appliance easy and safe to use. Always check the
panstand grids are properly positioned before using the appliance. Furthermore, always check the
protective rubber feet are all present and correctly positioned.
Special "WOK" support grid (fig.2)
This is placed on top of the triple crown burner
when using a “WOK” (concave bottom pan).
In order to prevent serious malfunction of the burner,
never use a wok without this special grid
and never use the wok grid for flat bottomed pans
Choosing the right burner
The symbols stamped on the control panel
near the knobs indicate which knob correspond
to which burner. To choose the most suitable burner,
take into account the diameter of
the pan as well as the pan capacity (see table).

These wrong use may cause overheating, damages to the appliance and fire hazzard.
-
Take all precautions possible to avoid spilling liquids onto the hotplate when it is hot.
-
Do not use the appliance if the surface is broken or damaged; in case you find a crack on the
appliance, disconnect immediately he electric supply and contact the After-Sales service.
-
Bear in mind that the cooking zones remain hot for a relatively long time (about 30 min.),
after switching off.
-
Never clean with high-pressure water or steam-cleaning equipment.
-
Do not put flammable materials (paper, plastic, etc…) on the cooking zones (plates or glass-ceramic)
-
Do not allow heavy or sharp objects to fall on the glass-ceramic cook top.

Type of hotplates:
solid plates (EH31BIX)
The cooktop may be equipped with a Ø145 or a Ø180 hotplate, conventional or rapid power.
The conventional hotplate is entirely black, while the rapid hotplate has a red dot in the centre.
Essentially, the rapid hotplate differs from the conventional one because it offers:
-
greater power;
-
more rapid reaching of desired temperature;
Some electric plates are equipped with a safety thermostat that reduce power and stop the tension
in case of overheating of the appliance (for example, if forgiven working).
glass-ceramic hotplates (VH31HLX)
The glass-ceramic cooktop permits rapid vertical transmission of heat from the heating element
below the cooktop to the pots or pans placed on top of it.
Heat does not spread horizontally, thus at a distance of just a few centimetres from the cooking
zone, the glass remains relatively ”cool” to the touch.
This appliance is equipped with a "residual heat" indicator that lights up if the temperature of the hob
is above 70°C, even when turned off.
Residual heat persists for a relatively long time after the cooking zone has been switched off.
Absolutely do not touch the cooking areas or leave flammable objects near it until the lamp is off.
The indicator lamp turn off automatically once the temperature of the cooking zone falls below 70°C.
Barbecue
To turn on the element, turn the knob clockwise; this sets the relative thermostat,
with settings from “1” to “10”.
The pilot light turns on to show that the element is in operation.
It is normal for some types of lamp to show a little light even when the plates are not working.
Using the grid: Before using the grid, it is always advisable to check that it is firmly
positioned and correctly placed on the hob. Also check that the rubber pads it rests on
are intact and properly in place.
Lava rock : Place the rock inside the tray provided and dispose of the bag.
Once it is in place, turn on the heating element.
Fryer
To set the cooking temperature, turn the knob clockwise, up to a maximum setting of 200°C.
When the heating element comes on, two lights, one green and one red, light up.
The red light goes out when the selected temperature is reached.
It is normal for some types of lamp to show a little light even when the hob is not working.
Advice and warnings:
Put the frying oil in the container provided before switching on the heating element.
After cooking, wait for the oil to cool before emptying the container.
After cooking, turn knobs back to the “0” setting.
If the regulator thermostat fails, a thermostat with manual reset will be activated;
this must be reactivated by a skilled engineer.
