Burner knobs
For lighting and adjusting the hob burners. Press and turn the knobs anti-clockwise to in order to light the relative burners. Turn the knobs to the zone between the maximum and minimum setting to adjust the flame. Return the knobs to the position to turn off the burners.
See General safety instructions.
A gas leak can cause an explosion.
If you smell gas or there are faults in the gas system:
Malfunctions
Any of the following indicate a malfunction and you should contact a service centre.
Practical tips for using the hob
For better burner efficiency and to minimise gas consumption, use pans with lids and of suitable size for the burner, so that the flames do not reach up the sides of the pan. Once the contents come to the boil, turn down the flame far enough to ensure that the liquid does not boil over.
Burner | Pan diameter |
AUX | 12 - 18 cm |
SR | 14 - 24 cm |
R | 20 - 26 cm |
UR | 20 - 30 cm |
All the appliance's control and monitoring devices are located together on the front panel. The burner controlled by each knob is shown next to the knob. The appliance is equipped with an electronic ignition device. Simply press the knob and turn it anti-clockwise to the maximum flame symbol, until the burner ignites. If the burner does not light in the first 15 seconds, turn the knob to and wait 60 seconds before trying again. After lighting, keep the knob pressed in for a few seconds to allow the thermocouple to heat up. The burner may go out when the knob is released: In this case, the thermocouple has not heated up sufficiently.
Wait a few moments and repeat the operation. Keep the knob pressed in longer.
In case of an accidental switching off, a safety device will be tripped, cutting off the gas supply, even if the gas cock is open. Return the knob to and wait at least 60 seconds before lighting it again.
Use of containers
When cooking, to avoid burns, damage to the hob or top, all containers or steak pans must be positioned within the perimeter of the hob.
At the end of each use, always check that the knobs are in position (off).
Correct positioning of the flame-spreader crowns and burner caps
Before lighting the hob burners, make sure that the flame-spreader crowns are correctly positioned in their housings with their respective burner caps. Make sure that the holes in the burners are aligned with the igniters and thermocouples. Also ensure that the flamespreader crowns are correctly engaged in the burner holes.
Correct positioning of the grids
To install the grids follow the instructions as shown in the following pictures:
Pay attention, moreover, to the wording "FRONT" below each grid at the front, as a further indication on how to position the grids properly on the hob.
Position the grids so that the "FRONT" wordings face towards the hob knobs.
Precautions when using the griddle
A few precautions are necessary if you wish to use a griddle:
Cooking hob pan support grids
Remove the pan support grids and clean them in lukewarm water and non-abrasive detergent. Make sure to remove any encrustations. Dry them thoroughly and return them to the hob.
The continuous contact between the pan supports and the flame can cause modifications to the enamel over time in those parts exposed to heat. This is a completely natural phenomenon which has no effect on the operation of this component.
Flame-spreader crown and burner caps
For easier cleaning, the flame-spreader crowns and the burner caps can be removed. Wash them in hot water and non-abrasive detergent. Carefully remove any encrustation, then wait until they are perfectly dry. Replace the flamespreader crowns, making sure that they are correctly positioned in their housings with their respective burner caps.
Igniters and thermocouples
For correct operation the igniters and thermocouples must always be perfectly clean. Check them frequently and clean them with a damp cloth if necessary. Remove any dry residues with a wooden toothpick or a needle.
To keep the surfaces in good condition, they should be cleaned regularly after use. Let them cool first.
Ordinary daily cleaning
Always and only use specific products that do not contain abrasives or chlorine-based acids. Pour the product onto a damp cloth and wipe the surface, rinse thoroughly and dry with a soft cloth or a microfibre cloth.
Food stains or residues
Do not use steel sponges and sharp scrapers as they will damage the surface. Use normal, nonabrasive products and a wooden or plastic tool, if necessary. Rinse thoroughly and dry with a soft cloth or a microfibre cloth.
The hob does not work:
The cooking results are unsatisfactory:
The hob smokes:
The fuses blow or the circuit breaker of the residential electrical system trips repeatedly.
The appliance must be installed by a qualified technician and according to the regulations in force.
Appliance factory set for: natural gas G20 at a pressure of 20 mbar.
See General safety instructions.
Connection to the gas mains can be made using a continuous wall steel hose in compliance with the guidelines established by the standards in force. To use other types of gas, see the chapter "Adaptation to different types of gas". The appliance's gas connector has a ½" external thread (ISO 228-1).
Connection with a steel hose
Make the connection to the gas mains using a continuous wall steel hose whose specifications comply with the applicable standard.
Carefully screw the connector 3 to the gas connector 1 of the appliance, placing the seal 2 between them.
Connection with a steel hose with conical fitting
Make the connection to the gas mains using a continuous wall steel hose whose specifications comply with the applicable standard.
Carefully screw the hose connector 3 to the appliance's gas connector 1 (½" thread ISO 228-1), placing the seal 2, provided, between them. Apply insulating material to the thread of connector 3 and then screw the steel hose 4 onto the connector 3.
Connection to LPG
Use a pressure regulator and make the connection on the gas cylinder following the guidelines set out in the standards in force.
The supply pressure must comply with the values indicated in the "Burner and nozzle characteristics table".
Room ventilation
The appliance should be installed in rooms that have a permanent air supply in accordance with the standards in force. The room where the appliance is installed must have enough air flow for the regular combustion of gas and the necessary air change in the room itself. The air vents, protected by grilles, must be the right size to comply with current regulations and positioned so that no part of them is obstructed, not even partially.
The room must be kept adequately ventilated in order to eliminate the heat and humidity produced by cooking: In particular, after prolonged use, you are recommended to open a window or to increase the speed of any fans.
Extraction of the combustion products
The combustion products may be extracted by means of hoods connected to a natural draught chimney whose efficiency is certain or via forced extraction. An efficient extraction system requires precision planning by a specialist qualified in this area and must comply with the positions and clearances indicated by the applicable standards.
When the job is complete, the installer must issue a certificate of conformity.

Adaptation to different types of gas
If other types of gas are to be used, the nozzles must be replaced and the primary air must be adjusted. The top of the hob has to be removed in order to replace the nozzles and adjust the burners.
In order to be able to replace the nozzles, the appliance must be removed from the built-in unit.
Only for models with lateral UR:
For all models:
After removing the top, proceed as follows:
Adjusting the minimum setting for natural or town gas
Adjusting the minimum setting for LPG
Tighten the screw located at the side of the cock spindle clockwise all the way.
Following adjustment to a gas other than the one originally set in the factory, replace the gas setting label on the appliance with the one corresponding to the new gas. The label is inserted inside the nozzle pack (where present).
Lubricating the gas cocks
Over time the gas cocks may become difficult to turn and get blocked. Clean them internally and replace the lubrication grease.
Lubrication of the gas cocks should be performed by a specialised technician.
