USE

Precautions

See General safety instructions.

A gas leak can cause an explosion.
If you smell gas or there are faults in the gas system:

• Immediately turn off the gas supply or close the valve on the gas cylinder.
• Extinguish all naked flames and cigarettes.
• Do not turn on power switches or appliances and do not remove plugs from power sockets. Do not use phones or mobile phones inside the building.
• Open the window in order to ventilate the room.
• Call customer assistance services or your gas supplier.

Malfunctions
Any of the following indicate a malfunction and you should contact a service centre.

• The burners do not ignite properly.
• It is difficult to keep the burners lit.
• The burners go out when the appliance is in use.
• It is difficult to turn the gas cocks.

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.

Using the hob

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:

1. Lay the lateral grids on the hob paying attention to position the front teeth facing the knobs.
   
2. Lay the centre grid engaging the notches in the teeth of the lateral grids.
   

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:

• The griddle must not extend beyond the edge of the hob.
• Do not place the griddle over more than one burner at the same time.
• The griddle can be pre-heated on the burner at maximum power for no more than 10 minutes.
• Make sure that the burner flame does not extend beyond the edge of the griddle.
• Keep a distance of at least 160 mm between the griddle and the side and/or rear wall, especially if it is placed on an Ultra-Rapid burner.
• It is not recommended to use earthenware or steatite griddles.
• Never use the griddle for more than 40 minutes.

CLEANING AND MAINTENANCE

Cleaning the hob

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.

Cleaning the surfaces

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.

What to do if...

The hob does not work:

• Make sure that the hob is connected and that the main switch is turned on.
• Make sure that there is no power failure.
• Make sure that the fuse has not blown. In this case replace the fuse.
• Make sure that the circuit breaker of the residential electrical system has not tripped. In this case, reset the circuit breaker.

The cooking results are unsatisfactory:

• Make sure that the hob is properly ventilated and that the air inlets are unobstructed.

The hob smokes:

• Let the hob cool down and clean it once cooking is complete.
• Make sure that the food has not spilled out of the pan and use a larger cooking vessel, if needed.

The fuses blow or the circuit breaker of the residential electrical system trips repeatedly.

• Call Technical Support or an electrician.
