Your new hob:

Burner up to 1,75 kW Pan support Triple flame burner up to 3,6 kW Burner up to 3 kW Burner up to 1,75 kW Burner up to 1 kW Grease tray Control knob

Gas burners

Diagram of a rotary knob with directional arrows and a small cross symbol, labeled Fig.1 (no text or symbols on the knob itself)

Each control knob indicates which burner it controls.(Fig.1)

To light a burner, push in the knob for the burner you wish to use and turn it in an anti-clockwise direction to the lighting position. Hold the knob at the maximum position for a few seconds until the burner ignites and then release and set the knob to the desired setting. If the burner does not light at the first attempt, repeat the operation.

If your hob does not come with any kind of automatic ignition system, then light the burners with a naked flame (cigarette lighter, matches, etc.).

If the spark plugs are dirty, then a fault may occur in the ignition system. Keep them completely clean. Clean the spark plugs using a small brush, remembering that the plugs must not receive any kind of violent impact.

If your hob is equipped with burners with safety valves which prevent gas from being released should the burners accidentally go out, proceed to light as described above, but keep the control knob pressed in until the burners light and then for a few more seconds once alight. If complete ignition does not occur, repeat the operation keeping the knob pressed in for approx. 10 seconds.

To turn the burners off, turn the control knob in a clockwise direction to the ●setting.

Your modern functional hob is equipped with progressive valves which permit you to find the perfect flame setting between maximum and minimum.

Depending on the model that you have purchased, your hob may come with a triple-flame burner, the perfect system for cooking paellas, using woks, etc..

Gas appliances create both heat and humidity in the room they are used in. Make sure that your kitchen is properly ventilated: keep natural ventilation outlets open or install a mechanical ventilation system (extractor fan). When using your appliance for a prolonged period of time, it may be necessary to provide additional ventilation e.g. by opening a window (without creating a draught) or turning up the setting on your mechanical ventilation system.

Recommended receptacle diameters (cm.)

Depending on model:

BURNER	MINIMUM ∅ RECEPTACLE	MAXIMUM ∅ RECEPTACLE
Triple flame:		>22 cm
Rapid:	22 cm 26 cm
Semi-rapid:	12 cm 20 cm

Depending on the model that you have purchased, your hob may come equipped with an additional pan support. This pan support is essential when using the triple-flame burner for receptacles with diameters of more than 26 cm, griddles, terracotta casseroles and all kinds of concave receptacles (woks, etc...) (Fig 2).

If you do not have a pan support, then these are available from your Service Centre, code 484138 // 363300.

Coffee pot support: Depending on the model that you have purchased, your hob may come equipped with an additional coffee pot support. This pan support is only for use on the auxiliary burner for receptacles with diameters of less than 10 cm. If you do not have a pan support, then these are available from your Service Centre, code 184200.

The manufacturer cannot be held responsible for the non-use or misuse of these additional pan support.

Cleaning and maintenance:

Illustration of a gas stove with kitchen utensils and a cooking pan (no text or symbols)

DON'Ts

Never use abrasive products, sharp objects, steel scouring pads, knives, etc., to remove stubborn food remains from the hob surface, grates, burners or electric plates.

If your hob comes with a glass or aluminium panel, do not use knives, scrapers or similar utensils to clean the join with the metal.

Do not use steam appliances to clean the hob with. They could damage it.

DOs

Once the appliance is cold, clean it with a sponge and soapy water.

Remove all excess liquid immediately. This will help you avoid unnecessary effort later.

The burners and pans support must be cleaned regularly to keep them clean. This is done by submerging them in soapy water and scrubbing them with a non-metal brush to keep the holes and slits free from obstruction so they can give a perfect flame. Dry the burner covers and grates whenever wet or damp.

Do not allow acid products (vinegar, lemon juice, etc.) to come into contact with the hob. Try to prevent salt from coming into contact with the surface of the electric plate.

After cleaning and drying the burners, make sure that the covers are properly in position on the flame diffuser.

Diagram showing a mechanical assembly with a lid and a base component, no text or symbols present.

If the coating on the electric plates has worn off through use, smear them with a few drops of oil or one of the maintenance products available on the market.

The high temperatures suffered by the cover on the triple-flame burner ring and the stainless steel parts on your hob (plate rings, grease trays, area around burners, etc) may become discoloured over time. This is NORMAL. Clean them after use with a product suitable for stainless steel.

After cleaning the pans support, dry them thoroughly before cooking with them again. The presence of droplets of water or dampness at the beginning of the cooking process may damage the enamel surface.

If the pans support on your hob are supplied with rubber feet, be careful when cleaning as they may come off, leaving thepan support unprotected and scratching the hob surface.

The cleaning product suitable for stainless steel must not be used in the area surrounding the control knobs. The indications (serigraphy) may get deleted.
