Improper use Risk of damage to surfaces

• Do not use aluminium foil to cover the burners or hob body.
• Cooking vessels or griddle plates should be placed inside the perimeter of the hob.
• All pans must have smooth, flat bottoms.
• If any liquid does boil over or spill, remove the excess from the hob.

3.2 First use

1. Remove any protective film from the outside or inside of the appliance, including accessories.
2. Remove any labels (apart from the technical data plate) from accessories.
3. Remove and wash all the appliance accessories (see 4 Cleaning and maintenance).

3.3 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 anticlockwise 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 O and wait at least 60 seconds before lighting it again.

Correct positioning of the grids

Under the grids there are silicone rests with a hole that must be centred onto the matching fixing pins on the surface.

Make sure that the grids are simply centred on their respective burners, without forcing them to be raised or tilted. If they are, repeat the positioning procedure.

If you find that a pan is particularly unstable, make sure that the grids have not been positioned incorrectly.

Installing the grids

To position the grids correctly on their burners, follow the instructions below:

70 cm

60 cm

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 flame-spreader crowns are correctly engaged in the burner holes.

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.

Cookware diameters:

AUX:7-18cm.
- SR: 10 - 24 cm.
RR:12-24cm.
R:14-26cm.
- UR3: 12 - 26 cm
- UR2:12 - 26 cm.

During cooking, in order to avoid burns or damage to the hob or top, all pans or griddles must be positioned inside the outer edge of the hob and at a minimum distance of 50~mm from the knobs.

Limitations on griddle use

A few precautions are necessary if you wish to use a griddle:

Griddles must never protrude beyond the edge of the hob.
Aluminium griddles with Teflon anti-stick coating should be pre-heated for a maximum of 5 minutes in order to avoid damage to the appliance and the Teflon coating. After pre-heating, place the foodstuffs on the griddle to cook them; do not exceed 40 minutes of total use for the griddle.
- If one of the burners close to the wooden rear wall is an ultra-rapid burner (UR3 or UR2), leave a gap of at least 160 ~mm between this wall and the edge of the griddle;
- Do not use griddles or plates to cook or heat food on the ultra-rapid/triple crown burner (UR3) or the ultra-rapid/double crown burner (UR2).
It is not recommended to use earthenware or steatite (soapstone) pans to cook or heat food.
- Do not allow the burner flames to extend beyond the edge of the griddle;

• Leave a gap of at least 160 ~mm between the edge of the griddle and the side wall;
• Do not place the griddle over more than one burner at the same time.
• Never use the griddle for more than 40 minutes.

4 Cleaning and maintenance

4.1 Instructions

Improper use

Risk of damage to surfaces

• Do not use steam jets to clean the appliance.
• Do not use cleaning products containing chlorine, ammonia or bleach on parts made of steel or that have metallic surface finishes (e.g. anodizing, nickel- or chromium-plating).
• Do not use rough or abrasive materials or sharp metal scrapers.
• Do not wash removable parts such as the hob grids, flame-spreader crowns and burner caps in the dishwasher.

4.2 Cleaning the appliance

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, non-abrasive products and a wooden or plastic tool, if necessary. Rinse thoroughly and dry with a soft cloth or a microfibre cloth.

Cleaning and maintenance

Cooking hob grids

Remove the 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 grids 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 crowns 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. Refit the flame-spreader crowns, making sure that they are correctly positioned in their housings with their respective burner caps.

Knobs

Do not use aggressive products containing alcohol or products for cleaning steel and glass when cleaning the knobs, as these products could cause permanent damage.

The knobs should be cleaned with a soft cloth dampened with warm water, then dried carefully. They can easily be removed by pulling them upwards.

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.

After cleaning, dry the appliance thoroughly to prevent water or detergent drips from interfering with its operation or creating unsightly marks.

5 Installation

5.1 Safety instructions

Heat production during appliance operation Risk of fire

• Check that the carcass material is heat resistant.
• Check that the carcase has the required openings.

Veneers, adhesives or plastic coatings on adjacent furniture should be temperature-resistant (>90^) , otherwise they might warp over time.

The minimum clearance between a ventilation hood and the cooking surface must be at least the distance indicated in the ventilation hood installation instructions.

The minimum clearances must also be respected for the edges of the hob on the back as indicated in the mounting illustrations.

5.2 Section cut from the countertop

The following operation requires building and/or carpentry work and must therefore be carried out by a competent tradesman.

Installation can be carried out on various materials such as masonry, metal, solid wood or plastic laminated wood as long as they are heat resistant (>90^)

Create an opening with the dimensions shown in the figure in the countertop of the carcase.

opens on bottom and on rear

If installed on top of an oven, the latter must be equipped with a cooling fan.

Over empty kitchen unit or drawers

If there are other pieces of furniture (lateral walls, drawers, etc.), dishwashers or fridges under the hob, a double-layer wooden base must be installed at least 10mm from the bottom of the hob to avoid any accidental contact. It must only be possible to remove the double-layer base using suitable equipment.

opens on bottom
opens on rear

Failure to install the double-layer wooden base exposes the user to possible accidental contact with sharp or hot parts.

Hob seal

To prevent leakage of liquid between the frame of the hob and the work surface, put the insulating seal provided in position before assembly.

1. Refer to the dimensions in the figure, bearing in mind that the long front side must be flush with the hole.

1. Use light pressure to make the seal stick to the edge around the hole cut in the worktop.
2. Carefully trim the surplus edge away from the seal.

5.4 Fastening with brackets

The figures below show the exact holes to be used to correctly attach the hob to the work surface with brackets.
