5. Secure the hose by tightening the hose clamp.

6. Repeat the same procedure for the other end of the hose by securing it to the regulator on the gas bottle to complete the gas cylinder connection.

7. Always check for gas leaks after installation and whenever a new or refilled gas bottle is used for the first time.

To check for leaks at the connection point:

1. Ensure that the control knobs on the hob are in the OFF position.

2. Open the valve on the Gas bottle.

3. Using a small paintbrush, apply some soapy water to all the connections.

4. If there is a leak, bubbles will appear.

5. If this happens, close the valve on the gas bottle.

6. Check and tighten the connections immediately.

7. Repeat the procedure to ensure that there are no further leaks.

Caution: Never use a naked flame to check for gas leaks.

1. Remove burners, burner caps, and grills from the hob.

2. Turn the hob upside down and place it on a flat surface.

3. Apply the putty supplied in the package on the contours of the lower housing of the hob to prevent foreign substances and liquids from penetrating between the hob and the counter. Make sure the putty does not overlap.

4. Apply the putty by bending it around the corners. Make sure the putty is filled on the base cover contours.

5. Turn the hob again, align it, and place it on the counter.

6. Secure your hob to the counter using the clamp and the screws supplied (wooden spacers may be required).

7. Place the burner plates, burner plate caps, and grills back to their seating after installation.

Gas conversion must only be carried out by a registered installer. Before starting, shut off the gas supply. To change the appliance’s gas type, all injectors must be changed and the flame adjustment for all valves must be set at the reduced flow rate position.

Changing the injectors:

1. Take off the burner cap and burner body.

2. Unscrew injectors by turning them counterclockwise.

3. Fit new injectors.

4. Check all connections for secure fitting and tightness.

Reduced gas flow rate setting for taps:

1. Ignite the burner that is to be adjusted and turn the knob to the reduced position.

2. Remove the knob from the gas tap.

3. Use an appropriately sized screwdriver to adjust the flow rate adjustment screw. For LPG (Butane – Propane), turn the screw clockwise. For natural gas, you should turn the screw counter-clockwise once. The normal length of a straight flame in the reduced position should be 6-7 mm.

4. If the flame is higher than the desired position, turn the screw clockwise. If it is smaller, turn anticlockwise.

5. For the last control, bring the burner to both the high-flame and reduced positions and check whether the flame is on or off.

• Defrost frozen dishes before cooking them.

• Use pots/pans with a cover for cooking. If there is no cover, energy consumption may increase up to 4 times.

• Select the burner which is most suitable for the bottom size of the pot to be used. Always select the correct pot size for your dishes. Larger pots require more energy.

The surface may get damaged by some detergents or cleaning materials. Do not use aggressive detergents, cleaning powder/cream or any sharp objects.

1. Remove all packaging materials.

2. Wipe the surfaces of the appliance with a damp cloth or sponge and dry with a cloth.

• Before frying foods, always dry them well and gently place into the hot oil. Ensure complete thawing of frozen foods before frying.

• Do not cover the pot or pan you use when heating oil.

• Place the pans and saucepans in a manner so that their handles are not over the hob to prevent heating of the handles. Do not place unbalanced and easily tilting cooking vessels on the hob.

• Do not place empty pots and saucepans on cooking zones that are switched on.

• Operating a cooking zone without a pot will cause damage to the appliance. Turn off the cooking zones after cooking is complete.

• As the surface of the appliance can be hot, do not place plastic and aluminum vessels on it.

• Use flat-bottomed saucepans or cooking vessels.

• Put only the appropriate amount of food in saucepans and pans to help prevent overflowing.

• Place saucepans so that they are centered on the cooking zone. When moving the saucepan, lift and place it onto the new cooking zone instead of sliding it.

• Adjust the gas flames so that they do not extend past the bottom of the cooking vessel and ensure that the cooking vessel is centered on the saucepan carrier.

Igniting the gas burners:

1. Keep the burner knob pressed in.

2. Turn the knob counter-clockwise to the large flame symbol. The gas is ignited with the spark created.

3. Adjust the knob to the desired cooking power.

Turning off the gas burners:

Turn the knob to the off (upper) position.

The gas shut off safety system is a countermeasure against blowouts due to fluid overflows or if the flame extinguishes for any reason. The flow of gas to the burner will automatically be terminated.

To operate:

• Push the knob inwards and turn it counter-clockwise to ignite.

• After the gas ignites, keep the knob pressed for 3-5 seconds more to engage the safety system.

• If the gas does not ignite after you press and release the knob, repeat the same procedure by keeping the knob pressed in for 15 seconds.

DANGER: Risk of deflagration in case of unburned gas! Do not press the knob for longer than 15 seconds if there was no ignition. Wait for one minute and then repeat the ignition process.

1. Carefully align the hole in the burner body with the flame failure sensor.

2. Gently lower the burner body into position.

3. Centralise and level the burner cap onto the burner body. The burner cap must be positioned so that it rests centrally on the burner body.

4. Ensure that it is correctly seated. Refit the pot stands.

Switch off the electricity before cleaning the appliance. Allow hot surfaces to cool down.

• Clean the appliance thoroughly after each use to make it easier to remove cooking residues and prevent them from burning during the next use.

• Use warm water with washing liquid, a soft cloth, or sponge to clean the product and wipe it with a dry cloth.

• Always ensure any excess liquid is thoroughly wiped off after cleaning and any spillage is immediately wiped dry.

• Do not use cleaning agents that contain acid or chloride to clean the stainless or inox surfaces and the handle. Use a soft cloth with a liquid detergent (not abrasive) to wipe those parts clean, paying attention to sweep in one direction.

• Do not use aggressive detergents, cleaning powder/cream, or any sharp objects. Do not use steam cleaners or a water jet for cleaning.

1. Remove and clean the saucepan carriers and burner caps.

2. Clean the hob.

3. Install the burner caps and make sure that they are seated correctly.

4. When installing the upper grills, pay attention to place the saucepan carriers so that the burners are centered.

Wipe the glass ceramic surface using a piece of cloth dampened with cold water so as not to leave any cleaning agent on it. Dry with a soft and dry cloth. Residues may cause damage on the glass ceramic surface when using the hob for the next time.

Dried residues should under no circumstances be scraped with hook blades, steel wool, or similar tools. Remove calcium stains (yellow stains) with a small amount of lime remover such as vinegar or lemon juice.

If the surface is heavily soiled, apply the cleaning agent on a sponge and wait until it is absorbed well. Then, clean the surface of the hob with a damp cloth.

Sugar-based foods such as thick cream and syrup must be cleaned promptly without waiting for the surface to cool down. Otherwise, the glass ceramic surface may be permanently damaged.

Clean the control panel and knobs with a damp cloth and wipe them dry. Do not remove the control buttons/knobs to clean the control panel, as the control panel may get damaged.
