Gas connection
During the planning stage, consider the position of supply connections.
The cooktop must be connected to the gas supply with upstream connection of an isolation valve in accordance with the respectively valid regulations. We recommend that the isolation valve be fitted prior to the cooktop to enable isolation of cooktop from gas supply. The valve must be easily accessible at all times.
To find out the factory set gas type, see bottom of cooktop next to gas connection.
Remove plastic cap from gas supply line prior to installation.
Fit regulator (N.G.) or a test point (Universal LPG) directly to the R 1/2” connection.

Direction of gas flow is indicated on the rear of the regulator.

Use pipe compound or thread sealant, properly threaded pipes and careful assembly procedure so that there is no cross threading, etc., which might cause damage or leakage.
Make sure that all connections performed are free of leakage. The manufacturer does not accept any liability for leakage on connections performed by the installer or if the L-tube is moved or twisted.
There are two ways to carry out the connection to the main gas line:
The hotplate can be connected with rigid pipe as specified in AS/NZS 5601.1
Flexible Hose: If installing with a hose assembly, it must comply with AS/NZS 1869, 10 mm ID, class B or D, no more than 1.2 m long and installed in accordance with AS/NZS 5601.1. Ensure that the hose does not contact the hot surfaces of the hotplate, oven, dishwasher or any other appliance that may be installed underneath or next to the hotplate. The hose should not be subjected to abrasion, kinking or permanent deformation and should be able to be inspected along its entire length with the cooktop in the installed position. Unions compatible with the hose fittings must be used and all connections tested for gas leaks.
The supply connection point shall be accessible with the appliance installed.
WARNING: Ensure that the hose assembly is restrained from accidental contact with the flue outlet of an underbench oven.
Before Leaving
Check all connections for gas leaks with soap and water. DO NOT use a naked flame for detecting leaks. Ignite all burners both individually and concurrently to ensure correct operation of gas valves, burners and ignition. Turn gas taps to low flame position and observe stability of the flame for each burner individually and all together. Adhere the duplicate data plate to an accessible location near the hotplate. When satisfied with the hotplate, please instruct the user on the correct method of operation. In case the appliance fails to operate correctly after all checks have been carried out, refer to the authorised service provider in your area.
It should be expressly noted that we cannot accept any liability for direct or indirect damage caused by wrong connection, leakage or improper installation. When being repaired, the appliance must always be disconnected from the mains supply; if required, notify our customer service.

Switching Gasburners on manually
1. Press the control knob for the selected burner and turn it anticlockwise to the highest power setting.
2. Hold an igniter or a naked flame (such as a lighter or a match) against the burner.
Automatic ignition
If the hob has automatic ignition (ignition plugs):
1. Press the control knob for the selected burner and turn it anticlockwise to the highest power level. While the control knob is held down, all the burners will generate sparks. The flame ignites. Wait a few seconds.
2. Release the control knob. 3. Turn the control knob to the required position.
If the burner does not ignite, switch it off and repeat the steps described above. This time, hold the control knob down for longer (up to 10 seconds).
:Warning ­ Risk of deflagration!
If the flame does not ignite after 15 seconds, switch off the burner and open a window or the door to the room. Wait at least one minute before switching the burner on again.
Note: It is important to keep the appliance clean. If the ignition plugs are dirty, this may cause ignition problems. Clean the ignition plugs regularly with a small, non-metallic brush. Take care to prevent the ignition plugs from suffering any heavy knocks.
Safety system
Your hob is equipped with a safety system (thermocouple) that cuts off the gas when the burners are accidentally switched off.
To ensure that this device is active: 1. Switch on the burner as usual. 2. Without releasing the control knob, press and hold it
down firmly for 4 seconds after lighting the flame.
Switching off a burner
Turn the corresponding control knob clockwise to the 0 setting. A few seconds after the burner is switched off, a sound (thud) will be produced. This is not a fault – this means that the safety device is no longer operating.
Warnings
It is normal to hear a soft whistling noise while the burner is operating. When first used, it is normal for the burner to give off odours. This does not pose any risk and does not indicate a malfunction. They will disappear in time.

You should only use cookware with a domed base if your cooktop features a wok burner and the additional wok grid. The additional wok grid must be correctly positioned.

Precautions for use
The following advice is intended to help you save energy and prevent pan damage:
Use pans which are the right size for each burner. Do not use small pans on large burners. The flame must not touch the sides of the pan. Do not use damaged pans, which do not sit evenly on the hob. Pans may tip over. Only use pans with a thick, flat base. Do not cook without using a lid and make sure the lid is properly fitted. This wastes energy.

Always centre the pan over the burner, not to one side. Otherwise it could tip over. Do not place large pans on the burners near the control knobs. These may be damaged by the very high temperatures.

12

Place the pans on the pan supports, never directly on the burner. Make sure that the pan supports and burner caps are correctly positioned before using the appliance. Pans should be placed on the hob carefully. Do not strike the hob and do not place excessive weight on it.
Never use two burners or heat sources to heat one single pan. Do not use grill pans, earthenware casserole dishes, etc. for a long period of time on maximum power.
Do not place anything, eg. flame tamer, asbestos mat, between pan and pan support as serious damage to the appliance may result.
Do not remove the pan support and enclose the burner with a wok stand as this will concentrate and deflect heat onto the hotplate. Do not use large pots or heavy weights which can bend the pan support or deflect flame onto the hotplate.

Table of cooking times
The table below lists the optimal heat settings and cooking times for various types of food. The information given applies when cooking four portions.
The cooking times and heat settings may vary depending on the type of food, its weight and quality, on the type of gas used, and on the material from which the cookware is made. To prepare this dish, stainless steel cookware was mainly used.
Always use cookware that is the right size and place it in the centre of the burner. You can find information about the diameter of the cookware under ~ “Suitable pans”
Information on the table
Each type of food can be prepared in one or two steps. Each step contains information about the following:
~ Cooking method § Heat setting v Cooking time in minutes

en Cleaning and maintenance
Cooking tips Use a pressure cooker to cook creamy soups and
pulses. This significantly reduces the cooking time. If you are using a pressure cooker, follow the manufacturer’s instructions. Add all of the ingredients at the start. Always use a lid when cooking potatoes and rice. This significantly reduces the cooking time. The water must be boiling before you add pasta, rice or potatoes. Then adjust the heat setting to continue boiling. For pan-cooked dishes, heat the oil up first. As soon as you have started the frying, keep the pan at a constant temperature by adjusting the heating setting as required. When preparing several portions, wait until the relevant temperature has been reached again. Turn the food regularly. When cooking soups, cream, lentils or chickpeas, add all of the ingredients to the cookware at the same time.

2Cleaning and maintenance
Cleaning Cleaning and maintenance
Once the appliance is cool, use a sponge to clean it with soap and water.
After each use, clean the surface of the respective burner parts once they have cooled down. If any residue is left (baked-on food, drops of grease etc.), however little, it will become stuck to the surface and more difficult to remove later. The holes and grooves must be clean for the flame to ignite properly.
The movement of some pans may leave metal residue on the pan supports.
Clean the burners and pan supports using soapy water and scrub with a non-wire brush.
If the pan supports are fitted with rubber rests, ensure that these are also cleaned. The rests may come loose and the pan support may scratch the hob.
Always dry the burners and pan supports completely. Water droplets or damp patches on the hob at the start of cooking may damage the enamel.
After cleaning and drying the burners, make sure the burner caps are correctly positioned on the diffuser.
Caution! Do not remove the control knobs when cleaning the
appliance. The appliance may be damaged if moisture finds its way inside. Do not use steam cleaners. This could damage the hob. Never use abrasive products, steel scourers, sharp implements, knives, etc. to remove bits of hardened food from the hob. Do not use knives, scrapers or similar implements to clean the point where the glass meets the burner trims, the metal frames or the glass/aluminium panels, if fitted. Do not put the burner components in the dishwasher.
Maintenance
Always clean off any liquid as soon as it is spilt. This will prevent food remains from sticking to the hob surface and you will save yourself any unnecessary effort.
Never slide pans across the glass surface, as you may scratch it. In addition, try not to drop heavy or sharp objects on the glass. Never strike any part of the hob.
Grains of sand that may come from cleaning fruits and vegetables will scratch the glass surface.
Melted sugar, or foods which contain a lot of sugar which may have spilt, should be cleaned off the hob immediately, using the glass scraper.
