In particular: ■ Never touch the appliance with wet hands or feet; ■ do not operate the appliance barefooted; ■ do not allow children or other incapable people to use the appliance without supervision. The manufacturer cannot be held responsible for any damages caused by improper, incorrect or illogical use of the appliance.
INSTALLATION CAUTION: ■ ■ ■ ■ ■ ■ This appliance must be installed in accordance with these installation instructions, local gas fitting regulations, municipal building codes, water supply regulations, electrical wiring regulations, AS5601 / AG 601 - Gas Installations and ony other relevant statutory regulations. This appliance shall be only be serviced by authorized personnel. This appliance is to be installed only by an authorised person.
N.B. The connection of the appliance to earth is mandatory. If the installation requires alterations to the domestic electrical system call a qualified electrician. He should also check that the socket cable section is suitable for the power drawn by the appliance. Replacing the power cord must be done by a qualified electrician in accordance with the instructions supplied by the manufacturer and in compliance with established electrical regulations.
CLEARANCES: Installation clearances and protection of combustible surfaces shall comply with the current local regulations e.g. AG 601 (AS 5601) - Gas Installations code.

The installation shall comply with the dimensions in Figures 3 and 4, bearing in mind that: ■ 100 mm 750 mm 450 mm A minimum clearance of 20 mm has to be kept between the bottom of the cooking hob and the top of an appliance or a shelf. To ensure this clearance mount the spacers supplied with the appliance as shown in the figure 5.
■ Side clearances - Where the dimensions from the periphery of the nearest burner to any vertical combustible surface is less than 200 mm, the surface shall be protected in accordance with local regulations in force to a height of not less than 150 mm above the hob for the full dimension (width or depth) of the cooking surface area.
GAS SUPPLY: ■ ■ ■ ■ This appliance is suitable for use with Natural Gas or ULPG. (Check the “gas type” sticker attached to the appliance). For Natural Gas the gas supply must be regulated to obtain a pressure of 1 kPa with the two largest burners operating. For ULPG models connect the gas supply directly to the appliance test point adaptor (supplied with the conversion kit) and ensure that the supply pressure is regulated to 2.75 kPa. Do NOT force the ”elbow“ rotation prior to loosening nut.
5. Check the minimum burner setting by quickly rotating the gas control knob from the maximum to the minimum position, the flame must not go out. If adjustment is required carry out the “minimum burner setting adjustment" procedure described below. 6.

CONVERSION PROCEDURE (to convert to Natural gas or to ULPG) REPLACING THE INJECTORS The conversion procedure must be carried out only by an authorised person. This appliance is suitable for use with Natural gas or Universal LPG (check the “gas type” sticker attached to the appliance). The nominal gas consumption and injector size details are provided in table at page 11. To replace the injectors proceed as follows: ■ Remove pan supports and burners from the cooktop.
MINIMUM BURNER SETTING ADJUSTMENT Check whether the flame spreads to all burner ports when the burner is lit with the gas tap set to the minimum position. If some ports do not light, increase the minimum gas rate setting. Check whether the burner remains lit even when the gas tap is turned quickly from the maximum to the minimum position. If the burner does not remain lit, increase the minimum gas rate setting. The procedure for adjusting the minimum gas rate setting is described below.
USE and CARE CAUTION: ■ This appliance must be used only for the task it has explicitly been designed for, that is for domestic cooking of foodstuffs. Any other form of usage is to be considered as inappropriate and therefore dangerous. Do not use this appliance as a space heater. ■ Do NOT place combustible materials or products on this appliance at any time. ■ Do NOT spray aerosols in the vicinity of this appliance while it is in use.
LIGHTING GAS BURNERS ■ Check that the electricity is switched on to allow spark ignition. ■ Make sure that all controls are turned to zero. ■ The gas flow to the burner is controlled by a tap incorporating a safety cut-off valve. If the burner flame should go out for some reason, the safety valve will automatically stop the gas flow. The switch of the electric ignition is incorporated in the knobs.
LIGHTING GAS BURNERS (FITTED WITH SAFETY CUT-OFF VALVE) In order to light the burner, you must: 1 – Turn the knob fig. 18 in anti-clockwise direction up to the maximum aperture, push in and hold the knob; this will light the gas. If there is no mains electrical supply, bring a lighted match close to the burner. 2 – Wait about ten seconds after the gaslights before releasing the knob (starting time for the valve). 3 – Adjust the gas valve to the desired position.
COOKING HINTS FOR GAS HOBS ■ ■ ■ ■ ■ The burners are different sizes, and can be used in different ways. The largest can be used for boiling, to seal meat or foods that are cooked quickly, and the smallest for stews and sauces. Always ensure that you use the correct size of saucepan. For fast boiling, make sure the flame just reaches the edge of the pan. Flames going up the side of the pan means wasted heat and the contents of the pan will take longer to boil.
Cleaning and Maintenance GENERAL ADVICE ■ ■ ■ ■ ■ Before you begin cleaning, you must ensure that the appliance is switched off. It is advisable to clean when the appliance is cold and especially when cleaning the enamelled parts. Avoid leaving alkaline or acidic substances (lemon juice, vinegar, etc.) on the surfaces. Avoid using cleaning products with a chlorine or acidic base. Do not use a steam cleaner because the moisture can get into the appliance thus make it unsafe.
CORRECT REPLACEMENT OF THE BURNERS It is very important to check that the burner flame distributor F and the cap C has been correctly positioned (see figs. 22 and 26) failure to do so can cause serious problems. Check that the electrode “S” (fig. 22) is always clean to ensure trouble-free sparking. In the models with safety device, check that the probe “T” (fig. 22) next to each burner is always clean to ensure correct operation of the safety valves.
TRIPLE RING BURNER The triple ring burner must be correctly positioned (see fig. 23); the burner rib must be located in position as shown by the arrow. Then position the cap A and the ring B (fig. 24 - 25). The burner correctly positioned must not rotate (fig.24).
SERVICE AND MAINTENANCE If the ignition spark fails to ignite or does not light the gas, check the following items before calling our Customer Service Centre to obtain the nearest Authorised Service Agent: ■ ■ ■ Burner is reassembled and located correctly. Spark electrode and white ceramic are clean and dry. 240 VAC power supply is connected. Contact the local gas utility or our Customer Service Centre to obtain the nearest Authorized Service Agent. ■ ■ ■ You can smell gas when all burners are turned on.
