Introduction 1. Instructions for safe and proper use This manual is an integral part of the appliance and therefore must be kept in its entirety and in an accessible place for the whole working life of the cooking hob. We advise reading this manual and all the instructions therein before using the cooking hob. Also keep the series of nozzles supplied. Installation must be carried out by qualified personnel in accordance with the regulations in force.
Introduction The identification plate, with technical data, serial number and marking is clearly visible under the casing. The plate on the casing must not be removed. Before connecting the device, make sure that it has been regulated for the type of gas that will feed it, checking the label under the casing. Do not put pans without perfectly smooth and flat bottoms on the cooking hob grids. Do not use recipients or griddle plates that extend beyond the external perimeter of the hob.
Instructions for the installer 2. Positioning of hob This appliance shall be installed only by authorized persons in accordance with AS5601 - Gas Installations, any statutory regulations, local gas regulations, municipal building codes, electrical wiring regulations, and the manufacturer's installation instructions. Clearance around the appliance must comply with the requirements of AS5601. The following operation requires building and/or carpentry work so must be carried out by a competent tradesman.
Instructions for the installer The distances in the following drawing refer to the hole on the inner side of the gasket. In case of installation on a hollow compartment with doors, a separating panel has to be placed under the hob. Keep a minimum distance of 10 mm between the bottom of the unit and the panel surface. The panel has to be easily removable to allow access in the event of technical service. Overall dimensions: location of gas and electrical connection points (all measures in mm).
2.2 Clearance above and around domestic appliances Extract from AS5601 REQUIREMENTS 1 Overhead clearances – (Measurement A) Range hoods and exhaust fans shall be installed in accordance with the manufacturer’s instructions. However, in no case shall the clearance between the highest part of the hob of the cooking appliance and a range hood be less than 600 mm or, for an overhead exhaust fan, 750 mm.
Instructions for the installer 2 Side clearances – (Measurements B & C) Where B, measured 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 Clause 5.12.1.2 to a height C of not less than 150 mm above the hob for the full dimension (width or depth) of the cooking surface area. Where the cooking appliance is fitted with a ‘splashback’, protection of the rear wall is not required.
3. Electrical connection Make sure that the voltage and capacity of the power line conform to the data shown on the plate located under the casing. Do not remove this plate for any reason. The plug on the end of the supply cable and the wall socket must be the same type and conform to the current electrical system regulations. Check that the power line is adequately grounded.
Instructions for the installer 4. Gas connection Use pipe-joint compound made for use with Natural U.L.P. gas. The burner it controls is shown next to each knob (the example corresponds to the front left burner). This appliance is suitable for installation with Natural Gas or ULPG (propane). Refer to page 12 for the relevant burner pressure and appropriate injector sizes. When the appliance is to be connected to Natural Gas then the pressure regulator supplied must be fitted to the gas inlet.
be installed. The N.G. regulator must be checked and adjusted to 1.0kPa after installation. U.L.P.G. Can be connected to the inlet fitting directly. The pressure must be checked to ensure it is operating at 2.75kPa. A separate test point fitting must be installed between the piping & the appliance for the pressure to be checked to ensure it is operating at 2.75kPa. 4.
Instructions for the installer 5. Adaptation to different types of gas Before performing any cleaning or maintenance work, detach the appliance from the electrical socket. The hob has been adjusted for natural gas at a pressure of 1.0kPa. For functioning with other types of gas the nozzles must be replaced and the primary air adjusted. To replace the nozzles and regulate the burners, you have to remove the top as described in the following paragraph. 5.1 Removing the hob 1.
5.2 Regulation for ULPG Loosen screw A and push support B all the way. Use a double head wrench to remove nozzle C and assemble the suitable one, following the instructions indicated in the reference charts, with respect to the type of gas to use. The screwing torque of the nozzle should never exceed 3 Nm. Reposition support B so that nozzle C is covered perfectly. Move the Venturi tube D to regulate the air flow until distance “X” is reached indicated in the chart in paragraph “5.
Instructions for the installer 5.3 Regulation for natural gas The hob has been adjusted for natural gas at a pressure of 1.0kPa. To allow the unit to work with this type of gas, perform the same operations described in paragraph “5.2 Regulation for ULPG”, but choose the nozzles and regulate the primary air for natural gas, as shown in the following table and in paragraph “5.4 Regulation of primary air”. After the regulations have been carried out, restore the seals with sealing wax or equivalent material.
6. Final operations Having carried out the above adjustments, reassemble the appliance following, backwards, the instructions in paragraph “5.1 Removing the hob”. 6.1 Regulation of minimum for natural gas Replace the components on the burner and slide the knobs on the gas tap pins. Light the burner and set it at minimum position. Remove the knob and turn the regulation screw inside or next to the gas tap pin (depending on the model) until you get a suitable minimum flame.
Instructions for the installer 6.3 Arrangement of burners on hob BURNERS 1. Auxiliary 2. Semi rapid 3. Rapid 4. Wok 6.4 Lubrication of gas taps After a while, the gas tap may become hard to turn or lock. If this happens, it has to be cleaned inside and re-greased. This must be done by a qualified technician.
Instructions for the user 7. Using the hob Make sure that the flame-baffle crowns, the caps and the grid have been assembled correctly. Grid C (supplied) should be used for “woks” (Chinese pots). Adapter B (supplied) is to be used for small vessels. 7.1 Ignition of the burners with safety device For each knob the corresponding burner is indicated. The device is fit with electronic ignition.
Instructions for the user All containers have to have a flat and smooth bottom. When using fats or oils, be extremely careful that they don’t overheat and catch fire. If the flame accidentally goes out, turn off the control knob and wait at least 1 minute before trying to re-light the burner. 7.3 Diameter of containers (*) 1 2 3 4 Burner Auxiliary Semi rapid Rapid Wok Ø min. and max.

8. Cleaning and maintenance Never use a steam jet to clean the appliance. Before any intervention, disconnect the power supply of the device. 8.1 Cleaning Clean the cooking top regularly every time you use it, obviously after it has cooled. 8.1.1 Regular daily cleaning of the hob In order to clean and preserve the surface, always use specific products only, which do not contain abrasive substances or chlorine-based acid substances.
Instructions for the user CAUTION: do not wash these components in a dishwasher. In normal use of the hob, the stainless steel burner caps and panstands tend to be burnished by the high temperature. Clean these parts using very fine abrasive sponges or similar commercial products. Then use a specific paste polish to restore the steel’s shine. Your local authorised after-sales technician is able to supply professional products for appliance cleaning and care. 8.2.
