1 Location of thermal protection barrier Installation instructions 9 Ventilation requirements (all countries except UK) Providing adequate ventilation The installer must refer to the current local regulations. The room accommodating the gas cooktop must have adequate natural draught to allow combustion of the gas. The flow of air must come directly from one or more air vents made in the outside walls with a free area of at least 100 cm2. The vents must be positioned close to the floor, preferably on the opposite side to the gas burners of your cooktop (as shown in Figs. 2a and 2b). The vents must be designed in such a way that they cannot be obstructed either from the inside or the outside. When it is not possible to provide the necessary vents, the draught may be supplied from an adjacent room, ventilated in the required manner, provided it is not a bedroom or an area at risk. In this event, the kitchen door must be opened to allow the draught to enter the room. Extracting cooking and gas fumes Important! This appliance is not connected to a device extracting the products of gas combustion. Such a device must be installed and connected in accordance with the installation rules in force. Take special care to provide adequate room ventilation as well. To eliminate cooking and gas fumes, extractor hoods ducted directly to the outside must be installed (Fig. 2a). If this is not possible, an electric fan installed in an external wall or window may be used; the fan should have a capacity to circulate air at an hourly rate of 3 to 5 times the total volume of the kitchen (Fig. 2b). The fan can only be installed if the kitchen has suitable vents to allow air to enter, as described under ‘Providing adequate ventilation’ above.

For rooms with a volume of less than 5 m3, permanent ventilation through a free area of at least 100 cm2 will be required. For rooms with a volume between 5 m3 and 10 m3, permanent ventilation through a free area of at least 50 cm2 will be required, unless the room has a door which opens directly to the outside air, in which case no permanent ventilation is required. For rooms with a volume greater than 10 m3, no permanent ventilation is required. Important! Regardless of room size, all rooms containing the appliance must have direct access to the outside air via an openable window or equivalent. Where there are other fuel-burning appliances in the same room, BS 5440-2: 2000 should be consulted to determine the correct amount of free area ventilation requirements. The above requirements also allow for use of a gas oven and grill, but you need to consult a qualified engineer if there are other gas-burning appliances in the same room. Installation instructions Fastening the cooktop to the bench 1 Turn the cooktop upside down and place it on a soft surface. 2 Spread the seal around the edges, with the adhesive side facing down. 3 Mount the supplied front and rear clamps (F and R) and screws (S) onto the cooktop, as shown (without tightening the screws). 4 Place the cooktop into the cutout, then tighten the screws to clamp the cooktop securely to the bench. 5 Using a sharp cutter or trimmer knife, trim the excess sealing material around the edge of the cooktop. Take care not to damage the benchtop. Note: if your bench is thicker than 40 mm, recess the underside to between 30 and 40 mm.
