Instructions for the Installer
8.1.2 Installation to a flush mounting structure
Make a hole in the top of the cabinet of the size shown in the figure, leaving a space "X" of at least 110 mm from the rear edge. The underside of the casing must be fully accessible once the appliance has been installed.
This appliance may be installed against walls higher than the worktop surface, provided the distance of 100 mm shown in the figure is maintained, in order to prevent damage due to overheating. Make sure that there is at least 750 mm between the hob burners and any shelving placed vertically above them (Fig. 2).
2) 
CAUTION: IF YOU ARE INSTALLING A HOB WITH FISH BURNER, THE DISTANCE "X" FROM THE REAR WALL INCREASES FROM 110 mm TO 300 mm.
