Your barbecue needs to have an air inlet located underneath the area where the charcoal is placed (typically a charcoal grid or perforated plate). In addition, there needs to be a minimum height of 3in / 7,5cm between the lower air inlet and the charcoal support. Note that you do not need to use the Clever Fire Lighter base as long as your fire lighter can rest directly on the barbecue air inlet. See the user guide for more info.
