If a reduced depth hearth is fitted, the fire must be installed so that the distancefrom the base of the fireplace opening in the wall to the finished floor level is at least72mm. Where there is no floor covering or carpet and the floor is of a type that islikely to be covered in such a way then the distance from the base of the fireplaceopening in the wall to the finished floor level should be increased to at least 147mm.If the lower part of the fascia (the firefront) is free standing, the recommendedreduced hearth depth is 100mm. This is necessary to support the firefront (See figure5 for appliance dimensions). To protect from the risk of burns and ignition of clothing a tactile separator shall beused.
