Installation:

Important: The flyscreen MUST be removed if the grille is supplying combustion and cooling air to a boiler, stove or fire. Remove flyscreen if not required. Carefully fix metal spring clips into the back of the louvre. Position clips inside the tube or hole and push firmly until the louvre is flush with the brickwork or inside the face. We recommend you mastic around the inside edge of the louvre for extra adhesion to brickwork (especially with 150mm (6″) diameter tubes and holes).
