The glass is held in by a plastic quadrant at either side,the quadrants are held in by 3 screws each at the back,hold the quadrant while removing screws to stop glass falling out then lay fire on it's back to remove quadrants and glass,be careful when removing glass as it's fitted up into canopy,lift glass at the bottom about 5mm then slide down to base to free it,the PCB is now accessible
