CERTIFICATION: Look for a label or a plug to show that the door is certificated and check the instructions/certificate supplied.
COMPATIBILITY: Essential Ironmongery such as locks, latches, closers and hinges MUST be CE marked, firmly fixed with no missing screws and compatible with the door leaf’s certification. The choice of frame/lining/casing and intumescent/smoke seals (fitted at the top and sides of the door) should also be compatible
ALTERATIONS: Cutting apertures for glazing and air transfer grilles will make certification VOID as will trimming the door more than is permitted or planing off certification markings
GAPS : The gap between door and frame at the top and sides should be 2-4 mm and the threshold gap as per manufacturers instructions (typically around 8-10 mm)
OPERATION: Check that the closer shuts the door onto the latch from any position
