Fitting hinges on a fire door

Fire doors must be hung on three fire rated hinges, and each hinge should carry the CE marking and fire identification stamp where it can easily be seen. Fire rated hinges are tested with intumescent hinge pads fitted behind each leaf, so always install them with pads: a 1mm pad for FD30 doors and a 2mm pad for FD60 doors. Use the screws supplied and follow the door manufacturer's fitting instructions to keep the fire certification valid.
