Hi, we have a riser cupboard fire door with smoke seals in our office which is on pivot hinges. Can you tell me what the gap should be under the door? . It seems there is bigger gap where the hinge is. Do you get more tolerance with pivot door hinges?

In terms of the threshold gap for fire doors and compliance to BS 8214: 2016, there is no distinction between doors with top & bottom pivots and doors with butt hinges.
