Fire Door - Bottom Clearance - NFPA 80 Section

In a previous edition of the NFPA 80 Code Standards, section specifies the maximum clearance between the bottom of a fire-rated door and the finish floor as 3/4" max. I looked at the 2019 edition of the NFPA 80 Code Standards but did not see this section or specification.


Please advise if it has been removed form the 2019 edition, or relocated to a different code section, or is no longer applicable?


Thank you.
