Calif. High School Gym 90 min. double door

[Rider Rick]

What is the code on replacement of fire doors in existing concrete wall with steel jamb?
Thank you Rick

 

[TheCommish]

replace with equal unless a change has occurred that would effect occupancy or required rating

Is the assembly fire rated or just the doors? Can a school carpenter machine the fire doors with the 90 minute tag and meet the code?

Cut the bottom

In our code, a solid core wood door would provide a 20 minute rating without a label.

Here is my question stated in a different way....

A quantity of 2 @ 90 minute fire doors prefit...meaning the machining will be done at the mfg.
These will be double doors to be hung in the existing jamb. In my experience door always
need to be fitted/planed to fit in the somewhat out of square jamb. By doing any fitting/planing ...
***(My question is)*** Does this void the fire certification/rating and therefore void the label of the fire door?
Thank you!
