fire rated csst line??

  1. E

    Are there any fire rated CSST?

    I haven't currently found any specs stating there are. I have a duplex in which both lines start in the same unit. One CSST line runs into the other unit. (404.3) in the 2015 IFC says that a line must stay in the unit it's in. I was curious if there were any ways to navigate around that?
