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?

    Not sure if IFC applies in many ways.

    Will you give the section you are looking at.

    I think he meant IFGC
    404.3 Prohibited locations.
    Piping shall not be installed in or through a ducted supply, return or exhaust, or a clothes chute, chimney or gas vent, dumbwaiter or elevator shaft. Piping installed downstream of the point of delivery shall not extend through any townhouse unit other than the unit served by such piping.

    A duplex is not defined in the code.
    You have a building that has one or two dwelling units in it.
    BUILDING. Building shall mean any one- and two-family dwelling or portion thereof, including townhouses, that is used, or designed or intended to be used for human habitation, for living, sleeping, cooking or eating purposes, or any combination thereof, and shall include accessory structures thereto

    A townhouse is
    TOWNHOUSE. A single-family dwelling unit constructed in a group of three or more attached units in which each unit extends from foundation to roof and with a yard or public way on at least two sides.

    Unless there is 3 or more units then 404.3 does not apply.

    Presumably this "duplex" is on a single parcel; in other words there are no property line dividing the units?

    Even if both units are under same ownership on one parcel; when you say both lines start in the same unit does this mean there's one meter feeding each unit with CSST?

    Should there be separate gas meters that serve each unit then there would be a concern during servicing or repairs an assumption would be made that the gas is turn off to the line in question when if fact it would not.
