Welcome to ECN forums!!
Yes, there is conflict with the CSST mfg instructions, and areas of the respective codes. I posted an article from the NJ DCA (State) regarding CSST above in this thread.
Within your comments above, the 'iron pipe that enters the building' is the natural gas service? Is it all iron into the ground, or just iron for the metering equipment and point of entry? Reason I ask is most here is plastic in the streets, with metal for metering and distribution on the premise.
