True !
We would install black pipe with the drip leg and gas valve at the furnace and water heater and also run black pipe up to at least 6 foot high, then install the CSST, I use (Dimond Back) at that height to prevent a young child from hanging on the CSST. The black pipe is more rigid and we would secure it good. Never had any trouble with doing it that way. I have seen it installed all the way down to the furnace and water heater with a drip leg but I think that is not safe and poor workmanship. (lazyness)
