Can CSST pipe be run to a gas fireplace insert from outside the home through brick as what is in picture? If so what kind of protection if any does the pipe need from the pipe being in direct contact with the brick. Not too sure is has very good abrasion resistance…
Masony must be ‘sleeved’ where the non-rigid piping passes through it.
Also, the CSST appears to be painted? NOT allowed!!

I figured as much. You shouldn’t have it where your dog can eat the sheathing either…
Thanks for the info JJ, much appreciated!
