Does each of these CSST gas piped need to be bonded separately or is this ok?
Thanks,
Chad
As long as there is a proper bond at the service meter where the CSST first connects and then to the panel/ground, then bonding the manifold itself is the accepted method of bonding the interior runs.
Note: The diagram does not show the CSST to the exterior, but it is allowed in most areas as long as it is sleeved where it passes through a masonry wall, and the bond has proper connection to the CSST connector.
