Nonmetallic pipe floor penetration, 2hr, C-AJ-2110, 3D - can a wall thickness less than Schedule 40 for FRPP vented piping system be used with this listing? Is the Sch 40 wall thickness the maximum, minimum, or absolute for this listing? Should I request an EJ for a different wall thickness?
Hi Tom - for CAJ 2110 (and all other listings), the wall thicknesses allowed will always be specified. So for this specific one, the only wall thickness allowed is Sch 40. You can submit for an EJ request for guidance on any other wall thicknesses.
