Weil McLain 97+ boiler: PP or CPVC?

Hi:
I'm installing the above system in my house. I would like to vent with polypropylene, but the manual states that 1st pipe connection to the boiler must be CPVC, which has a lower max temp.
I called them asking about this and they said it was because the engineers tested the system with CPVC.
Since I would like to run this rig with a return temp that would approach the max temp for CPVC, I would feel better venting it with PP. So, PP makes better sense and is safer, but I would risk voiding of warranty.
Any thoughts?
