4.5.2 is covers pretty much everything that's deemed a hazard.

Unfortunately you cannot mix pipe from different manufacturers. So you cant mix IPEX (blue writing) with Royal York (black writing) and so on. Not on exhaust anyway. Odds are the installers have connected new pipe (blue writing) to old pipe that was there for the previous furnace (red writing) and well ... that's that.
