"I don't think he needs to worry about the vent.  I think he saw what appeared to be yellowing pipe and a possible burn on the pipe and was concerned. CPVC has a higher temperature rating than ordinary PVC.  Often around 180F under…"

"That black spot looks to me like someone was sloppy with their torch while working on the copper pipes and burned the PVC. The first pipe does look like CPVC I do not recall seeing CPVC listed as approved vent in any instructions. The way PVC cement…"

Dennis Heidner replied to Luis Hernandez's discussion Water heater ventilation question
"The wording from one of Luis's post on April 20th, seemed to imply that the heater was a boiler not simply a water heater.   If the temp measured was using IR point&shoot measurement - my guess is the 180F reading was either…"

"This really looks like burn marks when someone replace copper fittings to the right of the vent.  It also looks like they used CPVC for the first six inches before moving to ordinary PVC.  That could also be why you see "yellow"…"

"If you decide to replace or change out the vent pipe,  it might be quite interesting to save it and have it sectioned where the area appears to be discolored from heat.  If it was indeed heat the discoloring is likely to be all the way…"

Bradford E. White replied to Luis Hernandez's discussion Water heater ventilation question
"This has been a topic of discussion for 20 years now. It is true that appliance manufacturers often sanction PVC (solid, not cellular core as Charles Buell noted), as venting material. This keeps cost down and market share up and there are thousands…"

"make sure the gas modulator / controller valve has propane orifices (jets), if it came from factory with orifices for natural gas (probably did) it will burn hot as hell on propane. it's a pretty common miss."
