I had a direct vent today on a 50 gal State Water heater that I have question on. The vent itself makes more of a loop going up then down and through the wall. The pipe loops up about a foot or so before turning down and exiting out. Will this configuration draft properly? The owners manual was there and I looked through it and it gave clearances and a diagram. It did not specifically caution against doing a loop rather than an elbow. Doing some more research online, most install directions show right angle configurations. I did not see any signs of condensate or corrosion. It was installed in 07.
Any qualified expertise appreciated.
As far as I know a ‘direct vent’ always means that draft is provided by a fan. So this is not a direct vent. And it is totally wrong because of the loop, (no dips allowed) it doesn’t matter if it is B vent or not, that thing could kill somebody.
