says use 304 Stainless Steel. They have an exception for venting into a lined chimney with another gas appliance. Then galvanized pipe is acceptable. All joints must be sealed w/ high temp silicone.

No PVC. Highest AFUE 82.4.

doubt it

Ed,

I have a Weil Mclain HE series 2 which is the induced draft and "improved" model. PCV is not specified for mine and I would imagine not for the one you are looking at either. My stack temp runs over 300*. Is there an issue with short cycling or very low water temps? (Just a couple of thoughts from a non-professsional)
