I been looking at Rheem and I saw photo post here showing Rheem with horizontal concentric termination. Does Trans permit the same termination?
I been "interviewing" the vendors mostly Rheem, but got a number from a friend of the neighbor. They install Trans and willing to do a "Partial" manual J. I think at this point as long as they got good reference it's fine. I been calling around some vendor wont even do it. Or just show up saying they would do the calc, but doesn't.
like many what you guys suggested, look for the install than look at the product. :-) learning the hard way.
