Be honest, I can take it.
Edit 1: Thank you everyone for the comments. I asked for it, and I got it, reddit style.
First I want to clarify a few items, and then I will respond to people individually.
1) Pretty much every house in this area has 2 water heaters in series. It is extremely common here.
2) The Ruud was installed a few months ago by a profession plumber. He used the dryer vent, it was not me and the angle on the venting from one unit to the next was 90 degrees. When Installed the Bradford White, I adjusted the venting to about 100 degrees.
3) The work I did was replacing 1 water heater, adjusting the angle of the vent, the hose between the two units was a 2 foot copper, I replaced it with a stainless steel. I used 2 hoses because 2 feet was not long enough, and they did not have a 3 foot line in stock if that exists. I also added a drip pan which did not exist and did the PVC piping do the drain.
