One of the companies we represent was owned by Russ Geaslen. He changed the boiler industry as we know it by designing and patenting the primary/secondary piping of modular boilers in 1964 (Patent No. US3329343A). Russ was half genius and half mad scientist. Unfortunately, he passed on to the big boiler room in the sky in 1996. I still miss him.
If you are like most designers or installers, I would wager that you have never read the installation manual for the piece of equipment that you design or install. And if you do not, you may be held responsible for any omissions recommended in that manual but not implemented.
