Neil it appears Kentucky follows the IRC/IPC so here you go.
@mwilles you may want to explain further how to properly support the tank. I call this out often. I recommend the tank be secured or strapped and not dependent upon piping. Is there a specific methodology for securing the tank?
Brian this is a photograph of a tank support device. This is the photograph I use in my reports. I hope this helps.
I see it quite a lot here on larger homes…Now, is it ok to refer to the second unit as a “Hot Water Heater”???
Thank you Martin
