*Installation
1. This tank must be installed according to your local plumbing code. It should be
at least 18 from the cold water inlet to the water heater...*
It looks like an Amtrol and they do not have that requirement and the unit manufactured by Watts does not have that requirement either. They just need to be installed on the cold water side between the water heater and backflow device.
