But I don't recall ever being shown where the water heater was located, for example.
The water heater has access outside somewhere which will correspond inside. You may have to unscrew a panel to get to it though.
All of the manuals a very generic. Most all of your appliances & other items will have manuals online if you look up particular models.
As for schematics of any kind, forget it. They change floorplans too often to ever keep up with that stuff.
