There is a drain plug in the hot water heater. Undo the outside cover and look for a 1/2" npt drain plug in the lower left corner while facing the heater from the outside.
Note: All of this gravity draining of the system will get a lot of water out of the system. Open all faucets to let air in and water out. However, it is not freeze protected yet with just what comes out of a gravity draining. Still need to either blow out the system well with compressed air or run food grade anti freeze (the pink stuff made for RV's) through the system.
Do not forget the outside shower, the toilet flush valve and the pipe traps. Common areas sometimes missed which show up next spring.
Hope this helps
