You need to winterize the entire water system and not just the Girard Tankless Water Heater.
I typically hook up my compressor to then city water port and then open the hot and cold at each fixture one at a time to blow the water out of all the lines. That is usually good enough in a pinch.
Since I store my coach in PA while I am in FL 8 months out of the year, I will also pump RV antifreeze through the lines..... just to be safe.
