There are 2 things you can do to prevent the Girard 2GWHAM Tankless RV Water Heater - 42000 BTU from freezing. If you leave the unit on with power and propane to it, the winter protection device will turn the unit on automatically every time there is an ambient temperature of about 35 degrees. You can also run anti freeze thru the lines from your water pump. The unit does not have a drain.
