All tankless water heaters have to be installed by a licensed professional that has been trained and certified by the manufacturer of the water heater. Water heater (tankless or tank) installations are not a do it yourself project. Unless you are certified and trained by the manufacturer, you should not install the water heater yourself. Doing so can cause severe harm, injuries and accidents.
