The Fogatti RV Tankless Water Heater # LSB44FR requires 12v DC power to operate. A lot of older water heaters run off of 110v AC power so when people replace them without knowing this they end up sending way too much power to the unit and blow the fuse. If this is the case for you then you'll need to run new power and ground wires to either the battery or DC distribution panel in your RV. If this isn't the case then you'll still want to check your wiring and look for any shorts or loose connections.
