Description
The NEW Suburban 5240A RV Water Heater SW6DEL is a high-performance 6-gallon dual-fuel water heater designed to operate on propane and/or 120V AC electric power, providing reliable and efficient hot water for RV applications. Built with a porcelain-lined steel tank and protected by an anode rod, this unit delivers excellent corrosion resistance and long service life.
The SW6DEL features 12V Direct Spark Ignition (DSI), eliminating the need for a standing pilot light and allowing for convenient, push-button operation from inside the RV. Its dual-switch control enables operation on propane, electric, or both simultaneously for faster recovery times and flexible energy use.
Engineered to fit standard Suburban cut-outs, the Suburban 5240A SW6DEL is ideal for replacing or upgrading older RV water heaters while maintaining factory compatibility and performance.
