The two options are: 1) Replace it with the same shell (Kit 24201-6). (CARBON STEEL SHELLS THAT FAIL UNDER WARRANTY WILL BE PROCESSED USING OPTION 1). 2) Replace it with a complete Hydro assembly KC heater with stainless steel shell (24201-4). When going with this option, the customer must also purchase the hot water outlet stainless steel flex connector (P/N 97044, see page PP100.2) and reconfigure their piping to accommodate this flex connector.
