This extends your coverage for your KNG199ICW beyond the original warranty period, but also adds any cost of labor to replace or repair your Kings Peak water heater.

* 150,000 Gallon Stainless Steel Heat Exchanger Warranty available on KNG199ICW/X models only.

**Please note that scale inhibitor cartridges must be replaced every 6 months and only those cartridges supplied by Salt Lake Iron & Steel Ltd. Co. may be used to qualify for the extended warranty plan.  Lack of replacement of the replacement cartridge every 6 months or using another type of scale inhibitor not supplied by Salt Lake Iron & Steel Ltd. Co. immediately voids extended warranty coverage.
