Description: Built from the foundation of the KN-Series, this enhanced line incorporates all of the standard features of its predecessor, coupled with increased efficiencies. Providing thermal efficiency ratings that meet or exceed federal and state requirements for performance and/or rebate incentives, the boilers are suited for green building initiatives and LEED projects. They utilize a hydrophobic-coated, finned stainless steel heat exchanger to work in concert with the existing high-efficiency cast-iron heat exchanger. The line consists of full variable-flow water-side condensing boilers, allowing easy integration into variable flow primary boiler systems. It is also certified for use with PVC and polypropylene vent materials.
