KN-Series commercial, gas-fired boilers (including the KN-6, KN-10 and KN-20), with a self-adaptive design tolerant to changing conditions are suited for use in applications with water source heat pumps. The new KN Series boilers combine the high efficiency and small footprint of modern copper boilers with the long-life of cast iron boilers. All KN-Series boilers feature Tru-Flow™ technology to control the air fuel mixture at all firing rates and venting conditions. User-friendly controls provide multi-function monitoring of all operating modes with text display and intuitive diagnostics. The control is also compatible with building automation systems.
