Lochinvar has raised the KNIGHT standard to even greater heights.The SMART SYSTEMr`"control with color display gives installers and maintenance personnel a greater level of control than ever before. It's easy to access all the information they need to setup, troubleshoot and monitor all boiler functions. Additionally, two cascading options allow the installer to fine-tune sequencing of multiple boiler installations. More than ever, KN/GHT is the best choice for traditional hydronic space heating, radiant�loor heating and indirect domestic hot water applications. f � � NEAT/N6 BO/LER�� All KNIGHT Boilers meet or exceed the moststringent requirements,with less thpn 20ppm NOx.
