KNIGHT is recognized for its reliable,proven performance and high quality standards.Its award winning design assures contractors
and home owners peace of mind and lon�term savings in operating costs.
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.
