The Best You Can Buy Is

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 long term savings in operating costs.

Now, Lochinvar has raised the KNIGHT standard to even greater heights. The dramatically enhanced SMART SYSTEM™ control with
color display gives installers and maintenance personnel a greater level of control than ever before. It's easier to access all the
information they need to setup, troubleshoot and monitor all boiler functions. Additionally, two new cascading options allow the
installer to fine-tune sequencing of multiple boiler installations.

More than ever, KNIGHT is the best choice for traditional hydronic space heating, radiant floor heating and domestic hot

water applications.
