Product Overview

ALWAYS LEADING THE CHARGE
Lochinvar’s KNIGHT XL
®
has earned a reputation for reliability starting with its initial launch in
2005. Its workhorse heat exchanger performed with little need for service making it a go-to
choice for many contractors. Because of Lochinvar’s commitment to new product development,
any opportunity to make a good product better is always taken. In 2010, the KNIGHT XL’s SMART
SYSTEM
™
was given an upgrade making setup and programming even easier than before. As the
timeline continues, the boiler now has a new sleek appearance and a multitude of refinements
sure to keep current fans and win over even more.
With years of proven experience, the KNIGHT XL expands on its already tried and true feature
set. Making hard work look easy, this commercial boiler steps out front. Available in five models
ranging from 399,000 to 999,000 Btu/hr, the advanced units feature 97% thermal efficiency and
10:1 turndown.
Line these boilers up side by side in any new construction or retrofit because zero side clearances
make maximizing available footprints a snap. All the utility connections are located in the back
of the units including vent, which can extend up to 150 feet for both intake and exhaust.
Set-up KNIGHT XL quickly and accurately using the SMART TOUCH
™
control. The LED touch screen
display clearly leads technicians through features like Ramp Delay and controlling the 0-10 volt
pump. And with CON·X·US
®
remote connect being standard, making adjustments remotely are
easy from any wireless device.
