Helpful Information

The KNIGHT Wall Mount, engineered with Lochinvar’s exclusive SMART SYSTEM control and an array of other innovative features is far ahead of any heating boiler in its class. It promises and delivers ultimate ease of installation and maintenance. With up to 99% thermal efficiency, low-NOx emissions and a fully modulating burner, it is the best ”green choice” for today’s environmentally focused market.

Seven modulating/condensing stainless steel KNIGHT Wall Mount boilers are available with 55,000–399,999 Btu/hr inputs in a space-saving wall-mounted design. All are equipped for direct-vent installation with air intake and exhaust runs up to 100 feet using PVC, CPVC, Polypropylene or AL29-4C vent materials. This range of choices is ideal for residential or light-duty applications such as small hotels, schools and office buildings. For higher-demand applications, up to eight KNIGHT Wall Mount units can be installed utilizing the built-in cascading sequencer to deliver up to 3.2 million Btu/hr heating capacity.
