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% 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.
The KNIGHT Wall Mount Boiler reflects Lochinvar’s constant commitment to providing all the options you need to serve every application.
Advanced Negative Regulation Technology
KNIGHT safely and reliably operates with supply gas pressure as low as 4 inches water column.
Negative Regulation (Neg/Reg) technology automatically adjusts fan speed to ensure the correct volume
and mix of fuel and air throughout the firing range.
Fire Tube Design
This fully welded ASME Certified stainless steel heat exchanger uses oval shaped tubes to pass heat from the products
of combustion into the water stored in the vessel. To facilitate heat transfer the tubes are manufactured with dimples
to slow the flue products and extract available latent energy. With a fire tube design the flue products are inside
tapered passage ways and the water is passed through the vessel. Since the flue products pass through tubes
and the water is circulated through a larger diameter vessel a fire tube design allows for minimal head pressure
loss through the boiler which allows the boiler to be installed easily into various hydronic applications.
Water-Backed Combustion Chamber
An outstanding feature of the fire tube design is a water backed combustion chamber. By having the combustion
chamber surrounded by water the Knight Wall Mount has more heating surface area. This larger heating surface
area allows for efficiencies up to 99%.
Fully Modulating Burner
The SMART SYSTEM allows fully modulating combustion with 5:1 turndown. The burner can fire as low as 20%
of maximum input and modulates the firing rate up to 100% as demand increases. The burner is a single
stainless steel assembly covered with woven steel mesh and fires in a 360° pattern along the entire length
of the burner. This allows the compact KNIGHT to exceed the modulation capacities of units with larger
multiple burners.
The Smartest Choice for
Condensing Boiler Performance
KNIGHT offers 5 venting options and tremendous flexibility for placement of units within the building, because it permits direct-vent air
intake and exhaust runs up to 100 equivalent feet using either PVC, CPVC, Polypropylene or AL29-4C stainless steel vent pipe.
