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 new 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.

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. A sidewall vent termination kit is
standard equipment with every KNIGHT boiler.

5 Flexible Venting Options
Lead-Lag Cascade
The “lead” boiler modulates with demand to capacity.
As demand increases, additional boilers fire and modulate to
capacity. This continues, with additional boilers firing and
modulating to capacity until all units are operating. Every 24
hours, the SMART SYSTEM automatically shifts the lead boiler
role to the next in the sequence, distributing lead-lag runtimes
equally.
Efficiency Optimized Cascade
This feature optimizes the modulation capabilities of the
Boiler Plant while evenly distributing run time across all
cascaded boilers. Every 24 hours the SMART SYSTEM
automatically shifts the 1st boiler on role to the next in
the sequence, distributing run time equally.
SMART SYSTEM Cascade allows 2 - 8 boilers to be sequenced.
