WALL MOUNT BOILER
THE SMARTEST CHOICE FOR CONDENSING BOILER PERFORMANCE
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 aspace-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.
11111016
The new KNIGHT Wall Mount Boiler reflects Lochinvar's constant commitment to providing all the
I options you need to serve every application.
' ADVANCED NEGATIVE REGULATION TECHNOLOGY

with dimples ra stow LIIe flue products and extract available latent energy.With a fire tube design the flue products

pressure loss ihmugh the boiler which 3tlow5 the boiler to be installed easily into various hydropic applications.
1 � WATER-BACKED COMBUSTION CHAMBER
1 An outstanding feature of the fire tube design is a water backed combustion)chamber. By having the combustion
I rhamber surrounded by water the (Knight Wall Mount has mace heating surface area.This large{heating surface

- t 1 ;,11 the SMART SYSTEM allows fully modulating combustion with `a:1 turndown_The homer ran fire as low a5
20%of Maximum input and modulates the Bring rate up to 100%as demand increases, The burner is a
single stainless steel assembly covered with woven steel mesh and fires in a 350°pattern along the
entire length of the burner. This allows the compact KNIGHT to exceed the modulation capacities of units
with larger multiple burners.
DIRECT VENTING UP TO 100 FEET Optional Sidewall Vent I
Termination Kit Available
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. '
