WALL MOUNT BOILER
THE SMARTEST CHOICE FOR',CON'DENSING BOILER PERFORMANCE
The KNIGHT"'Wall Mount,'engineered with,Loch`invar'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 orAL29-4C 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 to3.2 million Btu/hr heating capacity.
The new KNIGHT Wyall Mount Boiler reflects Lochinvar's constant commitment to providing all the
options you need to serve every application.

The Squire Stainless Steel Indirect Water Heater--with 12 models to choose

Squire features important enhancements that our customers will recognize and
benefit from such as a welded and passivated stainless steel tank and heat

$ Laser Cut Precision
A CNC laser uses Programmable Logic Controls to precisely cut the Squire Indirect Water
Heater's tank shell out of 14 gauge 316L stainless steel to a tolerance of.01 inch.
Tan k Cylinder Roller
The computer controlled tank cylinder rolling machine ensures that the 316L stainless
steel is transformed into a geometrically perfect cylinder.
Colt Winder
Straight tubes are rolled by a seven axis coil winder and turned into a precise,round

potable water stored in the tank.
Robotic Welder
This state of the art six axis programmable robotic welder uses computer guidance to
accurately weld all of the stainless steel fittings and coil to the stainless steel tank.
Hydrostatic Leak Vest
After it leaves the robotic welderthe tank is hydrostatically pressure tested to ensure
quality conformance.
Passivation Process
Each tank is subjected to a soaking spray of
nitric acid.This treatment washes away any
i iron that was left behind during the welding
process and re-establishes the oxide level ofthe
stainless steel to ensure corrosion resistance.

The dent resistant polypropylene jacket and f
