LRS U... Ultra-igh fficiency ommercial Water eaters
Ultra-igh fficiency Water eaters from Laars eating Systems ompany Laars U... is one of the most exceptional additions to the Laars eating Systems commercial lineup. Utilizing exclusive designs and technologies, the new Laars U... outperforms the competition when it comes to installation flexibility, quiet operation and, most importantly, efficiency. First and foremost, Laars U... has a remarkable thermal efficiency rating as high as 99.% an unprecedented statistic that makes this line of commercial water heaters the most efficient in its class. In addition to this remarkable performance, Laars U... is second-to-none in installation flexibility. ll models can vent vertically, horizontally and are also approved for unbalanced, direct-vent closed combustion applications. The unbalanced aspect means the air intake pipe doesn t have to be vented the same distance as the exhaust a feature not available on competitors models (net vent lengths up to 0 equivalent feet using " S, P or P piping or 70 equivalent feet using " S, P or P piping). Laars U... is also noticeably more quiet than any other water heater in its class, and building owners, managers and occupants will appreciate the difference. Last but not least, Laars U... line comes with Laars eating Systems patented stainless steel Sediment Reduction System, a continuous self-cleaning system that is proven to extend the life of the water heater. With its superb efficiency, unprecedented installation flexibility and quiet operation, Laars U... gives building owners, engineers and plumbing and heating professionals a commercial water heater that meets the demands for large amounts of hot water, saves energy and is installable in some of the most difficult locations. There s no doubt that Laars U... is the best line of highefficiency commercial gas water heaters available in the industry.

LRS U... ULTR-I FFIINY WTR TRS Laars U... Standard quipment Features: Thermal fficiency up to 99.% Fully condensing design. Three Pass Flue System The three pass flue system keeps the hot combustion gases moving at a high velocity. The combination of high turbulence and velocity causes an enormous rate of heat transfer into the water. Factory Installed Sediment Reduction System old inlet sediment reduction device made of stainless steel for increased durability. elps prevent sediment build-up in tank. lass-lined Tank Laars eating Systems water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. Our high silica lining provides a tough interior surface. Protective Magnesium node Rods mployed to provide an extra measure of corrosion protection for longer life. ach Laars U... heater has anodes, except the U-00T-99 which has powered anode rods and one non-powered anode rod. Low NOx Premix Power urner eveloped for the Laars U..., a turbulent flame shoots down the submerged combustion chamber. This turbulence causes a thorough mixing of the gas and air for optimum combustion and high heat transfer efficiencies. Far exceeds alifornia emission requirements. Submerged ombustion hamber Submerging the combustion chamber in the center of the water storage tank minimizes radiant heat loss and improves efficiency. lectronic ontrols djustable electronic thermostat for control between 80 F and 80 F. The recycling nergy ut Off (O) shuts off all gas flow in an event of an overheat condition. Zero Inch learance The Laars U... jacket is cool to the touch and is approved for zero inch clearance to combustibles for unsurpassed installation flexibility. Factory Installed ielectric Fittings ll heaters equipped with special water heater nipples for longer heater life. No special dielectric fittings to buy. Non-F Foam Insulation Surrounds the tank surface, saving energy by retarding loss of heat. Flexible enting The Laars U... can vent vertically or horizontally with either " or " P, P or S vent pipe, and is approved for direct vent closed combustion applications, or those applications that require inside air for combustion. Foam core pipe is permitted on the entire venting system.
