Cyclone Xi provides outstanding hot water output, with dramatic savings on operating costs compared to units with standard 80% efﬁciency. A.O. Smith’s leading-edge engineering delivers conventional power-vent or sealed combustion power direct-vent versatility, low NOx emissions and excellent space-saving characteristics. Powered anodes, standard on all Cyclone Xi models, provide superior tank protection for years of trouble free operation.

INTELLIGENT CONTROL SYSTEM WITH LCD DISPLAY

•Exclusive A.O. Smith designed control

•Provides detailed water heater status information

•Precise temperature control

•Built-in diagnostics

•Run histrory information

SUBMERGED COMBUSTION CHAMBER,

WITH HELICAL HEAT EXCHANGER COIL

•Positioned in center of tank, surrounded by water to virtually eliminate radiant heat loss from chamber

•Spiral heat exchanger keeps hot burner gases swirling, uses centrifugal force to maximize efﬁciency of heat transfer to water in tank

•Spiral heat exchanger prevents scale and sediment from forming on water-side surface, which can reduce energy efﬁciency over time

POWERED ANODES STANDARD ON ALL MODELS

•Provides long-lasting tank protection in varying water conditions

•Does not require maintenance or inspection

PERMAGLAS® ULTRA COAT™ GLASS LINING

•Exclusive process provides superior protection against corrosion

•Both sides of heat exchanger coil are lined for protection against ﬂue gas condensate inside coil

MECHANICAL VENTING VERSATILITY

•Conventional power-venting or sealed combustion direct venting

•Vents vertically or through sidewall

•Direct-vent intake and exhaust pipe can terminate separately outside building, or through single opening, using concentric vent assembly

•Uses inexpensive PVC, CPVC or ABS pipe for intake and exhaust

HIGH EFFICIENCY PRE-MIX POWERED BURNER

•Down-ﬁred pre-mix burner provides optimum efﬁciency and quiet operation

•Top-mounted burner position prevents condensation from affecting burner operation
