A.O. Smith Cyclone Xi ACGSS02407 Specifications

The A.O. Smith Cyclone Xi family of products represents the industry's most technologically
advanced commercial water heaters. The innovative Cyclone Xi design takes performance to
its highest level with efficiencies of 95% and 96%. Models are available from 120,000 BTUs
and now up to 500,000 BTUs. In addition, the Cyclone Xi features an Intelligent Control
System making it the smartest water heater in the industry.
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
• 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
