Cyclone Xi Water Heater

UP TO 96% THERMAL EFFICIENCY, DIRECT VENT
FEATURES:
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 shaped heat exchanger reduces the accumulation of lime scale; maintains higher efficiency performance over time.

POWERED ANODES STANDARD ON ALL MODELS

• Provides long-lasting tank protection in varying water conditions
• Anodes are of a permanent design and do not require replacement unless damaged

PERMAGLAS ULTRA COAT GLASSLINING

• 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 power- 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. Canadian installations require ULC S636 listed PVC or CPVC pipe for intake and exhaust.

HIGH EFFICIENCY PRE-MIX POWERED BURNER

• Down-fired pre-mix burner provides optimum efficiency and quiet operation
• Top-mounted radial burner design ensures optimum combustion efficiency
