MODULATING BURNER ADVANCES THE CYCLONE TO HIGHER LEVELS OF EFFICIENCY
The full line of A. O. Smith Cyclone Mxi condensing water heaters has been designed to provide
years of dependable service and feature industry leading technology. Models are available from
120,000 to 500,000 Btu/h and all deliver thermal efficiencies of 95% and higher. The unique helical
coil heat exchanger limits weld joints for optimal service life while maximizing heat transfer.
Cyclone is the industry leader in high efficiency commercial water heating. The current Mxi
modulating models adjust firing rate to the specific demand further increasing efficiency and
money savings.

SUBMERGED COMBUSTION CHAMBER,
WITH HELICAL HEAT EXCHANGER COIL
• Positioned in center of tank, surrounded by
water to virtually eliminate radiant heat loss
from chamber
• Direct spark ignition
• Spiral heat exchanger keeps hot burner gases
swirling, uses centrifugal force to maximize
efficiency of heat transfer to water in tank
• Spiral heat exchanger reduces lime scale
from forming on water-side surfaces, which
maintains energy efficiency over time
POWERED ANODES STANDARD ON ALL
MODELS
• Provides long-lasting tank protection in varying
water conditions
• Powered anodes are non-sacrificial
• Automatically adjusts output needed to
properly protect the tank
PERMAGLAS

ULTRA COAT
™
GLASS
LINING
• Glass coating is applied using a liquid slush
coating technique to ensure uniform coating
• Heat exchanger coil is glassed both externally
and internally for optimum protection
MECHANICAL VENTING VERSATILITY
• Conventional power venting or direct venting
• Vents vertically or through a sidewall
• Front located exhaust and condensate
connections allow for easy install and access
• Vents with low cost PVC Schedule 40 intake
and exhaust pipe. Approved for optional CPVC
Schedule 40, Polypropylene and AL29-4C
stainless steel vent materials
• Direct-vent intake and exhaust pipe can
terminate separately outside building or
through single opening, using concentric vent
assembly
• Canadian installations require ULC S636 PVC/
CPVC, ULC S636 Polypropylene and AL29-4C
stainless steel pipe for intake and exhaust
HIGH EFFICIENCY MODULATING
PRE-MIX POWERED BURNER
• Down-fired pre-mix burner provides optimum
efficiency and quiet operation
