Commercial Gas Water Heaters
The Cyclone® HE is a light-duty, power vent, fully condensing commercial gas water heater with an internal helical heat exchanger, similar to the design of A. O. Smith’s industry-leading Cyclone® models. This helical heat exchanger helps Cyclone® HE achieve 90% thermal efficiency and deliver outstanding hot water output.
HELICAL INTERNAL HEAT EXCHANGER
Completely surrounded by water in tank, provides much greater heat transfer surface than standard straight flue tube
Operates at 90% thermal efficiency, which saves money on operating costs, increases hot water output compared to standard efficiency water heaters
Minimizes standby losses by trapping heat in the tank
Spiral heat exchanger reduces scale and sediment from forming on water-side surface, which can reduce energy efficiency over time
VERSATILE POWER VENT DESIGN
Vents using inexpensive PVC, CPVC or ABS pipe. Canadian installations require ULC S636 listed PVC or CPVC pipe for venting.
2” pipe, vents up to 20 equivalent feet
3” pipe, vents up to 60 equivalent feet
4” pipe, vents up to 120 equivalent feet
MODULAR BLOWER
Equipped with 120 volt, 60 Hz electrical system (rating 5 amps or less), 6-foot cord with standard 3-prong connector
2” PVC pipe, elbows and condensate drain supplied to connect heat exchanger outlet to blower
PVC Vent Attenuation Assembly (VAA) supplied for applications where extra-quiet operating environment is essential
HIGH OUPUT WITH SMALL FOOTPRINT
22” diameter, combined with 90% efficiency, 50-gallon tank and 76,000 BTU input means Cyclone HE can be installed in less space than a larger 75-gallon unit, with equal or better performance
Total height is 70-5/8” to top of unit
SIDE-MOUNTED HOT AND COLD RECIRCULATING TAPS
Allows Cyclone HE to be installed as part of combination space heating/water heating applications, or any system requiring a recirculating hot water loop
Plugs for the recirculating taps are factory installed
INTELLI-VENT™* GAS CONTROL
Equipped with long lasting silicon nitride hot surface ignitor – no standing pilot
Advanced electronics for more precise control of water temperature and easy-to-understand system diagnostics
180°F maximum temperature setting
PERMAGLAS® ULTRA COAT™ GLASS LINING
A. O. Smith exclusive process provides superior protection against corrosion
Protects all interior tank surfaces including inside and outside of helical heat exchanger
TWO HEAVY-DUTY ANODE RODS
Provides advanced protection against corrosion
GREEN CHOICE® GAS BURNER
Patented “Eco-Friendly” design reduces NOx emissions and meets less than 40 ng/j requirements for low NOx
CSA CERTIFIED AND ASME RATED T&P RELIEF VALVE
MAXIMUM HYDROSTATIC WORKING PRESSURE: 150 PSI
CODES AND STANDARDS
Design-certified by Underwriters’ Laboratories according to ANSI Z21.10.3 - 4.3 CSA standards governing storage-type water heaters
