NOTES:
Heat ratings are for natural gas heat exchangers operated at or below 2000 ft(610 m). For information on propane or alti-
S tudes above 2000 ft(610 m),see the Application Data section of this book.Accessory Propane/High Altitude kits are also
g available.
In the USA the input rating for altitudes above 2000 ft(61 Urn)must be derated by 4%for each 1000 ft(305 m)above sea
level. In Canada,the input rating must be derated by 10%for altitudes of 2000 ft(610 m)to 4500 ft(1372 m)above sea level.

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.0.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 BTX-
surface than standard straight flue tube
• Produces 90%thermal efficiency,which saves money on operating costs, ,
increases hot water output compared to standard efficiencywater heaters
p P '' - ,.
•
• 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 'f', . j
S636 listed PVC or CPVC pipe for venting.
• 2"pipe,vents up to 45 equivalent feet '. ' �
• 3"pipe,vents up to 128 equivalent feet
• 4" pipe,vents up to 128 equivalent feet 5

• Equipped with 120 volt,60 Hz electrical system(rating 5 amps or less),6-foot cord with
standard 3-prong connector z '°
• 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 ..4,r
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 Y;`d,"

• Total height is 70-5/8"to top of unit '" ,
SIDE-MOUNTED HOT AND COLD RECIRCULATING TAPS =
