|A major design initiative
In keeping with our commitment to continuous product improvement, A.O. Smith's engineering group has developed an innovative new design for our gas residential water heaters. Our new C3 TechnologyT gas water heaters feature a new sealed combustion chamber and a new flame arrester component and are covered by four U.S. patents.
A.O. Smith C3 TechnologyT gas water heaters will meet new standards and testing protocols established by the American National Standards Institute (ANSI) that deal with the accidental or unintended ignition of flammable vapors, such as those emitted by gasoline. By July 1, 2005, the new ANSI Z21.10.1 standard will cover virtually all gas-fired residential water heaters manufactured in the United States with BTU inputs of 75,000 or less. A.O. Smith residential water heaters will meet the new ANSI standards in accordance with the schedule above.

|Quality performance from the water
Our new C3 TechnologyT gas water heaters will meet the new ANSI standards and will continue to deliver the same outstanding quality and performance you have come to expect from our products.
Start-up will be easier, too. All new C3 TechnologyT gas water heaters come equipped with a sight glass and an easy-to-light piezo ignitor, a convenient advancement compared with traditional gas water heaters. Installation procedures, including placement of the unit, gas piping, water piping and venting, will remain the same, with few exceptions.
