ANODE ROD* Flammable Vapor Ignition Resistant C3 Technology™ Water Heaters Corderite Combustion Containment (C3) design meets American National Standards Institute standards (ANS Z21.10.1) that deal with the accidental or unintended ignition of flammable vapors, such as those emitted by gasoline. Covered by four U.S. patents, C3 Technology gas water heaters feature a sealed combustion chamber with air intake screen and a fireproof Corderite flame arrestor built into the water heater base. In addition, a thermal cutoff (TCO) device, integral with the thermocouple, is designed to shut off gas flow to the burner and pilot if poor combustion is detected. A If flammable vapors accidentally enter the combustion chamber, the Corderite flame arrestor is designed so flames burn off HOT CONNECTION T&P VALVE 1/2" GAS CONNECTION D E C COLD CONNECTION B A F the top surface and cannot escape down through the arrestor.
