Corderite Combustion Containment (C3) design meets American National
Standards Institute standards (ANS Z21.10.1 - CSA 4.1 Standards) 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.
Flammable Vapor Ignition
Resistant C3 Technology™
Water Heaters
If flammable vapors
accidentally enter the
combustion chamber,
the Corderite flame
arrestor is designed
so flames burn off
the top surface and
cannot escape down
through the arrestor.
