T&P Valve if ordered from factory.
A. O. Smith FVIR design meets the American National Standards Institute standards
(ANSI Z21.10.1 - CSA 4.1) that deal with the accidental or unintended ignition of
flammable vapors, such as those emitted by gasoline.
Feature a sealed combustion chamber with air intake filter and a flame arrestor built
into the water heater base. In addition, a thermal cutoff (TCO) device, is designed
to shut off gas flow to the burner and pilot if poor combustion is detected.
