Flammable Vapor Ignition Resistant (FVIR) Compliant Design

Meets 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.

Covered by four U.S. patents, FVIR Compliant 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.

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.
