Resistant (FVIR) Water Heaters

A. O. Smith FVIR design meets or exceeds 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.

COLD CONNECTION

(LBS)

VALVE

1/2" GAS CONNECTION

If ﬂammable vapors accidentally enter the combustion chamber, the arrestor is designed so ﬂames burn off the top surface and cannot escape down through the arrestor.

A. Industry standard Thermopile B. Large View Port for easy burner inspection C. 360° Combustion Air Filter D. Thermal Cutoff (TCO) with manual reset
