FLAMMABLE VAPOR IGNITION RESISTANT DESIGN

This section will address the changes brought about by the introduction of FVIR compliant products. Other

than items mentioned here, the construction, installation, and service will remain the same as discussed in

the primary handbook.

The FVIR acronym stands for "Flammable Vapor Ignition Resistant." The RELIANCE products are based on

"Corderite Combustion Containment" known as “C3 Technology™” . The C3 Technology design features a

sealed (from non designated air intake openings) combustion chamber and a "flame arrestor" component.

This class of residential gas water heaters meet the new ANSI standards and testing protocols (ANSI

Z21.10.1) established to deal with the accidental or unintended ignition of flammable vapors, such as those

emitted by gasoline. Virtually all gas-fired, atmospherically vented, residential water heaters manufactured

in the United States with BTU ratings of 75,000 or less are required to meet this new ANSI standard

effective July 1,2003. The current implementation schedule for C3 TECHNOLOGY compliant residential

gas-fired products is shown in the following table. These dates are subject to change.
