Exhaust Venting Notes

Follow current National Fuel Gas Code requirements for proper installation.

“D” – Typically, same or larger diameter as Draft Hood outlet

“L” – Horizontal piping slopes upward ¼” per foot from heater to chimney or vertical vent

Length of horizontal not more than 75% of “H”

“H” – Not less than 5 feet

Maximize vertical distance to first elbow

FLAMMABLE VAPOR IGNITION RESISTANT (FVIR) 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 State 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.
