New Water Heater Standard: Rheem System Goes Beyond
The U.S. water heater industry is implementing a significant product design change that incorporates a new technology — flammable vapor ignition resistance or FVIR — that will help prevent problems caused by improper storage or use of gasoline and other flammable liquids near residential gas-fired water heaters.
As of July 1, 2003, new residential gas-fired units manufactured with storage capacities of 30, 40, or 50 gallons must meet American National Standards Institute (ANSI) standard, ANSI Z21.10.1-2001. (For details on the new standard, see the feature article “Water Heater Design Changes In The Works” in the July 21, 2003 issue of The News.)
