Are all FVIR water heaters the same?
No, they are not. The consortium of manufactures agreed on flame arrestor plate technology to create the new generation of FVIR water heaters. Early in the development, Rheem researchers at their Montgomery labs discovered that flame arrestor plate designs might be vulnerable to the effects of lint, dust and oil – LDO. Rheem urged the ANSI standards be reviewed. As a result, the ANSI standard now includes testing for reliability in LDO environments. Throughout development, Rheem engineers have been highly attentive to the role LDO robustness will play on product reliability and consumer satisfaction.
