A pocket-sized reference manual is available for the Guardian System™, a new line of residential, gas-fired atmospheric water heaters that are designed to meet the American National Standards Institute (ANSI) standard on flammable vapor ignition resistant (FVIR) water heaters. The 32-page “Rheem Guardian System Guide Book” provides a brief overview of this new ANSI standard. Features and benefits of the Guardian System’s key components are reviewed. A cutaway is labeled with the key components. According to the company, two cross-reference charts list the model numbers for its Fury and Professional models to make it easier for installers to make the switch to the Guardian System. The last two chapters discuss some service and repair issues and answer some FAQs about FVIR.
