Venting

Proper venting ensures that exhaust gases from your water heater are safely directed outside your home. Several venting configurations are available, each designed to meet specific installation needs. Consult a licensed plumbing professional to ensure you select the correct option for your home.

Glass-Lined Tank

Americans’ glass-lined tanks offer an added layer of protection and efficiency. The glass lining helps retain heat within the tank while shielding the steel exterior from damage.

Anode Rod

Every American glass-lined water heater includes a sacrificial anode rod to extend the tank’s lifespan. The rod generates a mild electrical current that minimizes corrosion through cathodic protection, safeguarding both the glass lining and your water from corrosive elements.

Energy Cut Off (ECO)

Each American water heater includes a built-in Energy Cut-Off (ECO) switch to prevent overheating. While your heater maintains water within a set temperature range, the ECO automatically activates if the temperature rises above safe levels. If overheating occurs, contact a local plumbing professional for assistance.

Temperature and Pressure (T&P) Relief Valve

If water temperature or pressure rises above safe limits, the T&P relief valve opens to release excess pressure and hot water. Because water expands when heated, we recommend using an expansion tank to maintain safe pressure levels. A leaking T&P valve can indicate unsafe conditions—contact a qualified plumbing contractor if this happens.

FVIR (Flammable Vapor Ignition Resistant)

Never store or use gasoline or other flammable vapors near your water heater or any appliance. American residential gas water heaters meet ANSI Standard Z21.10.1 (current edition), helping prevent accidental ignition of flammable vapors, such as those released by gasoline.
