Multi Flue

These 80% efficient models have been offered since the mid-1980’s, and other than updated controls, they have remained virtually unchanged for decades. Training for multi-flue commercial water heaters is available online or at A. O. Smith University’s hands-on lab in Ashland City (Nashville), Tennessee.

In order to attend the hands-on lab, you must first watch the three online Basic Commercial Gas Water Heater videos and pass a short test. For more information about classes in our hands-on lab with live equipment, click here.
