Perfect fit: A. O. Smith introduces Master-Fit ultra-low NOx commercial gas water heater


Ashland City, Tenn.–A. O. Smith (, the leading innovator in water heater technology, has introduced a commercial water heater that combines compact, easy-to-install size with low nitrous oxide emission technology. The Master-Fit Ultra-Low NOx Commercial Gas Water Heater, the shortest commercial water heater in its class, is for sale in California markets only.

“With the shortest design on the market, multiple water connections and ultra-low NOx construction, the Master-Fit Ultra-Low NOx Commercial Gas Water Heater was developed to deliver top-performance in demanding commercial gas applications while focusing on simple installation, especially where height is restricted,” said David Chisolm, vice president of marketing. “Innovative engineering also increased the accuracy and dependability of the control system, reduced excess heat from the burner, and improved the unit’s overall reliability and longevity.”

The easy-to-install Master-Fit series 200 includes two models: the 81-gallon BTL-198 at 65-inches tall and the 93-gallon BTL-199 at 73 inches tall. The series features ultra-low NOx assembly to keep business owners from worrying about emissions rules and multiple components designed to keep costs low.
