UniversalInduced Draft commercial gas water heaters are designed for easy installation in applications requiring large quantities of hot water

Features & Benefits

The tighter the commercial retrofit, the more you will appreciate how the Universal’s compact size and multiple  water connections simplify installations.  Choose from 80% thermal efficiency models that range from 250,000-360,000 Btu/h and have maximum temperature setting of 180 degrees Fahrenheit.

Space Saver Design
The short height and narrow jacket diameter, plus the top, front and rear water inlets/outlets offer the ultimate in installation flexibility.

System SentinelLED Diagnostic System 
Our exclusive diagnostic system, with glowing LED lights, verifies system operation sequence by sequence.
