Features and Benefits

Features and 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 98,000-399,900 Btu/h and have maximum temperature setting of 180 degrees Fahrenheit.

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

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

Patented Technology
Universal’s proprietary steel formulation, patented multi-flue design, combined with two coats of porcelain enamel, results in a superior heat exchanger design.

Stainless Steel Burners
Precision burners, raised port design, are formed from high chromium stainless steel. Each burner assembly slides out like a drawer for quick inspection and maintenance.

Low Profile Automatic Flue Damper
Low profile damper minimizes overall product height. Heavy duty vent hood supports are designed to withstand the rigors of installation.

Full-port, Full-flow Drain Valve
Factory installed brass drain valve allows for faster draining and servicing.

Direct Spark-to-Pilot Ignition System
Energy saving ignition that ignites pilot only when there is a call for heat.

Altitude Certifications
Up to 5,000 feet for natural gas and 2,000 feet for LP; with high altitude certification kit, up to 8,000 feet.

Patented Anode Rods
Anode design utilizes multiple magnesium rods to ensure corrosion resistance for a long tank life.

General Information

General Information

 Efficiency
