Features and Benefits N/A 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 N/A Efficiency
All models tested according to ANSI test procedures, and meet or exceed the thermal efficiency and standby loss requirements of ASHRAE standard (EPact). Also exceeds energy efficiency codes of all states including California Energy Commission (CEC).

Safety and Construction
Design certified by CSA: For operation at 180 degrees; meets all safety and construction requirement of ANSI Z21.10.3; as an automatic storage or instantaneous water heater; as an automatic circulating tank water heater; and for operation on combustible floors and in alcove installations. Certified for 150 PSI maximum working pressure (160 PSI for ASME models).

Optional Construction
ASME construction is available on designated models. UL Sanitation (NSF5) compliant models are available when equipped with optional seal kit (Part No. AM35450).

CSA/ASME Rated T&P Valve
Factory installed relief valve

Insulation
Sag and moisture proof fiberglass insulation surrounds the storage tank and heavy mineral wool insulation surrounds the combustion chamber.

Hand-hole Cleanout
For easy removal of lime/sediment deposits.

Manual Reset High Limit
ASME models are factory equipped with manual reset high limit to meet the code requirements in many states.

Gas Control System
Thermostat adjusts from 100 to 180 degrees Fahrenheit, 24 volt combination gas valve includes main gas pressure regulation, on-off manual valve, 120/24 volt transformer and high limit temperature cut-out.
Warranty N/A
  • 3-Year limited Tank Warranty. Commercial Warranty Certificate for Complete Information.
Note N/A All Models Require a 120 V Power Source/0.3 amps
