Features and Benefits N/A The tighter the commercial retrofit, the more you will appreciate how this water heater's compact size simplifies installations. Choose from 80% Thermal Efficiency models with inputs of 75,100 BTU/hr and maximum temperature settings of 180 degrees Fahrenheit.

Self-Diagnostic System
Integrated system control for easy installation and service.

Ultra Low NOx Burner
The power assist burner design incorporates stainless steel multi-port burner tubes for long term ultra low NOx performance, less than 14 ng/J. A sight glass allows for burner observation. The entire design is removable and it is highly resistant to the effects of negative air pressure common in modern commercial buildings.

Patented Technology
Proprietary steel formulation with a unique coat of high temperature porcelain enamel to maximize corrosion resistance resulting in a superior tank design.

Patented Anode Rods
Magnesium anode rods are used to ensure corrosion resistance for a long tank life.

Efficiency
Rigid foam insulation provides superior insulating qualities, improves efficiency and reduces operating costs. Our patented process of injecting foam into the insulating cavity adds additional durability.

High Altitude Compliant
All models are certified for applications up to 8,500 feet above sea level.

Full Port, Full Flow Brass Drain Valve
Factory installed brass drain valve allows for faster draining and servicing.

Plus
Side water connections for space heating applications.
Standard replacement parts.
Standard 110-volt electrical connection.
Durable silicon nitride igniter - Hot Surface Ignition (HSI).
Testing and Certifications N/A CSA®/ASME Rated T&P Valve
Factory installed relief valve
Warranty N/A
  • 3-Year Limited Tank Warranty / 1-Year Limited Parts Warranty.
General Information N/A Efficiency
These models have been tested according to DOE test procedures, and meet or exceed the thermal efficiency and standby loss requirements of current ASHRAE standards (Part of the Federally mandated Energy Policy Act (EPact)).
