Rheem Water Heater Universal Gas User Guide

Universal Gas  
Commercial Water Heaters  
Available in Sizes Ranging From 35 - 100 Gallon Tank-Type Models  
98,000 BTU/Hr. thru 400,000 BTU/Hr.  
Universal Gas Commercial Water Heaters are specifically designed to  
minimize the difficulty of replacing failed water heaters and are versatile for  
new installations. These products are designed for applications requiring  
large quantities of hot water.  
Construction Features:  
• Low profile automatic flue  
damper –  
low profile design minimizes over-  
all product height. New heavy duty  
vent hood supports are designed  
to withstand rigors of installation.  
• Universal tank design –  
maximizes installation adaptability  
by offering models with Top, Front  
Side and Rear Side Inlet/Outlet  
water connections.  
• Universal space saver design –  
short heights and small jacket  
diameters result in greater  
installation flexibility.  
• Spark-To-Pilot ignition system –  
standard on all models. Provides  
reliable and energy saving ignition  
sequencing by igniting the pilot  
only when the thermostat calls for  
heat.  
• System SentinelLED  
diagnostic system –  
our exclusive diagnostic system,  
with glowing LED lights, verifies  
system operation sequence by  
sequence.  
• Patented multi-flue tank design –  
proprietary steel formulation,  
patented multi-flue design, and  
two coats of high temperature  
porcelain enamel to maximize  
corrosion resistance result in a  
superior heat exchanger design.

Certifications and Ratings:  
• Efficiency – these models have been tested according to ANSI test  
procedures, and meet or exceed the thermal efficiency and standby loss  
requirements of current ASHRAE standard (Part of the Federally  
mandated Energy Policy Act (EPact)). Also exceeds energy efficiency  
codes of all states including California Energy Commission (CEC).  
• Safety and construction – these products are design certified by the  
CSA: a) For operation at 180°F. b) To meet all safety and construction  
requirements of ANSI Z21.10.3. c) As an automatic storage or instanta-  
neous water heater. d) As an automatic circulating tank water heater.  
e) For operation on combustible floors and in alcove installations.  
All models are North Carolina Code compliant.  
(On Selected  
Models)  
(With Optional  
Leg Kit)  
CERTIFIED FOR A 150 PSI MAXIMUM WORKING PRESSURE  
(160 PSI FOR ASME MODELS).  
• Optional constructions – ASME construction is available on designated  
models. UL Sanitation (NSF5) compliant models are available when  
equipped with optional leg kit. (Part No. AE35450)
