Uniform Energy Factor and rated gallon capacity based on Department of Energy (DOE) requirements.
++System Sentinel optional. Add EC1 to the end of the model number. System Sentinel not available on single element models, available on dual element models only. System Sentinel not available in excess of 5 kW on 208 V models.
*Insulation blanket(s) required to achieve UEF value. Water heater dimensions prior to installing insulation blanket(s). Blanket(s) will be included with water heater. The blanket(s) add 2-1/2 inches to the tank height and 10 inches to tank diameter.
**Insulation blanket(s) required to achieve UEF value. Water heater dimensions prior to installing insulation blanket(s). Blanket(s) will be included with water heater. The blanket(s) add 2 inches to the tank height and 4 inches to tank diameter.
- Heaters furnished with standard 240 volt AC, single phase non-simultaneous wiring, and 4500 watt upper and lower heating elements.
- If heating elements of different wattages than those shown are demanded by zone requirements, they must be specifically requested.
- Single element models available on special order (6000W max.). Substitute "1" for "2" in model number.
- Special Wiring Options - A limited number of special wiring options are available. Consult factory for price and availability.
- All models equipped with heat traps.
+Recovery = wattage/2.42 x temp. rise °F. Example: 4500W / 2.42 x 90° = 21 GPH
+Recovery calculations used are based on 4500 watt elements used in non-simultaneous operation.
