Energy Factor and Average Annual 
Operating Costs based on D.O.E. 
(Department of Energy) test procedures. 
D.O.E. national average fuel rate 
electricity 8.6¢/KWH.
Recovery = wattage/2.42 x temp. rise °F.
Example:
4500W
= 21 GPH
2.42 x 90°
These units are designed to 
meet or exceed ANSI 
(American National Standards 
Institute) requirements and 
have been tested according to 
D.O.E. test procedures and 
meet or exceed the energy efficiency requirements of NAECA, 
ASHRAE standard 90, ICC 
Code and all state energy efficiency performance criteria for 
energy consuming appliances.
Before purchasing this 
appliance, read important 
energy cost and efficiency 
information available from 
your supplier.
Direct Immersion 
Resistored Element
Transmits all the heat directly to the 
water, so efficiency is maximized. 
Element screws in and out for easy 
replacement.
Nickel chromium heating coil imbedded 
in magnesium oxide and sealed in a 
copper tube. Although in direct contact 
with water, the ends are sealed to 
prevent entrance of moisture. Elements 
are easily changed should the need arise 
by screwing into special tank flanges. 
Operates silently 
with maximum 
efficiency. 
Patented 
resistor element 
helps prolong tank 
and element life.
