• 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.
• Special Wiring Options – A limited number of special wiring options are available. Consult factory for price and availability.
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 effi-
ciency requirements of NAECA,
ASHRAE standard 90, ICC
Code and all state energy effi-
ciency 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.
