IMMERSION ELECTRIC TANK-TYPE WATER HEATERS
6 KW THRU 54 KW
RHEEM-RUUD Electric Commercial Water Heaters are
suitable for general commercial hot water applications
and are also ideal for point-of-use installations, eliminat-
ing costly temperature loss in long piping runs. A single
50, 85 AND
unit can be used as a booster heater to satisfy the hot
120 GALLON
water requirements of commercial dishwashers. A single
CAPACITIES
temperature storage unit, when installed with a mixing
valve, will supply two temperatures in food service
208, 240
establishments. For larger volume hot water
AND 600
requirements, 2, 3 or 4 units can be parallel
VOLTAGES
manifolded, using optional factory kits.

SYSTEM SENTINEL – An element diagnostic
panel, utilizing light emitting diodes (L.E.D.) correspond-
ing to the number and location of each heating element
are energized when the electric elements are operating.
An unlit L.E.D. pinpoints the exact location of a non-
functioning element, making element operation
diagnosis simple and positive..
R-FOAM® INSULATION – A rigid ployurethane
foam insulation provides superior insulating qualities,
improves efficiency. Exceeds R-16 insulation factor. Our
patented process of injecting R-Foam directly into the
insulating cavity adds additional durability and toughness
to the heater jacket. Fiberglass insulation guards against
heat loss in the heating element compartment, and
provides easy service access.
LIFEGUARD HEATING ELEMENTS – Separate
screw-in type elements feature a stainless steel outer
sheath of INCO-LOY® 800, surrounding a Nichrome wire
filament, to resist water chemical corrosion and burn-out
even in air or sediment…for long element life and long
life performance. Elements are directly immersed in the
water for efficient transfer of heat, and are easily
WATER CONNECTIONS – Hot outlet and cold inlet
are 1-1/2" NPS brass nipples which prevent excessive
turbulence of heating water and result in optimum tank
draw.
SINGLE PANEL CONTROL BOX – With hinged
door, provides immediate access to all electrical
components and elements.
changed by simply screwing new ones into the tank.
GLASS LINED STORAGE TANK – Heavy duty
steel tank protects with double coating of exclusive
Rheemglas to resist the corrosive action of hot water.
Designed for 150 PSI working pressure. Each tank is
supplied with factory installed anode rods for cathodic
protection.
TERMINAL BLOCK – All models are equipped with
CSA listed terminal blocks for simplicity of installation.
This new terminal block will accept either copper or
aluminum field connect wire.
Certifications and Ratings:
EFFICIENCY – These units have been tested according to procedures specified by CSA and meet or exceed the energy
efficiency requirements of ASHRAE Standard 90.1b 1992 requirements for energy conservation.

The minimum distance to provide
adequate clearance for protection of
combustible material is 0 inches from
jacket and 18 inches from access door.
However, additional clearance for
accessibility to permit inspection and
servicing such as removing heating
elements or checking controls must be
provided. All models are approved for
installation on combustible flooring.

Additional Construction Features:
240 VOLT CONTROL CIRCUIT – all units are
furnished with a 240 volt control circuit. All controls
(thermostats, high temperature limit, etc.) are operated
off of this basic 240 volt control circuit.
ELECTRICAL CONNECTIONS – Prewired,
accessible control box with multiple knock-outs on top
and side in size selections to match the Canadian
Electrical Code. Sizes range from 1/2" to 2".
A grounding screw is provided for attaching an
equipment grounding conductor.
Optional Equipment:
ELEMENT FUSING – In addition to all the above
construction features, on immersion thermostat models
9 KW through 54 KW there is internal fusing available
that protects all elements, magnetic contactors,
thermostats and internal wiring circuits. On immersion
thermostat models 24 KW and above, additional
thermostats are provided so that the maximum element
input will not exceed 18 KW per step. Temperature
differential between steps can be set as desired. On 24
through 36 KW units, two thermostats are provided and
on the 45 and 54 KW units, three thermostats are
provided.
STANDARD EQUIPMENT ASME T&P
VALVE – This is a double safety valve that relieves
when temperature or pressure becomes excessive.
AUTOMATIC TEMPERATURE CONTROL –
Water temperature settings from OFF and ranging from
90°F up to 180°F (32°C to 82°C) are maintained by
immersion thermostat that insures instant shut off at
the selected temperature for safety and economy of
operation. One thermostat is supplied as standard. For
element steps, up to two additional thermostats can
be supplied – see optional controls. Over temperature
protection is provided by an immersed high temperature
limit control, factory set at 200°F (93°C).
For optional fusing, suffix “F” should be added to the
model number. Ex. EG120CF-45KW.
MAGNETIC CONTACTORS – All models
equipped with contactors, factory wired for simplicity of
installation and economical maintenance throughout life
of the unit.
