Construction Features
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 or cathodic protection.
WATER CONNECTIONS – Hot outlet and
cold inlet are 1-1/2" NPS brass nipples which pre-
vent excessive turbulence of heated water and
result in optimum tank draw.
R-FOAM
®
INSULATION – A rigid
polyurethane foam insulation provides superior
insulating qualities and improves efficiency.
Exceeds R-16 insulation factor. Our patented
process of injecting R-Foam directly into the insu-
lating cavity adds additional durability and tough-
ness to the heater jacket. Fiberglass insulation
guards against heat loss in the heating element
compartment, and provides easy service access.
SINGLE PANEL CONTROL BOX – With
hinged door, provides immediate access to all
electrical components and elements.
HEATING ELEMENTS – Separate screw-in
type LIFEGUARD
®
elements on 50, 85 and 120
gallon models 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 changed
by simply screwing new ones into the tank.
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.
ELECTRICAL CONNECTIONS – Pre-wired,
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.
AUTOMATIC TEMPERATURE
CONTROL – Temperature is maintained by a
surface mounted thermostat adjustable to provide
water 120°F to 160°F (50°C to 71°C) that insure
instant shut off at the selected temperature for
safety and economy of operation. Over tempera-
ture protection is provided by surface mounted
high temperature limit controls, one per heating
element, factory set at 190°F (88°C).
STANDARD EQUIPMENT ASME T&P
RELIEF VALVE – This is a double safety valve
that relieves when temperature or pressure
becomes excessive.
