STANDARD FEATURES
GLASS-LINED TANK — Tank interior is coated with glass
specially developed for use in water heaters. Tanks rated at
125 psi working pressure; 150 psi or 160 psi working pressure
is optional. Vermin proof fiber glass insulation reduces costly
heat loss. Constructed to Section IV of ASME code, and UL
standards. Tanks have channel skid base. A 4" x 6" handhole
is furnished on 500, 600 and 700 gallon models; 11" x 15"
manhole is furnished on 800 gallon and larger sizes.
INCOLOY IMMERSION HEATERS — Heavy-duty medium watt
density elements (three/immersion heater) have incoloy
sheathing: provide excellent protection against oxidation and
scaling. The input ranges from 15KW to 3000KW (see
accompanying chart).
AVAILABLE WITH OPTIONAL GOLDENROD ELEMENTS —
All models are available with the Goldenrod 24K gold plated
elements (patent pending). Goldenrod Elements provide long-
life and five times the scaling resistance of standard incoloy
elements. Goldenrod Elements carry a three-year warranty
against failure due to scale.
FUSING — Control and power circuit fusing to meet N.E.C.
PILOT SWITCH AND LIGHT — Provided on front of heater;
permits manual starting and stopping of heater by interrupting
power to control circuit.
MAGNETIC CONTACTOR(S) — Heavy duty UL rated for
100,000 cycles.
LOW WATER CUTOFF — Probe type electric low water cutoff
prevents energizing of elements in the event of low water
condition.
120 VOLT CONTROL CIRCUIT — 120 volt control circuit is
powered by fused transformer.
IMMERSION THERMOSTAT — Immersion temperature control
(one per 60KW) is adjustable to 180°F; high temperature cutoff
is manual reset, adjustable type.
