Recovery capacities at 100°F rise equal: for non-simultaneous element operation = 4.1 gal. x KW of one element; for
simultaneous element operation = 4.1 gal. x 2/3 KW of both elements. For other rises multiply element KW as
previously explained by 410 and divide by temperature rise. Full load current for single phase = total watts + voltage.
The water heater(s) shall be Dura-Power Model(s) No. ____________ as manufactured by A. O. SMITH or an approved equal. Heater(s) shall be rated
at _____ KW, _____ volts, _____ phase, 60 cycle AC, and listed by Underwriters' Laboratories. Tank(s) shall be _____ gallon capacity. Heater(s) shall
have 150 psi (1034 kPa) working pressure and be equipped with extruded high density anode rod. All internal surfaces of the heater(s) exposed to
water shall be glass-lined with an alkaline borosilicate composition that has been fused to steel by firing at a temperature range of 1600°F (870°C).
Electric heating elements shall be medium watt density with zinc plated copper sheath. Each element shall be controlled by an individually mounted
thermostat and high temperature cutoff switch. The outer jacket shall be of baked enamel finish and shall be provided with full size control
compartment for performance of service and maintenance through hinged front panels and shall enclose the tank with foam insulation. Electrical
junction box with heavy duty terminal block shall be provided (except on 120V & 277V [no junction box on DEL-6 thru 20]). The drain valve shall be
located in the front for ease of servicing. Heater tank shall have a three year limited warranty as outlined in the written warranty. Fully illustrated
instruction manual to be included.
