It requires a minimum amount of floor space and is designed for extended life when used as the primary, supplemental, or standby hydronic heating source. Standard Features VeSSeL ConStruCtion - Vertical ASME section IV, “H” stamped vessel, rated to 160 psi and 250º F. Registered with National Board. enCLoSure - NEMA 1, ventilated control panel with hinged door, key lock and vessel enclosure with removable panels mounted on steel channel base. Heat resistant silicon acrylic enamel protects all surfaces to 180º F. inSuLation - To minimize heat loss, vessel is insulated with four inches of one pound per cubic foot density fiberglass. Safety PreSSure reLief - ASME rated pressure relief valve. HigH Limit Cutout - Manual reset high temperature cutout provides protection in the event of an over temperature condition. Low water Cutoff - Manual reset, probe-type cutout de-energizes boiler on low water condition. External test and manual reset pushbuttons provided to meet CSD-1. ControLS - Fused control transformer with on/off switch and indicator lamp provides control power. Steps ranging from 1 to 8 depending on the size of the boiler. Drain VaLVe - Provided for right side connection as standard, easily accessible from boiler front. gauge - Combination temperature/pressure-indicating gauge is factory installed for front visibility. main SuPPLy terminaLS - Furnished on all boilers for copper conductors. eLement BunDLe - Element bundle utilizes single bend in- coloy elements widely spaced for maximum heat dissipation to reduce lime build-up between passes. Element terminals are double sealed with epoxy and silicone rubber to ensure long life. Elements are individually replaceable. Incoloy will with- stand scaling and temperatures to approximately 1700º F. uL LiSteD - Under file No. E30432. Due to space limitations, some built-in features may not be available in combination with others; consult factory representative.  MODEL KW RANGE GALLONS INLET OUTLET W X D W X D OVERALL H H OVERALL F R                                                                                  46”06/24/2019 Steps and circuits based on 480 3 PH Power Boilers over 4 steps include progressive sequencer Standard controls are DIGITAL PID CONTROLLER For additional capacity, see Lattner Cabinet Series Capacities & Amps CAPACITY KW 7.5 10 15 20 22.5 30 35 37.5 45 50 55 60 67.5 70 75 80 85 90 95 100 105 120 135 150 165 180 195 210 225 240 25.6 34.1 51.2 68.3 76.8 102.4 119.5 128.0 153.6 170.7 187.7 204.8 230.4 238.9 256.0 273.0 290.1 307.2 324.2 341.3 358.4 409.6 460.8 512.0 563.1 614.3 665.5 716.7 767.9 819.1 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 4 4 4 4 5 5 6 6 7 7 8 8 1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 4 4 4 4 5 5 6 6 7 7 8 8 9.0 NA 18.0 NA 27.1 36.1 NA 45.1 54.1 NA NA 72.2 81.2 NA 90.2 NA NA 108.3 NA NA 126.3 144.3 162.4 180.4 198.5 216.5 234.5 252.6 270.6 288.7 31.3 41.7 62.5 83.3 93.8 125.0 145.8 156.3 187.5 208.3 229.2 250.0 281.3 291.7 312.5 333.3 354.2 375.0 395.8 416.7 437.5 500.0 562.5 625.0 687.5 750.0 812.5 875.0 937.5 1000.0 36.1 48.1 72.1 96.2 108.2 144.2 168.3 180.3 216.3 240.4 264.4 288.5 324.5 336.5 360.6 384.6 408.7 432.7 456.7 480.8 504.8 576.9 649.0 721.2 793.3 865.4 937.5 1009.6 1081.7 1153.8 480 490 490 500 500 500 510 530 530 540 540 550 550 560 570 600 600 600 610 625 650 650 760 760 800 950 1000 1120 1200 1300 18.0 NA 36.1 NA 54.1 72.2 NA 90.2 108.3 NA NA 144.3 162.4 NA 180.4 NA NA 216.5 NA NA 252.6 288.7 324.8 360.8 396.9 433.0 469.1 505.2 541.3 577.4 20.8 NA 41.6 NA 62.5 83.3 NA 104.1 124.9 NA NA 166.5 187.4 NA 208.2 NA NA 249.8 NA NA 291.5 333.1 374.7 416.4 458.0 499.6 541.3 582.9 624.5 666.2 MBH NO.
