*Required for electric steam control and electric low water cut-off safety circuit Through November 1982, these components were used
in lieu of the #22151 steam control valve as standard equipment on all 24" and 60" wide cabinets and all California units, but optional on
36" and 42" wide cabinets. After November 1982, the #22151 was not used and the electric controls became standard equipment on all
steam coil generators.
**Required for electric (solenoid valve) water fill, used in lieu of the #43720 water regulator valve, beginning April 1984.
***Optional, if steam supply is wet.
