Vento Heater.—^The Vento cast-iron heater, made by theAmerican Radiator Company, is shown in Fig. 153. This isconstructed especially for hot-blast work and is made up of sec-tions with projecting hollow pins for increasing the radiatingsurface and for breaking up the air currents as they pass betweenthe sections. Heaters of this type are made in three sizes, asfollows: the 40-inch section, containing lll^ square feet of sur-face; the 50-inch section, containing 14 square feet; and the 60-inch section, containing 17 square feet. FORCED BLAST HEATING AND VENTILATION 221 Table LIV, gives working data relating to this type of heater. Efficiency of Pipe Heaters.—The efficiency of the heaters usedin connection with f
