Heater Throw
Figure 1 shows throw patterns for fan model units. Table 3 lists throw distances for standard, adjustable horizontal
louvers on heaters suspended at varying mounting heights. The louver angles listed are relative to the top of the
heater. The throw pattern changes with the addition of optional vertical louvers and/or downturn nozzles.
Z = Distance at which air velocity drops below 50 feet (15.2 meters) per minute
