Heater Throw
Figure 1 shows throw patterns for fan model units. Table 2 and Table 3 list throw distances for standard, adjustable
horizontal louvers at the angles listed. 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
