Note: The “spread” is the diameter of the comfort zone at fl oor level. The above table represents the spread for standard units without a louver
cone diffuser and mounted at its maximum height at 2 PSI (13.8 kPa) steam pressure and 60°F (16*C) entering air. (See Table 16 for maximum
mounting heights.)
