NOTES REGARDING PERFORMANCE DATA:
1. Sensible cooling data is based on a six (6) foot long uncapped beam with a 12" stack height (H), a ceiling free area of 50%
and an air passage width (W) twice the beam width (B) per figure 17. 13.
2. For other beam lengths, ceiling free areas and/or air passage widths see table 3 for correction factors.
