The minimum airflow for Type I hoods used for high-temperature appliances such as deep-fat fryers shall be determined as follows:
Number of exposed sides | Formula | |
For SI: | ||
4 (island or central hood) | Q = 150A | Q = 0.76A |
3 or less | Q = 100A | Q = 0.51A |
Alternate formula | Q = 100PD | Q = 0.51PD |
