6. Louvers and Grilles of Ventilation Ducts
a. All outside openings should be screened and
louvered. Screens used should not be smaller
than 1/4 inch mesh. Louvers will prevent the
entrance of rain and snow.
b. Free area requirements need to consider the
blocking effect of louvers, grilles, or screens
protecting the openings. If the free area of the
louver or grille is not known, assume wood louvers
have 20-25 percent free area and metal louvers
and grilles have 60-75 percent free area.
c. Louvers and grilles must be fixed in the open
position, or interlocked with the equipment to
open automatically during equipment operation.
