Drainage, Waste & Vent第 11 / 120 题
A vent terminal must be located away from an openable window. Which arrangement satisfies the code?
a.4 ft horizontally from the window with the terminal level with the sill
b.6 ft horizontally from the window with the terminal 1 ft above the top
c.8 ft horizontally from the window with the terminal at the same height
d.11 ft horizontally from the window
解析
A vent terminal must be at least 10 ft horizontally from a door, openable window, or air intake, or else extend at least 3 ft above the top of that opening. At 11 ft the horizontal separation is satisfied outright. The other options fall short of 10 ft horizontally and none of them reaches 3 ft above the opening.
