A vent is proposed to terminate through a sidewall at a point 4 feet below an openable bedroom window and 5 feet to the side of it. Take as given the code rule that a vent terminal must be at least 3 feet above any opening within 10 feet of it. Does the proposed location comply?
- AYes, because the terminal is more than 3 feet away from the window measured in a straight line
- BYes, because the rule applies only to terminals located above an opening, not below one
- No, because the terminal is within 10 feet of the opening and is below it rather than 3 feet above it
- DNo, because a sidewall terminal may never be located on the same wall as an openable window
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why C is correct
Apply the rule supplied in the question. The terminal is only 5 feet horizontally from the window and is 4 feet below it, so it fails the requirement to be at least 3 feet above an opening within 10 feet. A straight-line distance greater than 3 feet does not satisfy an above-the-opening requirement. The stated rule does not ban all terminals on walls with windows. Other sidewall-terminal and local-code requirements must be checked separately.
