Mechanical air intake openings must be located a minimum of ____ feet away from any plumbing vents?

15
20
10
2x the height of the vent

The correct answer is: 10

The correct answer is a minimum of 10 feet. This requirement is fundamental in construction and HVAC systems to ensure that mechanical air intake openings do not pull in harmful gases or odors from plumbing vent systems. Plumbing vents are designed to allow gases from the plumbing system to escape outside, which is vital for proper drainage and preventing sewer gas from entering the building. Placing air intakes too close to plumbing vents can result in the intake of these gases, potentially compromising the air quality inside the building. A distance of 10 feet provides a sufficient buffer to minimize this risk, making it a standard practice in construction regulations. The other options suggest either greater distances or a variable measurement based on the height of the vent, which are not standard requirements for this type of installation according to Massachusetts regulations. The 10-foot standard strikes a balance between practical installation and safety, reflecting established best practices in the industry.
