Where should gas pressure regulator vents terminate in relation to doors and windows?

The correct answer indicates that gas pressure regulator vents should terminate at least 3 feet away from doors and windows. This requirement is based on the need to ensure safety and prevent the potential for gas to enter buildings. When gas escapes from a regulator vent, it can create a hazard if it accumulates near building openings where people may enter or exit, increasing the risk of ignition or exposure.

The positioning of the vent helps to maintain a safer environment by reducing the likelihood of gas entering through doors and windows, which could occur especially when windows are open or doors are regularly used. This distance also considers various environmental factors, such as wind direction, which could carry gas toward entry points.

Properly locating gas regulator vents is crucial not only for compliance with safety regulations but also for maintaining indoor air quality and ensuring the safety of occupants.
