What is the minimum distance a vent termination point should be from an interior corner formed by two walls?

The minimum distance a vent termination point should be from an interior corner formed by two walls is 3 feet. This requirement is established to ensure adequate dispersion of exhaust gases and to minimize the risk of those gases being drawn back into the building. By having this distance, the design reduces the chances of creating a pocket where exhaust could accumulate, thereby enhancing ventilation and air quality within the space.

When vents are improperly positioned too close to walls or corners, there is a greater risk of the discharge interfering with fresh air intakes or stagnating near those structural features, which could lead to potential safety hazards. The 3-foot minimum is a code requirement that helps ensure safety and effectiveness in the home's mechanical ventilation system.
