What is the required minimum clearance from a vent termination to a building structure?

The required minimum clearance from a vent termination to a building structure is 3 feet. This distance is established to ensure that vented gases can disperse safely and do not accumulate near the structure, which can pose risks such as fire hazards or health issues due to the inhalation of harmful gases.

Maintaining this distance also helps in preventing any potential damage to the building material or finishes from the vent's hot exhaust. Additionally, it minimizes the chances of impacting nearby windows or doors, which might otherwise lead to backdrafts or contamination of the indoor air quality. Adhering to this standard is crucial for both safety and compliance with building codes.
