What is the minimum distance between a direct vent and the ground?

The minimum distance between a direct vent and the ground is 12 inches. This requirement is in place to ensure that the venting system operates safely and effectively. The distance helps to prevent potential blockages from snow, debris, or moisture that could cause backdrafting or other issues impacting efficiency and safety.

Direct vents are installed to allow combustion gases to be safely expelled outside, while also drawing in fresh air for combustion. By maintaining a height of at least 12 inches above ground level, the risk of these vents becoming obstructed is reduced, ensuring proper airflow and preventing hazardous conditions such as carbon monoxide buildup inside a structure. This regulation is generally outlined in the building codes and installation guidelines, which emphasize the importance of safety in HVAC installations.
