Quick Answer
HEIGHT_LIMITATIONS: Propane tank vent height requirements vary by jurisdiction but typically range between 6 inches to 3 feet above ground level to prevent snow from accumulating and to ensure proper ventilation.
Venting Requirements
The National Fire Protection Association (NFPA) 58 standard, which governs propane tank installations in the US, requires that vent pipes be at least 6 inches above grade to prevent snow accumulation and ensure adequate ventilation. This height requirement also helps to prevent ice from forming around the vent, which can block airflow and cause tank pressure to build up.
Tank Depth and Venting
When installing an underground propane tank, it’s essential to consider the depth of the tank in relation to the required vent height. A general rule of thumb is to install the tank at a depth that allows the vent to be at least 6 inches above grade. For example, if the vent is 18 inches above the tank, the tank should be installed at a depth of 12 inches or more to ensure the vent is above ground level.
Common Vent Pipe Heights
Typical vent pipe heights for underground propane tanks range from 6 to 36 inches above grade, but the exact height will depend on local regulations and climate conditions. In areas with heavy snowfall, it’s not uncommon to install vents as high as 3 feet above grade to prevent snow accumulation and ensure proper ventilation.
