Quick Answer
Common installation mistakes with buried propane tanks include improper depth and setback from flammable structures, inadequate drainage and ventilation, and failure to follow manufacturer specifications.
Inadequate Depth and Setback
When installing a buried propane tank, it’s essential to follow the manufacturer’s guidelines for depth and setback from flammable structures, such as buildings and vegetation. Typically, this requires a minimum of 10 feet of clearance from any structure, with the tank buried at least 12 inches below grade. Failure to adhere to these standards can lead to increased fire risks and other safety hazards.
Poor Drainage and Ventilation
Inadequate drainage and ventilation around the buried propane tank can also lead to issues. This includes failing to slope the soil properly to prevent water accumulation, and neglecting to ensure adequate air circulation to prevent the buildup of explosive gases. As a general rule, the soil surrounding the tank should slope away from the tank at a rate of at least 1 inch per foot to prevent water accumulation.
Failure to Follow Manufacturer Specifications
Ignoring or failing to follow the manufacturer’s specifications for buried propane tank installation can have severe consequences. This includes neglecting to account for the tank’s weight and size, failing to use the recommended anchoring system, and ignoring local building codes and regulations. In the United States, for example, the International Fuel Gas Code (IFGC) and the National Fuel Gas Code (NFPA 58) provide comprehensive guidelines for the installation of buried propane tanks. Failing to comply with these regulations can result in costly rework, fines, or even safety hazards.
