Underground Propane Tank Installation Guide — What Buyers Need to Know

Long Beach Steel Corp distributes these tanks to homeowners, licensed LP-gas contractors, and commercial project managers. While we do not perform installations directly, our team provides full technical pre-sales support to help you and your installation contractor plan a compliant, efficient project. Below is a practical underground propane tank installation guide covering the key requirements your licensed LP-gas contractor will follow.

Site Planning & Setback Requirements (NFPA 58)

Per NFPA 58 Table 6.4.1.2, a 1,000-gallon underground LP-gas container must maintain the following minimum distances:

Note: Local AHJ (Authority Having Jurisdiction) requirements may exceed NFPA 58 minimums. Always verify with your local fire marshal or building department before finalizing tank placement.

Excavation & Bedding

• Excavate to a depth providing a minimum 18 inches of soil cover over the top of the tank; 24 inches minimum in areas subject to vehicle traffic
• Trench dimensions: allow at least 12 inches clearance on all sides of the tank for bedding material
• Bedding material: Clean washed sand or pea gravel (3/8″ minus) — minimum 6-inch layer under the tank bottom to protect the FBE coating from rock point loading
• Remove all large rocks, construction debris, and sharp objects from the trench before lowering the tank

Tank Lowering & Anchorage

• Use a certified crane or excavator with approved lifting straps rated for the tank’s weight (~1,150 lbs empty)
• Never use chains or wire rope directly on the tank shell — use wide nylon straps to protect the FBE coating
• In areas with a high water table (within 5 feet of the surface), install concrete deadman anchor slabs or approved anchor strap assemblies to counteract buoyancy forces — an empty 1,00
  • 0-gallon tank has significant flotation potential
  • Confirm tank is level (±1/4″ over length) before backfilling

  Cathodic Protection & Backfill

  • Connect the pre-installed magnesium anode lead wire to the tank fitting per the manufacturer’s anode guide
  • Install an above-grade test station to allow periodic corrosion potential measurement per NACE SP0169
  • Backfill with clean native soil or imported sand in 12-inch lifts, compacting lightly around the tank; avoid heavy mechanical compaction directly over the tank dome
  • Anode test potential: Initial reading should be −0.85V (CSE) or more negative; document and retain for inspection records

  Above-Grade Connections

  • First-stage regulator mounted at the service valve inside the dome or immediately above grade
  • All underground supply piping must be approved LP-gas grade — CSST (corrugated stainless steel tubing) or Schedule 40 black iron with approved LP-rated coating, or pre-approved polyethylene (PE) LP-gas pipe
  • Pressure test all piping per NFPA 58 before commissioning
