Natural Gas Applications:

Propane Gas Applications:

  • Propane (LP) gas is a heavy gas.  Applying too much media over burner holes may create back pressure and gas leakage resulting in gas pooling in fire pit.  Do not block propane gas burner holes with fire glass media.
  • Refer to manufacturers instructions for approved use of fire glass
  • Service and Installation should be performed by qualified professionals
  • Filler glass is not recommended for propane applications due to the limited amount of glass applied
  • Propane can produce a black soot which discolors fire glass.  Consider using dark colored glass
