  • Consider using crushed lava rock as a filler material with fire pit logs or larger lava rock
  • For propane applications do not cover burner holes with crushed lava rock

Important! Wet Lava Rock

  • Lava rock which is wet or has moisture inside can pop or burst causing pieces of hot rock to fly out of the fire pit.
  • Allow fire pit to burn at least 30 minutes prior to coming within 15 feet of the fire pit if this condition exists
  • Consider covering fire pit when not in use to prevent lava rock from getting wet
