Determine the location of the fire pit. This site should be in the yard or patio, not far from a gas connection. The site also should not be close to the house where combustible materials may catch fire from sparks.
Remove the decking, pavers or other floor material from the area chosen for the fire pit.
Dig a pit to a depth at least 4 inches below the surface of the surrounding materials, but not deeper than 8 inches.
Lay down a solid base for the burning unit with a non-combustible material such as metal, concrete or tamped-down soil.
Line the sides of the pit with stones, leaving a small opening for the entry of the gas pipe. Turn off the gas valve to the house.
Pipe in the gas line from the house to the gas burner. Use a pipe wrench to connect the pipe extension to the fire pit, and use yellow gas connection tape to secure the threads, wrapping them from the end inward.
Install a shut-off valve within 3 feet of the fire pit, according to the Fireplace Distributor website. Connect the valve to the gas pipe with a pipe wrench, first sealing the threads with yellow gas tape to prevent leaks.
Connect the gas line to the burner and secure it with gas tape.
Turn on the gas to the unit and test for proper connection with a solution of soap and water to detect leaks.
