Step 1: Prepare the Area

First measure and mark off the area where the fire pit will be located using a measuring tape and spray paint (Image 1). Use a backhoe to dig out the area for the fire pit (Image 2). Use a rake to make the area level.

Step 2: Build the Frame

Cut a 5'x5' frame out of lumber. Nail the pieces together and secure them into the ground at the corners using wooden posts and a mallet. The frame will act as a template for the concrete pad that will be the base of the fire pit. Make sure the frame is level and then add more support using rebar.

Step 3: Add the Concrete

Pour quick setting concrete into the frame to create a solid foundation. Screen until it's smooth and level. Be sure to give the concrete plenty of time to set up and dry. Install a propane regulator by hooking it up to the copper tubing ran from the propane tank. Professional assistance is recommended for this procedure. Once the concrete is dry, remove the temporary wood frame.

Step 4: Begin Adding Cinderblocks

Mortar a single course of cinderblocks into place on the cement base. This creates the frame that stone will eventually adhere to (Image 1). Use a trowel and mortar to attach cap blocks to the top of the cinderblocks. Use the trowel to tap the caps into place and remove any excess mortar, making sure each piece is level. The pieces lining the interior may need to be measured and cut down to the correct size. This creates the base for the field stones. Allow these to set up and dry (Image 2).

Step 5: Add the Stones

Add dirt to fill in the area around the fire pit to level the ground (Image 1). Using mortar and a trowel, attach manufactured stone to the exterior sides of the fire pit. Cover the top of the fire pit with field stone, once again using mortar and a trowel (Images 2 and 3). Measure and cut the stone accordingly and secure in place using the mortar.

Step 6: Connect the Gas Line

Connect the gas line to the regulator using Teflon tape. Professional assistance is recommended for this procedure. Top off the fireplace with gas logs and embers. For our fire pit, we opted for lava rock.
