How to Build a Propane Fire Pit
A propane fire pit is an ideal place for your family and friends to enjoy outdoor activities while preparing a barbecue. You can use one of these pits safely, without the cost and effort of hauling in wood for a wood fire pit. What's more, you don't have to be concerned about starting and dousing your fire. Turn on the gas to begin your barbecue, and when finished, turn it off. Here's how you can build your propane fire pit.
Step 1 - Preparing your Pit Area
Use a long measuring tape and a can of white spray paint to designate the part of your backyard where you'll want your fire pit. If your hole is in your backyard lawn, you'll need to decide what you'll do with the soil and sod you remove to make room. Also, you'll need to check with local utility companies to locate utility pipes or lines that may be buried.
Step 2 - Digging Your Pit
Decide whether you will dig the pit yourself or whether you will hire someone with a backhoe. If you choose the backhoe route, you'll need an entrance for the backhoe to get into your backyard. Once you have removed the sod and soil, smooth out the surface of your pit with a garden rake and shovel. Be sure the surface is smooth and level. Remove any large rocks, tree roots, or other debris you dig up.
Step 3 - Building Your Frame
Cut 5-foot pieces of 2X4s and fasten them into a square frame to be used for your concrete slab. Use a carpenter's level to be sure the frame is level. If necessary, remove or add soil. Lay rebar on the ground within the frame.
Step 4 - Pour Your Concrete
Pour your concrete into the frame you've made. Use a shovel or hoe to spread and even the concrete until it fills all the space in the form. Use a tamper to remove any air pockets in the concrete. When the concrete is filled level with the top of the form, use a screed to smooth the concrete surface.
As the concrete sets, use a trowel to finish the surface, then allow the concrete to set up. Install a propane regulator and run a copper tube to it from your propane tank, then connect the tube to your regulator.
Step 5 - Install Concrete Blocks
On top of your concrete, lay a bottom course of concrete blocks, then lay your cap blocks in place on top, using mortar and trowel.
Step 6 - Install A Stone Wall
Using mortal to bind your wall stones together, build up a stone wall against the exterior side of your concrete block course with manufactured stone. Lay a stone cap on top of the concrete and stone walls, using mortar to seal it.
Step 7 - Connect Your Propane Tank and Regulator
To the copper tubing you installed, connect your propane tank. Fill the pit with stones or lava rock, then add artificial embers or logs.
