Fire Table – Fire Pit Insert

Fire Table – Fire Pit Insert

No mistakes to report today! Today is a post about our fire pit insert and burner setup. When I first started tackling this project, I knew there was at least one part that I couldn’t manufacture myself (yet). That part is the fire pit insert and the burner. In addition, I knew I would need to figure out the proper gas lines and fittings to run the burner from a propane tank. I am going to give you a recap of what I did. While I hope this is informative, it is not advice on how to set up your own fire pit. Gas can be dangerous and you should be cautious when working with it.

There are a ton of options on the old internet for fire pit inserts. Amazon, in particular, has a crap ton of options in various sizes. However, I’m generally concerned with Amazon product quality. I’m also concerned with their poor treatment of workers, and Jeff Bezos being the epitome of a billionaire who shouldn’t be a billionaire. There’s a whole lot there I’ll save for another post. Anyways, in this case, I was able to find another supplier that is not Amazon and is American made. has a ton of options for building your own fire pit (not an affiliate). The easiest and most straightforward is to get one of their kits. These come with everything you need to connect from the propane tank to the burner. I ended up just going with a fire pit insert and a burner from them. The rest of the hoses and connections I was able to get elsewhere for cheaper than the overall kit.

Here’s the insert that we chose.

And here’s the burner.

Once we got the insert and burner, I picked up all of the remaining pieces. Every setup is different, so it is hard to say exactly what pieces someone will need for their gas line. My general setup consisted of an air mixer, a gas line to the shutoff valve, the shutoff valve, another hose to the propane tank which included a regulator. Couple those pieces with various copper gas fittings and you’ve got yourself a working fire pit.

I used the cracked version of our concrete insert to test the fire pit once I had all of my connections in place. If you do anything with gas, make sure to perform a “snoop test”. This consists of putting soapy water on all of the connections. If bubbles appear at those connections, you’ve got a gas leak. 

One final note on air mixers. These help propane burn more completely and eliminate soot. They work by pulling in air as the gas passes through, adding more oxygen to help the propane burn more efficiently.

However, if your air mixer is located in an area that doesn’t vent, it may not be the best idea to use one. Gas can leak out of the air holes in an air mixer, right after the fire is turned off. If that area doesn’t vent (ours does), it can cause a small gas build up that can catch fire if you’re not careful.
