When we custom design and build fire pits for customers we use a fire pit kit because we are in Florida where most of our clients use propane gas. The fire pit kits we have been using are limited to 65K BTU’s because that is the limit to how fast a 20lb 5 gallon liquid propane tank is capable of vaporizing the liquid to gas.
However, when we install the same fire pit for a customer with natural gas or with an in-line large LP cylinder they do not love the flame patterns so we have started using a different fire pit kit.
The new features that I love about this new fire pit kit is that the burner is very heavy American made 304 stainless. Although we have always used 304 stainless materials the gauge of these materials are heavier.
The control valve is in a sealed box whereas the old kit we used was open in the back. The front was sealed so it looked “finished” when we built the control panlel into a fire pit or a column but inside the structure it was open to the elements and the critters we try not to think about who live in these sealed damp, dank areas… who will sometimes chew through wires.
Also the burner sits low so we are able to pour lava rock and fire glass on top of the burner. On this new kit the pilot assembly sits higher so we can pour more media on the burner. As gas leaves the burner we want it to have to push its way through the media so there is a better flame pattern and an accumulation of gas before ignition so there are not only better flame patterns but better flames. Also the pilot is mounted easily to allow us to raise it higher if necessary.
Finally the orifice in the safety valve is set for 90K BTU’s and the module is a 9v battery module. The sealed box protects these controls but the controls themselves are a lot stronger with higher settings so pragmatic day-t0-day use of the custom firepit is more enjoyable with less opportunity for failure.
