Why You Need a Conversion Kit

Why do you need a propane conversion kit? Propane by nature burns very differently than natural gas. Where natural gas burns a lot cleaner with very little black smoke or soot, propane does not. Our propane conversion kits allow more oxygen to mix with the gas, allowing it to burn clean without creating smoke.

½" Propane Conversion Kit

If you’re using propane gas for your fire display, then you need a propane conversion kit. Our standard ½" kit comes with a brass air mixer and a stainless steel coupler. Our propane conversion kits are available in various BTU ratings.

¾" Propane Conversion Kit—High Capacity

If you’re using a larger system, then our ¾" High Capacity Propane Conversion Kit is the best option to optimize the use and quality of your fireplace or fire pit. This propane conversion kit comes with a brass air mixer, brass adjustment nut, and a stainless steel coupler.

This feature has a maximum BTU of 300,000.

Propane Air Mixer

If you’re not looking for the entire kit, Starfire Direct also offers individual air mixers.

Why do you need an air mixer? Well, for one cubic foot of natural gas, you only need 10 cubic feet of oxygen for combustion. However, for every one cubic foot of propane gas, you need 24 cubic feet of oxygen for combustion. 

Because propane requires more oxygen than natural gas, air mixers are essential to achieve proper propane combustion. Moreover, propane air mixers reduce the amount of soot caused by pure propane and allow for better flame quality.

Always remember to test your burner before you put away your tools!
