I have an old Natural Gas ventless fireplace that I never used. I now want to build a fire pit and am wondering if I could take the working parts out of the fireplace unit and use those for fire pit. I have already disassembled the fireplace and have included a photo of the parts. I plan on covering the fittings with fire glass.

I have attached a couple of images, but, have more detailed ones too of the individual parts, if needed.

Any suggestions or comments would be greatly appreciated. Thanks! enter image description here enter image description here

  • Natural gas and LP gas often need different orifices for proper air-fuel mixtures. Commented Jan 14, 2016 at 1:52

You will need to change the gas orifice to a smaller size on the output of the control valve to the burner. You will also need to make sure the regulator from the tank to the control valve is 1/2 psi, other than that should work great.

  • Wonderful! I have seen the conversion kits at Lowes. I will take a look at those and make sure I change both the output and the control valve regulator, if needed. Thanks!
