Shelly and I have had this Weber propane grill for probably 15 years or more. Today, I finally decided to convert it to natural gas. It took a little research and a $99 conversion kit for a different brand of grill (Weber doesn’t do conversions)
When the gas was installed at the house, I asked for an extra outlet on the patio so I could connect a gas grill. I thought it would be convenient to run it off the same gas as the house.
I also assumed it would be easy to switch fuel, but that wasn’t exactly correct. Weber doesn’t make a conversion kit and so I had to do a little math to figure out whether or not I was going to be able to use the old grill for this. I really don’t want to buy a new one just now.
Apart from the plumbing, the natural gas system needs a larger hole for gas to flow into the grill. Propane burns hotter, and is under higher pressure. I had to drill these holes in the brass fittings that allow the gass into the manifold.
This operation requires small bits. Ultimately, with some trial and error, I settled on the 1/16th bit. It is in the ballpark, but I may actually need to increase the hole size just a little more, so I ordered a new set of wire gage bits that have much finer increments than these fractional sizes.
We actually made nachos on the grill today. It still needs some new parts, but I think today’s conversion may have given it a new lease on life.
