There might be a better section to post this.

I have a propane grill, about 15 years old - was a quality grill at the time I bought it. There are two burners - the left side was shooting yellow flames - I inspected the burner, and it was rusted out. I've replaced the burner, but the left side still produces more yellow flame than the right (the 2 burners are in a single piece - a figure 8). When the left side is on high, it makes a significantly louder hiss than the right side.

I disconnected the burner (and I'll probably make the pros shutter at my methodology) I held a match in front of the jets that normally fit into the venturi tubs. Both appear to shoot out equal length flames.

Since it's a new burner, and I've inpected it and there are no spider webs inside, can anybody give me any answers?

Are the orifices the proper ones? They come for propane and natural gas and they are two different items.

How about the dampers? Are they adjusted properly.

About doing what you did with the match...ARE YOU CRAZY?:laughing:

I remember when I first purchased the grill, I had huge flames shooting out of the burners - when I called the retailer, they were chagrinned and came out and swapped out some fittings. They said it had been set up for natural gas.

I assume by orifice, you're referring to the "jets" that fits into the venturi tubes. They each have a pinhole that the gas comes out of. They look the same.

And by dampers, I assume you mean adjustable venturi closings. Neither the new or old venturi tubes have adjustable dampers, though I have attempted to cover parts of those holes and it does seem to make a little difference.

As to the crazy part - that's why women live longer than men.:whistling2:

Yes the "pinhole" things.

I'm only guessing as I have been down this path a time or two but don't pretend to understand any of it. I do know the orifice variables are just barely detectable to my eye, there isn't much difference in appearance that I could ever see between the propane and the natural gas. I have never seen a gas burner anything (of the outdoor grill type) that didn't have air adjustment dampers.

Thanks - I'll look into the pinhole issue again (perhaps using a more scientific method). The two sides aren't wildly different, so I can live with it.

Thanks for your iput.

Someone will be along shortly with some real knowledge of these things I'm sure. Then we can both learn.

I finally went back to charcoal anyway.
