I just bought Mom a brand new GE gas range. I converted it to LPG myself. There lies the problem? Not this time. All the top burners worked correctly as did the "Bake" burner in the bottom of the oven. Unfortunately the "Broiler" burner had very large flames that were two-thirds yellow. I followed all instructions to the tee.
Since it's brand new I scheduled a service call for the following Monday. I got home just as he found the problem. According to the service guy, the folks in Mexico that build the range often put too much "thread lok" on the threads for the adjustable orifice. This makes is very difficult or impossible to adjust in all the way down. The instructions warn more than once about not tightening this adjustment too much. So, I didn't give it everything I had but I did give it a good pull so to speak.
Anyhow, this guy cleaned some of the "thread lok" off the threads and reinstalled the adjustable orifice. He said it required only one-quarter more turn than I had given it. So here you can follow all the instruction perfectly but still be out of luck because of poor workmanship at the factory.
The good news is that if you back the nut off a bit and retighten it a few times you will eventually be able to close it down enough to actually get the adjustment correct.
The ranges come with the adjustable orifice opened up two and half turns to work on natural gas which is from what I understand the way all ranges for the most part come from the factory. Just get that adjustment tightened down FAR ENOUGH and you'll be O.K.
Very important though. Use finesse to get the adjustment turned down enough. In other words you may have to do a bit of burner disassembly in order to clean of some "thread lok". I believe if you open and close the adjustment a few times while keeping track of just how far down you can tighten the damned thing you will be O.K. You should be able to get the feel if you're starting to round off the brass nut or bend anything.
Just remember what you're fighting. Too much "thread lok". With that in mind you can get it adjusted properly.
I hope this helps.
