Question about Jenn-Air JGR8750 Gas Kitchen Range
We got a used range (Jenn-Air JGR8750, unknown age) that was used on LP gas. We need to turn it to natural. There were no extra orifices hidden anywhere on the unit. One place I called said the parts were $70; another said that since the orifice assemblies were not listed as LP vs. natural that they must be adjustable.
Does anyone know the truth of the matter? Thanks! (yes, my husband is going to do this himself no matter what)
gas is not in a diy domain and it is more dangerous to work on gas than electricity
next the change over from to natural gas is a matter of the correct size gas jets for natural gas and adjustment of the air shrouds to get the correct air /gas ratio
get in a gas fitter to do the job and be safe

Where do all orifices go on anything gas? Right there where the burner meets gas valve. The air shutter sits right in front of the orifice for proper air to gas ratio right.Go out and look at yer gas grill. Where the burners meet the gas valve ye shall find the orifice.

SOURCE: I converted my 40
I am having almost the same problem. Frigidaire told me to replace all 5 mixing tubes, ~$385, yeah right. They don't have the orifices itemized as an individual part, so no-one carries them, just the LP conversion kit. Another repair/parts guy advised me to drill out the orifices. Some other threads/blogs give the diameter to drill. Basically, since natural gas is 0.5 psi, you need a larger hole than your current propane orifices provide. Please speak up if you find out anything, I will try to do the same. Good luck.
