This video will show you how to replace a burner orifice.

Sorry, I haven't ever had to replace the oven stuff. Did the kit just consist of a bunch of orifices like the one I show in the video linked above? Or are there also replacement gas valves?

aabny, if you do not mind, I would appreciate it if you would post a note in this thread when you do the swap. What I would like to know is what number is stamped on the replacement orifices that go on the 22k RNB, the 15K NB, and the 8K simmer burner. I know what size the natural gas ones should be, but I would like to know what sizes the LP version uses for each burner. The drill size or "gauge" of each orifice is stamped in the brass. It should be easy to spot. Thanks!
