I found the manual and it said that you can adjust how low the flame gets by pulling off the knob and turning the screw inside the stem. adjusting each burner individually.
after getting a flashlight and squinting just right i was able to see the screw. Now i need to find a screw driver that will get in there. i need something as small as a jewelers screw driver but i dont think they will be long enough. hmmm. i think this calls for a trip to the hardware store.
Jeff the model number is VER2503357. and it was converted just not adjusted.
