Old Roper 20072 LP conversion

I have done this several times. There is an orfice (jet) which needs to be replaced for EACH burner. If you remove a burner, this orfice is immediately at the point the burner attaches at the gas supply end. It has a very small hole in it, and it's brass. It unscrews like a pipe. They are easy to change, *IF* you can get the LP gas orfices. (Good luck findng them).

Some of the older stoves had an adjustible orfice, so the same orfice could be used for either gas. (Try to find a manual for the stove online).

The pilot also needs to be modified. That is easy. Where the small gas line which goes to the pilot, attaches to the main gas pipe at front of stove, there should be a small screw slotted (for regular flat blade screwdriver). Turning it left should reduce the gas slow, and a right turn increases the flow. For LP you want to reduce the flow (LEFT). You normally want about 3/8" or 1/2" flame. (These lefts and rights could be reversed on some stoves, I am guessing).

LPG is supplied at a higher pressure and has a higher BTU rating per unit . All the jets needs to be replaced with CORRECT smaller jets . Newer ranges also have a pressure regulator on the stove that needs to be reset . I just converted a new range ... it came with all the needed parts .
