OK. Now back to your question. In order to convert to lpg operation, you need to replace the burner orifices with ones sized for lpg operation. Roughly speaking, you need orifices with half the drill size as you now have for natural gas. To determine the proper drill size, go to 'www.andersonforrester.com/orifice_camacities/default.html'. You can download a very useful conversion chart at the website.
If you need further assistance, please post back to me.
Hi Jon - This stove is as old as you are probably - so maybe 20 years experiece may not cut it - on the tag it says that this range can be used for propane or natural gas - it seems to say that for propane use the orifice hoods must be screwed down tight - we did that and get a nice flame - so according to the instructions this range has adjustable orifices. The BTU rating for the oven - natural gas = 24000 - propane = 21000 - we were more concerned about the safety aspect - and hoping to bypass the electrical sensor for the oven as there is no electricity there - or do we need some sort of sensor that is not governed electrically - or can the oven temperature control switch be used as is? thanks Joe
