I need a conversion kit # to change from natural gas to propane for a magic chef mdl31213wav

SOURCE: LP Conversion Kit?

I'm looking for the same thing! My kitchen is covered in black soot and the inside of my new oven is BLACK!!!

SOURCE: Natural Gas to Propane for Ge xl44 Gas range

The kit is located at the rear of the range right near the gas valve, there are probably 5 spuds and an extender for the large burner, directions are with the range. For the bake and broil you will need to tighten the brass orifice nuts down as tight as possible, also the brass nut on the gas valve needs to be reversed
your local LP dealer should be able to do this for you if you are uncomfortable doing it yourself.

It is inconceivable to me that large manufacturers like Jenn-Air and Nexgrill can jointly make and sell an expensive grill and then completely abandon the consumer. I purchased an Jenn-Air 740-0142 LPG and like so many wanted to convert to nautural gas which requires a larger gas orifice. I spent a month on the internet and phone calling Jenn-Air and finally Nexgrill who actually manufactured the unit in China. The Jenn-Air and Nexgrill serial numbers are the same. the 740 prefix is LPG and the 750 prefix is natural gas. After three calls to Nexgrill I found a manager who actually acknowledged making Jenn-Air but declined selling me parts for it as I believe they have product liability concerns. I call back as a Nexgrill owner and finally ordered natural gas orifices at $10.00 each. The shipment never showed up. Calling back again I was told that they really didnt really have any orifices in stock but could sell me the entire replacement gas valve for $28.00 which I purchased. The valves actually arrived on the shipping receipt was from The Grill Services in City of Industry 909-718-6128 www.grillservices.com . Part number 750-0141/142/593/594.

Forget about pirates in Somalia... we have them right here. Shame on you Jenn-Air and Nextgrill.

Apparently, Weber does not make a conversion kit to convert the grill from propane or from natural gas to propane. According to the Owners Manual - "Liquid propane gas is not natural gas. The conversion or attempted use of natural gas in a liquid propane unit or liquid propane
gas in a natural gas unit is dangerous and will void your warranty." (From Page # 3 of the Owners Manual)
