What would be the parts (or kit) needed to convert this stove to LP gas?
Answer Bob, to convert the unit to LP you'll need conversion kit part number WB16K5042. Unfortunately, this item has been discontinued with no further replacements or cross references available and our company is unaware of any other available sources. Sorry about that!
What are the part numbers for top burner orifices to convert to natural gas?
Answer Nancy, you will need the left front orifice holder WB28K10190, right front orifice holder WB28K10239, the right rear orifice holder WB28K10188, and left rear orifice holder WB28K10187. You will need to flip the nut on the regulator back to NG. Thanks!
