Product review (3 stars): More closely resembled a GRLP4 kit instead of GRLP3.
The GRLP3 LP conversion kit did not meet my expectations.  Although the outside plastic packaging indicated the kit was a GRLP3, the material inside the kit, including the instructions, were labeled GRLP4.  There were twelve orifices in the kit which match pictures of the GRLP4 kit instead of twenty-one orifices as shown for the GRLP3.
All the information I could find for my stove stated the GRLP3 was the proper kit to use and not to use the GRLP4.  However, the orifices in the kit I received were numbered in accordance with what I needed to convert my stove to LP so I used them and they work.
My biggest complaint is the confusion that resulted from the labeled contents of the package, i.e. the instructions and labels that should be affixed to the stove after conversion which had GRLP4 on them instead of GRLP3 and the number of orifices in the package.
