This is a kit for certain JennAir grilles (720-0099) with three burners, a side (stove style) burner and an infrared (rotisserie) burner (at the back of the unit).

These brass orifices are a replacement for grilles that use male threaded orifices. Some of these units have larger single piece main burner orifices (which I have under a different listing ID) so make sure these are the correct ones for your model. They can be drilled to size to convert to natural gas or propane. Make sure to measure your orifices carefully before ordering. Many bar-b-ques use these types of orifices and they might retrofit a number of other brands.

This set includes 5 orifices for a grille with up to 3 main burners, and a stove style burner on the side deck, a smoker burner and an infrared (rotisserie) burner at the back of the unit. It is usually necessary to swap the regulator as part of the conversion. Other manual adjustments might be necessary, so check your factory instruction manual details.

The larger orifices come with a #72 pilot holes while the smaller orifices come with #64 pilot holes, so they must be bored to suit your application. Seller will bore them to your specification for an additional fee, but you must contact seller prior to ordering, otherwise you will need to bore these yourself before your can use them. International buyers, please inquire about international shipping rates before ordering. FOB origin.
