Unless you make special arrangements with the seller, these orifices come unbored. This is a kit for certain JennAir grilles (720-0337) with four main burners, a searing side 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. They can be drilled to size to convert to natural gas or propane. Many bar-b-ques use these types of orifices and they might retrofit a number of other brands.

This set includes 6 orifices for a grille with up to 4 main burners, and a searing side 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 main burner orifices come as blanks and so does the pointed rotisserie orifice. All these orifices come unbored, so all orifices must be bored to specifically 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. JennAir.
