BBQ Depot and Broilmaster worked with me to identify the correct venturi for my 2009 grill. It was not easy as the model# was no where to be found.. P3 or P3X ?
I finally measured all my old parts and searched online for parts with those dimensions. Voila, the Broilmaster P3X, P4X Bowtie Stainless Burner Kit (2011 and newer) - DPP111
had the correct dimensions for my pre 2011 grill. Parts came and installed easily. All works! All good :-)
