Hi all - had a few questions retro-fitting my old Viking gas grill (model # VGBQ5304RE2LSS) to add ceramic briquettes like the new models have. The current grill has heat shields but I have had issues with flare ups in the past and have read that the ceramic briquette solution might be superior to that of the heat shields. After talking with the parts department at Viking their view was that this old model cannot be "upgraded" to the ceramic briquette parts but I find it hard to believe there are not 3rd party OEM solutions I could explore. Has anyone had experience in this area and, if so, could you suggest any briquette trays that could potentially work on our grill? Appreciate the help and let me know if you need any further info!
