The 3-burner Genesis E-325, with extra-large sear zone, delivers legendary Weber quality, performance and durability in a grill you can rely on to make outdoor cooking for family and friends easy and enjoyable. The PureBlu burner system sets this grill apart from the pack – featuring unique, tapered burner tubes that generate consistent pressure and flames and deliver even heat across the grilling surface. Flames are directed above the raised gas ports, while debris falls below, minimizing clogging and ensuring the grill lights every time. Natural gas grill is factory built to operate using natural gas only. Natural gas is delivered by your local utility through an underground pipeline system. Confirm that the branch supply line from the house to the grill is properly installed before using the grill prior to purchase. Confirm you would like a natural gas grill and not a liquid propane grill.
