Core Cooking System Components

The heart of the Weber GS4 lies within its cooking chamber, where every element is calibrated for excellence. Maintaining these parts is the key to ensuring your food cooks evenly and efficiently, without any flare-ups or cold spots.

Cast Iron Grates and Flavorizer Bars

At the top of the GS4, you will find porcelain-enameled cast iron grates, renowned for their ability to retain heat and create superior sear marks. These grates sit atop the Flavorizer Bars, which are the unsung heroes responsible for vaporizing drippings and producing that signature smoky flavor while protecting the burners from direct grease exposure.

Burner and Grease Management

Propane gas is delivered to the system via stainless steel burners, which are positioned directly above the evenly distributed grease catcher bowls. This layout ensures that heat output is consistent across the cooking surface, while the bowls safely collect and contain drippings, preventing them from interfering with the ignition system or creating unwanted smoke.
