The Weber Genesis II LX S-440 Stainless Steel Natural Gas Grill is designed for homeowners who already have—or are willing to install—a natural gas hookup in their backyard or outdoor cooking area. While adding a gas line may require some upfront plumbing expense, the convenience can be well worth it. With a direct connection to natural gas, you never have to worry about running out of fuel in the middle of cooking or dealing with the hassle of refilling propane tanks.
What makes this model especially appealing is that it offers far more than standard grilling capability. The Genesis II LX S-440 is not simply a grill—it functions as a versatile outdoor cooking system that can take the place of several kitchen appliances. Depending on the accessories you choose, it can handle tasks normally reserved for a griddle, oven, frying pan, or stovetop burner, allowing you to cook everything from breakfast foods and seared meats to steamed vegetables and boiling water. Because of its versatility, many owners find themselves using it as a true extension of the kitchen, especially during warmer months when cooking outdoors keeps the house cooler and more comfortable.
For some users, this grill becomes the center of summer cooking, making indoor meal preparation almost unnecessary. Instead of heating up the kitchen, you can prepare full meals outside with ease and enjoy the outdoor setting at the same time. Its performance is so capable, in fact, that you may even find yourself choosing the Genesis over your indoor oven for larger meals such as a holiday turkey or ham, even during the colder months. This grill is built not just for casual weekend barbecues, but for those who want a premium, all-purpose outdoor cooking experience year-round.
If you are in the market for a higher end Weber NG Grill, may we suggest the Weber Summit S-470 Natural Gas Grill? This 48,800 BTU Natural Gas Grill has a Tuck-away rotisserie is designed for a natural or city gas line plumbed in and even comes with a 10-foot flexible hose for convenience.
Cooking Grates & Tuck-Away Warming Rack
The stainless-steel cooking grates on the Weber Genesis II LX S-440 are designed to provide consistent heat distribution across the entire cooking surface. The thick stainless-steel rods retain heat extremely well, helping create those classic restaurant-style sear marks on steaks, burgers, and other meats while maintaining even cooking temperatures.
Unlike cast-iron grates, which often require frequent seasoning and careful maintenance, or chrome-plated grates that can eventually rust or wear down, these stainless-steel grates are built for long-term durability and easier upkeep. Stainless steel naturally resists corrosion and holds up well to years of regular grilling.
Another thoughtful feature is the Tuck-Away warming rack, which adds extra flexibility while cooking. This rack allows you to keep finished foods warm while the rest of the meal is still grilling. It’s also perfect for lightly toasting burger buns or hot dog rolls without taking up valuable space on the main cooking surface.
When you don’t need the extra level of warming space, the rack can be folded down and tucked away, giving you more room for larger cuts of meat such as turkeys, briskets, racks of ribs, or a full Boston butt. This simple but practical design helps maximize your usable cooking area whenever you need it.
Side Tables with Tool Hooks
The Genesis II LX S-440 also includes sturdy side tables that provide valuable workspace while you cook. These surfaces make it easy to prepare ingredients, season meats, and hold serving platters, keeping everything within reach while you’re at the grill.
Integrated into the side tables are convenient tool holders designed to keep your most important grilling utensils nearby. Instead of traditional hooks that can sometimes snag clothing, Weber uses smooth, rounded knobs that securely hold items such as spatulas, tongs, and grill brushes while remaining easy to access.
Many models also feature fold-down side tables, which can help save space when the grill is not in use. When cooking, however, these tables become essential prep stations—perfect for organizing ingredients, sauces, and finished dishes so your entire grilling process runs smoothly.
