Weber Genesis II LX S 340 Gas Grill

Introducing the all new Weber Genesis II LX gas grills series:  featuring the new GS4 system which includes an independent electronic ignition for each burner, revolutionary stainless steel high performance burners, new Flavorizer bars with flame view window and a Grease Management System. The new Infinity electronic ignition system is ensured to ignite. These new high-tech burners have a unique tapered shape to ensure a consistent and constant gas flow from front to back, providing even heat distribution across the entire cooking surface.  The Flavorizer bars help reduce flare-ups, improve heat distribution, and enhance barbecue flavor.  Also, the Flavorizer bars feature a new flame view design so consumers can easily see the flame.  The Grease Management System helps funnel away grease while reducing the risk of flare-ups. Drippings that are not vaporized by the Flavorizer bars are channeled into an easy-to-remove drip tray, located within the catch pan under the cook box. This allows for faster, easier clean-up.

The stainless steel Weber Genesis II LX S-340 features three stainless steel burners with High heat setting that produce 43,500 BTUs of power and a newly designed side burner yielding 12,000 BTUs of power. The Weber Genesis II LX S series gas grills are equipped with 7mm stainless steel cooking grates, stainless steel Flavorizer bars and stainless steel heat deflectors to effectively hold and distribute heat evenly over the 513 square inches of primary cooking area.  The Tuck-Away warming rack provides an additional 156 square inches for a generous 669 square inches of total cooking area. The control knobs light up with a push of a button for night time grilling. One powerful LED handle light illuminates the entire cooking area of the grill. The stainless steel hood has a center-mounted thermometer to monitor the internal cooking temperature. The welded tube frame with enclosed cabinet includes: two storage shelves, two side shelves providing prep space with the left side shelf folding down, two heavy-duty locking casters and two large wheels.  Hang your essential grilling tools on the three convenient built-in tool hooks.  The Liquid Propane (LP) models have a new tank location. Mounting the gas tank to the outside of the grill makes the tank easy to access and remove. The easy-to-read LED fuel gauge lets you see how much fuel is left in the tank (LP models only). The natural gas (NG) models include a 10-foot flexible hose.

The Genesis II LX S series grills are iGrill 3 ready. The iGrill 3 Bluetooth Thermometer (sold separately) can be installed right into the side table of the Genesis II, making it easy to monitor cooking time and temperatures, sending alerts straight to your mobile device! Connect up to four temperature probes and monitor your food all at one time. The free Weber iGrill App, available in the App Store or Google Play store, is your central dashboard that monitors the temperature and receives alerts. The Weber iGrill App comes loaded with digital grilling tools such as custom alarms, exclusive recipes, temperature graphing and social sharing. The In-App features also include fuel level detection and knob light control.
