Each component of GS4 was uniquely designed for ease-of-use and to provide an unequaled satisfaction to your backyard grilling experience.
DIRECT HEAT SETUP
Use the direct method for small, tender pieces of food that take less than 20 minutes to cook, such as: hamburgers, steaks, chops, kabobs, boneless chicken pieces, fish fillets, shellfish, and sliced vegetables.
With direct heat, the fire is right below the food. It sears the surfaces of the food, developing flavors, texture, and delicious caramelization while cooking the food all the way to the center.
INDIRECT HEAT SETUP
Use the indirect method for larger cuts of meat that require 20 minutes or more of grilling time, or for foods so delicate that direct exposure to the heat would dry them out or scorch them, such as: roasts, bone-in poultry pieces, whole fish, delicate fish fillets, whole chickens, turkeys, and ribs. Indirect heat can also be used for finishing thicker foods or bone-in cuts that have been seared or browned first over direct heat.
With indirect heat, the heat is on both sides of the grill, or off to one side of the grill. The food sits over the unlit part on the cooking grate.
BARBECUE MITTS
When in doubt, wear them. The good ones are insulated and protect both hand and forearm.
TIMER
Avoid the disappointment of torching your dinner by simply setting a timer. Nothing fancy needed—just one that is reliable and easy to use.
Preheat each and every time.
If the cooking grates aren't hot enough, food will stick, and you will likely never have a chance of searing properly or developing those handsome grill marks. Even if a recipe calls for medium or low heat, always preheat the grill on the highest setting first. Open the lid, turn up the heat, close the lid, and then let the cooking grate heat up for about ten minutes or until the lid thermometer reads 500°F (260°C).
Don't grill on dirty grates.
Tossing food onto the cooking grates before they have been cleaned is never a good idea. Leftover "stuff" on the grates acts like glue, binding it to the grates and your new food. To avoid tasting last night's dinner on today's lunch, make sure you are grilling on a clean cooking grate. Once the grates are preheated, use a stainless steel bristle grill brush to make a clean, smooth surface.
Be present in the process.
Before firing up your grill, make sure that everything you need is within arm's reach. Don't forget your essential grilling tools, already oiled and seasoned food, glazes or sauces, and clean cooking platters for cooked food. Having to run back to your kitchen not only means missing out on the fun, but could also result in burning your food. French chefs call this "mise en place" (meaning, "put in place"). We call it "being present".
Create a little elbow room.
Packing too much food onto the cooking grates restricts your flexibility. Leave at least one-quarter of the cooking grates clear, with plenty of space between each food item, in order to get your tongs in there and easily move the food around. Sometimes grilling involves split-second decisions and the ability to jockey food from one area to another. So give yourself enough room to operate.
Try not to peek.
The lid on your grill is for more than just keeping the rain out. Most importantly, it's for preventing too much air from getting in, and too much heat and smoke from getting out. When the lid is closed, the cooking grates are hotter, the grilling times are faster, the smoky tastes are stronger, and the flare-ups are fewer. So put a lid on it!
Only flip once.
What's better than a juicy steak with a deep sear and plenty of beautifully caramelized bits? The key to accomplishing these results is to keep your food in place. Sometimes we have the tendency to flip our food before it reaches the desirable level of color and flavor. In nearly all cases, you should turn food just once. If fiddling with it more than that, you are probably also opening the lid too much, which causes its own set of problems. So step back and trust the grill.
Know when to tame the flame.
When grilling, sometimes the most important thing to know is when to stop. The most reliable way to test doneness of your food is to invest in an instant-read thermometer. This slim little gem will help you pinpoint that critical moment when your food is at its best.
Don't be afraid to experiment.
Back in the 1950s, grilling meant one thing: meat (and only meat) charred over open flames. The modern day backyard chef doesn't need a kitchen in order to prepare a full course meal. Use your grill to make chargrilled appetizers, sides, and even desserts. Register your grill to receive special content that will inspire you along the way. We'd love to join you on your grilling adventures.
Using the TUCK-AWAY Warming Rack
Use the warming rack up to keep food warm or fold it down when not in use. To fold the warming rack down, lift rack slightly and rotate downward. Use heat-resistant mitts or gloves when adjusting rack.
What is Natural Gas?
Natural gas (NG) is a combustible, gaseous mixture of simple hydrocarbon compounds, usually found in deep underground reservoirs formed by porous rock. It is a fossil fuel composed almost entirely of methane. Natural gas is delivered by your local utility through an underground pipeline system.

Connect the Hose to the Gas Supply
A quick-disconnect fitting connects your grill to the gas supply. Gas will not flow unless the quickdisconnect is properly engaged.
What is a Leak Check?
Once the hose is properly connected, it is necessary to perform a leak check. A leak check is a reliable way to verify that gas is not escaping after you connect the hose to the gas supply. The fuel system in your grill features factory-made connections that have been thoroughly checked for gas leaks and the burners have been flame-tested.
WEBER recommends performing a thorough leak check after assembly, as well as annually. The following fittings should be tested:
Checking for Gas Leaks
Do not use a flame to check for gas leaks. Be sure there are no sparks or open flames in the area while you check for leaks.
Leaking gas may cause a fire or explosion.
Do not operate the grill if there is a gas leak present.
NOTE: Since some leak test solutions, including soap and water, may be slightly corrosive, all connections should be rinsed with water after checking for leaks.
Disconnect the Hose from the Gas Supply
Perform an Initial Burn-Off
Heat the grill on the highest setting, with the lid closed, for at least 20 minutes prior to grilling for the first time.
The Meal-To-Meal Maintenance plan includes the following simple, yet important, steps that should always be performed prior to grilling. Check for Grease Your grill was built with a grease management system that funnels grease away from food and into a disposable container. As you cook, grease is channeled down the slide-out grease tray and into a disposable drip tray that lines the catch pan. This system should be cleaned each and every time you grill to prevent fires.
Routine inspection of the hose is necessary.
Preheating the grill is critical to successful grilling. Preheating helps to prevent food from sticking to the grate and gets the grate hot enough to sear properly. It also burns off residue of a previously cooked meal.
After preheating, any bits of food or debris left over from previous use will be easier to remove. Cleaned grates will also prevent your next meal from sticking.
Do not line the slide-out grease tray or cookbox with aluminum foil.
Check the slide-out grease tray and catch pan for grease build-up before each use. Remove excess grease to avoid a grease fire.
Use heat-resistant barbecue mitts or gloves when operating grill.
Grill brushes should be checked for loose bristles and excessive wear on a regular basis. Replace brush if any loose bristles are found on cooking grates or brush. WEBER recommends purchasing a new stainless steel bristle grill brush at the beginning of every spring.
If the hose is found to be damaged in any way, do not use the grill. Replace using only WEBER authorized replacement hose.
Keep ventilation openings around tank clear and free of debris.
Each control knob operates an individual burner, and each burner ignites independently. Ignite the burners starting from left to right. All burners should be lit for preheating, however, all burners do not have to be lit while grilling.
To Extinguish Burners
Open lid during ignition.
Do not lean over open grill while igniting or cooking.
Each burner must be ignited individually by pushing the electronic ignition button.
If ignition does not occur within four seconds of attempting to light the first burner, turn the burner control knob to the off position. Wait five minutes to allow accumulated gas to dissipate, and then repeat the lighting procedure.
Searing is a direct grilling technique used on meats, such as steak, poultry parts, fish and chops. Searing browns the surface of the food at a high temperature. By searing both sides of the meat, you caramelize the food surface, creating a more desirable flavor.
Ignition of the sear burner is the same as ignition of a main burner, each burner ignites independently.
Note: Always cook with the lid closed to achieve maximum heat and to avoid flare-ups.
As you gain experience using the sear station we encourage you to experiment with different searing times to find the results that work best for your taste.
To Extinguish Burners
If one or more of the main burners on your grill are already lit and you would like to ignite the side burner, skip to step 3. If none of the main burners are lit and you are only using the side burner, start with step 1.
To Extinguish Side Burner
Open side burner lid during ignition.
Do not lean over side burner while igniting or cooking.
If ignition does not occur within four seconds of attempting to light the side burner, turn the burner control knob to the off position. Wait five minutes to allow accumulated gas to dissipate, and then repeat the lighting procedure.
Over time, the performance of your grill can diminish if it has not been maintained properly. Low temperatures, uneven heat, and food sticking to cooking grates are all signs that cleaning and maintenance are overdue. When your grill is off and cool, start by cleaning the inside, from the top down. A thorough cleaning is recommended at least twice a year. Consistent use may require quarterly cleanings.
From time to time you may notice "paint-like" flakes on the inside of the lid. During use, grease and smoke vapors slowly change into carbon and deposit on the inside of your lid. These deposits will eventually peel, and looks very similar to paint. These deposits are non-toxic, but the flakes could fall onto your food if you do not clean the lid regularly.
If you have been cleaning your cooking grates as recommended, the debris on your grates should be minimal.
FLAVORIZER BARS catch drippings that smoke and sizzle, adding flavor to your food. Any drippings that are not vaporized by the FLAVORIZER BARS are funneled away from the burners. This helps prevent flare-ups inside of your grill, and protects the burners from getting clogged.
Two areas on the burners that are key to optimum performance are the ports (small raised openings running along the length of the burners) and the spider/insect screens on the ends of the burner. Keeping these areas clean is essential for safe operation.
Cleaning the Burner Ports
Cleaning the Spider Screens
Turn your grill off and wait for it to cool before thoroughly cleaning.
Over time, the development of rough surfaces can form on the FLAVORIZER BARS. Wearing gloves is recommended when handling. Do not clean FLAVORIZER BARS or cooking grates in a sink, dishwasher, or selfcleaning oven.
When cleaning the burners, never use a brush that has already been used to clean the cooking grates. Never put sharp objects into the burner port holes.
Do not place any grill components onto the side tables as they may scratch the paint or stainless steel surfaces.
Do not use any of the following to clean your grill: abrasive stainless steel polishes or paints, cleaners that contain acid, mineral spirits or xylene, oven cleaner, abrasive cleansers (kitchen cleansers), or abrasive cleaning pads.
Located under the burners, the heat deflectors distribute heat evenly throughout the cookbox while cooking. Keeping heat deflectors clean will enhance the cooking performance of your grill.
Look inside the cookbox for any grease accumulation or leftover food particles. Excessive accumulation can cause a fire.
The grease management system consists of an angled slide-out grease tray and a catch pan. These components were designed to be easily removed, cleaned, and replaced; an essential step every time you prepare to grill. Instructions on inspecting the grease management system can be found in MEAL-TO- MEAL MAINTENANCE.
The outside of your grill may include stainless steel, porcelain-enameled, and plastic surfaces. WEBER recommends the following methods based on the surface type.
Clean stainless steel using a non-toxic, non-abrasive stainless steel cleaner or polish designed for use on outdoor products and grills. Use a microfiber cloth to clean in the direction of the grain of the stainless steel. Do not use paper towels.
Note: Do not risk scratching your stainless steel with abrasive pastes. Pastes do not clean or polish. They will change the color of the metal by removing the top chromium oxide film coating.
Clean painted, porcelain-enameled and plastic components with warm soapy water, and paper towels or cloth. After wiping down the surfaces, rinse and dry thoroughly.
If your grill is subject to a particularly harsh environment, you will want to clean the outside more often. Acid rain, pool chemicals, and salt water can cause surface rusting to appear. Wipe down the outside of your grill with warm soapy water. Follow up with a rinse and thorough drying. Additionally, you may want to apply a stainless steel cleaner weekly to prevent surface rust.
FOIL PANS
Perfect for lining the catch pan to make cleanup convenient and easy.
GRILL BRUSH
A must-use before you even dream of grilling. A quick once-over on hot grates prevents the charred remains of meals past from sticking to your meals present.
THERMOMETER
Small and relatively inexpensive, this gadget is essential for quickly gauging the internal temperature of the meat when grilling.

Checking the Ground Wire
Models 310, 315 and 435 have a ground wire connected to the manifold bracket. This is visible from beneath the control panel (D):
The cuts, thicknesses, weights, and grilling times above are meant to be guidelines. Factors such as altitude, wind, and outside temperature can affect cooking times. Two rules of thumb: Grill steaks, fish fillets, boneless chicken pieces, and vegetables using the direct method for the time given on the chart (or to the desired doneness), turning food once halfway through grilling time. Grill roasts, whole poultry, bone-in poultry pieces, whole fish, and thicker cuts using the indirect method for the time given on the chart (or until an instant-read thermometer registers the desired internal temperature). Cooking times for beef and lamb use the USDA's definition of medium doneness unless otherwise noted. Before carving, let roasts, larger cuts of meat, and thick chops and steaks rest for 5 to 10 minutes after cooking. The internal temperature of the meat will rise by 5 to 10 degrees during this time.
