Type: Large models

Specs
Size Size categories are grouped according to our measurements of primary cooking area. Small is 330 square inches or less (about 15 four-inch diameter burgers); medium is 340 to 490 (about 18 to 24 burgers); and large is 500 and over (over 30 burgers). Size	Large
Number of main burner controls Most small and average-sized grills have two separate burners, controlled independently, or one burner with independently controlled halves. Some average-size grills have up to four burners with corresponding controls; large grills often have six. Additional burner controls generally allow the cook more flexibility. Number of main burner controls	5
Igniter type Most grills have a mechanical igniter of either the push-button or rotary design. More convenient is a battery-operated electronic igniter, which usually ignites the gas on the first try. Some grills also have lighting holes, on the side of or beneath the grill, that can be used with a match should the igniter fail. Igniter type	Rotary
Wheels and casters Most carts have two wheels or casters on one end and two casters on the other. Other models have just two wheels: you lift one end to move them. Wheels with a full axle are better than those bolted to the frame, which may eventually bend. Wheels and casters	2 wheels & 2 casters
Natural-gas version available Many gas (that is, propane gas) grills also come in a natural-gas version, usually with a different model number that includes an "N" for natural gas. Some models have a conversion kit (as standard or optional equipment) that requires some modification to a propane grill in order to use it with natural gas. If you're unfamiliar or uncomfortable with these modifications, you may need to hire a professional to do the job; your retailer should be able to help with arrangements. The grill also would, of course, require its own gas line. Natural-gas version available	Yes
Propane tank included Most models don't come with a propane tank, which cost about $25 to $30 to buy separately. Propane tank included	No
Bare-cast-iron grates The grill's primary cooking grates may be made of bare cast iron, which generally sears meats well and keeps grilling temperatures consistent. Bare cast iron, however, must be kept oiled to prevent rusting. Such grates are also usually more difficult to clean than other surfaces. Bare-cast-iron grates	No
Coated-cast-iron grates The grill's primary cooking grates may be made of porcelain coated cast-iron, which generally sears meats better and keeps grilling temperatures more consistent than grates made of porcelain coated steel. The porcelain coating usually makes such grates easier to clean than other surfaces, and the grates should resist rust as long as their porcelain coating isn't chipped. Coated-cast-iron grates	Yes
Coated-steel grates Primary cooking grates made of porcelain-coated steel will resist rust as long as their porcelain coating isn't chipped. Porcelain-coated grates are also usually easier to clean than other surfaces. But coated-steel grates typically do not sear meats as well or keep temperatures as consistent as sturdier grates made of cast iron or stainless steel. Coated-steel grates	No
Stainless-steel grates Primary cooking grates made of stainless-steel are generally sturdier than those made of coated steel and resist rust even without a porcelain coating. Stainless-steel grates	No

Features
Long-warranty burners While burners remain the grill's most-replaced part, most are warranted for only 3 to 5 years. Better burners are covered for 10 years or more. Long-warranty burners	No
Side burner A side burner, which resembles a gas-stove burner and has its own heat control, is handy if you want to cook vegetables or sauce without leaving the grill. Side burner	Yes
Rotisserie This generally means that the grill comes with a dedicated rotisserie burner; the motor and spit are usually purchased separately. A dedicated rotisserie burner is usually located on the back of the firebox, slightly above the cooking grates; some models use the grill's main burner(s). This feature allows you to roast meat (a whole chicken, for example) very evenly, yielding a flavor that some people prefer to that of grilled food. . Rotisserie	Yes
All or mostly stainless Includes more than just a panel or other trim. Based on our limited tests, nonmagnetic stainless is less likely to corrode. All or mostly stainless	Yes
Side shelf material Shelves are usually made of plastic, though a few are made of wood, cast aluminum or stainless steel. Plastic, cast aluminum and stainless steel are the more durable materials. Side shelf material	Stainleess steel
Fuel gauge Located on the propane tank or the grill itself, this reveals at a glance how much propane remains in the tank. Fuel gauge	No
Infrared burner Gas burner that uses infrared technology (ceramic burner, plates and screens, or troughs as some examples) for cooking. An indirect flame is used for cooking food. Burner can be located as the main burner, side burner, rotisserie burner, or any combination of burners. Infrared burner	Rotisserie, side burner
