Types of Gas Grill

A recent trend in Gas Grill Valve is for manufacturers to add an infrared radiant burner to the back of the grill enclosure. This radiant burner provides an even heat across the burner and is intended for use with a horizontal rotisserie. A meat item (whole chicken, beef roast, pork loin roast) is placed on a metal skewer that is rotated by an electric motor. Smaller cuts of meat can be grilled in this manner using a round metal basket that slips over the metal skewer.
Another type of gas grill gaining popularity is called a flattop grill. According to Hearth and Home magazine, flattop grills "on which food cooks on a griddlelike surface and is not exposed to an open flame at all" is an emerging trend in the outdoor grilling market.

A small metal "smoker box" containing wood chips may be used on a gas oven safety valve to give a smoky flavor to the grilled foods. Although, barbecue purists would argue that to get a true smoky flavor (and smoke ring) the user has to cook low and slow, indirectly and using wood or charcoal. Gas grills are difficult to maintain at the low temperatures required (~225-250 °F), especially for extended periods.
