Char-Broil introduced its TRU-Infrared grills in 2012. Although the grills performed well, the manufacturer decided to add a few enhancements in 2015. When the company redesigned the Signature series, it upgraded the stainless steel in the emitters and burners.

The Char-Broil Signature 420 is a 4-burner liquid propane gas grill that easily converts to natural gas grill with the purchase of a conversion kit. TRU-Infrared is designed to give backyard chefs more control of the grilling process. According to Char-Broil, its TRU-Infrared cooking system ensures that food cooks evenly. We review these claims to determine if this is indeed the case.
Delivery and Packaging
Char-Broil does a good job of packing their products, and the Char-Broil Signature TRU-Infrared 420 Natural Gas Grill is no exception. In fact, one user described the packaging as “packed to withstand an airdrop.” Delivery was timely, with most buyers receiving the grill within three days of purchase.
Over 50 pieces require assembly. Buyers who purchased this product expressed that it was a challenge to put the grill together. However, they were pleased with the result. The grill assembly process took around three hours for one person to put together. Time was cut in half with the help of another set of hands.
Construction and Appearance
Sturdy metal construction and a silver and black body give the Char-Broil Signature TRU-Infrared 420 Liquid Propane Gas Grill a sleek look. Coats of paint dress the sides of the unit while the stainless steel shines on the lid, doors, and side shelves. It stands on four casters.
A thermometer rests in the center of the lid, which lifts with a tubular handle. Convenient double-doors keep the propane safe and out of view. The firebox holds porcelain coated grates and a stainless steel emitter and burners. There are three control knobs on the front of the unit that sit between the lid and the cabinet doors.
Facts and Figures
Before digging into Char-Broil’s claim, it is important to note the different types of heat used to cook on a grill: convection, conduction, and radiation. Convection heat flows around the food without touching it directly. The grilling term for this method is called indirect cooking. With conduction heat, flames make direct contact with the food. For example, roasting a marshmallow over an open flame is cooking with conduction heat.
With radiation, which is the method produced by Char-Broil’s TRU-Infrared system, the flames do not make contact with the food. Instead, it transfers the heat from the flames to a stainless steel plate to produce radiant heat. This is similar to the type of heat a microwave generates to cook food. Char-Broil figured out how to emit radiant heat by using a stainless steel plate to separate the flames from the grate, so it does not touch the food and now offer this technology in their grills, namely the Char-Broil Signature 420.
The three top ported burners are constructed of high-quality stainless steel and offer better heating and greater temperature control. The tubular burners generate a combined 25,500 BTUs. A lidded side burner is capable of reaching 13,000 BTUs.
The Char-Broil Signature TRU-Infrared 420 Natural Gas Grill weighs 131.4 pounds and measures 51.1 tall, 47.2″ wide, and 23.5″ deep. This unit comes with a 10-year warranty on the burners. The firebox, lid, grates, and emitters have a three-year warranty, and the rest of the parts are covered for a year.
Char-Broil attempts to take the guesswork out of cooking with the Signature TRU-Infrared 420 Gas Grill. A battery-operated ignition system starts the flame to the three stainless steel top-ported burners. The burners heat an emitter, which is a high-quality stainless steel plate with tiny holes. In doing so, the convection heat converts into infrared heat, creating a radiant surface to cook food without flare-ups.
The Char-Broil Signature TRU-Infrared 420 Natural Gas Grill offers 420 square inches of cooking space on porcelain-enamel cast iron grates. Additional space is provided on the 155 square inch warming rack, which also has a porcelain-enamel coating. The warming rack swings away from the main grilling area when the lid opens, allowing easy access to the food on the grates.
The cast iron grates are durable and easy to clean. They are engineered to hold and transfer heat. With TRU-Infrared technology, food cooks evenly and efficiently at desired temperatures while maintaining its juiciness. The holes in the stainless steel plates force the drippings to vaporize, which adds more flavor to meat and other food.
The Char-Broil Signature TRU-Infrared 420 Natural Gas Grill features a top-mount temperature gauge that monitors the grill’s temperature, so users don’t need to open the lid and let the heat escape to check on food.
Side shelves and casters offer convenience for prepping, moving, and storing. One of the side shelves has a lidded burner that flips up to boil sauces. The other shelf keeps grilling utensils within reach. Two of the four wheels lock to keep the unit stable.
In performance tests, the Char-Broil Signature TRU-Infrared 420 Natural Gas Grill received its highest score in the areas of evenness and indirect cooking. The grates get extremely hot (up to 650 degrees) and spread equally across the cooking surface.
The temperature range on the Char-Broil Signature TRU-Infrared 420 Natural Gas Grill allowed testers to control the temperature for low, slow cooking or grilling on high heat. Cooking with infrared heat resulted in tender, moist foods. Most importantly, because the food was not directly exposed to the flames, no flare-ups occurred.
