Broil King Signet 320 Review

Broil King Signet 320 Cast-Aluminum 3 Burner Liquid Propane Gas Grill

This is the Broil King Signet 320 Propane Grill. It’s a 3-burner, cast-aluminum, propane-fueled grill that achieves excellent grilling results. Let’s go through the features that make this grill a very high-quality system.

The cookbox is made of cast-aluminum, giving it a shiny metallic look on the outside. This aluminum construction also retains heat well, adding to the cooking efficiency. It also includes some parts made of steel, but these are zinc-coated and covered in powder-coat epoxy paint to prevent rusting.

The Signet 320 gas grill features sturdy wheels on the bottom to keep it mobile, and a pair of locking casters to keep it in place. Above the wheels is a cabinet with enough room for a propane tank and some extra grilling tools. The inside of the cabinet is made of steel, while the doors are stainless steel.

Above this cabinet are the control knobs. The Signet 320 LP gas grill has one control knob for each burner, so that’s 3 knobs in all. Each knob rotates at a wide 180º, so you can control the temperature more precisely, depending on your cooking needs. And below the middle knob is the electronic ignition. Just press the button to light it up.

On either side of the controls are two side shelves, giving you extra space to prepare other ingredients or store condiments while grilling. If you don’t need them (or have very little space for the grill), the shelves can be folded down, which is convenient.

On top is a roll-action lid that opens easily and smoothly. The lid is made of cast-aluminum, which keeps the heat locked in. Also, clearly visible in the middle of the lid is an analog thermometer. With this, you can monitor the temperature inside the grill every time. It is gradated both in Celsius and Fahrenheit, so no need to stress on converting between the two.

Inside is the actual grill assembly itself. It includes the stainless steel burners, an innovative heat distribution system (which they call Flav-R-Wave), and reversible cast-iron cooking grates. Each burner is a dual-tube system with more than 100 side ports on each tube. This distributes more heat across the cooking area. The stainless steel Flav-R-Wave components also assist in distributing the heat. They go just above the burners, and because of that the Flav-R-Wave also doubles as protection for the burner tubes. As for the grill grates, using cast-iron is a good choice, since this material both retains and conducts heat very well. This combination is responsible for the cooking quality of the Signet 320.

The grill grates in the Signet 320 provide a nice 400 square inches of cooking space. That’s enough space for several burgers and steaks all at once. And since the grates are cast-iron, it sears very well and transfers a good deal of heat to the food. Of course, that’s also in tandem with 40,000 BTUs of total heat output from the 3 burners. Overcooking and undercooking should be less of a problem too, because each burner has its own control knob. With this, you can cook more than one thing on the grill at a time.

One unique feature in the Broil King 3 Burner Gas BBQ is the reversible grill grate. One side is pointed, so use this if you want those signature sear marks on steaks. The other side has grooves to capture meat juices, so use this side when you’re doing continuous basting.

Speaking of juices, a common thing to happen in many grills is the juices and oils from meat falling off the grill grate into the burners. That may clog the burners later on, reducing their heat output. The Broil King 3 burner gas grill solves this through the Flav-R-Wave system. It protects the burners from dripping meat juices, while at the same time helping to lock in the flavor from those juices.

Here’s how the Flav-R-Wave works. This is much like a “roof” for the burners; it’s made of stainless steel and has angled grates, a bit like the corrugated metal used in actual roofs. But of course it isn’t fully enclosed; otherwise it would block the heat flow. So when juices and oils drip from the grill grates above, they hit the Flav-R-Wave frame first. Once they do, the juices are vaporized, and in turn the flavor rises back into the meat. In effect, the burners won’t get clogged, and whatever is cooking will taste better too. This technology isn’t perfect though, and with fatty meats, the drippings may still cause flare-ups at times.

A propane grill like the Signet 320 is generally large and heavy. Weighing at 61 kg, this grill isn’t meant for frequent short camping trips. Unless you have a heavy-duty truck, carrying this grill along often is not too practical. And that 61 kg is without the propane tank; likely it will weigh more when you include the fuel.

The wheels, however, do at least make the Signet 320 mobile. This would make it ideal for use outside the house, for the occasional outdoor barbecue. But because of the weight, it may not be good to use this gas grill on rough terrain. It will be much harder to move the grill around in rough ground.


  • ​Durable components
  • ​Well-built grill grates
  • ​Great performance from the dual-tube stainless steel burners
  • ​Independent temperature control for each burner
  • ​Has wheels for mobility


  • ​Heavy, not very portable
  • ​Drippings may flare up when grilling fatty meats
  • ​The cast aluminum on the lid and body is thin, as well as some other metal components

Overall though, the Broil-King Signet 320 is a good propane grill. With independent temperature controls, a high heat output, and sturdy construction, the Signet 320 can fulfill most of your grilling needs. It may not be quite as portable as smaller grills, but it compensates with more precise temperature control, faster cooking, and better heat distribution. And it still has the wheels to move around, so it doesn’t have to stay in one place all the time.
