My SRG has a big pot kind of a thing liner that only has vent holes around the top and a drain hole in the bottom. Completely around that is the body of the grill with the burner in a big circle at the bottom under the pot liner. In the side is a bin you can put chips in that the smoke will fill the pot thru the vent holes around the top. On the top it has the optional grill. A lid covers all that making the smoke stay in longer. It is called true infra red because no actual flame or hot air from the flames do the cooking. It is the radiant heat from the pot thing.
