For well-done steak, the meat should be cooked more slowly about four inches from the heat source. A broiler, whether gas or electric, must be pre- heated, but there is no specific recommended time. Each model varies according to its size and style. Whenever possible, check the manufacturer's recommendation. Using a broiler properly improves food quality and saves energy and time.
Improper use can be hazardous.
The best instructions are in the manufacturer's manual, which makes specific safety and usage recommendations. Food cooks in its own juices with no added liquid or fat. Broilers cook by radiant heat. The wave length produced by a heat source determines how a particular food will cook. In broiling, heating first occurs at the surface of the food where the radiant energy is absorbed.
