It uses hot ignition so it should always light up, even when it is raining. The grill thermometer uses four sensors placed inside the grill so that the chef can tell the temperature of each cooking zone. The Fire Magic Echelon 660 also includes a stainless steel meat probe, halogen lights, a digital thermometer, cook zone dividers, a rotisserie rod storage and a feather-lite hood so you can open and shut the grill with ease.
