The FEC500 gets up to temp in 10 to 15 minutes, features electronically-controlled heat, and an amazing 15 minute heat recovery time. The FEC500 uses 100% food grade wood pellets, which provide pure wood smoke flavor, economically. Ash is cold and is removed by the cupful, rather than the trash-can-full. No more risk of dumpster fires! Because it is 100% wood burning, you won’™t get gas fumes passing over your meat, which means a much better tasting product than you can get with gas-fired pits.
