The Saber® Infrared Cooking System uses a patented combination of an emitter plate, cooking grate and burner box design that does not use lava rock, charcoal or briquets.  The Saber® IR Cooking system will provide more even heating, improve the cleaning process and eliminate flare-ups. 

The addition of after-market lava rocks, charcoal or briquets of any type will cause poor combustion and increase the likelihood of a grease fire and is not recommended.  Using briquets, lava rock or charcoal in our grills will void your warranty.
