Why doesn't my grill come with briquets?

Our newer Char-Broil and Thermos gas grills have been designed and tested to be used with Flame Tamers, Vaporizers, or heat distribution plates to provide more even heating, improve the cleaning process and reduce flare-ups. The addition of after market lava rocks, charcoal or briquettes of any type will cause poor combustion and increase the likelihood of a grease fire and is not recommended. Using briquettes, lava rock or charcoal in our grills, will void your warranty.
