When deciding on different gas grill models, you need to look at the number of burners the grill contains as well the number of BTU's it generates. A higher number of burners and BTU's means that the grill will generate more heat and will be better suited when you have a large amount of food items to grill. You will also need to decide if you want a permanently installed grill or a portable one on wheels, both models are available from Copperfield Chimney Supply.
