These are the basic configurations:
A660i: 75,000 BTUs Primary, 19,000 Backburner
A540i: 60,000 BTUs Primary, 19,000 Backburner
A530i: 60,000 BTUs Primary, 16,000 Backburner
A430i: 50,000 BTUs Primary, 16,000 Backburner
Electric ignition and digital thermometer are battery operated. Small battery boxes easily pop out from the sides of the control panel. All models are available with or without the rotisserie and the backburner raised above the cooking grate for rotisserie cooking.
For the s or stand-alone models add one 15,000 BTU side burner and one fold-out side table. All carts are made of 304 stainless steel. They include a retractable tool and paper towel holder, dual storage doors with six inch handles and heavy-duty swivel wheels. The smallest model, A430s, can be mounted on a post or pedestal instead of a cart.
A830i is a combo gas and charcoal side by side grill only offered as a drop-in. It consists of an A430i on one side and a matching charcoal grill on the other. The charcoal grill features a hand cranked adjustable height charcoal pan for easy heat control, easy access front door to add charcoal or wood and a 26,000 BTU charcoal igniter. Rotisserie and 16,000 BTU backburner are optional. The A830i has dial lid thermometers instead of digital (sigh).
