The design brief for the CROSSRAY® was challenging from the very beginning: 1. Redefine the outdoor gas BBQ so that it can perform exactly like the fundamental and traditional outdoor way of cooking over a bed of red hot coals. 2. Create an even heat over the entire cooking area, and devise means to stop any fat are ups. 3. Incorporate a system that will also function as an infra red oven, in the way of traditional wood fired stoves such as the AGA. 4. Act as a true multi-function appliance, so the consumer needs only one outdoor appliance that can act as a pizza oven, normal oven, long slow smoker oven and an exceptional conventional grill.
