Working with Chattanooga, TN, U.S.-based Burner Systems International (BSI, www.burnersystems.com), the appliance maker improved the BTU power from 16k to 18k on the strongest burner.
"It is much more difficult to achieve good carry over and low turn down with the star shape, but in doing so we created much better pan coverage, especially while simmering," says Christian Gallitz, cooking product marketing director.
"As for the overall design, a lot of thought was put into the porting system, as well as the distribution and mixing system within the burner (venturi) in order to have the correct mixing of gas and air in order to optimize efficiency, flame spread, noise, combustions, etc.," he continues. "Just as demanding was determining the burner locations and overall cooktop design, in order to optimize pan spacing, burner performance, and pass all CSA temperature standards for built-in cooktops."
Another design focus was making the burners easier to clean. "The burner sits slightly back on the volcanoes, so there are no cracks where food could get in," Gallitz says. "Also, by having the ports in the burner base instead of the burner cap, we have improved cleanability."
