Owners of a gas range should visit the manufacturer's website to view the BTU rating for each burner. An average burner has approximately 7,000 BTUs, but individual ranges, and burners within a single range, can vary from 3,000 BTUs to 16,000 BTUs or more.
When visiting the manufacturer's website, consumers should search for the page for their particular gas range. The BTUs for each range are located in the specifications section of the Web page or within the range's owners manual. Some manufacturers, such as Viking, have a downloadable specification sheet that lists BTUs per burner, along with the range's dimensions and other pertinent information. The manufacturer may also recommend certain burners for different cooking methods based on the BTU rating.
