* The high altitude ratings listed are Canadian Gas Association high altitude ratings and are only valid in Canada.
In the U.S., the National Fuel Gas Code, ANSI Z223.1/NFPA 54 recommends for high altitude installations above
2,000 feet, that the input rate be reduced 4% for each 1,000 feet above sea level.
