• The high altitude ratings listed are Canadian Gas Association high altitude ratings and are valid only in Canada. In the U.S., the
National Fuel Gas Code, ANSI Z223.1-1988, recommends for high altitude installations above 2,000 feet, that the input rate be
reduced 4% for each 1,000 feet above sea level. - See page 14.
