{Based on altitudes from sea level to 2000 ft (610 m) above sea level. In th e U.S.A. for altitudes above 2000 ft (610 m), reduce input rating 4 percent for each additional 1000 ft (305 m) above sea level. In Canada, from 2000 ft (610 m) above sea level to 4500 ft (1372 m) above sea level, derate the unit 10 percent.
