NOTE:
Ratings are shown for elevations up to 2,000 feet (610M) above sea level. Above 2,000 feet (610M), input must be derated 4% for
each 1,000 feet (305M) above sea level. When units are installed in Canada, any reference to derations at altitudes in excess of 2,000
feet (610M) are to be ignored. At altitudes of 2,000 to 4,500 feet (610 to 1372M), the units must be orificed to 90% of the normal
altitude rating, and be so marked in accordance with the ETL certifi cation.
