HIG H ALT IT U DE D ERATE
Units may be installed at altitudes up to 610 m (2000 feet) above sea level without any modification.
At altitudes above 610 m (2000 feet), units must be derated to match gas manifold pressures shown in table below.
At altitudes above 1372 m (4500 feet) unit must be derated 2% for each 305 m (1000 feet) above sea level.
NOTE - This is the only permissible derate for these units.
