HIGH ALTITUDE INSTALLATION

For elevation above 2,000 feet, derate furnace input 4% for each 1,000 feet of elevation above sea level. Derating is

accomplished by reducing the orifice size. See Derating Chart for orifice size.

In Canada, for elevations from 2000 to 4500 feet derate by reducing gas manifold pressure to 3.0" W.C. for natural gas and 9.0" W.C. for LP gas.
