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.

MINIMUM FURNACE CLEARANCES
Access for servicing is an important factor in the location of
any furnace. A minimum of 24 inches should be provided in
front of the furnace for access to the heating elements and
controls. This access may be provided by a closet door or by
locating the furnace 24 inches from a facing wall or partition.
These furnaces are design certified for the following minimum
clearances from combustible material in alcove or closet
