Furnace gas input rate on furnace rating plate is for installations at
altitudes up to 2000 ft. (610 M).
In the U.S.A.; the input rating for altitudes above 2000 ft. (610 M) must
be reduced by 4 percent for each 1000 ft. (305 M) above sea level.
In Canada, the input rating must be derated by 10 percent for altitudes of
2000 ft. to 4500 ft. (610 M to 1372 M) above sea level.
The Conversion Kit Rating Plate accounts for high altitude derate.
