Adjustments
1. Determine the correct gas input rate. Refer to the unit rating plate.
The input rating for altitudes above 2,000 ft. (610 M) must be
reduced by 2 percent for each 1,000 ft. (305 M) above sea level. For
installations below 2,000 ft. (610 M), refer to the unit rating plate.
For installation above 2,000 ft. (610 M), multiply the input on the
rating plate by the derate multiplier in
rate.
