Does not include the concrete boiler pad or seismic brackets.
Note:
For altitude operation up to 4,999 feet, derate the input capacity by 3%/1000 ft.
For operation from 5,000 to 10,000 feet, with the electronic altitude adjustment made,
derate the input capacity by an additional 0.6%/1000 ft. for a total derate of 18%.
