As with many gas appliances, special consideration must be given to boiler installations at altitudes above 2,000 ft.
Table A-3 shows boiler de-rate per altitude. Example, Natural Gas boiler installed at 4,000 ft. must be de-rated by
10%.
For installations between 2,000 ft. and 5,400 ft., de-rates listed in Table A-3 is "natural de-rate". For installation
between 5,401 ft. and 10,100 ft., this de-rate is accomplished through use of smaller main burner orifice.
