    5 example: a genesis boiler is rated at 1,300,000 btu/hr. Input at sea level. At an altitude of 5,000 (1500m), the prejet orifices will decrease the input rate by 20% (= 4% x 5) to a new rating of 1,040,000 btu/hr. (= 80% x 1,300,000 btu/hr.) the input reduction is achieved by the prejet orifices th...
