9.3 Burners Per Pump

1.The maximum number of burners per pump is shown in Table 11.

2.When combining different burner inputs in a system, the number of burners per pump (0' - 2,000' altitude) is given by the sum of their inputs:

a.EP-100 up to 500,000 Btu/h max, but not more than 4 burners.

b. EP-200 up to 750,000 Btu/h max, but not more than 6 burners.

c. EP-300 up to 1,600,000 Btu/h max, number of burners is limited to the maximum number of burners listed in Table 11 for the largest input model used.
