In the equation at the top of Table 8 change “,S,SS = ” to “LS,SS= ”. 28 Table 8 Fuel Characteristics and Parameters for Calculating Steady-State Sensible Heat Loss (LS,SS) and Steady-State Efficiency (EffSS). Under CF (5) for No. 2 Fuel Oil replace “1.5029209 x 10-16” with “1.5029209 x 10

Replace the current equation for burner operating hours (BOHSS) and add a new variable K4as shown below. Replace the current equation for BODSS BOHSS = 2080(0.77)(A)(QOUT/(1 + ) 2080(B) with the corrected equation BODSS = 2080(0.77)(A)(QOUT/K4)/(1 + ) 2080(B) Add the new variable K4 as defined below. where K4 = Conversion factor, 1000 Btu/kBtu or 1000 Btu per hr/kBtu per hour
