NOTE: We provide this projection to aid In decision making. We believe our computations to be accurate.However,this projection is based upon and Is
directly dependent upon the accuracy of Input data provided to us as described in the attached CAL-Q-HEATO t System Conditions. Any changes
in these System Conditions may result in a change in the Heat Load Calculation.
