Abstract

In a fixed-firing rate induced draft furnace, having a heat exchanger and an integrated control inducer motor, an improved method of controlling excess air characterized by the steps of: providing at least one pressure switch that is responsive to a preselected pressure drop level in the heat exchanger, the pressure drop level being selected so as to be commensurate with a theoretically desired excess air level under firing operating conditions: accelerating the integrated control inducer motor until the pressure switch closes and thereupon recording a first motor speed and a first current level: calculating a first torque value based on the first motor speed and the first current level: and regulating torque applied to the integrated control inducer motor in accordance with the first torque value.
