| 主权项 | 1. The A furnace comprising: an induced draft blower; an inducer motor driving the induced draft blower; and a furnace control determining a modulation percentage, the furnace control controlling RPM of the inducer motor in response to the modulation percentage; wherein in a first range, the furnace control controls the inducer motor RPM based on the equation: inducer motor RPM=RPM1×MODULATION %/K1 where RPM1 is a value derived from a reference RPM, MODULATION % is the current modulation percentage and K1 is a reference modulation percentage. | ||
