Abstract: A furnace blower assembly includes a blower housing a blower and a motor. The blower is positioned within the housing and is adapted to rotate relative to the housing. The motor is coupled to the blower. The housing defines an outlet having an external periphery and an internal periphery. The external periphery or the internal periphery of the outlet is adapted to be fitted to a portion of the external periphery or the internal periphery of the duct. The outlet defines a longitudinal axis. The outlet has a peripheral edge and a protrusion extending outwardly from the external periphery or the internal periphery of the outlet. The protrusion is spaced from the peripheral edge of the outlet and is adapted to abut the peripheral edge of the duct.

Abstract: A motor controller for a burner system includes an inverter that supplies current to a motor that rotates a draft inducer fan. A processor is coupled to the inverter and receives a signal from a system controller, and in response instructs the inverter to supply a first current, during a first period, to the motor to rotate the fan to produce a first mass flow through the burner system, the first mass flow having a first mass flow rate greater than a threshold to actuate a vacuum switch. The processor then instructs the inverter to supply a second current, during a second period starting at an expiration of the first period, to the motor to rotate the fan to produce a second mass flow through the burner system, the second mass flow having a target mass flow rate for normal operation of the burner.
