ABSTRACT:
A blower unit for releasable attachment to the slotted front panel of a wall heater. The blower unit includes a blower having an inlet, an outlet, and a motor-driven rotor for generating an air flow between the inlet and the outlet. A housing is attached to the blower and has a first opening aligned and communicating with the blower outlet thereof for receiving an air flow therefrom. The housing has a second opening spaced from the first opening, and a pair of spaced projections are carried by the housing and insertable in a slot of the front panel of the wall heater for mounting the housing and thereby the blower in an operative position on the front panel externally thereof with the second opening adjacent to and aligned with at least one slot so that, when the blower is energized, air will flow into and through the housing and out of the second opening into the wall heater through the one slot to cause heated air in the heater to be forced out of the other slots of the front panel. A thermostatic limit switch carried by the housing senses the temperature of the air flowing out of the wall heater to control the operation of the blower.
