A heater assembly includes a heating element assembly having a resistive heating element connected to a housing member. First and second guide members are oppositely and outwardly positioned with respect to the heating element assembly and extend away from the housing member. A patch plate includes an installation aperture and first and second wings extending away from the patch plate. The first and second guide members are positioned to individually slidingly engage with one of the first and second wings thereby defining a track system to permit the heating element assembly to be slidingly received through the installation aperture without contact between the resistive heating element and the patch plate.
