This purchase was to replace an obsolete 10-year old 36" predecessor Profile model. 

GE makes no effort to facilitate the replacement of their obsolete 36" model with their newer 30" model. The air vents (exterior wall) on each are located differently thus forcing the 30" installation to be off-center and higher than 'normal' over the stove. This off-center install renders the GE 'trim kit' useless!!!
