grilles are available for a flush surface mount installation
that will trim out the wall can. The heater is designed to be
installed in the toe-space of a cabinet with a minimum of
2” overhang to maximum 7” of overhang. Shorter overhangs
may overheat the floor where longer than 7” overhangs
may overheat the cabinet door area.
