Flush installation requires two side cleats to be attached
inside the cabinet frame, recessed from the front.
It is good practice, when oven is installed at the end of a
cabinet run, adjacent to a perpendicular wall or cabinet
door, to allow at least 1/4" space between the side of the
oven and the wall/door.
For oven support, install 2x4's extending front to back flush
with the bottom and the side of the opening. The supporting
base must be well secured to the floor/cabinet and level.
Note:
The conduit box must be located above the unit to facilitate
connecting and servicing.
The cabinet cavity must be plumb and the base must be flat
and level and capable of supporting a weight of at least 429
lbs (195 kg).
