Note: The framed depth, 25-1/2" (648 mm)
from a framed wall, must always be measured
from a finished surface. If a wall covering such
as drywall is to be attached to the rear wall,
then the framed depth must be measured from
the drywall surface. It is important that this
dimension be exact.
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
The header may rest on the top metal spacers,
but must not be notched to fit around them.
Consult all local codes.
