FRAMING SPECIFICATIONS
NOTE:
• The framed depth from a framed wall (item
“G” in the Framing Dimensions table
below) must always be measured from a
finished surface. If a wallcovering (such as
drywall) is to be attached to the rear wall,
measure the framed depth from the drywall
surface. This dimension MUST be exact.
• If the appliance is to be elevated above oor
level, a solid, continuous platform must be
constructed.
• The header may rest on the top metal
spacers; however, NEVER notch the header
to fit around the spacers.
• Consult all local codes.
