Miele DA 229-2 - Manual (Page 24)

The majority of the weight of the in-
stalled ventilation system will be
supported by retaining plate A. It
must be firmly attached to the stud
framing behind the drywall. If studs
are not available in the required lo-
cations, a plywood backing (min.
1 /
2
"
(13 mm) thick) spanning at least two
studs must be installed. Failure to
adequately support the weight as
stated may result in the ventilation
system falling off the wall, causing
personal injury and property dam-
age.
(If plywood backing is not needed, pro-
ceed to "Attaching the retaining plates
to the wall." )
To install a plywood backing board
^ Make a mark,
S + 16

" (425 mm)
above the cooktop and on the center-
line.
^ Make a second mark 12 3

"
(324 mm) underneath the first one.
^ Hold retaining plate A against the
wall so that the marks are visible
through the holes of the plate (see
"Installation / Retaining plate A").
Draw a line around the plate’s perim-
eter, then set aside the plate.
^ Make a cutting line 3" (76 mm) above
and 3" (76 mm) below the outline of
plate "A".
^ Find the studs to the left and right of
the mounting location by tapping the
wall or using a stud finder.
^ Mark a vertical cutting line along the
center of each stud.
Be careful not to damage any wiring
or plumbing that may be located be-
hind the wall. Make sure that the
power supply to the area where this
installation is being performed has
been turned off at the breaker panel
before cutting into the wall.
^ Remove the drywall between the cut-
ting lines and replace it with plywood
of a matching thickness (min.
1
/
2
"
(13 mm) thick). Tape the joints and
refinish the wall.
^ Proceed to "Attaching the Retaining
plates to the wall" to complete the in-
stallation.
