Step 1, Determine Ductwork And Wiring Locations - GE Monogram ZV30R Installation Instructions Manual

STEP 1 DETERMINE HOOD, DUCTWORK AND WIRING LOCATIONS
• Use a level to draw the cooktop centerline location.
Draw the line to ceiling height.
• Measure desired distance from the bottom of the hood
to the cooking surface.
Note: If you are installing the hood with duct covers, be sure to read
"Using Duct Cover Accessories" page 7. Exact installation height
may be determined by use of one or more duct covers.
• Determine bottom
of hood location
(Dimension A) by
subtracting 12-1/2"
from the desired
installation height.
• Use a level to draw a straight horizontal pencil line
indicating the bottom of the hood.
• From the line indicating the bottom of the
hood, measure 20" up and draw another line for
the location of the wood support. See illustration.
House Wiring Location:
• The junction box is fastened to the back of the hood
on the right side.
14-1/4"
Electrical
Area
• The recessed back side of the hood provides a large
area for the house wiring to exit the wall and be
routed to the rear knockout and junction box.
• The location for the house wiring depends on the
installation height of the hood and the width of the
hood. See shaded "Electrical Area" for locations.
• Remove junction box cover and knockout. Install
strain relief.

FOR VERTICAL (Straight Up) DUCTING:
• Use a level to draw a centerline from the bottom of the
hood to ceiling or soffit.
• If venting out the ceiling, extend the centerline
forward on the ceiling or soffit.
• Locate the centerline of a 10-1/2" hole on the ceiling
or soffit by measuring 6" from the wall.
FOR DUCTING THROUGH REAR WALL:
• Measure 9-7/8" above the marked line for the top of
the hood. At the centerline, draw a horizontal line to
mark the location for a 10-1/2" diameter hole.
Alternate Knockout Locations (for soffit installation)
If the installation requires, the junction box can be
relocated from the back to the top of the hood. Remove
3 screws, align box to top knockout and secure with
original screws.
• Remove junction box cover and knockout. Install strain
relief.
