due to the weight and size of the hood.
1. Measure from range top to desired hood bottom
and mark line A. (26" minimum from range top).
2. Plum and mark center line.
3. Mark hood height line B.(18-7/16" from line A)
4. Mark mounting spread from C/L.(8-7/8" on line B)
5. Fasten(2) M4X 1-1/2" screws into studs on line B
but do not tighten all the way. Note: Wood
blocking may need to be added behind the
drywall if no studs are present. Wall anchors may
also be used but check local codes for

and screws to hold the weight of the hood could
result in personal injury or damage to cooking
surface or counter.

wall just below the celling or soffit using (2) M3 X
1" screws.
