3. CUSTOM HOOD PREPARATION
When building a custom hood, always follow all applicable construction codes and standards.
The custom hood frame must be sized to the shape and total weight of the insert assembly. Refer to the table below for total
weight of the insert, according to the type of blower chosen.

Start with the custom hood base, because its position will determine the
height of the insert. We recommend the base of the custom hood should be
3/4 inch thick plywood.
If an optional custom hood liner will be installed, we recommend the sides
and front of the custom hood to be 3/4 inch thick, assuming standard
cabinet widths. If the optional custom hood liner will not be installed, the
custom hood side and front thickness is at the installer's discretion.
The power cable must be a GFCI protected branch circuit.
Run power cable to installation location.
Stub out a 4 foot length of electrical cable below the custom hood.
4. SUGGESTED CUSTOM HOOD INTERNAL FRAMEWORK
The mounting holes for the 2 top stud supports are located at 11
from the insert base. The on center distance between the 2 studs is 30¼".
The mounting holes for the rear stud support are located at 1½" up from
the insert base. See illustration beside.
Once the custom hood base and frame are done, finalize the custom
hood.
5. INSTALL CUSTOM HOOD LINER (OPTIONAL)
The liners are specially designed to protect the exterior base of the
custom hood. Both models are adjustable for depth from 23½" to 26½"
(front to back, without backboard).
The liner must be installed before the insert. To order, refer to table
below to find the right liner model number for the custom hood width.
To view specific model information, including depths for each liner
model, visit www.BestRangeHoods.com or contact Technical support
(phone number listed on page 14, in warranty text).
To install, see instructions packed with the custom hood liner.
