3. BUILD FRAMEWORK
• When cutting or drilling into wall, do not damage electrical wiring and other hidden utilities.
• When building framework, always follow all applicable construction codes and standards.
Construct wood wall framing that is even with the surface of wall studs.
Wood wall framing must be at least 1/2" thick and 3" high. Fasten wood wall
framing to wall studs for a solid installation.
Make sure that the height of the framing will allow the mounting bracket to be
secured to the framing within the dimensions shown (see illustration at right).
After wall surface is finished, using a level, draw a vertical line up to the
ceiling starting from the center of the planned hood location. Carefully center
and level the hood mounting bracket over installation location. Secure it to wall
using 3 no. 8 x 1½" Phillips flat head screws.
4. INSTALL UPPER FLUE MOUNTING BRACKET (DUCTED INSTALLATION ONLY)
Center the upper flue mounting bracket with the center line previously
drawn in step 3 and place it flush with the ceiling. Use the upper flue
mounting bracket as a template to mark the position of its screws.
Secure the upper flue bracket to the wall using 2 no. 8 x 1½" Phillips flat
head screws. Make sure that the bracket is tight against the wall.
5. INSTALL PLENUM (NON-DUCTED INSTALLATION ONLY)
Center the plenum (included in the non-duct kit) with the center line previously
drawn in step 3 and place it flush with the ceiling. Use the plenum mounting
slots as a template to mark the position of its screws.
Secure the plenum to the wall using 2 no. 8 x 1½" Phillips flat head screws.
Make sure that the plenum is tight against the wall.
