5. INSTALL WOOD MOUNTING STRIP
Measure and mark a level line on wall above cooktop location for the wood mounting strip (see illustration below and
under step 2). Use #10 - 2’’ flat head screws to secure the mounting strip to the drywall. Make sure to hit the wall studs.
6. INSTALL THE HOOD
Rest the back cavity of the hood on the wood mounting strip.
Secure the hood to wood mounting strip with (4) screws #8 x
3
⁄4’’ (for 30’’
and 36’’ width hoods) or (6) screws (for 42’’ width and wider hoods)
provided at locations shown. Drill (2)
3
⁄16’’ size holes into the drywall for
wall anchors through the existing holes in the inside hood back in the
locations shown. Then, install the two wall anchors with the remaining
#8 x
3
⁄4’’ screws and the (2) washers provided.
CAUTION
Due to the weight of this hood, ensure that the wood strip
is attached to all of the available studs (2 studs minimum
for a 30’’ hood, more as wood width increases); not into
the drywall alone.
CAUTION
Hold the hood until it is completely secured to the wood
mounting strip.
4. INSTALL BACKSPLASH (OPTIONAL)
(Optional)
RMP Series
Backsplash must be installed before the hood shell because the hood shell covers the backsplash top mounting
screws. In order to be able to install the backsplash, make sure you have at least 18’’ clearance between bottom of
hood and range control panel or cooktop. (See instructions packed with backsplash.)
