PREPARING FOR HOOD INSTALLATION
Plan where the ductwork will be located. See pages 9-12 for rough-in dimensions. Install proper-sized duct work, and
roof or wall cap for the type of blower you are using. Adjust your measurements for various heights of ceilings, soffits,
cabinets, or ranges/rangetops.

INSTALLING HOOD CANOPY (Indoor/Outdoor VWH Models Only)
Center the wood strip (provided locally - see drawing for dimensions) and attach to wall. Using the slot located on the
backside of the canopy, place the hood onto the wood strip. Secure the hood to strip with mounting screws provided.
Make sure that the wood strip mounting screws are driven into the framing and not just the drywall. Use additional
mounting screws (and wall anchors if necessary) in the other holes.
NOTE: BECAUSE OF
THE WEIGHT OF THE
HOOD - MAKE SURE
THAT THE WOOD STRIP
MOUNTING SCREWS
ARE DRIVEN INTO THE
FRAMING AND NOT
JUST THE DRYWALL. IT
MAY BE NECESSARY TO
DRILL ADDITIONAL
HOLES IN THE CANOPY
FOR PROPER
ALIGNMENT.
HEIGHT OF INDOOR HOOD
The bottom of the hood should be 30” (76.2 cm) min. to 36” (91.4 cm) max. above the countertop. This would
typically result in the bottom of the hood being 66” (167.6 cm) to 72” (182.9 cm) above the floor. The bottom of the
hood should never be more than 72” (182.9 cm) above the floor or more than 36” (91.4 cm) above the countertop.
These dimensions provide for safe and efficient operation of the hood.

HEIGHT OF OUTDOOR HOOD
The bottom of the hood should be 30”
(76.2 cm) to 36” (91.4 cm) above the grill
surface. The hood should be installed 4-
1/2” (11.4 cm) plus the distance between
the back trim and surface from the back
wall. (NOTE: There is a 3” minimum
clearance from the back trim to non-
combustible surfaces and a 24” minimum
to combustible surfaces.) This will require
building the hood out from the wall. Any
combustible material used for this purpose
must be covered with locally supplied
stainless steel. It is also recommended a
backsplash be used with outdoor
installations.
