overhang of 12 inches (305mm) in front of the cooking
equipment or according to the homologation stickers
affixed on the kitchen exhaust hood.
Validate with the kitchen exhaust hood shop drawings
for dimensions to install the kitchen exhaust hood at
the right place (hood orientation, hood position in
cooking island, etc.).
When the kitchen exhaust hood is on the floor, place a
protection material under the hood to avoid damages
to the stainless steel.
Weight validation
Perform validation of the weight of each kitchen
exhaust hood according to the hoods weight table to
make sure your anchorage and methodology are
appropriate to the weight of the component.
Lifting, suspension and levelling
Fix the anchor points to the building’s structure
according to the position of the kitchen exhaust hood
mounting brackets and install 7/16 inches (11mm)
threaded rods in the anchor points according to the
positions of the brackets. See below for the typical
positioning of exhaust hood mounting brackets
without
spacer for the combustible material
clearance.
Adjust the length of threaded rods to respect the
kitchen exhaust hood height installation.
Lift the kitchen exhaust hood and fix the hood with the
threaded rods. All of the kitchen exhaust hood
mounting brackets must be held by a threaded rod.
Adjust the height of the hood via the threaded rods
bolts installed in the mounting brackets to level the
kitchen exhaust hood.
When lifting an island exhaust hood with assembly
joints, we suggest proceeding to the assembly of the
sections on the ground and then lifting the whole
assembly of the exhaust kitchen hoods. Refer to
annex 2 for assembly.
IMPORTANT
Maintain the kitchen exhaust hood
relatively levelled when lifting to avoid
flexion and torsion of the hood. We
highly recommend to use a lifting device
such as Genie Lift.
During installation of multiple kitchen
exhaust hood, we highly recommend to
use a laser level device. Each mounting
bracket must be used for the suspension
of the kitchen exhaust hood.
Connection of the kitchen exhaust hood collar
IMPORTANT
According to the NFPA96 code, the duct
must be at minimum made from 16
gauge steel or 18 caliber stainless steel.
The duct must be welded entirely and
waterproof.
Sometimes there are openings made in
factory on the kitchen exhaust hood.
Always make sure that these openings
are not obstructed for future installation
of components on site.
The connection of the exhaust collar must be made
with a full and continuous welding. While welding,
protect the stainless steel surfaces to avoid
contamination.
