Pre-Installation (continued)
6 . For ducted installations, adjust old duct work or install included
new duct work, as necessary, by following these guidelines:
-
Your venting system must vent to the outdoors vertically through the
roof .
-
A straight, short duct run will allow the hood to perform most
efficiently. Long duct runs, with elbows and transitions will reduce
the performance of the range hood . Use as few of them as possible .
-
Use round metal duct work with a uniform diameter of
6 in . (152 mm) (included) . Larger ducting may be required for best
performance with longer duct runs .
-
Before making cuts, make sure there is proper clearance within the
ceiling or wall for the exhaust vent.
-
Fasten all connections between pieces of duct with sheet metal
screws and tape all joints with certified duct tape.
-
Cap the exterior of the duct with a soffit cap or roof cap.
INSTALLING THE MOUNTING PLATE
Due to the size and weight of this range hood, the mounting plate must be
firmly attached to the ceiling.
-
Ensure the supplied fastening hardware used to secure the mounting
plate to the ceiling is appropriate for your ceiling type . Consult a
professional installation technician if you are unsure .
-
For plaster or drywall (gypsum) ceilings, the support must be
attached to wood joist or trusses . If this is not possible, a support
structure must be built behind the plaster or drywall . Once a suitable
structure is in place, secure the mounting plate to the structure using
the supplied wood screws (AA) in the locations identified in Fig 4.
-
For concrete ceilings, expansion bolts (EE) must be used to secure
the mounting plate . Position the mounting plate around the vent
opening and mark the locations of the mounting fasteners
-
Remove the mounting plate and drill holes for expansion bolts in the
marked locations using a hammer drill and a 8 mm concrete drill bit .
The holes should be 50 mm deep to ensure the expansion bolts are
seated firmly in place.
-
Next, secure the mounting plate to the ceiling using expansion bolts
and ensure it is mounted firmly in place.
-
Check to ensure the supplied power cable is long enough to reach
your grounded electrical outlet . See "INSTALLING THE WIRING" for
more details .
