Selecting the Venting Direction
The range hood can be used for either horizontal, vertical or ductless air discharge.
Your range hood is supplied with a 3-1/4" x 10" damper frame for a transition
piece from the hood to the ducting. Below is a brief ducting installation description.
Your installation will depend on whether there is an existing ducting or whether you
need to install a ducting run. For the best performance, use the shortest possible
ducting path and the least amount of elbows when discharging horizontally or
vertically.
Vertical Discharge – Vertical discharge is the most
common method of hood installation. If your kitchen has
an attic space above, the ducting may be run through the
cupboard and the attic to a roof cap. Use a 7" round
duct (not included).
Another option, if your kitchen has a soffit above the
cabinet, is to run the duct up into the soffit and then discharge the air horizontally
through the outside wall to a wall cap.
Horizontal Discharge - If the range is located against
an outside wall, then horizontal discharging is ideal,
provided there are no obstructions such as wall joists or
places where openings are difficult to make.
If a wall cap is used directly off the back of the hood, special care must be taken to
ensure that the damper in the damper/duct connector on the hood and the damper
in the wall cap do not interfere with each other when the range hood is operating.
This could result in either inadequate air delivery or back drafts. If this condition
exists, remove the hood damper flap. Sometimes when using a wall cap, it is easier
to duct vertically and than to use an elbow.
Ductless – In ductless installations, air is vented back into
the kitchen through the opening in the range hood grille.
If you do not anticipate heavy cooking, this method may
be preferable. Ductless installation requires the use of a
charcoal filters (included) to remove odors, which should
be replaced at regular intervals depending on use. Check
with your local retailer or dealer for replacements.
Note: This filter is not dishwasher safe!
It will not be necessary to remove any duct knockouts, however you must remove the
vent cover from the slots on the front of the rangehood. Save the vent cover for
possible future use.
