Advance Planning
DUCTWORK PLANNING
•This hood is designed to be vented vertically
through the ceiling. Use locally supplied elbows
to vent horizontally through the rear wall.
•Determine the exact location of the vent hood.
•Plan the route for venting exhaust to the outdoors.
•Use the shortest and straightest duct route
possible. For satisfactory performance, duct run
should not exceed 100′ equivalent length for any
duct configurations.
•Refer to “Duct Fittings” chart to compute the
maximum permissible length for duct runs to
the outdoors.
•Use rigid metal ductwork only.
•This vent hood must use a 6″ round duct. The
6″ round duct can transition to 3-1/4″ x 10″
or 3-1/4″ x 12″.
•Install the house duct to run horizontally between
ceiling joists or straight up through the roof.
•Install a wall or roof cap with damper at the
exterior opening. Order the wall or roof cap
and any transition and length of duct needed
in advance.
WARNING:
TO REDUCE THE RISK OF FIRE,
USE ONLY RIGID METAL DUCTWORK.
WALL FRAMING FOR ADEQUATE
SUPPORT
•This vent hood is heavy. Adequate structural
support must be provided. The hood must be
secured to vertical studs in the wall. See page 9
or 14.
•We strongly recommend that the vent hood with
duct cover be on site before final framing and wall
finishing. This will also help to accurately locate
the ductwork and electrical service.
•Installation will be easier if the vent hood is
installed before the cooktop and countertop are
installed.
ADVANCE PLANNING
A duct cover accessory may be required for your
hood installation depending on ceiling height.
