ADVANCE PLANNING

Ductwork Planning
• This hood may be vented vertically through upper
cabinets, soffit or ceiling. A duct transition piece is
supplied for vertical exhaust. Use locally supplied
elbows to vent horizontally through the rear wall.
See page 13.
• 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 ft. equivalent length for any duct
configurations.
• Refer to "Duct Fittings" chart to compute the maximum
permissible length for duct runs to the outdoors.
• Use metal ductwork only.
• A transition piece for 7 round duct is supplied. Use
"
7 round duct or you may use 3-1/4 x 12 rectangular.
• Install a wall cap or roof cap with damper at the
exterior opening. Order the wall or roof cap and
any transition needed in advance.
Kit – JXDW1
Order kit JXDW1 if your installation requires horizontal
ducting from the top of the hood through the back wall and:
• You have an 8 ft. ceiling and need to use a JXCH
Series Chimney Cover, or
"
• You have a 12 cabinet or 12 soffit that the hood is to
be mounted beneath.

3 1 ⁄ x 10 rectangular for through-the-wall venting.

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 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.
