ADVANCE PLANNING
Ductwork Planning
•These vent hoods are equipped for 10" round ductwork. For best performance, use 10" round ductwork on the 48" wide hoods. 30" and 36" hoods may be transitioned to 8" round.
•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.
•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 150 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.
•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.
Wall Framing for Adequate Support
•These vent hoods are heavy. Adequate structural support must be provided. Hoods must be secured to vertical studs in the wall.
•It is 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.
Decorative Duct Covers:
Decorative duct covers, 6" and 12" high, are available to fit all models. The duct cover conceals the ductwork running from the top of the hood to the ceiling or soffit. Stack one or more duct covers over the top
of the hood to reach your ceiling height.
