Ducting Recommenda- tions
Overall Dimensions
The hood can be ducted to the outside or used with a recirculation unit. The recir- culation unit is available from your dealer.
For the most efficient air flow exhaust, use a straight duct run or as few elbows as possible.
Do not use flex ducting. Always use metal ductwork with minimum diameter of 6” (150 mm). A transition is necessary to connect to larger diameter ductwork or to square ductwork.
COLD WEATHER installations should have an additional backdraft damper installed to minimize backward cold air flow and a nonmetallic thermal break to minimize conduction of outside temperatures as part of the ductwork. The damper should be on the cold air side of the thermal break. The break should be as close as possible to where the ducting enters the heated portion of the house.
Always install a metal vent cover where the ductwork exits the house.
The overall dimensions are:
•Width: 35 1/2" (900 mm); 30” (760 mm)
•Depth: 20 1/2" (520 mm)

Mounting Requirements The hood must be mounted through the back wall. It cannot be mounted from above. See “General Information” on page 2 for suggestions for determining hood height.
For safety purposes, the wall must be able to support three times the weight of the hood. See “Minimum Weight Requirements” on page 3 for the minimum amount of weight the wall must support. Note: At least one screw must be installed through a stud.
