NOTE: A flexible vent is not recommended. Flexible vents
create back pressure and air turbulence that greatly reduce
performance.
Recirculation: Non-Vented (Recirculating)
Installations Only
You will need to order:
Recirculation Kit part number W10807915 (See the
■
"Assistance or Service" section in your Use and Care
manual to order.)
You may also need a section of 3Z\v" x 10" (8.3 cm x 25.4 cm)
■
metal duct – length required is determined by the distance
from the exhaust outlet to the back flat surface of the
Recirculation Kit housing.
