This section is intended for architectural designer and builder/contractor
reference only.
NOTES:
●
If installing for recirculation, venting must be routed up and out through an
exhaust register (not provided) in a kitchen soffit. A charcoal filter kit (not
provided) should be used. See “Assistance” section for information on ordering.
●
Vent materials needed for installation are not provided with microwave hood
combination.
●
We do not recommend using a flexible metal vent.
●
To avoid possible product damage, be sure to vent air outside, unless using
recirculation installation. Do not vent exhaust air into concealed spaces, such as
spaces within walls or ceilings, attics, crawl spaces or garages.
For optimal venting installation, we recommend:
●
using roof or wall caps that have back draft dampers
●
using a rigid metal vent
●
using the most direct route by minimizing the length of the vent and number of
elbows to provide efficient performance
●
using uniformly sized vents
●
using duct tape to seal all joints in the vent system
●
using caulking compound to seal exterior wall or roof opening around cap
●
for optimal hood performance, do not install 2 elbows together
If rectangular to round transition is used, be sure there is at least 3" (7.6 cm) of
clearance between the top of the damper assembly and the transition piece. See
“Rectangular to Round Transition” illustration.

NOTE: The minimum 3" (7.6 cm) clearance must exist between the top of
the damper assembly and the rectangular to round transition piece so that
the damper can open freely and fully.
