Vent materials needed for installation are not provided with microwave hood
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
not installing 2 elbows together, for optimal hood performance
If venting through the wall, be sure that there is proper clearance within the wall
for the damper to open fully.
If venting through the roof, and rectangular to round transition is used, be sure
there is at least 3" (7.6 cm) of clearance between the top of the microwave oven
and the transition piece.
