Venting Design Specifications - Whirlpool YWML35011KW Instructions D'utilisation

This section is intended for architectural designer and builder/
contractor reference only.
NOTES:
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
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 are at least 3" (7.6 cm) of clearance between
the top of the microwave oven and the transition piece. See
"Rectangular-to-Round Transition" illustration.
