MICROWAVE HOOD COMBINATION SAFETY

We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety
messages.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill or hurt you and others.
All safety messages will follow the safety alert symbol and either the word "DANGER" or "WARNING."
These words mean:
DANGER
WARNING
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury, and tell you what can
happen if the instructions are not followed.
This section is intended for architectural designer and builder/contractor reference only.
NOTES:
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 ventless (recirculating) 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. See
"Rectangular to Round Transition" illustration.
