What is the required area around a microwave that is required for air
flow? We're in the middle of a kitchen remodel. We've been told we
are required to have a microwave trim kit for a full-sized microwave
in order for their to be sufficient air circulation. The trim kit,
however, is awfully large and is really cutting back on our pantry
space.

Is a trim kit required for a microwave to be within a cabinet? Again,
is their a minimum distance required around the microwave to assure
proper air flow?

Thanx much for your help.
