We just bought a Kenmore OTR microwave, which can either be vented to
the
outside (ceiling or wall) or vented inside (and use a charcoal
filter).
It
is a new install (no OTR present before)

Which is the better of the two?

1. I hear that with inside venting method, you don't have to worry
about
wind blowing and making noise, nor about the hassle of running the
vent
to
the outside air (either wall or ceiling). Sounds a lot simpler

2. You would think that the outside method would be more effective in
removing smoke and water vapour from cooking. You would also not have
to
worry about replacing the charcoal filter.

Comments / tips / suggestions / ideas / advice?

You already know the reasons. Now you have to make a decision. Outside
it
always better for eliminating odors, excess heat. Depends on how much
is
involved in venting outside.



To run it outside, I'll have to run the venting up into the about cabinet,
then into an inside an interior wall cavity about 24" (can I do this?) to
the ceiling. From there, can I run a flexible vinyl tubing to the roof?
I
am about 35" from an exterior wall. Which is best? (roof or wall)...

Should I run the venting up into the upper cabinet, then directly into the
back wall, up the wall (cut a 3 x 10 slot in the top plate into the attic,
then connect it to round pipe up to the roof to a roof vent?

Sound like a good way to do this? Should I just go directly up through the
bottom of the upper cupboard, then through the top of the cabinet, then
through the ceiling? Will the pipe from the cabinet to the ceiling be
visible? (we are putting in crown moulding but not right to the ceiling)...
anyone? You would see the pipe wouldn't you?
