Take the 2-minute tour ×  I know I need to check my local codes
before proceeding with this. that will be done but I first
wanted to ask this community for advice.  i'm going to have my
kitchen gutted to the studs in a couple weeks and the walls will
be open. the kitchen has vaulted ceilings and a recirculating
range hood (currently). I would like to install a vent that goes
outside as I will be installing a LP gas range.  the wall where
the vent would be goes up about 14ft. to the roof. there is also
a skylight directly above the area where the range is leaving
very little, if any room for an exhaust vent.  what I would like
to do is installed a box shaped vent between the studs in the
wall going up about 5-6ft. then exiting 90-degrees out.  i've
seen similar 90-degree gas exhausts on houses in the area. Then
again, I do live in the mountains though where many people do
not get permits and have things checked out.  So my question is:
Is it safer/better to have a straight vent through the roof? Or
is a 90-deg
