Do I need to caulk the joints of my wood stove pipe?
When I look at the joints of the pipe on my wood stove, I can
see that there isn't  a tight fit. Should I try to caulk this?
Won't the smoke come out there when the stove is going?
When a chimney is drafting (i.e. when it is hot enough for the air
in it to raise) the smoke will not only go up, but air from the room
will be drawn into the spaces where the pipes join. If smoke
comes out there, you either don't have the fire hot enough to
provide for draft or the chimney is plugged.
