Parkboy,
Can't do it now since it has all been siliconed. Before the stove cement/mortar was first put in the seams/joints, I did do a similar smoke test with a cigarette. I did see evidence of it pulling smoke, but since the stove was hot, it was hard to continue. When the stove is hot, it and the pipe puts out enough heat that it will actually "draw" the smoke up beside the pipe at a good rate of speed. This is because hot air rises.
