I have a chimney that has 2 flues. One is a 9†by 9†and right nect to it is a 9†by 13â€. My furnace is vented out the 9 by 9 so I ran an insulated 6 inche ss liner down the 9 by 13 flue. I noticed that there was a whole in the back of the 9 by 13 flue like someting was being vented there but I am not sure what it wold be. I am positive the furnace is vented through the other flue. Is it ok to have run the liner down that flue.
Any opinions would be helpful
Thanks

Also do you recomend drilling self taping screws throught stove pipe connectors-even if they fit together very snugly?
