Installed a new telescoping stovepipe on the stove with the improperly-connected liner (another thread, two weeks back) today. Opened two windows earlier this evening, one on either end of the family room, to ventilate the smoke coming off the fresh paint on the new tube. It seemed to do the trick. Was just in bed, and then thought of those two windows. Ran downstairs to check, and found I had forgotten to close them. It may be an indication of just how draft this place is, that we had two windows open for an hour or two, and failed to notice any real difference.
