    Hello everyone! My first post.

    I have just purchased my first home which has a two flue chimney. I pan on putting an insert into the Fireplace, which is one one flue. The second flue is connected to the oil furnace in the basement, but also has a 'thimble' (?) opening in the kitchen which has since had a metal cap put on it. I assume this would have been for a kitchen stove at one point?

    I am wondering what the proper way to seal up the opening would be?

    Not to step on toes here, but there is a much better and safer product than those for this purpose.

    Insert, tighten screw and the flue is sealed air-tight and insulated from the dwelling. Eliminates the need to furnace cement a flue stop in and is definitely going to seal better.

    I was actually thinking that it might be good to block the opening to the thimble at the flue, as it currently acts as a bit of a shelf that debris can build up on (which after re-reading moondogs post is what he was suggesting too).

    When I took of the cover that is there now (made of galvanized metal) there was some buildup in the opening.
