Quadrafire AE Insert into old non-masonry chimney. When the winds are blowing harsh outside, I can feel air come in around where the insert sides and the surround meet. Any suggestions on what I can do?
Cold in NY said:The unit is vented up my old nonmasonary chimney. Didn't realize about a block-off plate or insulation. What material should I use for the block-off plate? Is there a certain distance it should be above the unit? What kind of insulation should I use? Thanks for the help!
