Should I Close the Flue on My Fireplace When Not in Use?
Yes. Make sure you close the flue or damper on your fireplace when it’s not in use, and that it’s sealed tight. Your home’s warm air can go right up the chimney at the rate of up to 400 cubic feet each minute.
Check the seal on the fireplace damper by closing it off and holding a piece of tissue paper inside the firebox. If drafts blow the tissue around, repair or replace the damper.Back to All FAQs Ask Us a Question
