I bought my home with a wood burning fireplace that i would love to use. However there seems to be a piece missing. I think after my researching its called a flute? Its the piece that you open to let smoke out when using the fire place. Right i have one of those balloons you seen on tv covering the hole so i don't loose heat from my central heat. I would love to use the fireplace for free heat every chance i get. However its a pain to keep removing that balloon and installing it back after im done. Anyone have suggestions Ive heard of a piece to stick on your chimney outside with a long rod inside the chimney and i open it when i need to. However i aint getting on that steep roof. Any help?
