I am a new owner of a Levitt ranch on long island, the old owner seed he never used the fire place so I planned on getting it inspected before I used it but the storm left me with no power and heat. I inspected the chimney by looking up with a flash light and all looked good so a fire was lit and it kept me worm for 15 days with no power. Recently I discovered the dampener was not air tight so I went to home depo and got a window draft kit with the double sided tape and closed off both sides. I can’t believe how expensive custom doors are for a fire place and I can’t find used ones that are 35 by 21 high so for now I will not use the fire place. I think for what it’s going to cost me for two fire place doors and a new dampener I might as well just save the money and wait until I can get an insert
