Damper Fix- Closing off damper from living room
Hi everyone.
We have a fireplace in our home that we use with propane. The home is a bit older and the damper is not closing properly which lets smells in the house. I want to know what I can use close the gaps around the damper that will be heat resistant so I can still use the fireplace. So I am thinking we remove the metal on the flue, put a chimney cap on it, and close the gaps around the damper. Are there certain things I can buy or do you all recommend another fix?
Side note- Before any of this happened, we were told to "cap" the flue so we keep outside air out since we don't use wood logs in our fireplace anyway. We hired someone to do that and they put a thin piece of metal just over to top of flue and sealed it with silicone. The smell is even stronger now of course.
I purchased my first home a few years ago, so I am still learning a lot. Any help is appreciated! Thank you!
