Well I will be selling my house this year, the realtor thinks that because my home already has a gas fireplace I should remove the wood stove before selling. Is there anyway I could remove the double wall up too the ceiling support box and plug it at the box? I would leave everything in place above the support box. What would I use to plug the flue? Pipe is 6 inch duravent double wall up too support box and triple wall above that. While it may not be the most economical to leave behind the components id rather not have to have the roof and drywall patched up. Any tips would be great and thanks in advance!
