I had a fisher insert installed in Aug. with a 7 in. stainless steel liner. I have it on the bottom floor of a 1900 sq ft split level and trying to heat the whole house and its not working to well. I put a door frame fan up but not doing to much to help. I've been looking for a blower for 2 months, very hard to find! Not sure why its not working, I know what these stoves are capable of. Any tips or ideas,and will a blower help me out. And does any one know where I can find a blower. Oh yea I'm burning oak cherry and ash.
