Hi , I'm in a process of installing Free Standing Stove (Osburn 2400) in existing fireplace in my basement . It;s going to be almost like insert. The liner is going to be connected all the way in a back. Not a lot of space to work around. Wondering how i'm going to clean it. I have insert with bypass upstairs and cleaning it is a breeze . Just opening bypass and sweeping whatever falls. How do you clean insert with no bypass and tight space around it?
