Ok so this is my first post on these forums. I recently bought my first house and there is a wood stove in the living room. I've used it a half dozen times since winter started and was told about creosote so I figured I should clean the chimney just to have a start to a cleaning schedule. Well I went and purchased a poly brush and the rods to attach to it tonight and after youtubing a bit I found you're supposed the slide the chimney pipe up at the slip joint and run the brush down through it into a bucket (or at least thats the method I liked) Anyways I attempted to break the slip joint free just to see how difficult it would be before attempting to clean it tomorrow and the entire chimney tube was able to move freely up and down through my roof once I got it out of the top of the stove. My question is, is that supposed to be able to happen? The slip joint did not seem to move, just the entire pipe assembly itself. Just wondering if something is horribly wrong with it. Thanks in advanced!
