I have an insert with a ss liner that is ovalized as it passes through the fireplace damper before returning to 6" round. I have not been able to get the oval section cleaned. The brush would get stuck and nothing I did could change that. Tried rope on the end, chain on the end, I even went to a 5" poly brush with no luck but this brush did go a little further down the pipe allowing me to put my hand (arm) up the pipe from the stove. What I realised is the stem of the brush was getting stuck in the "S" bend oval section. The stem is 11.5" long with an adapter. So now I need to buy or make a brush with a shorter stem. I just hope I didn't hurt the liner by tring to force it through.
If I could find an adapter for the 5" pellet brush I bought I would be able to put this to bed.
