I didn't want to hi jack someones thread so I figured I would start my own. I have a roughly 27' chimney with a stainless steel 6" liner that goes from the fireplace insert up through the chimney to the top with a cap. I want to clean the liner as I have not done so and have been burning since October and would like to see build up or lackof first hand. My insert is a Hampton I300. I would like to clean from the bottom up as the roof is covered in snow/ice but am afraid of gaskets, removing guts, etc. Does anyone have the skinny on how to do this? Also in the spring I would like to get on the roof and clean is there anything I should know before attempting the top down method?
