When you do your sweep this weekend do you plan on removing all that single wall pipe from inside the house and cleaning it outside? I have a set up in our lower level with about four feet of single wall pipe and two 90s that I pull off the stove and slide out of my thimble and take it outside to clean. In my case it's the only way I could clean that section of pipe. I think you can do a better job of cleaning it outside where you can see what you're working with and can give it a good scrubbing with a metal brush. With your set up it looks like it could be hard to clean with a brush if you leave it hooked to your stove with those offsets.
yeah that what i planned on doing. i only have enough sticks to do the upper section anyway. 12ft. i will do the lower sections outside.
