OK thought I'd give a quick report for those wondering if they could do this themselves. It was super easy. I bought the 8"poly round brush and adapter and got the rods for free from that previous post. I have a zero clearance fireplace. Opened the doors took out the damper that just sits on side horizontal shelves. Attached one rod to the brush and sent it up around the 15 degree bend up the metal tube. As I pushed I added a rod and worked it up with an up and down motion adding rods as I worked up to the cap. Careful not to push too hard on the cap I reversed the order working it down taking a rod off each step.
Once done I brushed out the firebox sides and top and reinstalled the damper. Done! 20 minutes max. Got about 1/2 cup of very small dull granuals and lots of grey ash mostly from the firebox. I burn about 3-4 cords of dry wood each season and had the chimney cleaned by a pro for $175 before the start of last season. Hope this helps anyone thinking of saving themselves some money.
