Bought the brush and rods today. Trying to clean, but I am having trouble.... I am cleaning from the bottom up and am having trouble pushing the brush up. I can get about 11' up and then the rods just bend and I can't go any further. I need to go about another 7'. Any thoughts? I ran a few pieces of copper pipe over the rods to give some rigidness, but I only have about 10' of copper. I have gotten about 1/2 gallon of shiny flakey creosote so far, Is that a lot for only burning 2 1/2 months? I am a little concerned. Also, I have yet to do the stove pipe... It will be a pain, so I was thinking about waiting until after the burn season. Should I worry about it now? I burn 24/7 and I run the stove wide open for at least 1/2 hour each day to get things hot and clean. This is my first time cleaning, but this is a new install so again, I am a bit concerned about the half gallon I have gotten out so far. Please chime in. Thanks - Chris
