Scott see this is where they have me. I did the install, and then they came out and did the fire inspection. From day 1 as soon as they saw that I did not use there product duravent, the blame has been on the pipe. Granted The first section of pipe was defective, the new pipe is awesome. When you look at the gasket picture above you do not need to be a stove mechanic to see the obvious signs of a leak around the gasket. One thing for sure is I am a stubborn SOB, and I will not take defeat until no hair on my head is left pulled out. I can not wait till this weekend to see if what I did worked. .
