right now i'm running a knock off of a VC intreped. 6 inch single pipe about 4 feet up then a 90 into the thimble into the ss 6inch liner going about 23-25 up. i'm worried about getting the Blaze king. from reading on here after getting a load of coals going to load the stove then keep the damper open until the cat is in the operating range. right now it takes my stove about 10 minutes to get up untill the stove pipe temp is at or above 500*. this is when i close the damper. stove top is usally only 250* or so. how long does it take to engage the cat on one of these blaze kings? when its time to engage what temps are you guys running on the pipe(18 above collar, single wall)? after running the Neverburn i'm afraid of temps above 500* on the pipe. am i worring too much? right now i'm waiting on the dealer to call me back to see if i can come down and make a deposit tomorrow.a'm i worring for nothing? maybe i watch the stove too much? that dutchwest neverburn left a nasty taste in my mouth if ya know what i mean!
