Like many others here I have been battling an overdraft situation ever since I installed my PE Spectrum in late 2007. I have 22' of 6" Class-A and 6-7' of doublewall stovepipe. If I leave the air control open when I reload I can get the inside pipe of the doublewall glowing dull red within 7-10 minutes at the connection to the stove, flames are shooting right up the pipe. (I can see this because of the hole used for the keydamper in the outside section of the doublewall)
Every year I try something new to calm this thing down and I'm thinking of switching to singlewall pipe to see if that would help. I have installed a pipe damper, changed the door and glass gaskets, and verified ash dump is sealed. All is good from the stove end, the damn stack is sucking like a vacuum. Last season when I cleaned the chimney I removed the stovepipe and just the section of Class-A could suck a kleenex right out of the house when the outside temp was around 50F. I've heard of people happy they could get some cigarette smoke to go up their stacks, mine could almost take the butt right out of your hand.
Would switching to single wall help much??? I can easily get outside doublewall pipe temps of 600F 18" up from the stove with the air control shut all the way down. Those readings are using an IR thermo. I really feel like a barometric damper would be the best cure but I get why those are frowned upon so I'm thinking of trying the pipe next.
