Hello - Another question from the noob with the wood stove, sorry... Doing another test run through tonight just getting the hang of it. Have the 2+ year seasoned and dry cord of wood coming later this week but still testing with the dryest of the stuff cut this past spring. Still having some minor fights getting the secondary to go (not a very cold night but the coldest in the next couple weeks up here, plus kind of raw with the rain so a good night to do another "practice run"). I still noticed that air rushing sound. I had previously chalked it up to the intake underneath the Oslo but I experimented and grabbed a dollar bill and did what I imagine the dollar bill test to be... I just held the bill around where it sounded like the noise was coming from - where the Double Walled pipe (Selkirk Metal Bestos.. It is the inside piece that extends.. black smoke pipe down in the room of the stove) connects to the adapter we bought from the stove shoppe (they don't sell Metalbestos there and suggested we use the ICC connector/adapter.. Just a simple piece of metal that fits inside the flue of the stove and inside the 6" double walled piece (because of the way it is built and the way the Oslo's flue flares out, it doesn't fit over without this). Sure enough, at the sides and back of this connection point, the dollar bill grabbed right hold of the crack. That leads to two questions: 1.) Is this an issue? The draft is great here (more on that on Question 2) so smoke/CO/heat/etc are going up but does this mess with the efficiency, create any condition to be concerned about? 2.) I know these newer Non-Cat EPA stoves don't need dampers but can you have too much draft? I forget what we had installed for pipe throughout the house but I am sure the chimney is at least 24'-26' high, probably closer to 27-30 and it is a straight shot. We live on top of a hill (about 50' shy of the highest point in time just up the road), the roof line is taller than any nearby trees and we are a very windy location - windy enough to always have a clear driveway with powdery snow and big drifts around..
